This is Dr. Casey Albin. Today, I'm interviewing Dr. Wendy Ziai and Dr. Vishank Shah about their article on intracerebral hemorrhage. This article appears in the April 2026 Continuum issue on cerebrovascular disease. Welcome to the podcast. I am so delighted that both of you are joining. To begin, let's just do a brief introduction of who you are and, and a little bit of how you got interested in the topic.  Dr Ziai: Hi, I'm Wendy Ziai. Thank you for having me on this podcast. I am a professor of neurology at Johns Hopkins. I am a neurointensivist, and I think I got primarily interested in this topic through clinical trials that I have been a part of since my fellowship days.  Dr Shah: Hi, everyone. I'm, uh, Vishank Shah. I am also, uh, very thankful for being invited to be a part of this podcast. I'm also a neurointensivist at Hopkins and the fellowship program director here for neurocritical care, and I'm interested in recovery after ICH, and that's why I'm a part of this work.  Dr Albin: Welcome to you both. It is such a treat for me to get to interview fellow neurointensivist, particularly those who have such a wealth of experience. So, I am delighted to dive into this. All right. So, to set the stage for our audience, intracerebral hemorrhage has long been approached with pessimism. But your article really highlights that there are meaningful advantages in prevention and risk stratification and long-term recovery for these patients. Though you both are neurointensivist, this article really emphasizes primary prevention and the holistic long-term care for the survivors. And so, to begin, Dr. Shah, can you just lay out a little bit for our listeners the scope of intracerebral hemorrhage and its community impact?  Dr Shah: Yeah. So, you know, ICH is the second most common type of stroke. There are more than three million new cases of ICH globally each year, and it accounts for thirty percent of all stroke types, but it is the one that has the highest mortality, with more than forty to fifty percent of the patients dying in the first thirty days, and then continued long-term impact on both functional as well as outcomes, as well as survivorship after the early period. And it also disproportionately impacts lower socioeconomic, and then minority races like Blacks, Asians, as well as Hispanic ethnicity. And so, there's a lot of work that needs to be done to reduce the burden of this disease.  Dr Albin: Absolutely. I mean, these can really be devastating for families, and I really am appreciative of your highlighting that there's a lot of disparities, and there's a lot of work to be done to really increase equity to these patients. I think a lot of this goes into really the AAN's focus on brain health and trying to improve some of what we're doing to maintain brain health. And I really wanted to kind of drill down on this because for ICH, there's a lot that can be done upfront as we think about how do we counsel patients who may walk into the office about strategies to prevent ever becoming an intracerebral hemorrhage patient. So, Dr. Shah, can you walk us through a little bit about what neurologists in the community need to be doing to make sure that no one ends up with us in the neurointensive care unit?  Dr Shah: Yeah, sure. So, I think, you know, one of the most important risk factors is, of course, hypertension and long-standing uncontrolled hypertension. And so really recognizing the need for early onset screening with regular blood pressure monitoring at a very early age, particularly in the races that I discussed earlier. And then I think another big part, obesity, metabolic syndrome, and type two diabetes. And I think there's a lot of interesting new work that with the GLP-1 agonist, you know, in a large multicenter cohort studies showing that patients receiving these had a significantly lower reduction risk of ICH. And so, this might be a really important part that, you know, clinicians need to start increasingly recognizing and using in their practice. And then, of course, other risk factors that are common include smoking, diet high in sodium, exposure to air pollution, both indoor as well as outdoor. And so, mitigating all of these risk factors can also reduce the burden of ICH.  Dr Albin: Absolutely. And I really want to highlight that hypertension plays such an important role and that we as neurointensivist, as community neurologists, really need to be creative about ways that we can help people meet those blood pressure target and meeting people in the community where they are, making sure that they're not suffering from side effects from their medication that would prevent them from sticking with it long term. Dr. Ziai, anything else to add about what we can do in the community?  Dr Ziai: So, we really want to emphasize, even in the acute phase, that patients moving forward need to have targeted interventions to reduce blood pressure, smoking, enhance their physical activity, have a diet that is high in fruits and vegetables and low in alcohol and salt, and then promoting weight loss, of course.  Dr Albin: And Dr. Ziai, I'm gonna ask you a little bit about one of the things that maybe not all of our listeners have heard about is this APOE2, APOE4 genetic risk for intracerebral hemorrhage. What's going on there and, and should clinicians be testing for that? Dr Ziai: That's a great question, and it is not one that we currently test people for at least acute ICH presentation. APOE2 and A4- E4 alleles, these give patients a two to three times higher risk of ICH by increasing cerebral amyloid deposition. And if you happen to have APOE2 carrier ship status, then along with other risk factors like white matter disease and vascular risk factors, these predict the onset of new microbleeds even during very short follow-up periods of about two years. And as we know, having cerebral microbleeds are associated with an increased risk of all strokes, ischemic and ICH, but they are one of many MRI markers of small vessel disease, which along with cortical superficial siderosis, does significantly increase future ICH risk. And so even in people who've never had an ICH, if they happen to have an MRI, it may be reasonable to look at the MRI and incorporate this burden of small vessel disease, and especially these hemorrhagic markers into, uh, decision-making about interventions.  Dr Albin: That's a really excellent point. And so, I think that your article did a really beautiful job of thinking holistically about the patient, incorporating clinical markers of their risk for having ICH, but also those radiographic markers. I'm just gonna ask you to summarize those again one more time because not everyone will be familiar with these. So, when you're looking at an MRI, what are the things that you're particularly clued in on that would increase the patient's risk of future ICH?  Dr Ziai: In the past, what we're looking for really is markers of cerebral amyloid angiopathy, which significantly increase a person's risk for lobar hemorrhage in particular. And so, we have a set of criteria called the Boston Criteria, and there's a new version of these, version 2.0. And these, um, incorporate a number of imaging markers that provide a very high sensitivity and specificity to diagnose CAA after an ICH. But even if someone's never had an ICH, and they evaluate that risk-benefit ratio for different cardiovascular prevention strategies. And so, the markers that we're specifically interested in are, of course, microbleeds. But not just having microbleeds, but are they lobar or are they deep? Lobar having a higher risk for lobar ICH. How many microbleeds are there? Is it greater than five, or is it just one or two? Also, cortical superficial siderosis is a marker, a hemorrhagic marker, that does portend a significant increased risk of recurrent ICH, along with having a lobar ICH. And now we have these new markers, which are the white matter hyperintensity multi spot pattern, which requires these hyperintensities on flare imaging in the subcortical area, having greater than at least ten of these multi spots, and also having enlarged perivascular spaces in the centrum semiovale, and having at least twenty of those. And finally, white matter hyperintensities, which can be measured with the physica score or just by visualizing them. We can look at white matter hyperintensities as well as being a measure of small vessel disease.  Dr Albin: Got it. And so just to summarize, we're looking for small vessel disease markers because that puts our patients at higher risk of ongoing future bleeds. And then we're also looking for markers of particularly small vessel disease that's caused by cerebral amyloid angiopathy, which again, because it's having that protein deposition, that puts the patient at risk of those leptomeningeal very small vessels, putting the patient at risk of lobar ICH. Just confirming I've summarized this all correctly.  Dr Ziai: Yes. That was perfect.  Dr Albin: Amazing. Dr. Shah, I'm gonna go back to you. Let's say we have a patient. Let's say this is a sixty-five-year-old man who comes in and they want follow-up and they're... And you're trying to think about they've had an ICH in the past, and they are also at risk for ischemic disease. Let's say they, they have hypertension, they've had a smoking history. They have some risk for ischemic events. And you're trying to think about how do you balance those. Let's say the patient needs to be on aspirin but does have some of those high-risk features on their MRI. Is there any guidance on how we think through preventing them from having a recurrent bleed if they're a high-risk patient, also preventing them from having an ischemic event, which they might be at high risk for as well?  Dr Shah: Yes. So, I think, you know, the first step is of course trying to understand what was the type of bleed. I think that has a very important role, like you mentioned. If it's a lobar hemorrhage versus a deep hemorrhage, the risk of recurrent ICH and ischemic events is very variable. So lobar hemorrhages, there's obviously a higher risk of recurrent hemorrhage events, whereas deep hemorrhage is actually at or behaves sort of like small vessel ischemic strokes and have a higher risk of recurrent arterial ischemic events. So that distinction in itself can help you gauge which patients would be safe and would benefit from these therapies. To begin, and of course, looking for some of these markers on MRI that were mentioned by Dr. Ziai for recurrence of hemorrhage risk. In terms of antiplatelet, the, there is a lot more data now to guide treatment, and we have the RESTART as well as the ESTART trial that showed that starting an, a single antiplatelet after intracerebral hemorrhage did not increase the risk of hemorrhage recurrence. They were very variable in the timing when aspirin was started, and so that remains still a question about what is the safest time point to start aspirin. For example, in the ESTART trial, they started them very early, within the first three days, whereas in  the RESTART it was all the way up to two months after the hemorrhage. And so... But in general, the risk of recurrent ICH was very low with a single antiplatelet agent. And so, if it's needed for ischemic prevention, it's relatively safe broadly across all types of hemorrhages.  Dr Ziai: Yeah. I would just mention that there was also a subgroup analysis of the RESTART trial using MRI. And so, this more than likely included patients with CAA, since 40% of the hemorrhages were lobar in that study, and therefore seeing that there was no increased risk of recurrent ICH in RESTART, it is thought that putting patients back on their antiplatelet therapy is safe.  Dr Albin: That's a really huge takeaway pearl for our listeners, that regardless of whether it's a lobar bleed or a deep bleed, if there is a strong indication, you know, this is not just, oh, because someone gave them aspirin 81, but truly that there is a reason that they need to be on a single antiplatelet agent, it probably benefits them to be on that agent, and there's good data that there's not a huge increase in risk. Summarizing all of that?  Dr Ziai: Great.  Dr Albin: Now, things are gonna get a little bit tricky here, because what if the patient, what if they need to be on dual antiplatelet therapy? Or what if they need to be on anticoagulation? Dr. Ziai, I'll, I'll throw that to you. How do you tackle that patient population?  Dr Ziai: Yeah, the safety of dual antiplatelet therapy hasn't really been studied in patients who've had a prior ICH. Although, in people who've had previous strokes, putting them on dual antiplatelets doesn't seem to increase the risk of ICH, but it does increase extracranial hemorrhage. And so there may be other reasons not to put patients on dual antiplatelet agents. Patients who have cancer and also cardiovascular or cerebrovascular disease, putting them on dual antiplatelet therapy does seem to increase the risk for intracranial hemorrhage. So, I think there is enough of a bias against DAPT therapy in patients who have had an ICH that we would not recommend DAPT for patients with a prior ICH.  Dr Albin: Absolutely. And, and then what about, let's say they have atrial fibrillation, and you know that they have a high CHA2DS2-VASc score, and they are at very high risk of ischemic events, but they've also had a prior intracerebral hemorrhage. Walk us through a little bit, how should we approach that patient? Dr. Ziai, I'm gonna start with you again.  Dr Ziai: Sure. So again, looking at the MRI, which all patients with ICH should have nowadays. If patients do have these hemorrhagic findings, a lobar ICH, evidence of CSS, cortical superficial siderosis, especially if it's disseminated, and also lobar microbleeds, especially if there are greater than five, if they're multiple, then anticoagulation should really be avoided in those patients.  Dr Albin: Absolutely. So, I'm really hearing that when we have a patient with ICH, it is just critically important that we understand is this a hypertensive bleed or is this a lobar bleed that is probably related to cerebral amyloid angiopathy? And getting to that distinction is going to play a major role in our deciding whether or not the patient can be on DAPT or can be on anticoagulation. And then what are some of the strategies for patients that you're referring them to if they really cannot tolerate being on anticoagulation, but they have atrial fibrillation, and they do need some sort of ischemic stroke prevention?  Dr Shah: There's still a lot of controversy, even in non-lobar hemorrhages, about resuming anticoagulation and when that would be safe. HAF trial, there was a reduction in ischemic stroke recurrence, uh, but a significantly higher increase in hemorrhage recurrences. I think that trial included both deep and lobar hemorrhages. So, we still need more data, and I think the ASPIRE trial and maybe a meta-analysis would answer that eventually. But in the meantime, if a, specifically for lobar hemorrhages, which are, uh, thought to be CAA related, if they, uh, and the patient has AFib, you know, where anticoagulation would be contraindicated, a watchman device or, you know, AFib ablation may be some of the other strategies that can be looked into for those patients specifically.  Dr Albin: Right. I think that's a really important point to emphasize, that we don't just don't give up and say, "Oh, you're not a candidate for anticoagulation," but we really reach out to our cardiovascular friends and say, "Hey, what other procedures can you offer that will minimize the risk of recurrence?" You know, we don't want them to have an ischemic event, but we also know long-term that there would be a real risk of anticoagulation. Just reminder to our listeners that there are new procedures, and our cardiology colleagues are always doing new trials and new devices, and so we should really leverage their expertise here. I am in the final minutes gonna just switch gears a little bit from talking about sort of the nitty-gritty of secondary ischemic prevention and secondary hemorrhagic stroke prevention and thinking about there has been this degree of pessimism around ICH patients, and that, you know, they have a much more severe outcome than our patients with ischemic strokes. I think that that is probably a myth that we need to do some debunking around, and I think maybe we need to reframe in terms of thinking about just the trajectory. So, Dr. Shah, walk us through a little bit about what we can expect about the recovery trajectory in ICH compared to those patients who have an ischemic stroke. Dr Shah: Yes. From some newer data and studies, it is becoming clear that recovery after ICH is much slower than we expect. In general, for ischemic stroke, recovery is measured within the first few weeks to up to 90 days. But in ICH, we now know that patients can keep recovering all the way up to six months and even beyond. In general, from just a, a study of heart recovery that occurs after ischemic stroke, there's a steep recovery in the first seven days, and then sort of after that, patients still continue to recover, but it, it starts plateauing where up to 90 days. Whereas with ICH, there is not much recovery in the first 7 to 30 days, but after that, there is a recovery that occurs significantly between day 30 and day 180, and then some patients continue to recover all the way up to one year. The more severe the hemorrhage, the slower the recovery, but there's still some evidence to suggest that even severe hemorrhage patients can recover all the way up to one year out and beyond. This is, of course, in terms of functional recovery.  Dr Albin: I think that's a really important point for our audience. Many of the listeners are residents, they're fellows, they're seeing these patients in the hospital, and they may not see a whole lot of improvement over even 30 days. But to keep in mind that just because the patient has not had a dramatic recovery within that first month that they may be in the ICU and then on the floor does not mean that that patient will never have recovery, and that we reset our expectations that recovery is possible, it's just gonna be slower. And I think that that's not only important for the healthcare team to take in mind, but also for patients and their families to know there is hope here. It's just gonna be slower. Dr. Ziai, looking ahead, what developments in this are you most excited about that you think will move the needle for care for the long-term outcomes and the prevention for these patients? What's ahead in, in ICH?  Dr Ziai: Yeah, I think the research that's going on is very exciting at the moment. We just saw the presentation at the World Stroke Organization conference in the fall of the TRIDENT trial, Triple therapy prevention of Recurrent intracerebral Disease events, meaning strokes. And these investigators found that a single pill, a fixed dose of three blood pressure-lowering agents actually was successful in significantly reducing the risk of recurrent stroke in patients who have had a history of ICH and have just normal or low-grade hypertension. So rather than having patients on multiple antihypertensive agents, it may be possible to have them on a single pill, and may dramatically reduce their stroke risk. So that's exciting. There is also a trial ongoing, ASPIRING, testing whether antiplatelet monotherapy after 24 hours only can reduce the risk of all serious vascular events in ICH survivors. So very early antiplatelets. The SATURN trial, we didn't talk about statins yet, but it is comparing continuation versus discontinuation of statin therapy in ICH patients. And then we have ongoing epidemiological studies that are really needed to understand this interaction between the cardiovascular prevention strategies, the antithrombotic use, the blood pressure targets, and these high-risk neuroimaging markers for ICH. And I think that's gonna be key, personalizing the interventions for these patients.  Dr Albin: So, I love that. And what I'm hearing is that it's really important to think about the personalized approach as well as how do we simplify things. We know that blood pressure control is critically important to the primary and secondary prevention of ICH, but we have to make it easy for patients to do so. Dr. Shah, I want to end with kind of understanding, you know, this was an unusual topic for neurointensivists to talk about. This was really about prevention. It was about long-term survivorship. It was about not what's happening in the neuro ICU. How did you guys get interested in sort of that aspect of care?  Dr Shah: Yeah, so that's a great question. Dr. Ziai has been my mentor since I was in fellowship, so now about eight years that I've been working with her, and this was a project that I started in fellowship with under her mentorship, looking at long-term recovery in ICH patients, and specifically severe patients. Happy that work has received a lot of recognition. It was published in JAMA Neurology. We looked at patients with severe intracerebral and intraventricular hemorrhage, those that survived with an mRS of four and five at day 30, and what happened to them over the course of the year. There was really not much data on recovery after ICH. And we were very surprised to see that up to 40% of patients that were an mRS of four and five, so really, really severely disabled at day 30, recovered to an mRS of zero to three by one year. About one-third of that group that recovered actually achieved functional independence with an mRS of zero to two, which was very surprising, really breaking the myths around the pessimism with ICH. We found that a lot of the baseline comorbidities like diabetes, white matter disease, as well as what happens to them during the acute hospitalization, were adding all of that information to the severity of the hemorrhage significantly improved our ability to predict long-term recovery after ICH. And so that's kind of how we got interested in this work, looking at how factors in the care that we provide in the ICU, as well as what the patients come in with, how all of that could be modified to promote recovery in these patients that are often been forgotten.  Dr Albin: I think that there's one takeaway to our listeners is that this is really a place where there's a lot of hope for recovery, and that the nihilism that has really surrounded ICH is a thing of the past, and we have to move forward with thinking about how do we proactively impact the recovery and counsel the patients and give them hope. Because just as your research shows, there really is the ability that they can attain that functional independence, which is absolutely astounding. It's really amazing. Again, today I've been interviewing Dr. Wendy Ziai and Dr. Vishank Shah about their article on intracerebral hemorrhage.

