Podcasts about intracranial

Spontaneous intracranial hypotension reflects a disruption of the normal continuous production, circulation, and reabsorption of CSF. Diagnosis requires the recognition of common and uncommon presentations, careful selection and scrutiny of brain and spine imaging, and, frequently, referral to specialist centers.  In this episode, Gordon Smith, MD, FAAN speaks with Jill C. Rau, MD, PhD, author of the article “Clinical Features and Diagnosis of Spontaneous Intracranial Hypotension” in the Continuum® June 2025 Disorders of CSF Dynamics 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. Rau is an assistant professor of clinical neurology at the University of Arizona, School of Medicine-Phoenix in Phoenix, Arizona.

Dr Smith: This is Dr Gordon Smith. Today I'm interviewing Dr Jill Rau about her article on clinical features and diagnosis of spontaneous intracranial hypotension, which she wrote with Dr Jeremy Cutsworth-Gregory from the Mayo Clinic. This article appears in the 2025 Continuum issue on disorders of CSF dynamics. I'm really excited to welcome you to the Continuum podcast. Maybe you can start by just telling our listeners a little bit about yourself? Dr Rau: Hi, thanks for having me. I'm really honored to be here, and I really enjoyed writing the paper with Dr Cutsforth-Gregory. I hope you guys enjoy it. I am the director of headache medicine at the Baba Bay Neuroscience Institute at Honor Health in Scottsdale, Arizona. I'm also currently the chair of the special interest group in CSF Dynamics at the American Headache Society, and I've had a special interest in this field since I first watched Dr Linda Gray speak at a conference where she talked about spinal CSF leaks and their different presentations. And they were so different than what I had been taught in residency. They're not just the post-LP headache. They have such a wide variety of presentations and how devastating they can be, and how much impact there is on someone's life when you find it and fix it. And I've been super interested in the field and involved in research since that time. And, yeah. Love it. Dr Smith: Well, thanks for sharing your story. And as I reflected on our conversation ahead of time and have been thinking about this issue… this is a cool topic, and every time I read one of these manuscripts and have the opportunity to speak with one of the authors, I learn a ton, because this was something that wasn't even on the radar when I trained back in the 1800's. So, really looking forward to the conversation. I wonder if you could really briefly just summarize or remind for everyone the normal physiology about CSF dynamics, you know, production, absorption, and so forth? Dr Rau: So, the CSF is the fluid that surrounds the brain and the spinal cord, and it's contained by the dura, which is like a canvas or a sac that covers that whole brain and spinal cord. And within the ventricles of the brain, the choroid plexus produce CSF. It's constantly producing and then being reabsorbed by the arachnoid granulations and pushed into the venous space, the cerebral sinuses, venous sinuses. And also some absorption and push into the lymphatics that we've just learned about in the past year. This is kind of new data coming out, so always learning more and more about CSF, but we know that it bathes the brain and the spinal cord, helps keep some buoyancy of the brain as well as pushing nutrients in and pulling out metabolic waste. And it sort of keeps the brain in the state of homeostasis that's happy. And so, when there's a disruption of that flow and the amount of fluid there, that disrupts that, that can cause lots of different symptoms and problems for people. Dr Smith: One of the many new things I learned is that even the name of this---spontaneous intracranial hypotension---is misleading. And I think this is clinically relevant, as we'll probably get to in a moment, but can you talk a little bit about this? Is this really like a pressure disorder or a volume disorder? Dr Rau: Yeah. It's almost certainly a volume disorder. We do see in some people that they have low pressure, and it's still part of the diagnostic criteria. But it's there because if you have a low pressure, if you measure an opening pressure and it's below six, if you're measuring it in the spine in the right place, then you have indication that there's low volume. But there's over 50% of people's opening pressure who have a spinal CSF leak, have all the symptoms and can be fixed. So, they have normal pressure in 50% of the people. So, it is an inaccurate term, hypotension, but it was originally discovered because of the thought that it was a low-pressure situation. Some of the findings would suggest low pressure, but ultimately, we are pretty sure it's a low-volume condition. Dr Smith: Another new thing that I learned that really blew me away is how bad this can be. I did a podcast with Mark Burish about cluster, and I was reminded many cluster patients are pushed to the point of suicidal ideation or committing suicide by the severity of pain. And this sounds like for many patients it's equally severe. Can you maybe paint a picture for our listeners why this is so clinically important? Dr Rau: A large number of people, even people who are known to have leaks because they've had them before or they've releaked, they have a lot of brain fog and cognitive impairment. They often have severe headaches when they're upright. So, orthostatic headache is probably the number one most common symptom, and those headaches are one of the worst headaches out there. When people stand up, their fluid is not supporting the brain and there's an intense amount of pain. And so, they spend a large portion of their lives horizontal. And there's associated symptoms with that, it's not just headache pain and brain fog. There's neck pain. There's often subsequent disorders that accompany this, like partial orthostatic tachycardia syndrome. We don't know if that's because of deconditioning or an actual sequela of the disease, but it's a frequent comorbidity. We have patients that have extreme dizziness with their symptoms, but many patients are limited to hours, if that, upright per day, combined, total. And so they live their lives, often, just in the dark, lots of photophobia, sensitive to the light, really unable to function. It's also very hard to find and so underrecognized that a lot of patients, especially if they don't have that really clinical symptom of orthostatic headache. So, it's often missed. So, they're just debilitated. You know, treatments don't work because it's not a migraine and it's not a typical headache. It's a mechanical issue as well as a metabolic issue and not found, not a lot helps it. Dr Smith: So, you know, I have always thought about this as really primarily an orthostatic symptom. I wonder if you can talk about the complexity of this; in particular, kind of how this evolves over time, because it's not quite that simple. And maybe in doing so, you can give our listeners some pearls on when they should be thinking about this disorder? Dr Rau: A large portion of people do have headache with spinal CSF leak, in particular, spontaneous intracranial hypertension- hypotension, excuse me. And that's something to be thought about, is that there are spontaneous conditions where people have either rupture of the dural sac, or an erosion of the dural sac, or a development of a connection between the dura and the venous system. And that is taking away or allowing CSF to escape. In these instances that patients have spontaneous, there may be a different presentation than if they have, like, a postdural puncture or a chronic traumatic or iatrogenic leak. And we're not sure of that yet, but we're looking into that. Still, the largest presentation is headache, and orthostatic headache is very dominant in the headache realm. But over time, patients' brains can compensate for that lack of CSF and start overproducing---or at least we think that's probably what's happening. And you may see a reduction in the orthostatic symptoms over time, and you may see an improvement in the radiographic findings. So, there are some interesting papers that have been published that look at these changes over time, and we do see that sometimes within that first three to four months; this is the most common time to see that change. Other patients may worsen. You may actually see someone going from looking sort of normal radiographically to developing more of a SIH-type of picture on the brain. And so it's not predictable which patients have gone from orthostatic to improvement or the other way around, both radiographically and clinically. So, it can be quite difficult to tell. So, for me, if I have a patient that comes to me and they're struggling with headache… if it's orthostatic, very clearly orthostatic: I lay down, I get considerably better or my headache completely goes away. And then when I stand up, it comes on relatively quickly