This article appears in the June 2026 Continuum issue on cerebrovascular disease. Welcome to the podcast, Dr. Field, and could you please introduce yourself to our audience?  Dr Field: Well, thanks so much. It's a pleasure to, uh, be speaking to you. I'm a stroke neurologist, and I treat adults generally. My wonderful colleague, Thivya Selvanathan, who's a neonatal neurologist, co-wrote the chapter with me. We do, unfortunately, have to treat some children with stroke collaboratively and I do advise on those cases. My practice is about one-quarter clinical, so I treat patients with acute stroke, look after them on the wards, see patients in stroke prevention clinic, and the rest of my time is mainly research and some administrative work and teaching. I run the clinical trials program for the Vancouver Stroke Program, and I do research of my own, mainly focused on stroke in younger adults. We previously did a trial and registry on cerebral venous thrombosis, and more recently, I've been running a national study looking at brain health in adults and children with congenital heart disease.  Dr Berkowitz: Fantastic. Wow, that is a lot that you do, and we'll look forward to the results of some of those studies. So, when adults suffer a stroke, they typically present with sudden onset focal neurologic deficits, very common scenario we're consulted on.  And one thing you and your colleague talk about in the article is that strokes can present differently in infants and in young children. Can you talk a little bit about the differing clinical presentations of stroke in the youngest young as compared to our usual experience treating the older adults?  Dr Field: Sure. So, you know, speaking about this as someone who doesn't see the children directly but has had the opportunity to discuss these patients with my colleagues and, like we all do, learn about it during our training, I think one of the distinctions, especially with neonates, is that it's generally not a presentation with focal neurologic deficits. Often these babies will have seizures or encephalopathy as their main presentation, and sometimes we're only finding out after the fact if they're presenting with developmental delay or early preference for handedness and hypotonia, things like that. So, in very young children, that's a distinction. And in older children, there can be sudden onset deficits and, and unfortunately, sometimes these are mistaken for other conditions that are more common in children, like seizures. But sometimes you can have a more indolent course, say, with something like a focal cerebral arteriopathy or something like that. So, it depends on the scenario, but the big difference primarily is in neonates, as far as I understand.  Dr Berkowitz: Perfect. That's very helpful. So as an adult neurologist, when I think about causes of stroke or teach sort of the categories of causes of stroke to our residents and students, when we think about the evaluation of stroke, I divide them broadly into causes related to the heart, causes related to the blood vessels, and causes related to the blood with, in the adult world, the most common things, of course, being atrial fibrillation for the heart, atherosclerosis for the blood vessels, and then risk factors for atherosclerosis in the blood, diabetes, hyperlipidemia, very rarely picking up a hypercoagulable disorder in the blood column. And reading your article, it seems that, correct me if I'm wrong, stroke in young adults, stroke in the pediatric population can basically be organized into those same broad categories, heart, blood vessels, and blood, just that there's many more conditions on the differential diagnosis that you would consider in young adults to begin with and then children and then neonates as we get into the younger and younger population. So, I'd like to talk about each of these sort of buckets of etiology in turn and ask you about some of the causes we would consider in young adults and children in each of these, and then as they come up, probably ask you more questions about how frequently we find these sorts of things, how frequently they're the cause of stroke treatment, et cetera. So, let's start with the heart. As I said, in adults, we're mostly looking for rhythm disorders, right, atrial fibrillation. Sometimes we'll pick up a patent foramen ovale or PFO or other structural abnormalities, but mostly we're thinking about atrial fibrillation. But reading your paper, I was struck by the huge variety of conditions that you might be looking for in the heart in children or infants with stroke. So, can you tell us a little more about cardiac etiologies of stroke in the young?  Dr Field: Yeah. So, I'd say unlike in older adults, where it tends more often to be a rhythm disorder, in children and adults who are younger, it's primarily a structural cause, and congenital heart disease being the most common. And it changes a little bit from younger adults shifting downwards in age to younger children in terms of the fact that often if we're seeing an adult with stroke related to congenital heart disease, it can be a paradoxical embolism from a previously undiagnosed PFO. Not in all cases, but fortunately this is improving over time. You know, generally people with diagnoses of more severe congenital heart disease are followed up from childhood and people are aware of the diagnosis, and hopefully they're being managed and watched for things like premature arrhythmias or depressed heart function or other things that can develop and require their own distinct antithrombotic management, for example. In young children, however, more severe causes of congenital heart disease tend to more frequently be associated with stroke. And in many cases, those strokes can be early on in life or associated, say, with perioperative complications or other iatrogenic-related causes in, in that way. Again, congenital heart disease can be associated with stroke at, at any point in the life course. But as adult neurologists, most frequently we're seeing very simple lesions like PFO with large shunts, and in children, it tends to be the more complex causes of congenital heart disease.  Dr Berkowitz: Got it. So, let's move on to the blood vessels. Again, in adults, we're usually thinking about atherosclerotic disease, be that of the cervical arteries or of the intracranial arteries. But in your paper, a lot of discussion about the various vasculopathies, arteriopathies that can be cause of stroke in younger adults and in children. Could you talk a little bit more about some of the vasculopathies and vascular conditions that are causes of stroke in the younger population?  Dr Field: Sure. Before I do that, I will say that especially in older younger adults, particularly over the age of thirty-five, and you know, kind of makes me shudder that that's an older younger adult. But, um, in, in any case, certainly conventional vascular risk factors are more common in this population with stroke, especially in those who don't have PFO-associated stroke. Like conventional atherosclerosis, you know, certainly is a cause of stroke in younger adults. But that being said, certainly other vascular causes and vasculopathy in particular is a much more common cause of stroke in younger adults and, and children than it is in older adults. In particular, dissection is an extremely common cause of stroke in younger adults. Generally cervical artery dissection from non-inflammatory vasculopathy, usually on, sometimes on the FMD fibromuscular dysplasia spectrum and, and sometimes, you know, provoked by minor trauma or something post-infectious that may make the vessels a little bit more susceptible. And in younger children, this inflammatory focal cerebral arteriopathy is a distinct cause that is a common cause of stroke in, in young children. There are other causes that can affect the blood vessels, you know, rarer things like vasculitis and vasculopathies that can develop in the context, say, of sickle cell anemia. But in general, as a bucket, vessels are still very important, but the pathology tends to shift.  Dr Berkowitz: Got it. And you, um, alluded to a point that I wanted to ask you about. You mentioned the sort of, there's stroke in the young, and then where do you draw the line at young? Less than sixty, less than thirty-five, and then we've also talked about strokes as young as before the age of birth. Yeah, I'm remembering, is it the Helsinki study, one of the early large series of stroke in younger individuals? I think that, was it eighteen to forty-nine in that or fifty-nine? I don't remember the exact age, but being struck reading that paper as a resident and thinking about the workup for exotic causes we do, right, and when a young patient has a stroke. And correct me if I'm wrong, the most common etiologies of stroke in that series, and I'm curious the other large series yourself have been involved with, have still been vascular risk factors and arrhythmias and things that we, even common, quote unquote, common things in the young, such as dissection or hypercoagulable states. Uh, the things that we sort of tend to think about first are actually less common. But acknowledging that that paper has folks up to the late forties when the vascular risk factors may be, um, unfortunately kicking in earlier, uh, and earlier due to dietary and lifestyle factors. So is that true, or do you have sort of an age cutoff when it's, we say stroke in the young, people sort of think, "Oh, they'd work someone up differently if they're less than sixty, and they have no vascular risk factors or few vascular risk factors." When do we start getting into the kind of younger population where atherosclerosis and cardiac arrhythmias are not number one and two?  Dr Field: I'd say first of all, you and I must have trained around the same time because I was also in my training, really struck by the results of the Helsinki study going, "Wow, I, I really didn't know how much of a role these conventional vascular risk factors still play." And I think we're seeing that information reiterated, unfortunately, like even with higher prevalences and more attributable risk in some of the newer series. There are newer European series looking at stroke in younger adults, and more recently, there's been one that we mentioned in the article from the Florida Stroke Registry. And it's true that generally the burden is in the older younger adults. But what I would say overall in terms of kind of how things guide the workup, you need to look at the patient and consider things. I mean, obviously you don't want to miss things that can be treated differently and identified by tests easily. You know, things like ruling out syphilis or antiphospholipid antibody disease in, in younger patients. You really want to make sure that that's not something that, that you'd miss because, you know, obviously your treatment is going to change. However, certainly we start with the basics for stroke workup in any patient that's coming in. At my center, CT angiography. Some centers it may be MR angiography and echocardiography. We take a careful history. We look at the blood work. We look at the vascular risk factor burden. We find out if there's kind of any worrisome personal history, family history, look at their general health context. I think that really helps to guide how far we go in a particular workup, and it also helps to direct the other investigations and types of follow-up we need to do. For example, if a patient has a fairly suspicious story for dissection, let's say they're getting over a cold, and they went to the gym, and, you know, there was a sudden movement that they did that really produced headache and neck pain, and there's an obvious cervical artery dissection. I'm not going to go too far down testing them for rare infections and doing advanced cardiac imaging unless something shows up on their initial echo, for example. But I will make an effort to do more detailed vascular imaging of the rest of their body, find out careful family history. If there's additional manifestations of a non-inflammatory vasculopathy elsewhere, say consider sending them to medical genetics, or obviously, if this is, you know, a second event, your flags raise even more. So, it really depends on the patient. If I find out that there's, you know, a family history of premature cardiac disease and things like that, you know, obviously we're gonna be keeping a close eye on their cholesterol, making sure that we're not identifying, for example, familial hypercholesterolemia, which is, you know, something that comes up not infrequently where we'll see an LDL in an untreated patient of more than five. I apologize, you're gonna have to do the conversion to American units on that. But there are things we identify and, you know, again, you don't want to fall solely on heuristics and your preconceived notion of, of the patient. You do have to consider the results of the investigations that you do order. But I think you can certainly be mindful in terms of how you direct your workup and in turn, how you direct your follow-up.  Dr Berkowitz: That's great to hear your approach. Yeah, as you said, our approach always begins with the same, coming back to these three categories, right? Doing some type of structural imaging of the heart, rhythm monitoring for the heart, and then vascular imaging of the head and neck. And then I was going to ask you, and you sort of began to answer this question. Yeah. What's next and how far do you go? I think most people think the expanded stroke workup in the young is at a minimum, a TEE if there's been no signal thus far on the original workup. I just mentioned and you spoke about, and then probably hypercoagulable testing and only sending arterial side if there's no shunt and venous and arterial side if there's a shunt. Is that your second pass approach or did I miss anything, or are there other nuances there that are helpful to discuss?  Dr Field: No, I think that's generally in keeping with what I do. I think with TEE being very important. I mean, the first pass are arterial stuff. Really, it's antiphospholipid antibodies and, and making sure there's no cancer. Like you said, only if there's a shunt do I pursue other venous hypercoagulability testing. Again, you [chuckles] kind of reiterate, go through with the history, make sure there's kind of no red flags. And sometimes, obviously, you do your best reasonable job with the first pass workup, and you will find out when someone presents with a second event that it's something very unexpected. Maybe first manifestation, someone with no obvious history and very initially normal-looking imaging, say with, with CATASL or something like Fabry's disease or something where you would consider it if there was kind of a more classical picture. But it wouldn't be something you would do kind of on your first or even second pass workup in the absence of any sort of clinical suspicion, family history, or something along those lines.  Dr Berkowitz: I'm curious just as far as rough percentage. I feel like many of these patients we see it's a patient who's young and who's had a stroke, and the initial first pass has been unremarkable, and we do our TEE, and we do our hypercoagulable workup. Again, antiphospholipid antibodies only if it's-- there's no shunt. And if there's a shunt, adding on some of the venous hypercoagulability protein C, protein S, factor five, Leiden, et cetera. A lot of the times I feel like we don't find anything. What's your sort of general gestalt? Again, as a general neurologist who does a lot of inpatient neurology, I feel like when these cases come up, it's not that common that you say, "Oh, I actually diagnosed protein S deficiency." Or every once in a while, diagnose an antiphospholipid antibody, or you'll find a PFO on TEE. You didn't find on TT. I've maybe found one fibroelastoma in many years. How often do you find something? How often is it just as an adult a cryptogenic stroke in a young adult or child?  Dr Field: So much of what we see is PFO-related, dissection-related, conventional vascular risk factor-related. We do send referrals to medical genetics. Sometimes we'll do testing for rare things like Fabry's or consider other diagnoses. But I mean, those tend to be the exceptions. About one in four to one in five young adults with stroke end up with this cryptogenic label. I like to keep them on my radar for a few reasons. I think, one, it produces tremendous anxiety for them to not have a cause of stroke identified and just to kind of have a generic approach to secondary prevention. So, I think just to kind of keep an eye on them, manage their anxieties each year, make sure there's kind of no updates in, in terms of general secondary preventionAnd sometimes just things dawn on you later or there are new conditions, say things like, you know, DADA2, this, you know, adenosine deaminase deficiency. You know, there are new diagnoses that, that come on the radar. And sometimes treatments change. You know, for example, when I was starting my early career, the evidence hadn't yet been in place for PFO closure, and then all of a sudden, the paradigm completely changed. And you want to make sure that you can get in touch with those patients to reconsider your approach at the time. So I realize that not everybody has the luxury of extended follow-up with their patients, but I think often you can kind of encourage them or their healthcare team or just, you know, patient themselves to keep in touch periodically just to make sure that there haven't been any changes in treatment paradigms or just with your own awareness of particular, you know, diagnoses or, or just kind of readdressing the situation, uh, a year after and seeing if there's anything that may have occurred to you in the interim.  Dr Berkowitz: Perfect. Really illuminating to hear your approach to these challenging cases. And as you said here and then a couple of times, I think, in this interview is in many of these cases it's your first pass, maybe even your second pass, you haven't found anything. And the key is, unfortunately, as distressing as it may be for the patient as well as for us to not have an answer, to just keep following these patients. And sometimes you really can't sort it out until something else happens, either neurologically or systemically, where you say, "Oh, that's what this was." But there would've been no way to know it from the first presentation. So, we've talked a lot about the diagnosis of causes of stroke in younger adults and children. And in the last minute or two here, I just wanted to talk a little bit about treatment. You mentioned early on that you're involved in thrombectomy cases in children. What's the state of evidence or at least state of practice in terms of offering therapies like thrombolysis and thrombectomy in our patient population? I guess it would be under 18, right, who is not studied in the major trials. Do we have evidence and, or in the absence of evidence, what's sort of the, the expert guidance on treating young adults under 18 and children with some of these acute therapies?  Dr Field: So, trying to keep up with the literature on this. You know, certainly the evidence has been more established in a small trial and pediatric registries for use of tPA, tissue plasminogen activator, in children just because, you know, it's been around much longer. In terms of tenecteplase, which I, I really think signifies a, a practice shift in adult stroke because of its, you know, non-inferior efficacy and ease of use and potentially better rates of recanalization over time. In children, to my knowledge, that evidence base is, is limited to case series and anecdotal shifts in availability of drug and, and different practices. So, the evidence base is not particularly strong for tenecteplase in children who are identified within a reasonable amount of time who are still otherwise candidates for thrombolysis, you know, thrombolysis in children. Children who are a little bit older, I think, can't remember the exact age, but generally very young, like neonates, children who are under the age of two, I believe. I would want to double-check that thrombolysis is less commonly used and just because the safety has not really been that well-established. And for thrombectomy, it's now recommended to use thrombectomy in otherwise eligible children in the newest AHA guidelines. It gets a little bit more controversial in very young children. Under the age of six, there's less of an evidence base and, and often it will depend on people's level of comfort in terms of the size of the arteries. It's my understanding that once you get to about age six, the artery diameter is similar to that in fully grown people. But in younger children, I think just because of the catheters, there can be risk of, of injury. So, it's more of a case-by-case conversation with your interventionalist for younger children. And again, the evidence to intervene is not there for very, very young babies, for example.  Dr Berkowitz: That's very helpful to hear the current state of the evidence and the current state of practice, acknowledging, of course, there's not that much evidence, and these are relatively uncommon occurrences, fortunately, for children, but making it challenging for practitioners and practices may, um, vary based on different institutional protocols.

This is Dr. Casey Albin. Today, I'm interviewing Dr. Christopher Leon-Guerrero about his article on Thrombolysis, Thrombectomy, and Antithrombotic Therapy for Acute Ischemic Stroke. This article appears in the April 2026 Continuum issue on cerebrovascular disease. Welcome to the podcast. I always like to start by just having you introduce yourself so our listeners know a little bit about you.  Dr Leon-Guerrero: Thanks for the introduction, Dr. Albin. Really glad to be here today. My name is Chris Leon-Guerrero. I'm a vascular neurologist at Atrium Health in Charlotte, North Carolina, at Carolinas Medical Center. I'm an associate professor in the Department of Neurology. I serve as our Neurology Residency Program Director, and I also wear the hat of an outpatient stroke director in our clinics.  Dr Albin: So, you are wearing a lot of hats and balancing a lot of things, and it's a really exciting time to be talking about this. For our listeners, we are recording this right after the launch of the American Heart Association, American Stroke Association just released their new guidelines on acute ischemic care. So, no better time to kind of dive into some of this. And really, when I think about acute ischemic stroke care, it's dramatically transformed in the last two to three decades. I mean, from lengthening time windows for IV thrombolysis to expanded thrombectomy eligibility, this is really, I think, some of the most exciting stuff in neurology. And your article did a fantastic job of distilling those rapid advancements and clarifying some of the evidence behind some of these new evolving treatment selections and imaging modalities, and it's exciting. So, let's just start with thrombolysis. Where are we now with IV thrombolytics and the time windows there?  Dr Leon-Guerrero: So, a lot has changed in the last decade, since that initial trial with NINDS, nearly thirty years ago. We're still giving intravenous thrombolysis in the traditional time window up to 4.5 hours, and really emphasizing we should be selecting patients for treatment early and quickly as possible. In most of those cases, a non-con head CT is sufficient to rule out bleeding and initiate treatment as quickly as possible. Where things have gotten really exciting is using advanced neuroimaging to help select patients beyond that traditional 4.5 hour window, and we're able to treat patients even up to twenty-four hours from symptom onset.  Dr Albin: Which is really exciting. It has really totally shifted the paradigm here. You know, I think most listeners are going to be pretty familiar with three to four and a half hours. Like, that's sort of our standard. What can you tell us about some of the advanced imaging we're using for that later selection period?  Dr Leon-Guerrero: It's around the principle of you want to be able to, uh, rescue significant salvageable tissue without a lot of core. So, this large profusion deficit and small core is really how you're trying to select out these patients. And two types of modalities are used. One is going to be MRI, and a lot of those imaging protocols, you know, are outlined in the WAKE UP trial and basically are looking for patients with DWI hyperintense lesions and FLAIR negative lesions to suggest that patients in an early time window that's treatable for thrombolysis. And then in the other category, we'll be using profusion imaging, whether that's CT profusion or MR profusion, to look for patients with large salvageable tissue.  Dr Albin: Yeah. And I think that this has been one of the things that, to me, has been really impactful is I think when WAKE UP came out, it was exciting. It was fun to sort of think about, "Hey, we're going to be able to use MRI." But MRI can be very challenging to get acutely, especially in community centers where they don't have the capabilities to get someone from the emergency department into an MRI rapidly enough to make thrombolysis decisions. So, to see some of that expand to CT profusion has been really exciting. How are you going about sort of counseling patients or thinking about their risk when you're using some of those, like, advanced imaging techniques?  Dr Leon-Guerrero: Yeah. I think it's similar to the conversations we've had with patients even within the traditional 4.5 hour window. The risk for intravenous thrombolysis is hemorrhage, and counseling patients on the, you know, the risk and benefits of hemorrhage and the potential clinical benefit of receiving thrombolytics is important. And then providing patients with that information to make an informed decision, so that they can make the best decision for their own care.  Dr Albin: Totally. And it's, again, time sensitive, but trying to give families enough information and enough time to sort of process those, especially when it's a little bit beyond the standard that we're so used to consenting for. The other big area that's really changed is that tenecteplase has become the star of the show. It's really gained momentum, so what should clinicians understand about this?  Dr Leon-Guerrero: Yeah. There's been an explosion of data over the last decade on tenecteplase supporting its use for clinical practice. You know, there was recent updates even from the neurology journal with a large meta-analysis with all of the data showing good clinical outcomes and perhaps even lower risk of bleeding. And so, I think you're seeing a lot of centers across the country switching from alteplase to tenecteplase. There's some practical advantages. So tenecteplase is a one-time bolus dose. And then biologically, it seems to have better fibrin specificity, longer half-life, which may ultimately make it a more attractive drug and may make it even more effective. But I think the practical aspects of tenecteplase are not to be understated. I think there's a lot of advantages for speed and efficiency and for centers to make that switch.  Dr Albin: Yeah. I remember when our health system made the pivot from alteplase to tenecteplase. Like any changes, that obviously created some adjustments with the new workflow. But, the fact that this could be given just as a one-time dose and not with the "we got to calculate the bolus, and now we got to get the infusion on board," like really simplified workflow. So, I think that's been pragmatically one of the nicest things we've done in stroke care. Really exciting.  Dr Leon-Guerrero: Yeah. And, you know, it's a doable thing. I think you have to be, very deliberate about it at whatever center you're at to make sure that all stakeholders are aware of that change. I think that's helpful to get everybody involved and have a lot of planning to avoid wrong dosing errors or inadvertently dosing as alteplase versus tenecteplase. But it's certainly doable, and I think in the long term, centers that have switched have been pretty satisfied with tenecteplase.  Dr Albin: And you know, initially when this came out, there really was sort of a debate about, is it gonna be 0.25? Was it gonna be 0.4? Where have we landed with that debate?  Dr Leon-Guerrero: So, I think we found the correct dose is 0.25 milligrams per kilogram is the recommended dose with a max out of 25 milligrams. There's some within the American Heart Association guidelines that were just published. They mentioned even tier dosing based on 10 kilograms, so intervals. So, that may be an easier way for centers to do it. But that cap out dose of 25 milligrams at 0.25 milligrams per kilogram, I think, is the sweet spot.  Dr Albin: Yeah. That's great, and I think that that has helped, you know, say, "This is what we're doing. There's not a debate that's happening anymore." And that really just got codified in the new ASA guidelines, so really exciting there. So, there is a lot of guidance for these patients, but I think one of the things that your article really tackled is the fact that there are some special populations, where we really still don't have a lot of guidance. And so, I think just to kind of distill those for the listeners, thinking about our pregnant patients, thinking about children, how are we approaching thrombolysis decisions in these special populations?  Dr Leon-Guerrero: These are always tough cases. For example, for pregnant women, they've often been excluded in the thrombolytic trials. But there's still evidence. You know, there's some inference based on the evidence we do have, and there's a lot of registry and case reports suggesting potential safe treatment for pregnant women. And I think when you're approaching those cases, again, it's gonna be patient-centered and really should be multidisciplinary. These are the types of cases you really need to lean on your maternal fetal medicine colleagues, your high-risk OBGYNs, your obstetricians to help with that decision-making. And I think, a multidisciplinary approach is the way to go for these cases. It's the same thing with the pediatric population. We had some data. There was one trial, randomized control trial, called TIPS trial that looked at using intravenous alteplase for acute ischemic stroke in patients under the age of 18. It had difficulty with enrollment. But I think most experts would argue that patients with pediatric stroke should be considered for intravenous thrombolysis if appropriate. Again, same thing. You want to make it a multidisciplinary approach, really getting your pediatric neurologists, your pediatricians involved early to make the best decision for the patient.  Dr Albin: Yeah. That's just really an important takeaway, just thinking about this as a multidisciplinary decision, because there are going to be other stakeholders to the patient's care who may have some different information than what we as neurologists are bringing to the approach. And obviously, our perspective really matters. But trying to work in everyone's unique vantage point of the patient really helps to make the most effective decision. When we talk about acute ischemic stroke care, I really don't think that you could do justice to the topic without pivoting to mechanical thrombectomy, which, you know, as we think about how the medical field as a whole, not just neurology, how the medical field has evolved. I mean, there's probably no bigger impact than mechanical thrombectomy has made in terms of reducing not just morbidity, but mortality from stroke. I mean both. So, thrombectomy has been around for a while, but just walk our listeners through what's the core that we for sure know that these are the patients that this works for?  Dr Leon-Guerrero: The types of patients we should be selecting for intervention are patients with large vessel occlusions. And those initial trials that were published in 2015 really demonstrated that this is a quite an effective treatment for patients with large vessel occlusion ischemic strokes in the anterior circulation. When that smattering of publications occurred in 2015, the general consensus, we should be treating all patients up to six hours from symptom onset if they do have a large vessel occlusion. And then, Dr. Albin, as you know, the, the windows continue to expand. So, we were using advanced neuroimaging with MR selection and perfusion selection based on DAWN and DEFUSE 3 trial protocols to select patients all the way out to the 24 window, and it's even expanded beyond that over the last few years.  Dr Albin: I think that when we think about trials that really, totally, changed the game, when we think about DAWN and DEFUSE 3, and we switched from that time-based window to more of that, like we talked about for thrombolysis, that tissue-based clock and, like, looking at what is salvageable and where can we make an impact on salvageable tissue, truly moved the needle in terms of just bringing this therapy for people who, you know, it's hard to get in within six hours. When we moved the needle to 24, it made a huge difference. But people were still coming in with a lot of ischemic damage already done, and they would have traditionally been excluded from being enrolled in thrombectomy trials. But that's changing too. So where are we there?  Dr Leon-Guerrero: Yeah. I think there were lessons learned from DEFUSE and DAWN that we were probably over-selecting. Perhaps too stringent. You know, we had number needed to treat in the range of two to three for good outcome based on those trials. And so, I think those were lessons learned to move forward, and we, and, and people started looking at large core infarctions. And in the last few years, we've seen a multitude of randomized control trials examining large core infarctions. These are patients with ASPECT scores all the way down to zeros. A lot of the trials relied on three to six as their score, but there was at least one large core study that looked at ASPECT scores down to zero to two, and all of these studies showing benefit.  Dr Albin: Yeah. And we've really moved into if there's some tissue to spare there, probably getting clot out really makes a big difference in impact. You know, it was really surprising to me as a neurointensivist looking at these trials, that the trials had such low rates of hemorrhage, and pretty low rates of dramatic cerebral edema after thrombectomy. I don't know that we've seen all of that in sort of real world applications, but again, we are still seeing some of these patients come in, that really would've been devastated having some amount of functional recovery regained, which is incredible. In terms of another patient population that I think gives a lot of people pause or stickiness, is those basilar artery occlusions, right? Another large vessel, but one that we've had a little bit harder of a time enrolling in trials and having well-selected trials. Where are we now on whether or not basilar artery occlusion should go to mechanical thrombectomy?  Dr Leon-Guerrero: So, a lot of excitement in this area, too. There's at least two studies that were published in the last five years that were showing benefit in doing thrombectomy for patients with basilar artery occlusion up to 24 hours, and these were patients with moderate to severe deficits with NIH Stroke Scale scores greater than 10. And then making sure that they don't have large core, so using a newer scoring algorithm on the CAT scan called PC ASPECT, so basically a posterior circulation ASPECT score, to kind of make sure that patients don't have large core infarctions that are being considered for thrombectomy. All of those things collectively in those two recent studies, the ATTENTION trial and the BAOCHI trial, I think is what ended up making those studies positive, is that we were selecting the right types of patients, uh, without large core, early core, and patients with moderate to severe deficits that made the difference from previous trials.  Dr Albin: Yeah. I think that that's so important. Those trials to me, and like how long it took to get those enrolled, really emphasized to me that there really was a selection bias. Like, we believed this worked, which made it hard to then do a trial. But I'm so glad to hear that we have the data now to support moving forward in a more rigorous way.  Dr Leon-Guerrero: You're absolutely right. I think that was some of the challenges with the initial trials. In fact, the authors had commented on that. There's a lot of difficulties with lack of clinical equipoise, or experts wanting to take these patients anyways out of clinical trial and treat them, and so that's always been an issue. And then, you know, we all remember basilar artery occlusion cases. They can be severe, devastating cases in our career, but the reality is they're not that common. So, if you look at large vessel occlusions, they only account for about 10%, and if you look at all stroke patients presenting to most centers, they represent about 1% of cases. So really hard clinical trials to do just because there's thankfully not a lot of patients walking around with basilar artery occlusions, but certainly makes for challenges when you're trying to conduct randomized controlled trials on this subset of patients.  Dr Albin: Absolutely. But we did it, and I think that, like, really if, if the listeners take nothing else, it's that the field of vascular neurology is really moving forward with evidence-based, doing very rigorously controlled clinical trials, which is, I think, is what makes this field so exciting. Finally, closing out, cause we could talk all day, but we don't have all day. You know, it seems to me that more and more we are just using dual antiplatelet therapy all the time. And maybe that is, uh, a little bit of a hyperbole, cause I don't think it's all the time, but let's walk through— when is there good evidence for dual antiplatelet therapy?  Dr Leon-Guerrero: Yeah. So, there's strong evidence for early initiation of dual antiplatelet therapy or DAPT in patients with minor stroke or high-risk TIAs, and it's been studied using both clopidogrel as an add-on to aspirin and ticagrelor. Both seem like they're viable options in patients. I think one of the key things is the duration of therapy. So, in these cases with minor stroke and high-risk TIAs, we really should be confining the treatment of early DAPT for 21 days. The risk profile changes, so the risk of recurrent stroke starts to decline with time, and that risk of hemorrhage complications increases with time. And so that sweet spot of 21 days, or even some centers will do 30 days for just practical purposes, you know, really is what we should be doing in most of those cases. Other instances where DAPT can be considered, is in patients with intracranial atherosclerosis that's symptomatic, extrapolating from the SAMMPRIS trial that in the, in the medical management arm alone, used dual antiplatelet therapy with aspirin and clopidogrel for up to 90 days. So, you'll see that as well in clinical practice. Some people will opt for a 90-day duration for those patients with symptomatic intracranial atherosclerosis and stroke.  Dr Albin: Just so I emphasize, this is not set it and forget it. You can stay on DAPT forever. It is you're going to have a definitive time course, 21 days, 90 days. We have directed instructions where we're doing more benefit than harm because of that risk of hemorrhage.  Dr Leon-Guerrero: That's correct. In most cases, we really should be confining the duration of DAPT either to 21 days or 90 days. This is a challenging clinical practice. Centers really have been making an emphasis on stroke follow-up, so making sure these patients get appropriate and timely stroke follow-up to address these issues and to make sure that DAPT is discontinued if appropriate.  Dr Albin: Yeah. I love that, and I want to pull on that a little bit because you as someone who is helping direct a stroke center– A lot of this really does rely on systems of care. When we think about early lysis decisions or mechanical thrombectomy, it's how do we get the patient to one of those capable centers as quickly as possible? And then on the back end, when you're discharging a patient, how do you make sure that they are getting follow-up, making sure that they're getting their Holter monitor if they need it? You know, all the stuff that goes into kind of figuring out, why did the stroke happen? What are some of the things that you, in your role, are really excited about, that will move the needle over the next five or 10 years?  Dr Leon-Guerrero: Yeah. I think a lot of centers are doing it just like we're doing it. It really has to be a team-based approach, and you really want to reach the patient where they are in terms of the continuum of care. And so making sure if it's the in the field that you've reached out to your EMS and first responders to make sure they understand triage protocols to get patients where they need to be, to get the acute treatments that they need for the type of stroke that they're presenting with, to the actual centers that you work at, making sure your whole team, nurses, emergency physicians, APPs that are involved in care are all aware of the stroke protocols and how we're selecting these patients, making sure that your imaging protocols are up to date, and so that it's seamless when patients come in, that we're not adding on perfusion if we should have gotten that up front– We already know, have made decisions before that patient gets there. And then thinking about the patient after that hospital stay, I think, is critical. We really want to reduce their risk of recurrence, making sure that we're leveraging transitions of care, getting those patients seen in our stroke clinics for follow-up, and then make sure we're passing that baton to the long term. All of their long-term comorbidities that may be increasing their risk of stroke are managed and reduced as best as possible.  Dr Albin: From the Continuum journal to the continuum of stroke care.  Dr Leon-Guerrero: That's right.  Dr Albin: I mean, we have it all. I think that that really is so important. I'll just close with what's one thing that is your favorite part about being a vascular neurologist?  Dr Leon-Guerrero: I think it's what attracted to me to this field. As a medical student at that time, all we had was intravenous thrombolysis, and there was so much promise. There was so much promise that there was going to be widespread advancements in acute stroke, and here we are. There's been a tremendous amount of advancements and improvements for patients. I'm really excited to see what unfolds in the next few years, and I'm really excited that we've been able to increase the number of patients we're able to treat with acute ischemic stroke. I hope that we continue to expand the time window, the inclusion criteria, all of those things that we can treat more stroke patients effectively.  Dr Albin: It is really a very exciting time to be a vascular neurologist.

Thank you for listening to Continuum Audio.

Today, I'm interviewing Dr. Mitchell Elkind about his article on stroke prevention. This article appears in the June 2026 Continuum issue on cerebrovascular disease. Welcome to the podcast, and please introduce yourself to the audience.  Dr Elkind: Thank you so much, Katie. So, my name is Mitch Elkind, and I'm the Chief Science Officer for Brain Health and Stroke at the American Heart Association and a stroke neurologist by background.  Dr Grouse: Well, I just want to start by saying that I really enjoyed reading this article. I think this is just a really wonderful article I recommend strongly. Such a high yield, an important topic for a lot of us who see patients who are interested in learning about their stroke risks or need help with, uh, stroke prevention after having a stroke. So, I wanted to start. What's changed in the last couple of years? You know, what are some big highlights that you really want to stress that are different from maybe the last time we reviewed this topic?  Dr Elkind: Sure. Well, there's been a lot of development in the field of secondary stroke prevention, for one thing. But even beyond that, I think we increasingly appreciate how important it is to control what we call the social drivers of health on the earlier side, primordial or primary prevention. And that has been a big advance, I'd say. And I would also say, I think it's really important for neurologists to understand some of those questions about primordial and primary prevention. You know, we tend to get involved with patients after they've had a stroke or maybe a TIA, some kind of event. But sometimes we find people who are following for, you know, non-stroke related conditions who have risk factors also. And we can really play an important role in identifying those risk factors and helping to prevent a first stroke or vascular event as well. So, I think it's real important for us to be doctors even before we're neurologists. So, you know, Katie, about ninety percent of stroke risk is modifiable, so we can do a great job as neurologists in preventing stroke. And one of the most important things that we can do is to identify and treat high blood pressure. And recently, actually, the American Heart Association, American College of Cardiology guidelines on the management of hypertension have said that treatment of high blood pressure not only prevents stroke, but it can also help to prevent cognitive decline and dementia. And this is the first time that we've had a class of recommendation one and level of evidence A, the highest level of recommendation we give for the use of blood pressure treatment to prevent dementia. And that's largely based on the results of some large trials that have come out recently showing that you can prevent dementia with blood pressure control. So that's a really exciting link, I think, between cardiovascular risk factor control and subsequent brain health. It just illustrates the role that neurologists can play in, so many conditions outside of stroke as well.  Dr Grouse: That's a really great point, and I want to get a little more into the idea of primordial stroke prevention. Can you tell us a little bit more about what that might be?  Dr Elkind: So primordial prevention refers to addressing how we can prevent risk factors from occurring in the first place, and how can we improve the environments in which people live. You know, we know that only about twenty percent of health outcomes is dependent on what happens between the patient and their doctor in the office. About eighty percent of it is due to what happens in the environments in which we live, work, pray, and play. And so that's what we mean when we refer to the social drivers of health. What is the neighborhood like where somebody lives? Do they have access to healthy food? Do they have places where they can go to exercise? Is there air pollution in the area that may affect their health? You know, one really interesting fact that's become apparent in the last few years is that air pollution is a major risk factor for stroke. Something like a sixth of all strokes can be attributed to the quality of air. And so, what are the things we can do at the broader public policy, community level to reduce the risk of risk factors like high blood pressure and diabetes even before somebody has an event that brings them to the attention of the doctor? So that's what we're thinking about with regard to primordial prevention. It's the earliest stage in prevention.  Dr Grouse: And that's really fascinating. You know, I think an area that we haven't, as neurologists, really put a lot of our time thinking about, but clearly a very important thing. I really appreciated reading your article about how you incorporated the fact that, you know, a lot of these risk factors overlap very, very closely with all the risk factors for various types of cardiovascular events. And I would imagine that the work you've done as the Chief Clinical Science Officer for the American Heart Association has informed a lot of the way you've thought about-Trying to bring all these risks together and think a little bit more holistically about the whole thing. Could you tell us a little bit more about that and the work that you've done on the American Heart Association's Life's Essential 8 score?  Dr Elkind: Sure. I can't take credit for it. It's really work that was done by others at the Heart Association, particularly a cardiologist and epidemiologist named Don Lloyd-Jones. But many other volunteers participated. Life's Essential 8 is our approach to primary stroke prevention and cardiovascular prevention more broadly. We say Life's Essential 8 because it includes four health behaviors and four health factors that people can observe to reduce their risk of cardiovascular disease. The four factors are kind of things like know your numbers, your blood pressure, your blood sugar, your body mass index, right, which is a combination of weight and height, and your cholesterol level. So, know those numbers and keep them within the recommended ranges, and talk to your doctor if they're not. And then four lifestyle behaviors. So, one of them is to eat a healthy diet, and typically that means the Mediterranean diet. It means getting regular exercise, and we recommend 150 minutes a week of moderate to vigorous physical activity. Of course, it means abstinence from smoking or other tobacco products. And the last one, the eighth one, which I was so excited about when we added this, is sleep, recommending at least seven hours of sleep a night. So, I was really excited about this because we used to talk about Life's Simple 7, and then the last iteration of our recommendations included this recommendation for adequate sleep because of the mounting evidence of the importance of sleep to cardiovascular health. But sleep is really a brain function, right? And so, it was really the first, in a way, specific brain function that was added to our recommendations. So that's Life's Essential 8. People can read about it online at heart.org and recommend it to your patients as a simple way for people to understand the best approach to reducing their risk of cardiovascular disease, including stroke.  Dr Grouse: I checked it out myself after reading the article. It's very accessible to patients. It's a great education tool. And they can, you know, see their own score and use that in their own way to, to think about what their risks are and how they can help mitigate and then rescore themselves down the line. There's also, though, on the kind of more the clinician side, the PREVENT calculator as well. Could you tell us a little bit more about how we could use that in approaching this patient population?  Dr Elkind: Yeah. So, I think of Life's Essential 8 as being a patient-focused tool that people can use. PREVENT is really more for clinicians. Anybody can look it up online and enter your data into it. There's a risk calculator online. But the basic idea behind PREVENT and other similar risk calculators is that it's a way to estimate somebody's risk of having a cardiovascular event like stroke or a heart attack or even heart failure by entering information about your health. And we used to think, we used to use something called the ASCVD, atherosclerotic cardiovascular disease risk calculator, or the Framingham score. Framingham Heart Score, for example, was another one. PREVENT is the latest version, and it has several advantages over those earlier types of risk predictors. For one thing, it predicts risk at younger ages as well. It goes down to age 30. It predicts risk over a longer duration of time, so over 30, 10 or 30 years. It eliminates the use of race as an item to put into the calculator and substitutes for that socioeconomic status, so it's not a race base, but a measure of social disadvantage. And it also includes kidney elements, kidney measures. It includes renal function, for example, that weren't included in prior measures, and it can also be used to predict heart failure, which was not part of the original calculators. Another major advantage of the PREVENT study is that it was based on real-world data from about three million patients, many, many more than the 50,000 or so that the earlier risk calculators were based on. So, it has a much more robust data set and therefore allows a bit more precision in the ability to predict future risk of events. And typically, primary care doctors would enter their patient's data, calculate a risk, and then based on the results of the risk calculator, they can make recommendations about what type of medications a person should take or what other strategies they could use to reduce their risk. And so that's the role that PREVENT plays, is really being focused more for the clinician than the patient.  Dr Grouse: Really great tool for us to be aware of. You earlier alluded to the fact that neurologists are in the situation where we sometimes are helping patients with this primary prevention. But you also make a case for why it's in the patient's best interest for us to be involved in, in these conversations when we can, when we have the opportunity. Can you tell us more about that?  Dr Elkind: Shared decision-making is really important because we know that people aren't going to lead the healthiest possible lives if they're not invested in their care. And so, a doctor telling somebody what to do if the patient doesn't want to do it is gonna have limited benefit.So we emphasize the importance of shared decision-making as much as possible. And I think that where this comes up a lot is actually in the situation of, for example, atrial fibrillation, where patients will often be put on a blood thinner. And many people are fearful of blood thinners. They worry about the risk of bleeding. Maybe they know a relative who's had a bleeding complication from a blood thinner, and so they may be disinclined to try it. And so, it's really important to have these discussions about the risks and the benefits of medication and engage the patient in thinking about this. And there are even tools and visual aids that people can look to to help explain some of these complicated concepts to patients. So, these are the kinds of things that reflect implementation science as a way to improve adherence. We know what works in a clinical trial setting often, but the challenge is translating that into the real world and getting our patients to use the medications that we believe scientifically have been shown to be of benefit. I've actually been surprised sometimes at conversations I've had with people, in some cases, healthcare professionals who resist going on blood thinners because of their fear of the complications. And I feel like the evidence is there. Why don't they believe me? And that's why it's really important to have the conversation. Even our peers and colleagues can sometimes question the evidence, and it's important for us to be aware of that.  Dr Grouse: Absolutely. I think that sounds very reasonable to me, and hopefully these tools will help us with making some of these decisions with our patients. Now, turning our attention a little bit to secondary prevention. So, you know, someone's already had a stroke or a TIA, sort of thinking about what we can do to optimize their risk factors for further strokes. You know, I think there has been some changes that have happened, I think, in the last few years that might be affecting some of the decisions we're making and some of the advice we're giving our patients. I wanted to talk a little bit about GLP-1 receptor agonist medications. Is the data there to support use of this either in secondary prevention or even in primary prevention in the case of stroke?  Dr Elkind: There is evidence that supports the use of GLP-1s for stroke prevention. We need more data, though. We need trials that focus only on patients with stroke, for example, there have been studies in patients with cardiovascular disease broadly that include stroke patients. But if you look at the subcategory just of stroke patients alone, the data in that subgroup alone don't always show a benefit. And so, we need more data that's focused on stroke patients alone. So, I think the data are continuing to emerge, but we need more still.  Dr Grouse: Is there any development in the thought about whether we should be putting patients on antiplatelet therapies for incidental, incidentally identified strokes? For instance, if you got an MRI for migraine or for other reasons and you found one, no history of any stroke-like symptoms. Should we be putting these patients on aspirin or any other types of therapies?  Dr Elkind: That's a really great question. And again, it's an area where there's some controversy and really, there's really no definitive data that would support using antiplatelet therapy in people with incidentally discovered infarcts or what we call, you know, whispering strokes or silent strokes. Many stroke neurologists will use antiplatelet agents. This is one of those areas where it's so important to identify the risk factors. As we were saying before, patients who have other neurological disorders like migraine or epilepsy may turn out to have cardiovascular risk factors like diabetes and high blood pressure. That's why it's so important for neurologists to be able to treat those patients or refer them to specialists who can. Patients who have incidentally discovered lesions similarly are a group where we should be looking for risk factors. So, I don't think of it only in terms of do we put them on an antiplatelet or not, but really more holistically, can we identify their other risk factors and address those? Should the patient's information be entered into a risk calculator like PREVENT, for example, so that we can come up with a more global or holistic measure of their cardiovascular risk and address that as appropriate? Because if they are at risk for stroke, they're also at risk for cardiac events, including heart attack, heart failure, sudden cardiac arrest, and so forth. So, I think of it as a, as a great kind of teachable moment or an opportunity to catch somebody and bring them into the healthcare system more broadly and address those other potential risk factors.  Dr Grouse: Speaking of, of risk factors that we often like to think about and work up when possible, in cases where it seems certainly possible the patient had an embolic stroke, but perhaps we've done a few weeks or four weeks of cardiac monitoring, have not found any evidence of atrial fibrillation. What's new and what's the current recommendations for doing further monitoring when there's high suspicion for cardioembolic stroke?  Dr Elkind: This is a really active area of investigation, and guidelines suggest that we should do some cardiac monitoring for atrial fibrillation after an unexplained stroke, but it's not clear how much we should do. Studies generally show that the longer you follow somebody on a cardiac monitor after stroke, the more likely you are to detect atrial fibrillation. It could be as high as thirty percent after a few years. And that's great. And if you detect atrial fibrillation, people usually end up being recommended for a blood thinner. But how extensively we should monitor remains unknown. And I think a lot of the investigation recently has been around the question of, are there other ways to get that information rather than waiting six months or a year for the person to develop atrial fibrillation?It's a little bit funny logically to think a person has a stroke today, a year later you discover atrial fibrillation on the monitor, and you say, "Oh, now I know what caused your stroke a year ago." Right? The temporality, the causality perhaps is off in that case. And so, wouldn't it be better if we could tell what somebody's risk of having another cardioembolic stroke is, or the likelihood that they have atrial fibrillation is at the time that you first see them for the stroke, you know, in the hospital, for example. And so, there's some really new technologies that have evolved like AI or artificial intelligence interpretation of EKGs that can give a really good indication of which people are gonna go on to develop atrial fibrillation. And so, I think we need some more trials in that area to demonstrate that we can detect the risk of AFib and treat that even before it appears on one of those delayed monitors. That's an area that I think is very exciting right now. There's also a further question with regard to how to treat these patients, which is that sometimes atrial fibrillation is a consequence of the stroke itself. So, we can think about what people call known AF, meaning atrial fibrillation that's known about before the stroke even occurs, versus AF that's detected after a stroke, or AF-DAS, people will say. Those may have very different implications for the risk of recurrence and what the person's cardiovascular status is. So, I think what we've learned over the last few years is that atrial fibrillation, it used to be like the slam dunk for a stroke neurologist. It was the easy thing. You know, you had a stroke, you have AFib, you should be on a blood thinner. Now we know that there's lots of different kinds of AFib. There's AFib before stroke, there's AFib after stroke, there's burden of atrial fibrillation. So, some people may have 30 seconds of AFib, some people may have several hours, some people may be in it continuously. It comes and goes, and that can make it challenging to manage. So, we have a lot more work to do to understand this problem better.  Dr Grouse: That also gets me into some other interesting areas that I think there's still some question, you know, how aggressive should you be? How often is it a case of is this correlated or is this causative? For instance, when a patent foramen ovale is, is discovered in patients with cryptogenic stroke. Are there any tools or new developments to help us understand whether these PFOs should be closed in these cases?  Dr Elkind: PFO and stroke is a great story that's been going on for decades. And again, we've made tremendous progress in the last several years. So, it's true that about 20% or so of people have a PFO, and because of that, it can be really hard to say with any certainty whether an individual patient sitting in front of you, that the PFO was the cause of their stroke. Rarely we can have a really high degree of certainty. You know, if somebody has, uh, a DVT, for example, and shortly after that maybe they have pulmonary embolism and then a stroke, and we can say, "Oh, clearly this was a paradoxical embolism," went to the lungs and then some crossed over and went to the brain. That happens really infrequently. Most of the time you're faced with a patient who has a PFO and a stroke, and they may have some other risk factors. There are some tools that we can use to help figure out the likelihood that a PFO is related to a stroke. One of those is called the ROPE score or the risk of paradoxical embolism score that was developed by David Thaler and, uh, David Kent from Tufts and a group of other investigators as well. That score allows one to say what the likelihood is that the PFO was causative of the stroke, and it's based on a person's risk factors such that the younger you are, the more likely it is the PFO caused the stroke. And the absence of risk factors make it more likely that the PFO caused the stroke. So, the higher your ROPE score indicating the fewer other reasons you have a stroke, the more likely the PFO is to be causative. So that can be helpful in identifying patients who may have had a stroke due to their PFO. There are other features that are identified in something called the PASCAL score, which is a way of assessing the degree of shunting and whether or not there's an atrial septal aneurysm that can be used as additional factors that lead to the likelihood that a PFO was causative rather than just incidental. So, by putting this kind of information together, we can kind of do precision neurology or precision prevention by identifying which patients with a PFO are really the ones we need to worry about and do procedures like closure.  Dr Grouse: I look forward to hearing more and learning more as more advances are made in these areas.

Social determinants of health, including housing, food access, insurance status, and structural inequities, significantly influence stroke prevention, recovery, and long term outcomes. These factors affect biological risk, treatment adherence, and disparities in care, even when traditional clinical measures are addressed. This episode highlights practical strategies for integrating screening, leveraging multidisciplinary teams, and identifying opportunities for advocacy to improve patient outcomes. In this episode, Teshamae Monteith, MD, FAAN, speaks with Nneka L.

Dr Monteith: This is Dr. Teshamae Monteith. Today I'm interviewing Dr. Nneka Ifejika about her article on social determinants of health and their impacts on stroke prevention and outcomes. This article appears in the June 2026 Continuum issue on cerebrovascular disease. How are you? Welcome to our podcast. Dr Ifejika: Thanks for having me. I'm doing great. Dr Monteith: Great. So, can you introduce yourself to our audience? Dr Ifejika: Sure. I'm Dr. Nneka Ifejika. I am the Chief Scientific Officer of Ochsner Health System in New Orleans, Louisiana. But I'm also a cerebrovascular rehabilitation doctor. I've been practicing for about nineteen years, and am happy and honored to be a contributor to this Continuum Neurology article. It's a really important topic. Dr Monteith: Great. So, what got you into this field, first of all? Dr Ifejika: Well, I was deciding between PM&R and neurology, and I was putting in both match lists. And I thought about it and I leaned toward PM&R, but stroke still had a grasp on my heart and my mind. And so, after I finished my residency, I joined the UT Houston stroke team, and I did a, thankfully did a two-year fellowship and became cross-trained in stroke as well as physical medicine rehab. So, I am a jack of both trades. Dr Monteith: So, you got your way in a way. Dr Ifejika: I did. Dr Monteith: You know, we have a lot of learners that are listening, so it's always, uh, nice for them to be inspired, I think, by people's career paths. So why don't we talk about the objectives of your article? Dr Ifejika: Sure. So, one of the most important things that we wanted to do was make sure that medical students, residents, faculty, and fellows understood the impact of social determinants of health on stroke recovery and stroke rehabilitation. It's not as simple as you have hypertension, hyperlipidemia, we're going to manage your stroke risk factors. Oh, you had an ischemic stroke. You presented in time for the window. We're going to give you endovascular therapy and then modified Rankin scale at hospital discharge in ninety days. No, no, no. The stroke survivor and their caregivers and their family have a lot more to deal with outside of what we look at during the acute stroke hospitalization and post-acute rehabilitation. Things like, can they afford the medication that we're prescribing? Antiplatelet agents or anticoagulation can be extremely expensive. Do they have housing insecurity? Is there food insecurity? What's going on behind the scenes that we are not addressing that can directly impact the admission rate and the readmission rate after we take care of a stroke survivor? Dr Monteith: I love the article because you took a real deep dive into social determinants of health, what they are, why they matter, and what we can do about them. And so why don't we talk a little bit about the NINDS framework for social determinants of health? I think many of us might not be familiar with the framework per se. Dr Ifejika: So, the framework consists of multiple domains specifically that relate to social determinants of health that were published in Neurology a couple of years ago. So, I do hope that people who are hearing this recording actually read them. There are interpersonal domains, there are classic medical domains, there are indeterminate domains, and there are six total domains. And health domains are the last domain. So, things like when it comes to housing insecurity, food insecurity, that's a domain of social determinants of health. When it comes to chronic racism, when it comes to biases that patients experience, those actually impact outcomes. So, there are six separate indices that we're going to get into in detail and how we address them as clinicians, whether it be at the medical student level, resident level, faculty level, to integrate the social determinants of health in our care plans, because we could be doing a much better job. And I think it'll be really important from the interpersonal perspective when we really relate to our patients and their families that we ask these questions. For example, if we're prescribing someone to have treatment for their diabetes mellitus and ha- and, and be taking insulin, if they have housing insecurity and they're in a homeless shelter, they have to leave the homeless shelter during the day. So, what happens to the insulin that we prescribe? These are variables that we are not considering on a regular basis, but they directly relate to compliance. Dr Monteith: Great. So that was one thing I wanted to bring up. We're very good at measuring blood pressure and trying to determine, uh, the association between stroke outcomes and things that we can measure, glucose, lipids, blood pressure. What is the evidence for social determinants of health and stroke outcome? Dr Ifejika: The evidence is growing, and there have been many publications that have come out that are, are going to be highlighted in this article related to structural determinants of health inequities, like structural racism, as well as disparities related to ethnicity and race. There's geographical disparities. For example, a lot of patients are, are primarily concerned about rural versus urban, whether you have access to different post-acute rehabilitation, whether you have access to secondary stroke prevention because you simply don't have the transportation from a, a rural area to get to a drugstore to get things available to you. Social status. There are actually publication related to socioeconomic status and the concerns when it comes to air pollution. So particulate matter 2.5, we know that that has a direct impact on stroke outcomes and health overall, but we don't really think about it as a structural determinant of health inequity. There's several multiple layers of research that have gone on specifically that have been cited in the literature that relate directly to social determinants of health and how we can address them moving forward. Dr Monteith: And what I found interesting in your article in that you gave at least a few examples where social factors like income, education were controlled for, and maybe in large part it is, but even when you control for some of these very obvious social risk factors, you still have inequities. Dr Ifejika: Absolutely. And I think it was really important to show that we had strong peer review evidence behind this, as it wasn't just something that we were creating or hypothesizing about. There have been studies that have been done over this over decades of time, showing the impacts of social determinants of health on outcomes. But the question and concern that we have is we know this growing body of literature continues to expand. What are we doing about it when it comes to education of the future generations of providers who will be caring for this population? Dr Monteith: Before we get into how, you know, what we're going to do about that, let's just kind of put that link, cause the evidence is there. How does it drive biology? Dr Ifejika: It's a great question. So, for example, particulate matter 2.5 in air pollution has been shown to have an existing impact on hypertension, raising your blood pressure. So that's a direct effect of a social determinant of health related to socioeconomic status because people who live in areas with higher air pollution are... They're not green spaces. They live near highways. Those are areas that unfortunately are also impacted by food deserts. Food deserts, if you're not able to get fresh fruits, vegetables, whole foods, increases your risk of developing diabetes, hyperlipidemia, also increases your sodium intake, again, increasing hypertension. These things are all connected to biological determinants. It's just that we're not asking about them necessarily within the social history when we're taking people into the hospital, but they have direct effects. Dr Monteith: Great. Neurologists tend to be busy and, you know, we're... have all of these things that we're being asked to do and chart and click and all of that stuff. And so how can we more readily integrate screening for social determinants of health and that conversation into the work we do? We recognize it's important. We recognize it's an important risk factor. There's a lot of these determinants. So, what is a good way to do so? And I, I know that in the paper you've, you've given different roles to different team players, so I want you to talk about that too, but just kind of even a regular routine office visit. Walk us through a way we can more easily integrate that kind of conversation. Dr Ifejika: It's an excellent question, and what I've recommended that we do in a standard office visit is utilize the time before the visit to send out screeners. So, for example, usually with an electronic medical record, you can send documents before the visit even starts, where people can check off whether they have any concerns regarding housing, food insecurity. They can check out their location of where they live, whether they live near a highway or not near a highway. It's specifically related to socioeconomic status. We can ask about insurance status, whether they have insurance, insured versus uninsured, but then also types of insurance, whether they have Medicaid insurance versus Medicare insurance. Then even drilling even further, type of Medicare insurance, Medicare Advantage versus traditional Medicare, cause all of those things actually play a role in this. Dr Ifejika: And evaluate these things and don't take time during your office visit. Send these screeners out beforehand. Have them be assimilated by your medical staff. Make sure you're utilizing every resource that you have at your disposal to help streamline things, so by the time the person comes in for the visit, you've primed the pump. You have this information already in your hands at your fingertips cause it was sent out in advance, and you have your medical staff already have an understanding of. If they didn't fill it out electronically, give it to them in the lobby. Make sure they have a handwritten copy in the lobby so that when they come into the office visit, you have the information at your fingertips. Dr Monteith: Are there any particular resources that you recommend for those types of screeners? Dr Ifejika: What I've used in the past, if you have patient-reported outcomes, so the PROMIS instruments, that's a good start. It doesn't get into the details of housing insecurity, food insecurity, but it's a good start to help prime questions and to start the conversation during your office visit. In my clinics, I do a PROMIS 27 on every patient, as well as a PHQ-9 for depression on everyone. And then I collect data longitudinally, and I can always drill down on factors that I noticed that could become a problem moving forward. Dr Monteith: Yeah. And then also in your article, you spoke a bit about this impact from the acute presentation in the hospital to rehab. Dr Ifejika: Yeah. Dr Monteith: So why don't you talk about these different entry points where we can really engage our patients and try and help reduce their burden? Dr Ifejika: Sure. So, healthcare can be quite fragmented, and the stroke patient, stroke survivor, and their family member have no grasp of that. They've had a stroke, and they may be going from the ER to the ICU to the stroke unit to the floor to the rehab unit, and we see it as multiple levels of care, multiple types of providers. They see it as one hospital. And the concern that we have is, at those branch points, things get dropped, and we have the opportunity to pick things up at those branch points. So, during the acute care hospitalization-Primarily, that's the establishment of what has happened, how we're gonna treat it, what are the variables that we can control for right now to address those determinants of health moving forward, and to specifically looking at whether they were taking medications before, whether they could afford medications before, what that looks like at hospital discharge. Is there any duplication of medications? If a person is taking Coreg and you prescribe metoprolol, but they still have the Coreg at home, should we have really prescribed the metoprolol? We're just spending money that they may have concerns when it comes to access to care and the cost of these prescriptions. So, it's the responsibility of the acute care physician to kind of look at that. Those are subtle things that we think are subtle, but they add up quickly for the family when it comes to having one group of medications that's the same class and having to buy another type. When it comes to post-acute rehabilitation, it's really an important time to screen for whether the caregiver can handle what's occurring. So specifically, if the caregiver is already burning out and the average length of stay for a stroke patient is five days and they've come to rehab for two weeks, what's gonna happen in the next two years or the next four years? So, during the post-acute rehabilitation phase, it's time to kind of look at that and drill down on those kind of questions. Also, the levels of care, Dr Ifejika: it's really important to look at other levels of rehabilitation, so skilled nursing facilities, making sure people have access to that if they need to, if the caregiver is burned out and they don't have the ability to go straight home. Because acute inpatient rehab, the goal of it afterwards, is to go straight home. It's not to go to another facility. So, you need to have that screener in place when it comes to whether the family can take care of this person, and whether the family can do it in an effective way to prevent them being readmitted. Dr Monteith: Great. I also like that you spoke about kind of the team approach and different roles, both for screening and for intervention, both being very important, especially the intervention. And so why don't you give us a few examples how the team could break up the responsibility and how also for the intervention component that can be done. Dr Ifejika: Sure. So, I broke up the team into several levels. So, the team medically is the medical student, resident, and faculty physician. However, the team also includes the support staff, so your case manager, your social worker, the therapist, physical therapy, occupational therapy, speech therapy, the pastoral services, all these members of the team. You know, sometimes as physicians, we don't read those notes. There's a lot of information in the notes from social work, care coordination, and the therapist. They get down to subtleties cause they're asking questions, for example, "What kind of equipment do you have at home? How many stairs do you have at home? What level of house do you have, one story, two story? If you live in an apartment, do you have an elevator access?" That's important for someone with hemiparesis. When it comes to medications, when it comes to insurance status, when it comes to your ability to have the mechanisms to pay for care as an outpatient, social workers are required to ask these questions cause they have to figure out resources for the patient and their family to help facilitate improved outcomes. So, they have to ask questions regarding these tasks. The concerns are, do we read what they're saying? So, it's really important to interact with them, and if it's not something that you're looking at in the chart, cause we're all so tied to our computers, find where they are in the hospital. Walk by their office and have a chat. Run your list with them, especially for people who you're concerned have vulnerabilities, and make sure that you're setting an example for your medical students with your faculty doing so. If you're looking at it from the medical student, resident, faculty perspective, medical students, listen. This is your opportunity to really contribute to the team as well as learn about social determinants of health and research in their fields. You are the boots on the ground for the medical team. You are the ones who should be priming the pump and asking these questions of the family members. We're sending you into the rooms to do a history and physical. Social determinants of health should be a part of your history and physical, and you should be taking what we're saying in this article and asking these questions and tying it into your resident. Now, the resident is the work person of the hospital. We all know this. Things run through the resident. Things run through the fellow. It's really important that they have this information in a manner that is negotiable. The list keeps getting longer, and a resident doesn't need to be overburdened. It needs to be synthesized in a manner that can help facilitate the resident being able to act as well as communicate any concerns to the faculty. And at the faculty level, we are the voices that can affect change. So, if there's any concerns when it comes to advocacy, research, making sure that people are accessing care in a way that makes sense, particularly when it comes to the ability for us to galvanize change on a national level, that's kind of our job. Dr Monteith: Great, and so let's talk about intervention. What are things that, let's say, the neurologist can do to deal with some of these social factors? Dr Ifejika: From the neurology perspective, I think it's really important to identify missed opportunities and making sure that we address them. For example, the conversations around the ability to have access to care related to insurance versus no insurance. There are many, many ways that neurologists are able to advocate for a person being able to get to Medicare insurance, particularly in the outpatient setting. When we see patients in clinic, it takes two years, them, to qualify for Medicare, two years at a minimum. But there's a gap there that can be filled by us making sure that we document what's happened, contact their providers, facilitate communication with their employers, if they're employees, they can get some short-term disability benefits to help bridge that gap prior to receiving Medicare insurance. It behooves us to do this because if we do not, they fall into the gap and they get readmitted and they're back on service anyway. So, what's important is the outpatient that we really kind of focus on things that we can impact and things like insurance and getting people transitioned from having employer-based insurance versus getting to Medicare is a really important way that we can effect change in a, in a way that's viable and, and replicable. So, in the outpatient setting, neurologists have a wonderful opportunity to effect change in social determinants of health. When it comes to employed persons, who had a stroke transitioning to Medicare, it takes two years to do so. So, in the outpatient clinic, if you have an employed person, make sure that you fill out their short-term disability benefits forms, their long-term disability benefits form. Bridge the gap. Get that information to their employer so they can maintain constant coverage. Because if they do not, if they have to choose between refilling medications and putting food on the table, they're going to choose putting food on the table, and that's going to directly impact their outcomes if they're not taking the medication that we recommend. Dr Monteith: I think that's a great point. I mean, there's a lot that we can do, and in some ways, it may not take that much to document and to be able to ask the questions and to include some of that information into the assessment and plan is really a, a great idea. Dr Ifejika: And you know, if we don't bring these things up and have these conversations, it doesn't get addressed. And that's why I'm very, very thankful that I had the opportunity to do so, cause this is a part of what I do all day. I think that if I wasn't integrating these kind of conversations into my practice, I wouldn't have the ability to share these tips and these abilities to move things forward in a manner that will be constructive for our field overall and for our patients. Dr Monteith: And towards the end of the article, you brought up something I think we don't see in many articles, and that's the role of advocacy and getting involved in health policy. So, can you talk a little bit about that? Dr Ifejika: You know, it's really important to facilitate change when you see that there are things that need to be changed. And the best way to do that is through advocacy at the local or state or federal level. A lot of these variables that we're dealing with can be addressed through legal changes. I'll give you an example. End-stage renal disease, if you have immediate hemodialysis and you have that requirement upon hospital discharge, you qualify for Medicare immediately. Immediately. Before you even leave the hospital. Why wouldn't something be similar for a stroke? Well, the reason why is because there was a level of advocacy that came around end-stage renal disease and a member of Congress's wife had hemodialysis requirements. And so, a law was passed to make sure Medicare covered it immediately after hospital discharge. So, it requires advocacy in some significant ways to get things done, but we have the bandwidth to do this. We take care of a population that has some of the highest rates of preventable disability. That's not going away. We need to make sure that we're effecting change for this group to make sure that they have the best possible outcomes they can experience. Dr Monteith: So, any final messages for our listeners? Dr Ifejika: I look forward to hearing everyone's feedback about our issue. I am thankful for the opportunity to talk about, address, and write about this important topic, and look forward to everyone's feedback. Dr Monteith: Well, thank you so much for being on our podcast. It was a really wonderful summary and we had a very thorough conversation, but you didn't give away too much, so I think they're going to have to read the article. Dr Ifejika: You're going to have to read the article. And we want medical students, residents, fellows, faculty, all of our ancillary staff within the hospitals, please read this article. We really appreciate it. Dr Monteith: Again today, I've been interviewing Dr. Nneka Ifejika about her article on social determinants of health and their impacts on stroke prevention and outcomes.

DescriptionIn this episode of Perfect Prey, I'm joined by Ann Burgess, pioneering forensic nurse, researcher, educator, and author of Expert Witness. Ann's groundbreaking work transformed how professionals understand trauma, victimization, sexual violence, and offender behavior. Her research has influenced criminal investigations, forensic psychology, victim advocacy, and some of the most well-known criminal cases in modern history.Together, we explore the long-term impact of trauma, why victims are so often disbelieved, and how systems continue to fail those who come forward. Ann shares insights from decades of work studying victims, offenders, serial violence, child abuse, and the psychology of coercion and control. We also discuss institutional betrayal, trauma responses in children and adults, family court failures, pornography, grooming, and what it takes to create meaningful change within systems that were never designed to fully protect victims.What we coverAnn Burgess's pioneering work in victimology and forensic nursingHow trauma impacts behavior across the lifespanWhy victims are often disbelieved by systems and institutionsInstitutional betrayal and systemic failuresCoercive control, fear, and psychological abuseTrauma responses in children and adolescentsChild sexual abuse and delayed disclosureFamily court, victim credibility, and expert testimonyThe role of pornography and grooming in abusive behaviorThe Menendez case and evolving understandings of traumaWhy trauma-informed education is critical for professionalsHow offender thinking patterns develop and escalateWhy listenIf you are a survivor, clinician, attorney, advocate, educator, or protective parent, this episode offers a rare opportunity to hear from one of the most influential voices in trauma and victim research.Ann Burgess's work helped shape how we understand trauma today.

But what do we have to learn about preventing them altogether? The science of stroke prevention, acute treatment, and recovery are evolving rapidly, and it's hard to keep up. Today, we're speaking with Dr. Cheryl Bushnell, guest editor of our latest Continuum issue on Cerebrovascular Disease, to discuss these topics and much more.  Dr Jones: This is Dr. Lyell Jones, editor-in-chief of Continuum. Thank you for listening to Continuum Audio. Be sure to visit the links in the episode notes for information about subscribing to the journal, listening to verbatim recordings of the articles, and exclusive access to interviews not featured on the podcast.  Dr Jones: This is Dr. Lyell Jones, editor-in-chief of Continuum: Lifelong Learning in Neurology. Today, I'm interviewing Dr. Cheryl Bushnell, who is Continuum's guest editor for our latest issue on Cerebrovascular Disease. Dr. Bushnell is a professor of neurology and the director of the Center for Transformative Stroke Care at the Wake Forest University School of Medicine in Winston-Salem, North Carolina, where she specializes in the care of stroke patients and their social and functional determinants of recovery and health, and is an internationally recognized expert on those topics. Dr. Bushnell, welcome. Thank you for joining us today. Why don't you introduce yourself to our listeners?  Dr Bushnell: Absolutely. Thank you for the invitation. It's really an honor to be here. So, as you mentioned, I am the director of the Center for Transformative Stroke Care at Wake Forest. It's a really fun transition for me to be involved with different care models for stroke, and I think a lot of the Continuum topics are directly relevant to some of the things that I'm doing now as an administrator and sort of a facilitator of new research. So, thanks again for having me.  Dr Jones: Yeah, and, and you have a wonderful perspective, and we're gonna pull that out today in our interview questions, and I'm looking forward to sharing that with our listeners. But before we get to the questions, we're gonna start off today's podcast with another Continuum Audio trivia question for our listeners. Anticoagulation has played a critical role in secondary ischemic stroke prevention for a long time now. While direct oral anticoagulants have taken on a greater role in the treatment of prevention of stroke, there are still some use cases for vitamin K antagonists like warfarin. The trivia question for our listeners is this: How was warfarin discovered, and how did it get its name? Stick around and we'll share the answer to that question toward the end of our interview today. So, Dr. Bushnell, let's get right to it. You alluded to your various roles, and your leadership in the field has been exemplary. The interventions for acute ischemic stroke have really exploded over the last decade or so, and they get a lot of attention and discussion, but prevention and recovery are just as important in the care of these patients. Tell us a little more about how you approached this issue, about the article topics you chose, etc.  Dr Bushnell: Well, once I was chosen to lead the guest editorship, I wanted to come up with a group of topics that were maybe a little bit different from previous issues. So, I kind of looked at the previous issues and saw, as you said, an emphasis on acute stroke, and that's really important because it has been evolving. But my thought was, how about what happens to patients after they get the intervention and they're discharged home? And because a lot of trainees may not get to see these patients ever again, or it's months before they might see them, or if they're readmitted, which is what we don't want to see, but that certainly is a lot of the exposure is in the inpatient setting. So, I thought I would kind of transport the education into the outpatient and transitional setting, as well as prevention, not only secondary, but primary prevention, with an emphasis on brain health. Some of the populations that may not get as much attention. So, sex differences, stroke in women, pregnancy, the transitions of care, and also the emphasis on holistic view of patients and their challenges, which includes the non-medical factors that drive health, otherwise known as social determinants of health.  Dr Jones: I appreciate that perspective, and obviously th-this is an area of your deep expertise, and it's great to have an issue that really digs into some of those topics a little more deeply. As an educator, I'm really glad you mentioned that about the trainee's perspective. You know, especially junior neurology trainees that are in the hospital all the time. They're seeing patients in the middle of a cerebrovascular catastrophe. But there's a long tail of recovery, right? And they'll get to see that in continuity clinic, but it's a good message to share from an evidence and, um, experiential perspective in the issue. So, appreciate that perspective. You've just read all these articles and edited them. Was there anything that you ran across that was a surprise to you?  Dr Bushnell: Well, I personally chose a lot of the authors based on my knowledge of their work. So, I wouldn't say that it was completely surprising, but I do think that I was just genuinely impressed with the quality of the writing and the synthesis of information. I just was incredibly proud of the work that these co-authors have put together. I'd say that that was-- it wasn't surprising so much as just a sense of pride that I had with the product that's coming out. But of course, there have been some new trials that had to be incorporated at the last minute, some of which were presented at the International Stroke Conference just a few weeks ago.  Dr Jones: Yeah. We try to be as up-to-date as we can, and I will completely agree with you. We have some really good writers in our field, and it's really just a pleasure when you read an article that's by an expert, and it's a joy to read. I can tell you it's one of the best parts of this job, and you get to learn a lot. I think one of the more challenging scenarios that I hear about from colleagues in recent years has been optimal management of patients with asymptomatic extracranial atherosclerosis. The pivotal trials that inform how we manage those patients were from a long time ago, decades ago, predating a lot of the more intensive medical management tools that we have today. In that scenario, Dr. Bushnell, what's the latest on that, and what should our listeners know?  Dr Bushnell: Well, obviously, the CREST 2 trial has been long awaited. It's been going on for over ten years, I believe. Of course, it's, uh, two different trials all in one, the carotid stenting and angioplasty versus intensive medical management. And of course, each of the carotid vascularization arms of the trial also had intensive medical management. And then the other trial is the carotid endarterectomy as the form of revascularization. And it interestingly did not show any benefit of carotid endarterectomy compared to intensive medical management. But of course, the somewhat surprising result was that carotid angioplasty and stenting truly was superior, although it was a small number of events in the trial overall. But that stenting plus intensive medical management was somewhat better than intensive medical management alone. And I think stenting has come a long way in terms of safety, and so I think that's been part of the evolution of the field. I do wanna say that I'm a huge fan of the intensive medical management, and I think that what the protocol does in terms of blood pressure management, cholesterol management is very much above and beyond what's done in private practice even. And the health coaching for all the other things related to diabetes and weight loss and smoking cessation and physical activity, that is what we need to be doing to actually decrease the risk of stroke, and I think that it's very effective. I can't say enough about the design of the study for that reason, that everyone gets the intensive medical management, and then you just layer on the type of revascularization on top of it. So, I wouldn't have been surprised if this was a completely negative trial overall. They just happened to have some better outcomes in the stenting arm.  Dr Jones: I recall a few years ago when the series of endovascular therapy trials for acute stroke came out, and I think there was a, a period of time where the field had to adapt to that. I wonder what you think about with the CREST 2 findings on stenting. I mean, is that gonna be a big change? Because obviously atherosclerosis is highly prevalent. Is that gonna be a big change? Is the field ready for that? How much adjustment do we have in store?  Dr Bushnell: I'm not sure it's gonna be a really big change. If you read the editorial that accompanied the trial in the New England Journal, just a few patients in either direction would have changed the outcome. I kind of look at it as an absolute difference that's relatively small. So, I'm not sure that it will have a huge impact on the field. I do think that the specialists who insert the stents may have some differences of opinion of who should be stented and who shouldn't. Because I think, you know, all of the specialists who do procedures were involved with the trial. But I would say there's a larger percentage of vascular surgeons who were involved, and so I'd say they may have a change of their practice. And neurologists may not even get involved at all.  Dr Jones: Right.  Dr Bushnell: That was one of the challenges for getting patients in the trial is that, you know, not all of us see the asymptomatic carotid stenosis, that they tend to get referred to vascular surgery. So, I think maybe in a corner of the practices of vascular surgeons is where you might see the differences.  Dr Jones: Your point about the way the trial was designed or the trials were designed, that intensive medical management is really important, and we have huge gaps in that. In our specialty, it's, you know, we have probably an opportunity in primary care even to address that. And that leads me to my next question. You know, given your perspective and your expertise, what do you think is the biggest practice gap in the care of patients with stroke or with cerebrovascular disease of any kind?  Dr Bushnell: I think by far the biggest gap is transitions of care and access to follow-up in a specialty clinic after discharge and continuous secondary prevention. We only call it secondary prevention because it happened to come after a stroke, but I really feel like we should just focus on prevention and call it that. There are a lot of people who are trying to kind of, get us away from primary versus secondary prevention. And, and Mitch Elkind is phenomenal and had a beautiful chapter weaving in prevention and brain health. So, I highly recommend that people, if they don't read any other chapters of the Continuum to read his, because I think that it's getting to your point about where the gaps are, and I think prevention is the biggest one. I think we could do so much more in models of care to ensure that there is a pathway once patients are discharged. We have no quality metrics. We have no measurement of how well people are doing after they're discharged. We have all of these fancy things and sophisticated acute treatments, but all of those are for naught if somebody goes home and they fall and they have a severe head injury or hip fracture because they weren't properly supervised or they didn't have the help that they needed at home. So, you got me on my soapbox here for a second, but that is definitely what I see as the gap.  Dr Jones: That's an important soapbox, an important gap, and obviously, if it was a simple problem, we could solve it. But it's obviously something that education is a valuable tool for that, and that's part of why we are including so much content in this issue of Continuum. So, if we put that aside as a gap that we would love to close, when you look into the near future or distant future, Dr. Bushnell, and what's the next big thing on the horizon? New interventions, new prevention tools, or something else entirely? What do you think?  Dr Bushnell: There are two things that I would mention. One is sort of the new category of anticoagulants, antithrombotics, the factor XIa inhibitors. We had an amazing presentation of the oceanic stroke trial at the International Stroke Conference, and this is probably going to be a game changer for the arsenal of antithrombotic therapies that we can offer to patients that do not have a reason for anticoagulation. So, they, they don't have atrial fibrillation, for example, or something else that requires anticoagulation. And so, the factor XI, asundexian, is the drug that they used in that trial. The safety profile is pretty amazing. There was very little bleeding complications and a great benefit in those patients with some degree of atherosclerosis, but, you know, of course, not enough to require carotid revascularization, but then also, um, small vessel disease and cryptogenic stroke. I think those are the three categories of patients, and that's a lot of the strokes that we see all benefited from this new drug. So, I think that's gonna be exciting. There, of course, it has to go through the FDA approval process, and so it might take a little bit of time before that's on the market, and we don't know how much it's gonna cost, but I think it is a, a major breakthrough. And of course, there are other similar medications in that category that are coming. And then I think the other thing is the emphasis on brain health and lifestyle factors and the things that we can do to prevent stroke and dementia because they are the same, essentially. Those are really important. And when we have someone in the hospital with a stroke or a TIA in particular, it's a great teaching opportunity for those patients to say, "Hey, here's what you can do to protect your brain." These are things that we always tell people to prevent a stroke, but just think about it as protecting your brain and keeping your brain as healthy as possible.  Dr Jones: That's a great message, and one that you get to share with patients directly. You're joining us today for this interview. You're on stroke service, so you're actively involved in caring for patients with stroke. What in your practice is the most rewarding aspect of caring for these patients? What is it that you find most rewarding?  Dr Bushnell: I've been involved in a clinical trial that has focused on managing blood pressure and also coaching and other aspects of stroke recovery. I think that has probably been the most rewarding aspect of my career. Until I was involved with this trial, I didn't necessarily do intensive blood pressure monitoring, but I'm seeing the benefits of having data from home, what those blood pressures are over a span of time. I see the immediate or intermediate effects of the blood pressure medication changes that I've made, and I see how the patients respond. So, I have to say that this is not part of usual practice, but I think it should be. And I think it's been incredible from the perspective of a neurologist who is really intensively trying to make the patients' lives better. And it's not just what I do, it's what the health coaches do as part of this intervention. And again, very similar to intensive medical management. So, I, I feel like I've been living it in a slightly different setting than in the CREST 2 trials. But there are other trials that have used the intensive medical management as approach as well. But I would say that's the most rewarding. I've seen people who've lost weight, who are physically fit, who are able to get off of blood pressure medications practically by the end of six months, and that's amazing. And then they continue doing it because they see the benefits.  Dr Jones: You've had a front row seat to a lot of that. That's really got to feel rewarding.  Dr Bushnell: It is, absolutely.  Dr Jones: You know, when you put it that way, it makes me want to go home and check my blood pressure, which I haven't done in a while. But I think that's a message to all of our listeners that we do have plenty of opportunity for risk factor optimization and following the evidence that has been generated and is being generated. Huge opportunity, not only at the population level, but I think the, um, individual patient level too. Okay, so now we're back to our Continuum Audio trivia question, and I'll repeat it for our listeners. How was warfarin discovered, and how did it get its name? Dr. Bushnell and I were talking about this earlier, so I'll just go ahead and share the answer. So, in the early 20th century in the U.S. Midwest, there were epidemics of a hemorrhagic disease in cattle, of all places, and this was eventually traced to moldy cattle feed that was made from sweet clover. And in 1940, researchers at the University of Wisconsin discovered that the anticoagulant in the sweet clover was a compound that was later synthesized for therapeutic use in 1954 as warfarin. And the name came from, uh, the support for the research. The research support came from the Wisconsin Alumni Research Foundation, or WARF, and the end of the word came from the underlying compound, which was coumarin. So that was a little bit of trivia that I had never heard. It's not in the issue, everyone, so you're getting something extra here on the podcast. But been using the drug forever. It still has its uses, even though it's become less advantageous than some of the newer agents. But-- And of course, Dr. Bushnell already knew that when I brought it up, but I just thought that was an interesting bit of history. Well, Dr. Bushnell, thank you for joining us. Thank you for such a great conversation about the latest in cerebrovascular disease. I learned a lot today. I learned a lot in reading these wonderful articles. I hope our listeners learned a lot today as well. I'm really grateful for your hard work on the issue, which I think will come in handy for junior readers and subscribers, as well as our more experienced neurologists as well. Sometimes it's hard to keep up with a rapidly changing subspecialty of our field. So, thank you for joining us today.  Dr Bushnell: Thank you for having me. It's been my pleasure.  Dr Jones: Again, today we've been speaking with Dr. Cheryl Bushnell, guest editor of Continuum's most recent issue on cerebrovascular disease. Please check it out, and thank you to our listeners for joining today.  Dr Monteith: This is Dr. Teshamae Monteith, Associate Editor of Continuum Audio.

Photo by Reproductive Health Supplies Coalition on Unsplash In June of 2022 in the case of Dobbs v. Jackson Women's Health Organization, the Supreme Court overruled Roe v.Wade on the basis that access to abortion is a state issue. Since that decision, some states have passed laws restricting or banning altogether women's access to abortion. But the Food and Drug Administration approved the distribution of Mifepristone for medical abortions without an in-person visit as a safe practice. Louisiana filed a lawsuit against the FDA for this action and at the end of April 2026, the Fifth Circuit Court of Appeals ruled in favor of Louisiana, restricting women's access to the drug in states that have banned abortions. On May 4th, the Supreme Court ordered a halt to stopping access to the drug until May 11th so that both sides could respond and the court could consider the issue more fully. HealthCetera host Diana Mason, PhD, RN, FAAN, discussed the case of Louisiana v. the FDA and the Fifth Circuit Court of Appeal's ruling with Anna Beernstein, principal federal policy advisor for the Guttmacher Institute, a research and policy organization committed to advancing sexual and reproductive health and rights worldwide.

Photo by Igor Omilaev on Unsplash Artificial intelligence (AI) is already upending our world. It's being used in health care in a variety of ways, including for interpreting x-rays and other imaging, flagging potential concerns that a clinician may overlook, and supporting diagnostic decision-making. There have been suggestions that robots and AI could even replace nurses. Needless to say, there are a lot of concerns within the nursing community about how AI is used in health care. In recognition of these concerns, the American Academy of Nursing issued a position statement on Artificial Intelligence in Health Care. HealthCetera host Diana J. Mason, RN, PhD, FAAN, discussed this position statement with  Debra Barksdale, RN, PhD, FAAN, president of the Academy and Dean of the University of North Carolina at Greensboro School of Nursing.

Photo by Patty Brito on Unsplash The U.S. healthcare system is in crisis. COVID strained health care organizations and stressed healthcare workers; and it seems that we've not yet recovered from that nightmare. We're unlikely to see the system recover in the short term and it may take a lot longer, as the Trump Administration and Congress make cuts to tax credits for health insurance, Medicaid, and other health programs. The leaders of healthcare organizations are focused on the bottom line to survive but some exceptional healthcare administrators are also focused on supporting their staff, particularly nurses who provide the bulk of care. They know that you can't have quality healthcare with good outcomes if you don't address employee satisfaction. But what does this work look like? How do healthcare organizations such as hospitals ensure that nurses and other healthcare workers are provided with the support they need to be able to do their jobs well and feel joy in their practice? The American Nurses Credentialing Center has looked at this for nurses and has an initiative called Pathway to Excellence that focuses on how organizations can create positive practice environments that empower and engage staff, and recognizes the organizations that do create such environments. HealthCetera host Diana J. Mason, PhD, RN, talked about this work with Christine Pabico, RN, PhD, FAAN, Senior Director of the Pathway to Excellence Program for the American Nurses Credentialing Center. This interview first aired on HealthCetera in the Catskills on WIOX Radio on April 29, 2026. The post Providing Nurses & Other Healthcare Workers with Support appeared first on HealthCetera.

When blood collects in the skull outside the brain and below the outermost layer of tissue surrounding the brain (dura), a subdural hematoma results. This may occur due to head trauma when it is called an acute subdural hematoma. Chronic subdural hematomas may occur due to aging and the increased fragility of blood vessels. The pooled blood may resolve on its own or may require surgical intervention as development of a subdural hematoma can be a life-threatening condition. Symptoms of subdural hematoma can include headache, confusion, change in behavior, dizziness, nausea and vomiting, lethargy or excessive drowsiness, weakness, apathy, and seizures. Subdural hematomas are generally diagnosed by CT scan or MRI imaging. Ashkan Mowla, MD, FAHA, FAAN, is neuro-interventional surgeon at the Pacific Neuroscience Institute® (PNI).

Today, I'm interviewing Drs Penelope Smyth and Janis Miyasaki about their article on palliative care in multiple sclerosis, which appears in the April 2026 Continuum issue on multiple sclerosis. Welcome to the podcast, and please introduce yourselves to our audience.  Dr Smyth: Thank you, Katie. I'm Penny Smyth. I am a neurologist at the University of Alberta, a professor in neurology, and a clinical multiple sclerosis specialist.  Dr Miyasaki: Hi, Katie. Thanks for having us. I'm Janis Miyasaki. I am a movement disorder neurologist primarily who also provides neuropalliative care at the University of Alberta in Edmonton, Canada.  Dr Grouse: It's so great having you today to talk with us about your article. I thought this article was really a wonderful take on the topic. I learned a lot, and I'm really hoping all of our listeners will take advantage of this article and take advantage of all the learning they can get from reading about this topic. So, I wanted to start with a more general question, which is, what is the key message from this article that you're hoping your readers will take away?  Dr Smyth: In terms of key takeaways, I think it's our hope that neurologists will come away from reading this article with, really, an expanded understanding of what palliative care is and how that might be applicable to them in their care for their patients with MS along a continuum of treating people with MS, that there can be components of palliative care and strategies that can be integrated early after diagnosis in, really, anywhere along the continuum of caring for people with MS. We've called that kind of mid-stage. And then there are particular needs for people with MS and their care partners in late-stage or severe MS and end of life that might require different palliative care strategies. I think we kind of have maybe a bit of a bias sometimes in thinking of palliative care as more directed towards those that are near end-of-life. But in fact, it's a much expanded concept.  Dr Miyasaki: And I'll just add that we also discuss a palliative approach, that palliative care skills and philosophies can be used by generalists---in this case, neurologists who are providing care to people with MS---and that adopting certain skills and communication techniques can help us better address our patients' and their families' symptoms. And also to keep in mind that for most people with neurologic illness, the unit of care is not only the patient, but it's the patient and the family, however that family looks.  Dr Grouse: Now, Penny, I'm curious, how are early-stage and mid-stage multiple sclerosis palliative care strategies different from, say, a typical evaluation and counseling that a neurologist would give, say, an MS specialist or even a general neurologist?  Dr Smyth: Thank you, Katie. That's a great question, and something that actually I learned in writing this piece with Janice and from her as a neuropalliative care expert. I think in terms of early strategies around palliative care that can be helpful to the general neurologist in their office, palliative care is about holistic support for patients and their care providers spiritually, emotionally, physically. There are components of palliative care and symptom management and making sure that the patient is at the center of the care, as well as support for their care partners with their holistic approach of relief of suffering as well as offering hope. When I started this piece, I was thinking that many of us neurologists, I think, often informally utilize many of these components already when we're dealing with patients early on after diagnosis in terms of communication, counseling, and education; going through their fear of an uncertain future; spiritual well-being; and then connecting them with supports for adaptive coping strategies. And then as well in mid-stage, which is really around what we can do in symptom management and improving quality of life, with screening tools and patient-reported outcome measures. However, I have to say that there are many unmet needs for people with MS and their care partners that they identify that are clearly not being met by us neurologists in this day and age. So even though we may be incorporating some of these strategies, I don't think we're meeting the mark all the time and hitting the target, especially in our busy office practices, in various ways. Dr Grouse: Given that, at a high level, what are some important early-stage MS palliative care concepts that we should be keeping in mind when we are counseling patients in these stages of the disease? Dr Miyasaki: An important concept to keep in mind for neurologists dealing with early-stage MS patients is that for us, we feel successful that we have made a diagnosis. And yet for the patient, it is taking away that hope. Maybe it's not MS. Maybe I just have a numb hand and it's gonna go away. And for us to appreciate that while we make this diagnosis multiple times a week---or, for MS specialists multiple times a day---for this person, it is the first time, the first experience, and it shakes their entire foundation of who they are as a person, how they will perform all the tasks and roles that they have in society, in their professional lives, in their family structures, and in their close, intimate relationships. As physicians, we may be overwhelmed by acknowledging that. I feel that it's important for us to understand the needs that our patients have and to allow them to have their feelings. You know, feelings can feel messy and time-consuming, and yet when we fully see our patients, I feel that this is the best of medicine. And it certainly is, in terms of palliative care, the principle that we seek. We accept all of the patient, the joy and the sorrow, the anger and the frustration. We accept it all, and we try to determine what will serve this person who is suffering in front of us now.  Dr Smyth: There's another piece to this, which came up as Janice and I were writing together. We were talking about offering a prognosis to a patient as to how they would do, and this was something that I thought deeply about, because I said, we always communicate how uncertain the prognosis is and how we can't predict the future. And then she said to me, well, what about offering a roadmap to a person with MS soon after diagnosis as to how you're gonna determine how they do over the next couple of years? Which are really important years in terms of determining how patients are doing on their disease-modifying therapies, whether they're having progression or not, and things. It's a pivotal time. So, if you can offer a roadmap to a person with MS and say, look, this is when we will be following you up. This is how we will be following you with MRI and biomarkers if you have that available, and this is how we will determine how responsive you are and then how we move forward from there. Dr Grouse: Really important concepts. And the roadmap certainly makes a lot of sense to me and something that, apart from just being useful to the patient for so many reasons to help set expectations, you know, is useful for us to better partner with the patient so they understand this is sort of how we do things and everyone's sort of expectations are met. So, I think those sound like really great goals and things to keep in mind. Now, we talked about early-stage MS palliative care concepts. How does that change as you get into the mid-stage of the disease?  Dr Smyth: Yeah. So, this is reflecting the fact that the course of MS is so different and the experience of MS is so different person to person. And so, what do we do as neurologists when we follow these people long-term over years and decades of living with their MS as their needs evolve, as their symptoms evolve, and as their disability evolves? Well, really, this is about the time of getting into, what are the symptoms that they're struggling with, what are the causes of their suffering at various points? And then how do we identify that, maybe with use of patient-reported outcome measures, screening scales, things like that. And then how do we direct symptomatic management to the specific symptoms that are causing distress to the patient? As well as trying to improve their quality of life in various ways, treating their comorbidities, making sure to check on exercise, healthy living, and that kind of thing.  Dr Grouse: Now getting into, I think, topics that we're more used to thinking about when we think about palliative care: a lot of us, I think, are really unsure of the right time to discuss advanced care directives in the course of multiple sclerosis, and I think that's not helped by the fact that many of us are just, in general, not terribly comfortable talking about those types of things in general. What is your advice to questions like this?  Dr Smyth: And this is something that, again, Janice and I had to come together on, because there is no universal accepted time for when is the right time in multiple sclerosis to discuss advanced care directives and goals of care. And in fact, when they have looked at it in the literature, different things have come out. It has come out that neurologists can be uncomfortable discussing this. There's unique challenges to people with MS in that they have a diagnosis at a young age with an uncertain trajectory of how their course of disease is going to go. And many of these things lead care providers to be somewhat hesitant as to when is the right time, as well as, there were identified barriers within patients themselves as to when the right time might be to discuss. In that, you know, some of the coping strategies might be, as identified by some of the qualitative studies that have been done on this, around the fact that they would prefer to focus on the present rather than the future. In some studies expressed an ambivalence as to when they thought the right time might be, as well as some negative experiences that they might have had from providers trying to discuss these things in their previous experience. So, I went back to looking at the European guidelines for palliative care in MS, who suggested when a person might have severe MS---which they define as walking with bilateral aids for at least twenty meters or an EDSS of six or higher---or trigger-based, when there has been a change in the patient's status, when there's been a decline in some way or progression. Now, this is a little different, actually, than what we offer other people with neurologic diseases, and I don't know if that's the right answer. And this is where I'm going to turn it over to Janice, because I think we could learn something, as neurologists who treat people with MS, from our palliative care specialists.  Dr Miyasaki: I think of advanced care planning in a very different way. I think what a lot of the patients were expressing in the studies was that being asked about advanced care planning signaled to them in some way that they have reached this point in their illness where things aren't going so great and I anticipate that you may run into complications. Whereas in our movement disorder clinic, one of our fellows did a study looking at capacity for decision-making. And even in people who scored normally on the Montreal Cognitive Assessment, they had impairments in some of the domains of decision-making. And so, our philosophy in movement disorders at least---and some of our patients are quite young who have multiple system atrophy, they could be in their forties---we take the philosophy that everyone over the age of decision-making capacity, which is generally eighteen, should have some goals of care established. And how I introduce it in my clinic is, you know, for the young resident, you want the full-meal deal, because the likelihood of the resident surviving the ICU admission is very high. And then when we look at me, who… I am older, the likelihood of surviving an ICU admission is considerably lower. And so, the appropriate goals of care might be that I am willing to go to the ICU, and if things go well, then they can continue. But if things are not going well, they can have a discussion with my personal directive or power of attorney to talk about what the goals of care should be. And then the other aspect is sometimes having the conversation with family is really important because most of our families in hospital express an uncertainty. Am I doing the right thing? And they want to do the right thing for their loved ones. And most people actually say, if you ask them, I don't want to burden my family with making decisions that are going to tear at their hearts. So, then we can't actually make good informed decisions for our loved ones unless we have clear conversations. I think it does speak to our superstitious beliefs that if we talk about death, it's going to happen. But I hope the listeners will take my word for it, it really doesn't. And someone had a really good saying about the advanced directive. They're kind of like evening clothes. You should take them out every once in a while and make sure they still fit. And so, when you normalize it in this way, it helps people to just say, oh, yeah, it's once a year. Dr. Miyasaki is gonna ask me about how do I feel about those goals of care. And then it doesn't have this portent of, oh, I'm not doing well. Instead, it's just, this is what we should all be doing for our sake and for our family's sake.  Dr Smyth: Now, one thing that I have to add on to this is that it is important to try to establish advanced care directives before patients experience cognitive decline, because then that can make it a much more challenging conversation and brings nuances of challenge into the interactions, which, you know, are hard.  Dr Grouse: And Penny, I'm glad you brought that up, because I was really struck by that point too when reading this article, how easy it is to miss the subtle signs that cognitive changes are happening. I think it's just- it's a good kind of segue into that topic in general, but it is such an important link to, you know, making sure that you get those advanced directives at a time when the patient's really able to express and understand what they're talking to you about. Now, on the topic of the cognitive screenings, what's a good way to do this type of screening, and why is this type of screening so particularly important in the case of multiple sclerosis?  Dr Smyth: Yeah. Thank you, Katie. I think that it's important for our listeners to think about and recognize when we see our patients with MS because it is one of the invisible symptoms that people with MS can live with and may not be apparent on regular conversation in the office. So, it's important to deliberately ask about subjective challenges in cognition. Ask the partner about how they're doing in terms of their cognition in various ways. As well as asking them and exploring then, how are they doing in their professional roles if they're working or in their surroundings? How are they coping on a daily basis on a cognitive level in addition to a physical level? We know that cognitive issues are actually the biggest contributor for not working and are a huge driver of disability in MS in terms of functioning, even more than physical decline in many ways. So, it is important for us neurologists to keep top of mind and to think about and deliberately attend to. There are screening tests that we can do in the office. The easiest for us, which measures the verbal processing speed, is the SDMT test, which is a ninety-second test matching symbols and numbers. It's easy to do. You can train a MOA to do it before you see the patient and things like that, and it just gives you an idea as to where the patient is at. And usually they're having difficulties if they're greater than two standard deviations below the norm for their age, or if there's a significant drop of four or eight points, and that might signal to you that there might be more going on. You can explore it, and then if you do have this available, the ability to refer for neuropsychological testing if there's questions. But often we can't get it with the MoCA score, unfortunately.  Dr Grouse: Talking about all these concepts, I think they all sound great. I think a lot of us hearing this will naturally say, "Yes, these are absolutely things we should be incorporating in the care of these patients." What I wondered about was, certainly we're all very busy, it is really hard to find time for a lot of these things. We don't always have access to specialists who can help us with some of these conversations. How can we find time, and how can we work this into the care of our patients effectively and still make time for all the other things we have to talk about, and make sure that we're seeing all of our other patients and staying on time and all of those things?  Dr Miyasaki: Yes. I think that's the challenges of dealing with people who actually, over time, their care needs increase, is huge in neurology. I can't think of a single subspecialty where care actually gets easier. It's constantly getting harder. You know, having come from private practice, I completely understand my colleagues' challenges in the community. Some of the ways that other groups have managed this when they don't have government or university support in their center is actually to look at not-for-profits. There are a lot of not-for-profits that can help in terms of wayfinding for social services, explaining to the patients and the family what is available to them. And in fact, some of them can also provide some cognitive supports, as well as point them in the way of day programs. And many of them have very established caregiver support groups, as well as patient support groups for various stages of their illness. So, I think it requires for the individual or small or even a large group practice to be inventive, to look in your community and see what resources are available and free for your patients in order to establish that loose team without boundaries to help your patients. Of course, for those in academic centers, I know that times are tight for all of us, and if you haven't established a team, it is a challenge; and then learning how to write a business plan or a briefing note for your institution and to learn how to speak the love language of administrators, is really key to putting forward the needs of our patients. Which, compared to heart attack patients or hips and knees, they are very rare, and yet our patients can result in significant cost to the healthcare system. So, we do have an opportunity to make the case that putting a little bit of investment in the ambulatory setting can result in significant cost savings to the system when it comes to acute care hospitalization.  Dr Smyth: So, I was thinking, Janis, as you were talking about that, when you were talking about not-for-profit groups, it's really the MS societies in various countries that are very active in this and have a lot of resources available, especially for care partners.  Dr Grouse: Those are really great tips. Thank you for bringing those up as potential other resources we can take advantage of. I wanted to ask specifically about physician-assisted death and assisted suicide, which certainly does come up, especially in later-stage parts of the disease. How can palliative care specialists be helpful when patients do express interest in these types of interventions?  Dr Miyasaki: As you know, Katie, in Canada, we've had a legislative right to access to what we call medical assistance in dying. When the legislation passed, one of my other colleagues and I felt that these were the only conversations we were having with our patients. In all this experience, I have sort of developed in my mind a framework of people who are what we call MAID-curious. They want to know what their rights are and how it would look, when they feel the time is close, for them to exercise that right. And then there are those who are fearful of future suffering. And some of them may have a very unrealistic view of what the future will look like. And this may be in particular for multiple sclerosis because many of the public's view is based on what treatment was like thirty years ago. It may not be informed by more recent treatment where patients actually do quite well, and the majority never get to progressive MS. And so, to explore and be open to that request is the first thing that is important. And then if the person has unresolved symptoms that, traditionally, we can't care for, the palliative care specialist can be very helpful because they just have inventive ways of looking at things. They look at it outside the box, and they have a different toolkit available to them. I would not want all neurologists to just send all these patients requesting physician-assisted death to their palliative care colleagues. But I think for those who are having unaddressed symptoms, it can be very helpful. Certainly, if there is an acute event in the hospital, then this is a time of crisis. And often hospitals will have an in-hospital palliative care team who can come and speak to the patient about what is going on and address some of their needs. And I would also like to emphasize the importance of spiritual care, because for many of our patients, they are not just having the physical suffering, they are also having the spiritual suffering of hopelessness or of feeling that they are a burden or that they just are not seen because a lot of the symptoms in MS are invisible. To have that understanding by a spiritual care counselor is really helpful for the people to feel understood and to reduce some of that suffering.  Dr Grouse: That's a really great point, I think, to end on, and I think it really ties in a lot of the themes that we've been talking about today. Thank you so much for coming to talk with us today. It's been such a pleasure having you both here. Dr Smyth: Thank you. Dr Miyasaki: Thank you, Katie.

In this episode of the Society of Critical Care Medicine (SCCM) Podcast, Diane C. McLaughlin, DNP, AGACNP-BC, CCRN, FNCS, FCCM, is joined by Aarti Sarwal, MD, FAAN, FNCS, RPNI, FCCM, and Brian L. Erstad, PharmD, FCCP, FASHP, MCCM, to discuss the 2026 guidelines for neuromuscular blockade in adult patients with acute respiratory distress syndrome. The guidelines, “Society of Critical Care Medicine Guidelines for the Administration of Neuromuscular Blockade in Adults With Acute Respiratory Distress Syndrome,” were published in the March issue of Critical Care Medicine. Drs. Sarwal and Erstad discuss how the evidence in two key trials, ACURASYS and PETAL-ROSE, has helped shape the recommendations provided in the SCCM guidelines. Despite how influential these trials were in shaping the recommendations, only conditional recommendations were made due to low or very low quality of evidence. The lack of evidence proved to be a driving factor in including a call to action in the guidelines. Future research priorities largely revolve around precision medicine and finding more patient-specific interventions to improve patient outcomes. Aarti Sarwal, MD, FAAN, FNCS, RPNI, FCCM, is a professor of neurology and the division chair of neurocritical care at Virginia Commonwealth University (VCU) School of Medicine in Richmond, Virginia, USA. She is also an associate editor of Critical Care Medicine, secretary of the American Society of Neuroimaging, and director of VCU-Wake Forest neuro-ultrasound courses. Brian L. Erstad, PharmD, FCCP, FASHP, MCCM, is a tenured professor and interim dean at the University of Arizona R. Ken Coit College of Pharmacy in Tucson, Arizona, USA.

However, with every new treatment comes new risks; and in the case of immunomodulatory therapy, many of those risks relate to infection. Today, I have the privilege of talking with an expert on this topic, Dr Avindra Nath, about the infectious risks of treatments for multiple sclerosis and other immune-mediated neurologic disorders.  Dr Jones: This is Dr Lyell Jones, Editor-in-Chief of Continuum. Thank you for listening to Continuum Audio.

This article appears in the April 2026 Continuum issue on multiple sclerosis. Welcome to the podcast, Dr Nath, and could you please introduce yourself to our audience?  Dr Nath: Thanks very much for inviting me to this podcast. I'm absolutely delighted to have the opportunity to discuss our areas of interest and expertise related to infections and vaccinations for MS patients. My area has been studying the infections of the nervous system since the beginning of the AIDS pandemic, and over the years and decades, we've developed expertise related to various types of CNS infections. That includes ones that are developing in individuals who have immune compromise due to a variety of different reasons. Dr Berkowitz: Fantastic. Well, glad to have the opportunity to speak with you today. When I was in medical school---and you were my attending, actually, we were just reminiscing, which we probably think was not that long ago, but is now over twenty years ago---there were just two medications for MS, right? Beta interferon and glatiramer acetate. And now we have over a dozen, and it's amazing to think of all the progress in these last two decades, as well as for related diseases like NMO. I don't think we even had the aquaporin-four biomarker, right, when I was working with you as a med student in the early 2000s. Dr Nath: And that certainly dates me a lot.  Dr Berkowitz: Both of us.  Dr Nath: Yeah.  Dr Berkowitz: Of course, with all these new treatments, these have been amazing advances for our patients, right? But these come with new treatment-related risks to monitor for with the immunomodulatory medications for MS and related disorders. And one of those most important risks is that of infection. So, your article reviews the potential infectious complications of medications used to treat MS, NMO, etc, and also covers considerations related to thinking about vaccines in this patient population. So, as the MS treatment landscape grows, I can say as a general neurologist, keeping up with all these medications and what to screen for and what to worry about and when to vaccinate just becomes more challenging every year. And your article has so many helpful tables, some organized by medicine, some organized by- sorry, medication, some organized by infection, some by vaccines. So, this is gonna be a great resource for our providers to print out and tape up in their clinic rooms. We won't be able to get into all the depth and detail that you have in this article today, but I do want to focus on some of the key points here related to the common medications we use for MS and which infections to think about and which vaccine considerations we might need to keep in mind for these medications. But before we delve into the drugs, I just wanna ask you more broadly, you talk in the article about the challenge of patients with immune-mediated diseases who are on immunomodulatory therapy being at risk for both flares of their disease and for infections; and these infections can present somewhat atypically, right, in immunomodulated hosts, to maybe coin a term you can correct me on, because they can't mount the full inflammatory response. So how do you approach new symptoms in patients on these immunomodulatory medicines as far as distinguishing disease flare from a treatment-related infection?  Dr Nath: So, I have to say that although a lot of new treatments have come along for MS, and they've really, you know, improved the outcome tremendously and there are so many different options, it has also kept people like me relevant because they cause a lot of various types of infections, and so keeps me in business all the same. But just as you mentioned, there's so many of them, even I have difficulty keeping track of what does what. So, you do need to be able to refer back to published literature, and the tables, I hope, will be quite useful in that regard. You're absolutely right, and you can get new infections, you can get reactivation of existing infections, and you can get atypical presentations of various types of infections that you may not normally think of. So that presents multiple challenges to the treating physician. The other interesting thing about MS is, just as you mentioned, that you already have CNS lesions to begin with. Now, on top of it, you have an infection, so now how to sort out what is the existing disease and what is the infection, it can again become challenging. But one thing is for sure: all these infections are caused by an organism. So, what you really need to do is, the underlying diagnostic is to demonstrate the presence of the organism. Whether you demonstrate it depending on the infection in the spinal fluid or in the brain or, you know, some peripheral organ system, that is going to be key to making the diagnosis. So, all your clinical acumen is good, but that alone may not be sufficient. Dr Berkowitz: Very good. So, when you see a, a patient now who has a new neurologic symptom in the context of an immune-mediated disease who's on immunomodulatory therapy, what goes through your mind? Are you thinking this disease and this drug, and sort of what are the infections, and does the syndrome match? Or are you thinking, you know, you can't always rely on the imaging to distinguish between, say, a flare of an MS and PML because white matter lesions could look similar? How do you sort of approach this scenario when it comes up?  Dr Nath: So, you're right. You have to keep an open mind so that even though you know some infections are more likely to occur with certain types of medications, that doesn't mean that others cannot occur. So, I think when you first see the patient, you should not jump to conclusions, but rather have an open mind. But yes, for example, your patient is on natalizumab, the chances of PML are going to be high. It's a very interesting drug. It does not cause immune compromise in the periphery, but what it's doing is preventing these cells from getting into the brain. So, because then it's acting at the blood-brain barrier. So that means that organisms that are already present in the brain have an opportunity to get reactivated. Turns out you don't have a lot of organisms in the brain, except JC virus seems to be one of them that does somehow, in some individuals, manage to reside out there. And so that can get reactivated. It can get reactivated in the periphery and then enter the brain, too. So, where the very specific mutations have to occur in that virus in order to take residence in the brain. That would be a suspicion that you might have, and MRI can be useful in, again, helping you think about that possibility. If you have typical lesions involving the U fibers, they're demyelinating, usually you do not have much edema around them because patient is immune compromised, but certainly within the brain in these individuals. And so, then you need to demonstrate the organism. The demonstration of the organism should be in the spinal fluid and not in the blood because in the virus, it can-- is reservoir in the kidneys and in the lymph nodes, and periodically it'll shed into the blood. Detection of the organism in the blood can be a false positive, but in the spinal fluid, it shouldn't be there unless you have an infection. Or if you cause a traumatic tap, I guess, if a patient is viremic, that's a possibility, but those are extremely rare. So at least for PML, that's the way that you would diagnose it. Now, you can develop, for example, if an individual is on fingolimod, you can get a wide variety of infections. Here it's a totally different type of mechanism of action. Here the cells are trapped within the lymph nodes, so that means now your entire periphery is immune compromised, right?  So here you can get viral infections, bacterial infections, fungal infections. So here, if a patient presents with new neurological symptoms, you have to have a really open mind for all these possibilities. Now, let's say a patient was on dimethyl fumarate, and dimethyl fumarate causes neutropenia early on. So here you have to worry about an individual developing bacterial infections, so latent tuberculosis or bacterial meningitis can occur in these individuals. That's something to keep in mind. It's not that other infections cannot occur with dimethyl fumarate, you can see PML and other things too, but the chances of bacterial infections are greater. So, you got to make sure that you draw all the cultures for that purpose. Similarly, if you're on a complement inhibitor, like a C5 inhibitor or the thing that I could use in NMO, there are the chances of meningococcal meningitis. So, these patients, you need to prevaccinate them before you start these kinds of treatments and look for that possibility. When you suspect bacterial infections, particularly acute bacterial meningitis, there time is of essence. Also, in some of the acute viral infections, for example---herpes encephalitis is another one---you have to be so careful, and if you suspect any of them, even if they're with possibly atypical manifestations, you treat first and then diagnose later, and draw all your cultures, whatever you need to, and just treat them. And these infections can also cause cerebral edema, so one has to be careful about doing spinal taps in these individuals. You want some kind of neuroimaging before you do them. In the days when we didn't have neuroimaging, we used to say, "Okay, if your patient has focal neurological signs or is comatose, you don't do it." But these days, you can get imaging very quickly and very easily. All the-- Because of our stroke management, we've learned how to do them so quickly. So, I think there's little excuse not to do imaging and prevent herniation from occurring.  Dr Berkowitz: That's very helpful. So, using the information we know about the drug, and we're going to rapid-fire review some of that in a bit to know what infections the patient is susceptible to, but acknowledging that any patient can get any infection, right? Whether they're on particular medications or not. And then if you're not sure, based on the neuroimaging, which as you said, is helpful, but not always helpful in distinguishing between infections and flares or, as you said, in the case of meningitis, encephalitis, early on at least, especially in immunocompromised or immunomodulated, quote unquote, patient might not see the typical imaging. So really, when safe, getting CSF or cultures, PCRs, and other infectious studies too is really gonna be the definitive diagnostic maneuver here. Is that fair summary across the board?  Dr Nath: I think you said that absolutely right. And you summarized that correctly. And, you know, thing about infection, a lot of neurological diseases are, you know, diagnosed by clinical acumen, like your Parkinson's and Alzheimer's and others. Think about infections is caused by an organism, demonstrate the organism, right? That should be your goal. It doesn't mean that clinical acumen is not important, but here you have an opportunity to demonstrate the organism, so you should depend upon that.  Dr Berkowitz: Okay. Well, you gave us a nice segue by talking about some of the infections to worry about with some of the medications. So what I'd like to do now for the sort of second half of our interview here is to go through some of the more common medications used for MS, and if we have time, for NMO, and just sort of go kind of rapid fire here, and for each medication, if you can tell us the kind of top infectious concerns and whether when to consider them or what screening needs to take place before or during administration of the medication, and then any vaccine considerations we should be aware of. Some of these will obviously be quite short depending on the medicine. So, going back to the two medications I alluded to earlier that were the only ones in play when you and I last saw each other on the wards when I was a medical student, beta interferon, glatiramer acetate, any infections or vaccine considerations with these medications?  Dr Nath: No, I think they're probably your safest medications now as far as immunomodulatory therapies are concerned. These two, and IVIG, if you ever use them, are probably the safest, do not require any vaccine considerations, per se. Dr Berkowitz: Perfect. Okay. So, moving on to fingolimod and others in the sphingosine-one phosphate receptor modulator family, what are the infectious considerations? Any prescreening or vaccination considerations?  Dr Nath: I think all your patients should be prescreened for antibodies to JC virus, because there is a risk for PML, and those who are positive should be closely monitored. So, it's not an absolute contraindication for using these medications, but they just require closer monitoring. With this class of drugs, PML is of consideration. Also, these varicella-zoster virus infection, yeah, with that you can develop zoster encephalitis or myelitis. It can present with motor symptoms as well, which can be atypical. You don't usually see them otherwise in immune-competent individuals. So, varicella-zoster, sometimes you can develop encephalitis, also vasculitis with varicella-zoster, so one has to be careful. So, getting the shingles vaccine can be actually very helpful to prevent these things. And then some patients can even develop herpes simplex encephalitis also, and that can be extremely atypical. So, they don't- they can involve the basal ganglia, can involve the brain stem and cerebellum. So again, your index of suspicion should be very high. Interestingly, although HSV encephalitis has been associated with NMDA receptor encephalitis, those reports of NMDA receptor encephalitis have not been published yet with NMS patients. Not sure why, maybe they just have been missed. But that doesn't seem to be a major concern. And then there are a whole host of other infections that can occur with this class of drugs, and that can include toxo; fungal infections, particularly crypto. There's a case report of histoplasmosis; hepatitis virus, particularly hepatitis C; and then the poxvirus is a good example. You can get molluscum contagiosum; warts with papillomavirus; you can get atypical mycobacteria; and even Kaposi sarcoma, which is HHV8. So, there's a huge variety of infections with the sphingosine one phosphate receptor modulators.  Dr Berkowitz: And any- aside from screening for JC virus before initiating these, any- and then continuing to monitor for JC antibody index, any other considerations as far as labs to send, monitoring before or on the drug or vaccine considerations for patients on fingolimod and the others in this category, siponimod, etcetera?  Dr Nath: Yeah, there are a lot of things to consider. All the details are really available in the chapter if you look at them. But briefly, all the things that one could potentially vaccinate patients for, all these infections I mentioned, one should do so. The timing is critical so that if you can do it before treatment, I think, before starting treatment, that is absolutely important. And you got to give them at least, you know, two to three weeks for these vaccines to take effect before starting your medication. If your patient already arrives on a medication, then you got to play this game of you know, before the next dose, give them again two to three weeks before the next dose and start vaccinating them and get all the vaccines in. Broadly, about the things to worry about the vaccines are you have live vaccines, and you've got the inactivated vaccines or the subunit vaccines. You have to be careful with live vaccines, because if your patient is immunocompromised, that virus can sometimes itself cause harm. For example, you know, yellow fever is one, and there you can develop encephalitis from it. Measles, mumps, rubella, these are all live vaccines. Now, the good thing is that a lot of us have been immunized very early in childhood, but that may not be the case any longer. And so, these things, one has to be very careful with when you're giving live vaccines, that we want to avoid them as much as possible, and individuals are gonna be immune-compromised. But all the others, meningococcus, for example, you should- the HPV vaccines, the varicella zoster vaccines, all these things, you've got to pre-vaccinate and make sure that they have an antibody response to them before starting immunocompromising therapy. Dr Berkowitz: Perfect. Okay, moving on to some of the other orals. What infectious and/or vaccine considerations do we have with teriflunomide?  Dr Nath: Okay, yeah. Teriflunomide is a very interesting drug. It's relatively safe. There is concern about the possibility of varicella zoster infection, people have reported that, and also tuberculosis. But PML is extremely rare, if not at all, and we haven't seen herpes encephalitis quite yet.  Dr Berkowitz: Got it. How about dimethyl fumarate? Dr Nath: Yeah. So dimethyl fumarate is... as I mentioned earlier, it's interesting because it causes this neutropenia. It's transient, but it occurs early on, and these patients can be at risk of PML, although small. They can develop varicella zoster virus infection, herpes encephalitis, and also fungal infections. For example, cryptococcal infection has been reported with dimethyl fumarate. Dr Berkowitz: Okay. We've spoken a bit about natalizumab and PML, and you have extensive information on this in your article, and I'll defer the reader to that. But for natalizumab, what are the key points every neurologist should know about natalizumab and PML as far as from the practical perspective, screening, frequency of screening, when to worry, when to not use natalizumab at all in the first place based on what you find in your screening for JC virus? What are the key points every neurologist should know?  Dr Nath: Uh, yes. You bring up an important point, and that is all patients should be monitored for JC virus. If they're JC virus-negative, so that's your most ideal patient to go on natalizumab, but that doesn't mean they cannot get infected with the virus. In fact, there's an interesting study claiming that, you know, patients, when they get these infusions, they're all sitting in the same room getting infused. Some have JC virus, some don't have JC virus, and so there's the potential that we may be aiding the transmission here in some way or another. The virus is an interesting one. It comes out in urine, and then it's spread through oral contamination, gets into the tonsils, and then spreads from there to your marrow and resides in the kidney and the marrow, as well as the lymph nodes, forever. So, you, you have to monitor these patients to see that during the course, even if they're negative, they could turn out positive. So, every six months or a year, an antibody test should be done on all patients irrespective. If a patient already has antibodies, that's not an absolute contraindication. It just means you've got to monitor them closely for development of new symptoms, and if, whenever there are new symptoms, don't just assume this is due to MS, but just make sure the MRI is done with and without contrast. The- and if there's still a suspicion, that you do a CSF evaluation for JC virus. Just detecting, looking for JC virus in the blood, a rising titer is another thing that can help you. And so, the titer is also important. And the reason you have rising titers is it means that there's an infection that's already occurred in the brain, and the immune system is reacting to that infection by increasing titers. But that alone is not sufficient to make the diagnosis. You still- that gives you an index of suspicion. You've got to then do the MRI and the spinal tap to, you know, be absolutely certain. So, each patient is a little bit different, so the way you monitor them is going to depend on where they are. You know, if they've had prior immunomodulatory therapy before starting natalizumab, or if they're on natalizumab for more than two years, then the chances of PML are much greater, so you may want to monitor them more closely. Uh, they never had any prior immunomodulatory therapy, you're just starting natalizumab, maybe once a year is sufficient. So, I think you've got to tailor it depending on what your risks are for each patient. Dr Berkowitz: Perfect. That's very helpful. And again, you write extensively about PML and natalizumab and PML considerations in your article. So, for a more detailed and in-depth discussion of what we just discussed, definitely hope readers will take a look at your article. Okay. Last but not least---certainly not least, 'cause we're using these probably, it seems, the most commonly in many places I've worked---rituximab, ocrelizumab are B-cell therapies for MS. What are some of the infectious and vaccine considerations related to these infusion medications?  Dr Nath: So, there's concern for PML with anti-B-cell therapies also, maybe not to the same degree as natalizumab, but the same principles should be applied. A lot of people think that these are relatively safe. I don't think so. I think we see enough number of patients on B-cell therapies with PML. So, I would use the same caution because these infections are... you know, can be fatal. So, one should be very careful, even with anti-B-cell therapies. And just with natalizumab, you also have the risk of VZV infection causing shingles. HSV1 has been reported, but there's another interesting complication that has been reported with anti-B-cell therapies, and that is severe West Nile encephalitis. And as mosquitoes-borne diseases are getting more and more prevalent, and we're seeing West Nile cases erupting every summer, I think one's got to be, you know, very cognizant of the fact that this can occur. These patients should take precautions to prevent mosquito bites from occurring and not expose themselves to areas where they could be at risk for it. Unfortunately, there is no vaccine for it and no specific treatment for West Nile. So, all one can do is use prevention strategies for mosquito bites.  Dr Berkowitz: Yeah, I'm glad you mentioned that. I think the only really truly severe neuroinvasive cases I've seen of West Nile virus have indeed been in patients who were being treated with B-cell therapy. Not, if I'm remembering correctly, for immune-mediated disease, but for a lymphoma, so probably other confounding factors there. But yeah, it's a disease we learn about and think about, but I've only seen the most severe cases in patients who had abnormal immune systems, so I'm glad you flagged that. This has been a very helpful discussion, and I've learned a lot from you. I learned a lot from your article, just as I did when you were my attending some 20-something years ago on the wards when I was a medical student. So, it's good to continue learning from you through your writing and research, and today from getting to talk to you again. I encourage our readers to read your article and to bookmark those tables for when these considerations come up for your patients on these immunomodulatory therapies and you're wondering which infections to worry about and how to manage vaccines in this patient population. So again, today I've been interviewing Dr. Avi Nath about his article on vaccine considerations and infection risk in multiple sclerosis and related disorders, which he wrote with Dr. Amit Bar-Or. This article appears in the April 2026 Continuum issue on multiple sclerosis. Be sure to check out Continuum Audio episodes from this and other issues, and thank you again to our listeners for joining today.  Dr Nath: Thank you so much, Aaron, for that wonderful interview, and I'm extremely proud of all your accomplishments over the last 20 years. You've done an amazing job, and it was such a pleasure to see you and to be able to do this interview with you. Thank you again.  Dr Berkowitz: Thanks. That means a lot. I never would have imagined- we won't say 20, how many, but 20-something years ago as the medical student looking up to you and all your expertise on these infections and all of your research that led to so much of our understanding on these, that I would find myself interviewing you two decades later. So, for all the students listening, you never know where you'll end up, but I appreciate your very kind words.  Dr Nath: That's what we hope for all our students. Thank you so much.  Dr Berkowitz: Thanks again.  Dr Monteith: This is Dr. Teshamae Monteith, Associate Editor of Continuum Audio.

Dr. Monteith: This is Dr. Teshamae Monteith. Today, I'm interviewing Ds Ellen Mowry and Daniel Ontaneda about their article on treatment of multiple sclerosis, which they wrote with Dr. Darin Okuda. This article appears in the April 2026 Continuum issue on multiple sclerosis. Welcome, both of you. How are you?  Dr. Mowry: Great. And thank you so much for having us.  Dr. Monteith: Absolutely. So, why don't you both introduce yourself?  Dr. Ontaneda: All right. My name is Daniel Ontaneda. I'm a neurologist at the Cleveland Clinic. I spend the majority of my time doing research, but I still dedicate about a day a week to seeing people with MS in clinic.  Dr. Mowry: I'm Ellen Mowry. I'm also a neurologist, but practice at the Johns Hopkins University. And similar to Dan, I mostly work on research, but also have an active clinical care component, taking care of people with MS.  Dr. Monteith: Well, thank both of you for writing this article and being on our podcast. I assume you guys have probably known each other for quite a while now.  Dr. Mowry: Yes. Dr. Ontaneda: Yes. Dr. Monteith: What inspired you to get into multiple sclerosis research and then clinical care?  Dr. Ontaneda: I always loved neurology, and I think a lot of us who go into neurology are attracted to the complexity of the human brain and how the nervous system works. But what really hit home to me was a family member of mine who had multiple sclerosis, and he was being treated in a time where we really didn't have super effective disease-modifying medications. And so, as I went through my medical career, I always kind of kept an eye on what was happening with multiple sclerosis, and I started my training at a time where it was really flourishing in terms of the medications available, so that's what inspired me to go into MS. It's a disease that we can definitely treat, and you can change outcomes for people. So, that was it.  Dr. Monteith: Yeah, that personal experience can be very impactful.  Dr. Mowry: My journey started, actually, because I was thinking about whether I wanted to be a physician at all, and I happened to land, just after high school, a position with a neurologist who happened to mostly focus on multiple sclerosis and taking care of folks with multiple sclerosis. And by the end of the summer, I knew I wanted to go to med school and I wanted to be a neurologist and I wanted to work with people with MS. I thought I would be a clinician exclusively, but I think as time went on and I started to hear the consistent questions that people I served were asking in the clinic and realizing that those questions could be turned into research projects that could address their concerns, I moved more and more towards research. Dr. Monteith: Great. There are a lot of really detailed information in the article, so I think that research mind is very useful, and I see that in the writing. Why don't we talk about the goal of the article? Dr. Ontaneda: So, I think the goal of the article was to set out kind of what the large view of what treatment for multiple sclerosis looks like. And, you know, many times we divide the treatment of multiple sclerosis into these large pillars, and I think that's what we did in the article. The first was, you know, what do you do with a person who has an MS attack or relapse? The second is, what medications do we use to treat the relapsing forms of multiple sclerosis where there is a lot of acute inflammation, focal inflammatory lesions that are occurring? And then the final one is, what do you do with individuals who have a more progressive form of the disease where they're accruing disability slowly and gradually? Dr. Monteith: And what were some of the main points? Dr. Mowry: Dr. Okuda provided a really nice section on the treatment of acute relapses in multiple sclerosis, and it's important to understand what we talk about when we are saying "relapse". For people with MS, many symptoms can fluctuate and occur and then get better over time, and sometimes people with MS use the same term of "relapse" to describe those symptom fluctuations. As neurologists, when we're thinking about relapse, we're really trying to think about symptoms that can be attributed to new focal inflammatory events somewhere in the central nervous system. Typically, these are accompanied---if you were to get an MRI at the same time---by a new lesion or MS spot, as I like to call them, on MRI scan. And so, it's important to distinguish when somebody is talking about symptoms, whether they are true new symptoms that could be mapped to a place in the central nervous system. Because alternatively, a lot of people who've had attacks or relapses in the past can have what we call pseudo-relapses, and these are essentially recrudescence of old symptoms, typically in a similar pattern as what had occurred in the past. And these can be brought out by things like fever or infection, sometimes stress. And pseudo-relapses are not thought to be due to new development of immune system-induced injury and therefore would be less likely to respond to treatment; and in fact, treatment may be contraindicated for those events. We also talked a little bit in that article about how relapses are treated, talking about the use of high-dose steroids for true new relapses, but also kind of cautioning that those are not necessarily free of concerns, especially if you have a pseudo-relapse or there could be an infection going on. And that ultimately, the decision as to whether to treat a relapse really is a shared decision-making because it's thought that although the steroids can speed up recovery from a relapse, they may not have a major impact on ultimate recovery. And so, a lot of the shared decision-making comes in here because for a mild relapse, you might choose to forego a course of high-dose steroids.  Dr. Monteith: Daniel, any other main points?  Dr. Ontaneda: Yeah. On the side of treating relapses, I think one of the other things that probably has changed a lot, at least during the course of my training, is that in the past, whenever we had identified a relapse, as Dr. Mowry has clearly defined, we would typically treat with intravenous high-dose corticosteroids, typically with methylprednisolone. And that was kind of our go-to. We would either do it in an infusion center or we would set it up with home care. And I think one of the things that our field learned over, I would say, the last five or ten years is there's an abundance of studies that show that you can give that same dose of methylprednisolone. Rather than giving it IV, you can give it orally. No pun intended, as I tell my patients, a lot of pills to swallow because we use fifty-milligram prednisone pills, and they have to take 1,250 a day. The pharmacy always pushes back on that many pills, but really the advantage of being able to take steroids orally that way for three to five days is really, I think, one, better for people with MS because they can do it in the comfort of their own home, and two, I think also when you look at the costs associated with that treatment, it is the most cost-effective option. Dr. Monteith: And what are some of the latest developments that you're really excited about that weren't in the article?  Dr. Mowry: A lot of the article focused on the approach to treatment of people with what we've traditionally called relapsing/remitting multiple sclerosis. So, this is the kind of MS that traditionally presents with a relapse or an attack initially, although some of that nomenclature is changing, actually. And the article focused a lot on the strategies surrounding treatment of somebody with newly diagnosed relapsing MS, and thinking about this vast number of disease-modifying therapies that are available to people with MS and their clinicians, and how to think about the strategy with respect to largely centered around the efficacy class of the medication, whether people should take an approach of using a higher-efficacy therapy---meaning a medicine that in clinical trials was more likely on average to suppress relapses as well as new lesions---or whether there's still a good argument for the case of using an escalation approach, using some of the more modest efficacy medications that also probably in general have lower risks, monitoring for response to treatment and changing if the medication isn't working. And so, there's still a lot of debate in the field, I would say, even though many people have moved towards a one-size-fits-all kind of approach. I think there's still a lot of debate in the field about the evidence underlying that. And, you know, full disclosure, Dr. Ontaneda and I are each running parallel and very complementary clinical trial programs to address this very question, the results of which should be available within the next year, year and a half.  Dr. Monteith: Well, we can't wait that long. Give me some clinical pearls to how we initiate these modifying therapies. Like, what are the pearls that we need to have in our mind?  Dr. Ontaneda: Yeah. I think when we think about starting the disease-modifying therapy in an individual who has an active form of multiple sclerosis, I think, you know, one of the cornerstones I would say of making that decision is shared decision-making. I think we tend to sit down with the patient and analyze the data that we have at hand, what we know about their multiple sclerosis, and we use several factors to inform how likely we think their disease is gonna be active or potentially might not respond to the initial treatment you give. And we look heavily at the MRI. The MRI is really a useful marker because it shows us, one, how many lesions a person might have---both, you know, where those lesions are and also kind of the amount of lesions. Lesions, certainly, that are in the spinal cord, a very large burden of diseases. A lot of active lesions, which we determine by the presence of contrast-enhancing lesions, really helps us inform on disease severity. I would say that was our number one tool that we use to decide and help us decide how we think that person's MS is gonna do over time. And then the second thing that we put into the equation also is, you know, how well do we think this person is going to tolerate our medications? All our disease-modifying medications act through suppression of the immune system, and we know that that carries some risks associated with it. Some of those risks are stuff like infections. Some of those can be simple infections that really don't have major consequences, but some of them can be quite serious, including the need for hospitalizations or prolonged antibiotic treatment courses. And so, we also look at what, you know, the underlying risk of a person has for infection. This kind of is determined by, one, A, how many infections they've had up to date, and also how much disability they had. I would say in our average patient who when we see them, they're probably typically pretty young, in their twenties, thirties, forties, they typically don't have a lot of infectious risks. And therefore, I think there's kind of a move to saying, "Well, actually their risk of infections is quite low." And we put that together with, you know, also what the preference of the patient might want. So, do they prefer to take a pill, for example? Do they prefer a medication where they receive that via infusion every six months and they don't really have to think about it? There are some people that don't like going into a hospital, and they might prefer an injection type of those medications. And so, after a complex discussion of all those factors, we take into consideration how much risk the patient wants to take as well, and we come up with a rational choice of a couple of medication options. So, I think it's challenging sometimes because we have over two dozen medications. There's the risk of you saying, "There are these twenty-four medications, you can pick one." And I think our job as neurologists is to kind of pare those down, talk about, in a person like yourself, these are the two or three medications that I would recommend using. Why don't you review them? And then we bring them back, and we kind of make a final decision with, one of the key factors that I think is important to remind people is that you're gonna start this medication, and we are gonna monitor to make sure it's working. We're gonna monitor to make sure you're tolerating it well. And although it's an important, the first decision you make, I think one key theme that we tell people is, we can revise our strategy whenever we like. We just have to think about it and do it in a way that we think is gonna make sure that their MS is under the best control. And then we think about the ultimate goal of treatment, which, in multiple sclerosis, is the absence of any attacks and also the absence of any new lesions on MRI. And that's where whether you are offering more of the high-effective medications or more moderate- or low-efficacy medications, that's where there's a little bit of controversy still in our field, and that's what our trials are trying to answer.  Dr. Monteith: Excellent. So now we've selected a particular option- and I love those points with shared decision-making, using the MRI to guide and then kind of risk tolerance related to infection. But now a patient's still having relapses, and I know the goal is zero, but, you know, there's some margin. What are the pearls to advance to more high-efficacy therapies?  Dr. Mowry: Yeah, that's a great question. Dr. Ontaneda in the article actually talked about the literature surrounding monitoring for breakthrough disease and when to say this much is too much, and there's actually not a definite right answer. It's clear that more active disease early in the course is probably more of concern than, say, developing, you know, a new spot in your fifties or something to that effect. So, different people have different thresholds. I know at our center, we tend to be pretty on top of making changes for breakthrough disease. So, what we typically do is reimage people about six months after they start a medication to establish a new baseline. And sometimes, because of delays in starting or because the medications take a while to kick in, there might be a new spot or two. So, if that's the case, I really only get concerned if the spots are also taking up the dye or enhancing to indicate they're really quite recent, and I think, "Ugh, that's not something I'd like to see six months after starting a medication." And so that otherwise is sort of the reference scan, moving forward, to evaluate the medication, and I have a very low threshold for changing, particularly if somebody is on a moderate-efficacy therapy. To me, I think, well, our goal of trying the moderate efficacy therapy is essentially to see if we could get away with a medicine that is probably, on average, safer and that will still work for your MS. But if the answer is no, I personally don't like to stick around too much on them. One caveat I would say is that if somebody develops what appears to be a new lesion or spot on higher-efficacy therapy, before presuming that that new area of activity is a definite new MS event, I always like to rethink carefully, did I get the diagnosis correct? Or could this be an early infection such as, you know, progressive multifocal leukoencephalopathy in people on natalizumab in particular? Because I see breakthrough activity so rarely in people on higher-efficacy therapies that I just like to rethink my diagnosis and the differential prior to making switches to, typically, another higher-efficacy therapy in that case. But that, again, is a little bit of shared decision-making. It's sometimes contextual. If a person is using a self-administered medication and they have a little breakthrough, sometimes you can solicit some history, saying, "Oh, I actually kind of stopped taking it for a few weeks because something was going on, and I really want to retry." And that's very reasonable as well. Dan, do you have any other thoughts?  Dr. Ontaneda: No, I think I agree. That's really close to how I practice myself as well, and the majority of people at my center. I think that we are learning that when you start a treatment, many times---depending on how deeply you look---you can find evidence of ongoing disease, and that's something that we struggle with. It's almost like we have tools to treat inflammation in terms of new MS lesions and new relapses. And so, when those are present, it's pretty clear that you probably have to switch medication. I think a slightly trickier issue is when, for example, you have a person who might be stable. They don't have an attack. But you notice that they're worsening, and they tell you they're worsening. I think our ability and tools for that is a little bit harder, and we recognize that that can actually happen fairly early in the disease. And that's why we're trying to rethink this mantra that we've had for many years, where we kind of divide MS up into relapsing and progressive, and we see people develop progressive MS 10 to 15 years after they've had a relapsing form of the disease. So, I think that's just a reality of clinical practice. And we don't have as many tools to treat that gradual worsening, which is kind of what the rest of our article spent some time talking about. Dr. Monteith: You've also written about the clinical trial long-term extension studies. And what are the few points that you take away from the emergence of these types of publications over the past few years? Dr. Mowry: Yeah, well, long-term extension studies can be really helpful to understand whether the findings that are evidenced during the randomized portion of trials themselves continue into a longer term. And for people with MS, understanding these data can be really helpful because, particularly when we're looking for impact of a given treatment or a strategy on disability worsening, often it takes longer than the short-term portion of the trial to truly understand if the medication or strategy has an impact on insidious worsening that Dan is speaking about. Many trials have demonstrated a short-term benefit, but we think a lot of times that benefit is probably because of the reduction in relapses, which sometimes leave a permanent mark on neurologic function. But the extension studies are trying to understand a little bit more about whether the effect on disability worsening is sustained, and also to look a little bit more deeply at long-term safety, especially when it comes to medications that do increase the risk of infection. The caveats, though, in interpreting those types of studies are that people drop out, and so probably the people who drop out of those studies are really different. They may be either less disabled and they think, "Oh, you know, I'm done. I feel good." Or potentially more disabled and they think, "Ugh, I have more things to do I've got to take care of. What's going on?" And so that kind of dropout can produce some bias in interpreting the results. Dan, any other thoughts?  Dr. Ontaneda: No, I think that's spot on. I mean, I think that when we're trying to decide on what general philosophy to use, right? Like, you're seeing a patient for the first time. They've recently been diagnosed with MS, and you have... you know, I kind of bin them into three options. You can start a low-efficacy, a moderate, or a high-efficacy medication. And the first piece of information you could use is clinical trials, and Dr Mowry very clearly identified why some of that data might be a little bit biased and isn't, you know, completely applicable to the patient who's in front of you. The second thing that we might look at is observational data, and there's a wealth of observational data that shows that, in general, people on higher-efficacy medications tend to do better over time. But one of the challenges we have is that there's always biases related to those observational study designs. And so, I think you have to interpret them with a little bit of caution because there are reasons people start specific medications in people. And when you look at them in a purely observational study, even if you do some fancy way of addressing those biases, such as propensity, there always is the possibility of some residual bias. You know, that's part of the reason why we're doing the trials that Dr Mowry described, because we really need kind of long-term evidence to show that these medications actually can affect disability ten, twelve years after started. And I think pragmatic clinical trials, like the ones we're running, are really gonna be the key to answer those questions. We all have our favorite approaches right now, but I think that the data to actually demonstrate what's best for people with MS is really needed.  Dr. Monteith: Great, and there's so much in this article. I mean, we didn't even touch on radiological isolated syndrome, monitoring MS therapeutically, and treatment of progressive MS. Any final take-home points?  Dr. Ontaneda: Yeah. Maybe I will touch a little bit on the side of progressive MS, because it has been, you know, the MS that we historically have not been able to treat as much. So, we described there's over two dozen therapies approved for relapsing forms of MS. For purely progressive forms of MS that don't have any evidence of activity, we really only have one approved therapy, and it appears that that therapy actually does work through active inflammation anyway. And in the article, we highlighted examples of studies that have been negative, but also some recent examples of studies that have been positive, specifically with a new class of medication called BTKI, or Bruton tyrosine kinase inhibitors. We just recently heard of a second molecule that also had positive results in this realm. So, we're excited that, you know, in the next four to five years-  Dr. Monteith: I'm sorry. Can you just go ahead and say what that molecule...You're leaving people hanging.  Dr. Ontaneda: One molecule is tolebrutinib, which already has a positive study in secondary progressive MS in individuals without activity. And then the second compound that has been studied with positive trial results, we only have summary results from that, is a medication called fenobrutinib. And we think these two compounds that are part of a single class, the hope is that maybe they can address some of that gradual worsening that occurs in MS. And then the question comes whether we should use those from the get-go or if we should just use them later. So, a whole sort of variety of different questions. But I think important to call out for clinicians that this area where we had no available treatments for so many years might be changing.  Dr. Monteith: Well, thank you both. I really loved this conversation. I learned a lot listening to both of you, and I look forward to your clinical trial results.  Dr. Mowry: Thank you so much for having us. Dr. Ontaneda: Thanks so much. It was our pleasure.

Transcript

Although rare, recognizing NMOSD is crucial for improving patient outcomes through correct diagnostic and treatment approaches. Reports of atypical forms and increasing knowledge of clinical, imaging, and laboratory-specific features are fundamental for the accurate recognition of this condition. Research on targeted therapies and biomarkers measuring and predicting disease activity will improve NMOSD management. In this episode, Gordon Smith, MD, FAAN, speaks with Sara Mariotto, MD, PhD, coauthor of the article "Neuromyelitis Optica Spectrum Disorder" in the Continuum® April 2026 Multiple Sclerosis and Related Disorders issue. Dr. Smith is a Continuum® Audio interviewer and a professor and chair of neurology at Kenneth and Dianne Wright Distinguished Chair in Clinical and Translational Research at Virginia Commonwealth University in Richmond, Virginia. Dr. Mariotto is a neurologist in the Neurology Unit in the Department of Neurosciences, Biomedicine, and Movement Sciences at the University of Verona in Verona, Italy.

Today, I'm interviewing Dr Sara Mariotto about her article on neuromyelitis optica spectrum disorder or NMOSD, which she wrote with Dr Romain Marignier. This article appears in the April 2026 Continuum issue on multiple sclerosis. Sara, welcome to the podcast, and maybe you can start by introducing yourself to our audience.  Dr Mariotto: Yes. Thanks, Gordon. I'm Sara Mariotto. I'm a neurologist, and I work at the Neurology Unit, University of Verona, where I do both clinical diagnosis and research into neuroimmunology---so, in particular, autoimmune encephalitis, NMOSD, and MOGAD.  Dr Smith: Well, this is a super exciting area. Whenever I hear about NMOSD, I think of one specific patient I had, and I always think of her when I come across something like your article, which is really fantastic. So, before we dive into the details, I wonder if maybe you can just explain to our listeners who aren't up to speed on what NMOSD is, what the disorder is, and maybe why it's so important that all of our listeners learn how to recognize it quickly and get people started on therapy.  Dr Mariotto: Yes, sure. So, neuromyelitis optica is an inflammatory autoimmune CNS disorder usually associated with aquaporin-4 antibodies, although there are a few cases, around 10%, who can be antibody-negative. And I think it's very much important to have in mind this disease and recognize it because it can be severe, as you pointed out; can present with very severe optic neuritis, myelitis, the brain stem, or area postrema syndrome. So, it can be really severe, affect quite young people around 40 years of age---although it can affect also the pediatric population and elderly people---and, importantly, it can be treated. It's very much important to treat this patient in the acute stage very quickly with steroids or plasma exchange in addition, and then to start a chronic treatment. So, we have treatment for this condition. So, it's very much important to, to recognize it quickly and treat the patient properly.  Dr Smith: So, I wonder if we can talk a little bit about the diagnostic criteria and boundaries of NMOSD, right? So, someone who comes in with bilateral op- severe long segment optic neuritis or long segment myelitis, we think about it. But what are the boundaries? Should we be looking for this, for instance, in someone who comes in with a unilateral optic neuritis or looks like typical multiple sclerosis? Is it important to get aquaporin-4 antibodies in those patients? What do the diagnostic criteria say about this?  Dr Mariotto: So, I wouldn't test aquaporin-4 antibodies in all patients with demyelinating conditions because although aquaporin-4 antibody assay is very specific, as for all assay and all antibody testing---also for MOG antibodies, for example---some false positive results can come out. So, I would suggest to test aquaporin-4 antibodies not in typical MS cases but in those who could be suggestive for not being MS, so in all those cases with atypical optic neuritis and myelitis or other syndromes. For those cases, it's important to test aquaporin-4 antibodies, but I wouldn't test them in all typical, classical MS cases. As I said, it's quite specific, the assay, so it's uncommon to have false positive results, but it can be.  Dr Smith: Serum, CSF, both?  Dr Mariotto: So, for aquaporin-4 antibodies, they're usually present in serum. They can be positive also in the CSF. And there are a few reports of isolated CSF positivity. But if we analyze larger samples volume, then it becomes clear that isolated CSF positivity is so, so rare that it's not recommended to test them in the CSF when serum is negative. So, for aquaporin-4 antibodies, the recommended matrix of testing is serum, which is different for MOG, which is not the topic of our article but is important to mention because MOG antibodies should be tested in serum and CSF. But aquaporin-4, I would recommend to test serum.  Dr Smith: What are the boundaries between MOGAD and NMOSD? And you talked about the differential testing of antibodies, which I was going to ask about. But when should we think of NMOSD relative to MOG? Dr Mariotto: Yeah. There are aspects which are the one mentioned in the criteria, highly suggestive for NMOSD. But the clinical spectrum can be similar to that of MOGAD. Usually, although there are some clinical aspect---like, for example cortical encephalitis or ADEM, which is more typical for MOGAD, or others like area postrema syndrome, which are more typical of NMOSD. The spectrum can be similar among the two conditions, so that's why in our clinical experience, usually they ask both aquaporin-4 and MOG antibodies in patients. It's- for experts, it can be easy to differentiate the two conditions, but for nonexperts can not be so easy.  Dr Smith: Can you define area postrema syndrome? I think not all of our listeners see that every day.  Dr Mariotto: Yeah, sure. This is a syndrome which is highly suggestive of NMOSD. That's why I mention it. And it's characterized by nausea, vomiting, hiccups are known as the syndrome. And it is very, very suggestive because of the expression of aquaporin-4 in that area of NMOSD. That's why I strongly recommend for all patients who comes out to have this syndrome to test for aquaporin-4 antibodies. MOGAD is hardly ever positive for that, so I think that whenever you see a patient with that syndrome, you should think about NMOSD.  Dr Smith: I'm just curious, aquaporin-4 is a water channel, which is kind of an interesting concept. Our conversation, I really want to make sure we give clinically important information to folks, but it's so curious to me at least, how does this actually result in a inflammatory demyelinating syndrome? For a simple neuromuscular guy, what's the immunopathogenesis of this?  Dr Mariotto: Yeah, the immunopathogenesis is quite complicated, as in all CNS disorders. And of course, aquaporin-4 antibodies are the main focus, but they are not the only one. As you said, aquaporin-4 antibodies have a target, this water channel, which is at the basis of the disease, and they are produced by the interplay between T cells, B cells, and plasma cells. But then also eosinophils, macrophages, cytokines, and chemokines are involved, enter the CNS, and then another important component is complement, which is highly activated in this disease. At the end, we have astrocyte damage because astrocytes are the main target of the disease, but also axon and myelin are involved. So, it's a quite complex pathogenesis based on the antibodies, but not only on that.  Dr Smith: And this will become important when we start talking about treatment. There seems to be a recurring theme of long segment demyelination, right? Optic neuritis is typically a large percentage of the length of the optic nerve, and obviously the myelitis se- more than three segments. Do you see other long segment areas of CNS demyelination, corpus callosum or things like that? Any ideas why that is, if that's true?  Dr Mariotto: Of note, this is quite interesting because usually when we have NMOSD, we have a longitudinal involvement, especially of the optic nerve and spinal cord, while brain lesions are quite different. Like, we usually do not have the typical Dawsen fingers-like lesions that we have in MS, for example, or the classical periventricular or subcortical extensive lesions that we can see and we have in mind when we think about MS. In some cases with NMOSD, the brain is completely negative, so we do not see anything. And Dawsen lesion's quite suggestive of NMOSD. So, you're right. I mean, this is related partially to the expression of aquaporin-4, and that's why we have this typical involvement also for area postrema, for example, and maybe also our other examples of clinical aspect that we can see in these conditions. But it's basically linked with the expression of aquaporin-4, which is the main target of the disease. And that's why usually the brain doesn't show so much involvement as we can see in MS, for example.  Dr Smith: I was actually really interested in some of the unusual manifestations or phenotypes, and I don't want to get into arcadia, really, but which of these should our listeners be familiar with that would really suggest that they should be thinking about NMOSD beyond the area postrema and other features that we've already talked about that are part of the core criteria?  Dr Mariotto: Yeah. I mean, I think that the encephalic syndromes or also ADEM, which is most typical of MOGAD but can be observed also in NMOSD or PRES, for example, are syndromes that can be considered in patients with NMOSD. There are the typical ones, which are the ones showed in the criteria, but whenever we have a brainstem involvement or, like, these encephalic syndromes or also PRES, we should think about NMOSD also.  Dr Smith: Another area I was interested in are red flags. In your article, you talk about red flags that might suggest an alternative diagnosis, right? And then this presumably is particularly important in seronegative patients, which 10% is not a reasonably high number, I suppose. What are red flags we should be thinking about for some other diagnosis?  Dr Mariotto: Yeah. I would here mention two very important red flags. The first one is a very hyperacute onset. Usually these conditions, these inflammatory conditions have a subacute onset, so whenever you have a very, very acute onset, you should think about something else. This can occur sometimes also in NMOSD, but hardly ever occur. Like, a very acute myelitis, the first thing we should think about is a vascular origin, for example, with a lot of pain and not about NMOSD, although sometimes the differential diagnosis is not so easy. The second thing is a progression independently of relapses, which hardly ever occur in NMOSD. Usually in NMOSD, we have the onset, and then we have a relapsing disease course. That's why we have to treat patients always and not to stop treatment. But we do not have progression in the meanwhile, while we can have, for example, this in MS. Same thing is for MOGAD. So, these are two things that I think is very much important to keep in mind.  Dr Smith: I want to pivot to talk about treatment because that's been super exciting. But rumor has it there are new diagnostic criteria coming for NMOSD in the next year. I bet you know a bit about those. Can you give our listeners any indication about kind of where the puck is going on this? Not so much what the criteria are specifically, but what sort of diagnostic challenges are the new criteria going to help us with once they come out?  Dr Mariotto: Yeah. So basically, we are working on that, so you will read them in the next future. This is the good point of the conversation on the new criteria. And we work a lot on the definition, on the new definition and nomenclature of NMOSD; on the definition of seronegative NMOSD, which is also quite tricky; and then on the assay we should use to test aquaporin-4 antibodies, and also on potentially new syndromes which should be included into the main feature of the disease. But hopefully you will read about this very soon.  Dr Smith: Looking forward to it. And Continuum Audio listeners, you heard it here first, so thank you. Let's pivot to treatment. This has been super exciting, and I wonder if the way to approach this is to start with acute management and then sort of chronic management. Would that make sense?  Dr Mariotto: Sure.  Dr Smith: Let's say I go on service on Friday, and I have a patient who comes in with positive aquaporin-4 and bilateral optic neuritis. What's the acute approach to managing that patient?  Dr Mariotto: So, the first approach is to administer intravenous steroids, but I would not wait to escalate to plasma exchange. There is quite good evidence that we should treat the patient with additional plasma exchange very quickly, and every day of delay of plasma exchange can cause increased disability. So, we should treat patients with steroids first, and then if we are not satisfied by the recovery, soon start with a plasma exchange. There is also some evidence, although less, for IVIG, but it's important to try to treat them very quickly, even if it's Friday, you know, there is the weekend and so on. But I think it's very much important to start with steroids after excluding other infectious causes or so on, and then to start quickly with plasma exchange. The main problem could be that we do not have the results of the antibody yet.  Dr Smith: Right. So, let me ask that question. You know, let's say my patient comes in on Friday, and clinical syndrome that really looks like NMOSD, and we're waiting for the aquaporin-4. There are many places where it's hard to get plasma exchange over weekends. And so, in that setting, are you better off doing the steroids over the weekend then PLEX on Monday, or should we just give IVIG because maybe it's as good as PLEX? What's your advice there? I'm trying to get ready for Friday because I know one's coming in.  Dr Mariotto: That's true, that's true. Usually they come on Friday or Saturday. I think it's acceptable to have three days of steroids and see how the patient improves, and then after three days to start with plasma exchange. Actually, we have a very good improvement if we start between three and five days after onset. So, I think waiting for three days is acceptable just because we can see if the steroids work properly or not, and then we can quickly start to plasma exchange. But I would not wait, like, 10 days, you know, before starting with a plasma exchange, and I would not wait for antibody results.  Dr Smith: Got it. Super helpful. And I'm actually not joking around, I learned recently that I have a reputation among our residents for having lots of optic neuritis when I'm on service, which I think is sort of karmic justice for being a peripheral nerve expert. But let me ask another question. So, let's say we do that, and the patient gets three or five days of pulse methylprednisolone and five courses of PLEX, and they're not doing well. Do you then just move right along into another agent B cell depletion therapy? I mean, what's your next step in escalation in the acute setting?  Dr Mariotto: I would for sure start to, as you said, with steroids, plasma exchange, and in case IVIG, and then quickly move to chronic treatment. And for patients who are not recovering well, I would think of something which has a quick effect so we can really start treating patients very quickly. There are different options. And all over the world, there are different rules for using immunosuppression in NMOSD. Like in Italy, for example, it's different from US or other countries, Germany, for example. There are different approved treatments and different rules of using them before or after rituximab, for example. We all know that there are treatments approved for NMOSD all over the world. But in some countries, like for example in Italy, we should use rituximab first, and then if it doesn't work, escalate to the approved treatment. I know in the US it's different. But anyway, for a patient who does not improve quickly, I would start with something which has a quick effect on the disease.  Dr Smith: And then rituximab versus inebilizumab, you know, CD20, CD19, what's your advice there? Is one preferable to the other, you know, if we have options to do either?  Dr Mariotto: Yeah. So, between rituximab and inebilizumab, we know that the target, well, is different, but is anyway B cells, so CD19 and CD20. With CD19, we can affect both plasma blast, plasma cells, and B cells. That's why the target is broader. And of note, this is an approved drug, while rituximab is, in most countries, used as off-label treatment.  Dr Smith: So inebilizumab would probably be preferable if we're able to do that.  Dr Mariotto: Unfortunately, there are not so many studies comparing rituximab with the approved drug, which is, of course, a pity, but that's the case. While we have clinical trials for all the approved drugs, and although the trials were designed differently, as we mentioned in the Continuum paper, we can argue something of the comparison between the approved drugs. But it is not so clear the comparison between rituximab and the new drugs, which is also something that we should work on.  Dr Smith: And then for chronic suppressive management, what other options are there?  Dr Mariotto: So, in addition to B cells, target can be interleukin-6, as we know with tocilizumab or satralizumab, and then complement with eculizumab. These drugs are both based on the pathogenesis of the disease. That's why we also discuss it in the paper, which shows a clear involvement of complement, and among cytokines of interleukin-6. So, targeting these made clear that could improve the disease quite well, and that's why they designed some clinical trials on these drugs, which are now approved, as we said, for NMOSD.  Dr Smith: Wow, so many options, and a lot of questions, but limited time. Let me just ask a couple of more. I see a lot of myasthenia patients, and there's a lot of variability, as you know, in patients with myasthenia, the extent to which complement is an important mechanism versus other, you know, important mechanisms. To what extent is response to a complement inhibitor kind of uniform across NMOSD? Or there's some patients who just don't respond to a complement inhibitor and others that respond really well. And then just, I'll just give my second question out is, you know, what about combination therapies for patients who have particularly challenging NMOSD?  Dr Mariotto: So usually these patients have a terrific response to complement inhibitors, and this is also shown by the clinical trials where we saw how eculizumab have a very impressive effect on the disease. And also, maybe this is also your experience, a very quick effect. So that's why there are also thoughts on using it in a very acute stage of the disease. That was what I was thinking about before. But then it has a very huge effect on complement, which is a major factor involved in the pathogenesis of NMOSD also in the chronic disease stage, and that's what also we see from clinical trials. Usually, we prefer to switch treatment from one to another and not to combine them. Of course, in very difficult cases, this can be considered, but the recommendation is to switch from one of these approved drugs to the other, or from rituximab to one of the approved drugs, and try to find out the best for our patient before combining them. Dr Smith: The complement inhibitor trials are breathtaking, at least for me. If I'm trying to convince students to go into neurology, I'll say, "Take a look at that paper," because anyone who claims that we're "diagnose and adios" is so wrong. It's so exciting. So, at a high level, this must have fundamentally changed outcomes for patients. I mean, it's still a difficult disease, but what is the kind of prognosis for that patient I described who comes in, gets the therapy you talked about? What does their long-term outcome look like in this modern therapeutic environment? Dr Mariotto: So, NMOSD is almost always a relapsing disease. That's why, as we mentioned, we have to treat patients always. But the prognosis changes a lot since we were also able to use all these drugs for the disease. So, the prognosis changes if we recognize it properly and early, and if we treat NMOSD properly with immunosuppressives. So, whatever we choose it's important to start it quickly, and this is the only way that we have to improve the prognosis of this disease. We have very active cases, but we have also cases who responds quite well to this immunosuppressive treatment, since now we have, as mentioned, these ones which are very impressive and show incredible results. So, the prognosis of the disease change in the last year, thanks also to the improvement of the diagnosis and of the treatment choices for the disease.  Dr Smith: I'm just... I- maybe my last question, you know, just at a personal level, not only for you as an expert who's caring for these patients, but in the patient community, this must have been a pretty exciting period of time, right? I mean, these, these drugs are coming fast and furious, and what a change. What's the kind of zeitgeist in the community, both your professional community and amongst the patient community about where we are? Dr Mariotto: Yeah, you're right. The last years were defined the years of NMOSD and also MOGAD because we had finally approved drugs which is relevant for all the disease that we treat and changed the landscape of the disease for clinicians, but also for patients. And we have more than one, as we said, so we have more options that we can also discuss with patients to try to choose the best one in terms of activity, but also route of administration or time. Some years ago, we just had rituximab, which is not approved in most of the countries, and now we have different approved drugs. And we improved the diagnosis of the disease thanks to the availability of live cell-based assay. And then we are working a lot also on biomarkers like GFAP, for example, which has been shown to be a very attractive biomarker able to mark disease activity and maybe also prognosis on this disease. So, you're right. I mean, in the last years, the landscape of NMOSD changed a lot.  Dr Smith: Sara, thank you so much for talking with me. I could keep going for another half an hour, but I would be in trouble with my editor, so I think we probably need to wrap it up. But thank you so much. This has been very informative.  Dr Mariotto: My pleasure. Dr Smith: Mine too. Thank you.

Familiarity with the clinical, MRI, CSF, and serologic features of MOGAD can help neurologists recognize this condition in clinical practice. Awareness of the utility and pitfalls of the MOG antibody test is critical. The current therapeutic approach is guided by retrospective studies and the application of immunotherapies used in other autoimmune neurologic disorders. In this episode, Gordon Smith, MD, FAAN, speaks with Eoin P. Flanagan, MBBCh, coauthor of the article "Myelin Oligodendrocyte Glycoprotein Antibody–Associated Disease" in the Continuum® April 2026 Multiple Sclerosis and Related Disorders issue. Dr. Smith is a Continuum® Audio interviewer and a professor and chair of neurology at Kenneth and Dianne Wright Distinguished Chair in Clinical and Translational Research at Virginia Commonwealth University in Richmond, Virginia.

Dr Smith: This is Dr Gordon Smith. Today I'm interviewing Dr Eoin Flanagan about his article on myelin oligodendrocyte glycoprotein associated disease, or MOGAD, which appears in the April 2026 Continuum issue on multiple sclerosis and related disorders. Eoin, welcome to the podcast, and please introduce yourself to our audience.  Dr Flanagan: Yeah, thanks so much. I'm Eoin Flanagan. I'm a neurologist at the Mayo Clinic. I'm originally from Ireland. I work in the neuroimmunology lab at the Mayo Clinic, and work and see patients with MS, MOG, and autoimmune disorders here in Rochester, Minnesota.  Dr Smith: Your article is super interesting, I think, and this has been a really rapidly evolving area over the last, you know, many years. We have many more antibodies, and MOG is something that's been around for a while, but we've certainly learned a lot more about it. This is a topic that I think will be familiar to most of our listeners, but I wonder if maybe you can just begin by laying the foundation. Like, what is MOG? What's its typical presentation?   Dr Flanagan: So, MOG is a protein on the surface of the oligodendrocyte or its CNS myelin, and it was always of interest as a potential antibody target, and initially it was investigated in multiple sclerosis. But subsequently, we recognized that the antibodies to MOG have a specific syndrome, of which about a quarter of patients are pediatric and then the remainder are adults. And they can present with a variety of syndromes, probably most commonly optic neuritis, but also acute disseminated encephalomyelitis, or ADEM. Transverse myelitis can also occur, and then some other unusual brain and brainstem cerebellar syndromes can also occur.   Dr Smith: I was really impressed in the very broad phenotypic spectrum of MOG. We'll talk more about that, of course. But I wonder if maybe you can tell us when we should be ordering MOG antibody? Given this broad variability, does anyone who has a CNS demyelinating disease need a MOG assay, only specific phenotypes? What guidance do you have for our listeners?   Dr Flanagan: Yeah. It's a great question. So, I think you have to be a little bit careful because the MOG antibody test is a little bit sticky. So sometimes we can see some low-positive false positives. So, we don't wanna order it in every single patient with classical MS. So, I suppose we'll start with who not to order it in. I think it's also a very optic nerve- and optic neuritis-central disease, so I think you really need to be considering this in a patient with optic neuritis who does not have lesions in the brain suggestive of multiple sclerosis. And then we think about some of the features: if the lesion, the enhancement along the optic nerve is long, if it's bilateral, if there's a lot of optic disc edema accompanying that, we tend to think about MOG antibodies. And then children with demyelinating disease, MOG is over-represented in that cohort, so it accounts for about a third of those. So, if you have a child with CNS demyelinating disease, particularly if they're under twelve, with ADEM presentations or other presentations, you probably want to be ordering the MOG antibody test. And then a longitudinally extensive transverse myelitis in adults, certain types of cerebral phenotypes that we can get into, you would want to consider ordering MOG antibodies too.   Dr Smith: Now, you point out in the article that it's really important that laboratories use the cell-based assay for MOG as opposed to an ELISA, for instance. Is this something folks need to be very attentive to, or are all of the commercial laboratories now using a cell-based assay?   Dr Flanagan: Yeah. I think all of the commercial labs are using cell-based assays, so we don't really get into much of an issue. There are some differences between serum and CSF, so really, serum is the optimal sample to order. There is also some differences between the live cell-based assay and the fixed cell-based assay, where the live cell-based assay may have some advantages in terms of sensitivity. And then CSF is kind of still under evaluation about its role in the condition. So in general, it's a serum test. And then we have to remember that the antibody tends to be highest at the onset, and then it goes down over time. So, if you delay your testing or you're testing a patient long after the condition, it can go negative, for example. So it tends to be highest both around the relapses and particularly at the onset of the condition.   Dr Smith: You mentioned earlier that the test is sticky, which I take to mean that there is some risk for low-titer false positives. How do you navigate that situation? When should we be suspicious about a false positive?   Dr Flanagan: Yeah. I think there's some very useful features that can help you. You know, the main differential diagnosis is going to be multiple sclerosis, particularly in the US, in regions of the northern US where MS is particularly common. So, you really wanna be making sure that if you get a positive result, low positive, that it's not multiple sclerosis. And some of the best discriminating features are CSF oligoclonal bands. They're about 85% in MS and about 15% in MOG, so an easy number to remember, 85 and 15. And then the lesions in MOG, the brain lesions, tend to disappear over time. So, if you have the advantage of that follow-up MRI a year down the line, about 70% of lesions in MOGAD will resolve, while in MS, as we know, the term means multiple scars, so the MS lesions tend to persist over time. So, they are two quite useful features that can help discriminate.   Dr Smith: And how about specific phenotypes or areas of involvement or imaging abnormalities that suggest MOG? One of the things I found really interesting in your article is there are a host of different syndromes that I think had largely been previously described, many of them, that became clear later that these were really tied to MOG antibodies. Presumably, that's helpful in interpreting the antibody assay in that patients who have, perhaps, a borderline low titer, for instance, but have a very typical phenotype are more likely to have MOG than those who have a more clearly MS-type phenotype.   Dr Flanagan: Yeah, absolutely right. Yes. So, there's certain phenotypes that we don't tend to see with MS. The acute disseminated encephalomyelitis, or ADEM, is one that's particularly common in children. And about half of people that have ADEM will be positive for the MOG antibody. So that's a syndrome you need to look out for, which would be often in children, encephalopathy, and they would have multifocal white matter lesions, sometimes involving the gray matter. A second syndrome that was an interesting discovery from a Japanese group was this unilateral cerebral cortical encephalitis, where patients can have this swelling and T2 hyperintensity, often just on one side of the brain. And it's in the cortex, and some of those patients won't have any white matter lesions. And in that situation, it's important to order the MOG antibody, and that seems to be a specific phenotype of MOGAD. But sometimes people don't think about it because the white matter is not involved. So, if you see these patients, they often present with seizures, sometimes they even have fever accompanied by it. And if you see those patients and see this radiological feature, then you really want to consider ordering the MOG antibody too.   Dr Smith: Yeah, I found that really interesting. And I- actually, my next question is perhaps a good follow-up on that, is, what are the diagnostic pitfalls? You give a lot of examples of situations and I think some cases where it's easy to get tripped up and misdiagnose someone who has MOG with another fairly common neurological problem.   Dr Flanagan: Yeah, I think some of the things that can help you when you're determining if the MOG is a true positive or false positive is the level of the antibodies. The super high titers, if it's a clear positive or very strong positive, the likelihood is that that is much more likely to be MOGAD than those low positives just above the cutoff. So that can be useful to help you discriminate from false positives. Those lesions, again, if all the lesions persist over time, that's going to be more suggestive of multiple sclerosis. Other diagnostic pitfalls, I suppose, if it's a syndrome that's not really associated with MOG, like peripheral neuropathy or other syndromes where we'll see some case reports, but usually I would be very cautious about those kind of presentations. So usually, having the antibody at a high level, and then also if they've had other symptoms suggestive of MOGAD, like if a patient has had recurrent optic neuritis and then they have an unusual brain syndrome, or they start out with an unusual brain syndrome and then have recurrent optic neuritis. You know, there are situations that make it more likely if they're having other typical phenotypes of the MOGAD where we can kind of expand the spectrum, but we have to be careful.   Dr Smith: I was really curious about the dynamic imaging findings. And you point this out both in terms of the resolution of imaging findings, but also in that patients who have an acute MOG syndrome often have very rapid evolution of the imaging abnormalities. I'm just curious, you know, why is that, and what do you make of it? Does it have a mechanistic implication, do you think?   Dr Flanagan: I don't think we know for sure. I think there's probably a lot more happening than we see on MRIs sometimes. What sometimes can happen in about 10% of patients is the initial MRI can be normal. We don't tend to see that with multiple sclerosis or NMOSD. Then what we see is it evolving over time. So, at that time, if you do a CSF, you'll often see inflammation, but we don't see the lesions. Now, that might be because the MRI is not very good at picking up cortical involvement. That can be difficult to see in MRI. Or there could be other factors. It could be a functional effect on the MOG but without frank demyelination yet, for example. Or there could be edema that you- myelin edema that you can't see as a lesion yet on MRI. But we do see that if you repeat the MRI, sometimes it'll change a lot. So, you may go from one or two lesions on the first MRI to twenty lesions on the second MRI a week later. So, it does tend to change a lot. And then over time, those lesions also resolve. So, what I say is if it's a very suspicious situation---like a child comes in with new-onset encephalitis, has inflammatory CSF---you might wanna consider repeating that MRI down the line and seeing if it's changing. And then over time, you know, a repeat MRI a year after the onset when there's brain or spinal cord lesions can be very helpful just to make sure you're on the right track, because lots of those lesions will then disappear, and that's a very clear discriminator from multiple sclerosis.   Dr Smith: Yeah, thanks. I mean, I was wondering the same thing about whether that particular feature might imply, you know, a functional abnormality as opposed to more of a structural abnormality. So probably a lot more to learn as we move forward. There are now consensus diagnostic criteria that were published a couple of years ago. I think you've already touched on kind of the general approach, but do you want to speak to those? I found your summary pretty helpful.   Dr Flanagan: Yeah, I think that those criteria are quite useful. They have three main parts to them. The first part is having a characteristic clinical syndrome. So, we talked about ADEM, we talked about cerebral cortical encephalitis, transverse myelitis that's often longitudinally extensive, and optic neuritis being the main syndromes, but sometimes other brainstem or cerebellar involvement can be seen. And then the second part is having a positive MOG antibody. And then there's some caveats there. So, if you have a high positive, then you don't really need any additional supportive criteria. On the other hand, if you're low positive, to get at those sticky antibodies that make sure it's not a false positive, you need some additional supportive clinical or MRI criteria. Or if you're only positive in CSF, you need that additional criteria. You also need to be negative for the aquaporin-4 antibody, because they can overlap clinically. And some of those supportive criteria are things that we talked about a little bit earlier, longer lesions within the optic nerve, bilateral involvement, involvement of the nerve sheath or optic disc edema. This is a situation, MOG antibody disease, where your fundoscope is useful and looking in the back of the eye and seeing swelling, because we don't tend to see that quite as often. It's less common in multiple sclerosis, but we often see prominent edema in MOGAD. And then in the spinal cord, the lesions tend to be central in the cord. Sometimes they form this H sign where it's restricted to the gray matter, and they tend to be longer, sometimes involving the conus. Patients will often have neurogenic bowel or bladder. And then in the brain, deep gray involvement, those large lesions along the cortex with swelling are some of the typical features. And then the final step is exclusion of another diagnosis. Just like with any test that we do in neurology, our final step is going to be to put that into context. So that's just a normal thing that we will always do when we get a group of test results back that we don't know what it means. We have to put it into context. So, make sure it's not multiple sclerosis, everything else does not look like multiple sclerosis, and then you can be on your way to make a diagnosis.   Dr Smith: Definitely encourage listeners to read your article. I guess I say that with every time I- or with everyone I talk to for Continuum Audio, but the images are really fantastic and the cases are fantastic. So, everything you've described is well-illustrated, including really nice schematic sort of diagrams that help differentiate NMO from MOG and MS. So, if you like MRI scans and good imaging frameworks, then this is the article for you.   Dr Flanagan: I think that's true, and the other thing is that the imaging is quite helpful because it takes a while for that antibody to come back. We're lucky at Mayo Clinic, if you work here, it, it comes back faster for you. But for many places, that time of sending it in, so a lot of times you don't know right away. So, looking at scrutinizing that MRI can be very helpful to guide you on your way and to know what you're dealing with and how to approach both the acute treatment and plans to have potentially a steroid taper after the acute treatment and those kind of things that can help guide you in that regard.   Dr Smith: Yeah. So, let's talk about treatment. You know, what's your approach to treating a patient who has an acute demyelinating syndrome related to MOG?   Dr Flanagan: So similar to other things, MOG is very steroid responsive. So, we use high-dose IV methylprednisolone in adults. That would be one gram IV for five days. And then we also will sometimes use oral steroids, twelve hundred and fifty milligrams. That's a bit of a hassle because it's twenty-five fifty-milligram tablets, it doesn't come in a larger tablet version. But it's very helpful to patients because they can get started on it right away. You don't have to set up an infusion center. So, we have used those oral steroids often in people who don't have access to an infusion center, are not in the hospital. And particularly as it's often optic neuritis, some of those patients are seen in the outpatient setting, so we can get in with treatment quickly. In patients where it's more severe, it doesn't recover quickly with steroids, then we would consider escalating to plasma exchange as our second-line treatment, and there's some retrospective data that suggests that plasma exchange can be useful. That's gonna be particularly for those people who don't have that quick response to steroids, or maybe more severe phenotypes like that brain involvement with ADEM or cerebral cortical encephalitis, where those patients might be in the hospital and quite unwell. I will say, we might get on to this, that sometimes MOG can be very, very severe and even fulminant, where there can be increased intracranial pressure, and these patients can be in the ICU, and it can be life-threatening. And so, it's really important to treat those patients aggressively, and some patients have even required hemicraniectomy or additional treatment. Sometimes IL-6 blocking medications have been used in that situation. So, monitoring and treating increased intracranial pressure in those rare patients, probably 2 or 3% that have the very severe attack, is important.   Dr Smith: I think one of the things I found interesting, and then I'd love to get your feedback on this, is that most patients with MOG seem to have a very readily treatable disorder that's monophasic, right? You treat them with steroids, and they do well. On the other extreme, there are these patients that have a much more malignant presentation, and there are some that sound like they benefit from prophylactic or some chronic therapy. What's your approach, right? In MS, we do serial scans to monitor, and obviously, our patients are on, you know, chronic disease-modifying therapy. How do you decide when you're going to provide some sort of prophylactic therapy? How do you monitor it? How long do you continue it?   Dr Flanagan: That's a great point. We don't know for sure yet, but I think for the most part, our approach has been if the patient has a single episode, they recover well from that episode. So, if that's optic neuritis, they're back to twenty/twenty vision. They have recovered well. We don't tend to use chronic maintenance immunotherapy. Sometimes after the first attack, we'll do a little bit of a slow taper, maybe over four, six weeks. We have done longer than that. And then we won't place them on any long-term treatment, because it's about 50% of patients that may have a monophasic disease, so we don't want to treat all those people who are destined never to have another relapse. On the other hand, if a patient had a very severe episode, they're in the ICU, they're intubated, some of those patients then afterwards we will start them at least temporarily on an attack prevention medication for at least a few years to get them through. Some patients will be very fearful of future relapses in that situation. Or if they don't recover well, if they're blind in one eye after an episode and then their other eye is vulnerable, or they're left with some residual deficits neurologically from a myelitis, then we would often sometimes put those patients after the first attack. But most of the time, we're gonna wait and see if they get that second attack, and then once they have the second attack, that is when we would consider a steroid-sparing medication. But I will say that there's no proven medications. We don't have any clinical trial data available yet. So some of those patients with relapsing disease, we'll either try to enroll them in a clinical trial, or we'll use an off-label treatment to try and manage their disease based on what we've learned from neuromyelitis optica or from multiple sclerosis. A few different options seem to be better, and we can maybe get into that too.   Dr Smith: Yeah, let's go there. So, what options are there? You mentioned in more fulminant disease IL-6 inhibitors, and by that I assume you mean tocilizumab, but what are the options when you want to use prophylactic therapy?   Dr Flanagan: So, that tocilizumab can be beneficial in the very acute situation, in that malignant situation. But also as an attack prevention treatment, the IL-6 blockers seem to- some of the retrospective data seems to look like it works reasonably well, so we work and see if we can get that approved. Another medication that can work well is IVIG or subcutaneous immunoglobulin as a maintenance treatment, so we would sometimes give that, like, at least one gram per kilogram once a month. The benefit of that is it doesn't lower your immune system, so there's some advantages there, particularly in people who may be more prone to infections, older people. So, we'll sometimes use that. But we do get into a lot of challenges with insurance coverage, and it can be difficult to get these approved by insurance because we only have retrospective data out there. So then for some patients, if they're in a region where there's a clinical trial available, we might try to enroll them in a clinical trial. And there are some clinical trials underway now, so hopefully in the future we'll be able to have some FDA-approved medications that can have some Class 1 data that we can follow. Because it's hard when you're just following retrospective data or anecdotal reports, it's a little bit difficult to know exactly how well you're doing with your treatments.   Dr Smith: Well, Eoin, I wonder if we could finish up by just looking into the future, right? I mean, it sounds like a fun patient population to take care of because you've got lots of great therapies and can have a durable impact. But sure would be nice to have more evidence-based therapies and an FDA approval. What trials are going on? What's the future look like?   Dr Flanagan: Yep. So, there's some trials going on in the- a couple of worldwide trials. One is on an FCRN blocker called rozanolixizumab, which is kind of like a plasma exchange-type treatment which removes your antibodies, and it's a weekly subcutaneous treatment where adults are enrolled. And the second one is called satralizumab, which is another IL-6 blocking medication. And again, that one's given once monthly under the skin. And the trial for that also includes children down to age eighteen, so for adolescents, too, that can be an option. There are trials, I believe, in Asia for tocilizumab too, and there's one starting in Australia for rituximab. So, the good news is that we're going to have some really good data down the line for lots of different agents, and we'll be able to figure out which treatments work. And this will be really of great benefit to our patients when we get that Class 1 data to kind of guide us on what we should be using and really build on the success of some of the other conditions like neuromyelitis optica spectrum disorder, where we now have four or five approved, medications that work very well.   Dr Smith: Well, Eoin, thank you. This is a great conversation. I will say that it... the topic that I was a little intimidated about. I'm a simple peripheral nerve guy, as you know. But I think moreso than any other Continuum article I've read recently, I'm, like, loaded for bear. I can't wait to go back on the inpatient service and look for some MOG patients, because your article really left me feeling kind of prepared to think through this in a clinical setting. So, thank you for the conversation, and congratulations on a really wonderful piece for Continuum.   Dr Flanagan: Yeah, thanks so much. Always a great honor to be involved in the Continuum, and thanks to all the readers out there.   Dr Monteith: This is Dr. Teshamae Monteith, Associate Editor of Continuum Audio.

"Cancer and environmental disasters in particular, but the worsening of our environment, are really things that are great equalizers. And we recognize that we're all kind of in this world together. We can really face these issues on a more human level. I think always recognizing that if we look at something, we think, 'Well, that doesn't relate to me or that problem is it really isn't my problem'—it sure is," ONS member Margaret "Peggy" Rosenzweig, PhD, CRNP-C, AOCNP®, FAAN, ONS scholar-in-residence and distinguished service professor of nursing and Nancy Glunt Hoffman Chair in Oncology Nursing at the University of Pittsburgh School of Nursing in Pennsylvania told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice at ONS, during a conversation about the effects of the environment on cancer care and outcomes.

Highlights From This Episode "The process of establishing these research priorities usually happens every three or so years. And there's a lot of preliminary work of talking to multiple parties of interest regarding what they believe the research priorities are, what nurses are seeing in clinics and in the community, and really multiple opinions regarding where the direction of research for ONS should go. And we heard this time—loud and clear—from researchers, from nurses in clinics and in communities, from scholars, and multiple other interested parties, that the environment in a very broad context was very much a concern and specifically a concern for impact on cancer care delivery, quality, and outcomes." TS 1:49 "You can take some cancer outcome data and you can take patient data related to home address or zip code or even larger geographic areas and kind of do correlational studies to see 'Does one impact the other?' … There's been a lot of those in the literature. But they are very helpful because they're starting to define this idea that beyond the idea of just demographics—gender, age, race—that the whole concept of neighborhood and the influences of the neighborhood do impact cancer outcomes. And that's where we're seeing the sort of explosion in literature across multiple malignancies, stages of cancer, and across multiple questions—specific kinds of outcomes, everything from quality of life to tumor progression." TS 8:43 "There is growing literature around how cancer delivery can be better prepared for climate-related disasters. … There's a good article by Pamela Ginex that was published in Supportive Care in Cancer talking about climate disasters and oncology care. And that was really a systematic review looking at published literature and starting to classify where are the disruptions and how could we think about that from a research perspective. They ended up saying there are these patient-level outcome disruptions that of course include treatment disruption but also include this inability to communicate with the oncology care team, which is quite distressing. And there's a workforce disruption because there are very distressed clinicians who are experiencing the same climate-related disaster in their own lives and feeling like they are torn between their commitment to work and their commitment to family." TS 13:25 "After all these years in oncology nursing, I am convinced that we have to get the consideration of neighborhood. I think we do have to get back to the neighborhood level in order to boost the resilience of communities against cancer throughout the cancer trajectory." TS 31:53 "Let's take some of this to the community and boost the community in that way. I really feel like we have to think about just boots on the ground outside of the cancer center, instead of just documenting disparities or even doing interventional work, but still within our little ivory towers." TS 34:21 "You see the work of many in looking at the specific environmental risks to nurses through the toxic chemicals to which were exposed. But then thinking about the people who aren't as protected as nurses and the environmental workers, who are usually contracted out or not in unions, who don't have some of the same protections that nurses or other healthcare workers might have, and they are exposed to the chemicals without proper training or sometimes without protection. All of these things are very much worthy of an oncology nursing voice elevating these questions and saying, 'How can we study this? How can we best mitigate some of these risks?' Oncology nursing—we have to use our respect and good name in elevating all of these questions." TS 35:39

Advanced practice providers are a growing part of the healthcare workforce, but many organizations aren't necessarily seeing the productivity gains they expected. On today's episode, we examine new Kaufman Hall insights on why traditional physician-APP models often underperform, and how redesigning team roles, incentives, and compensation could yield better outcomes for clinicians and patients alike. Bonnie Proulx, DNP, APRN, PNP-BC, FAAN, Senior Vice President with Kaufman Hall and a member of the firm's Physician Enterprise practice, joins the podcast to explain more.
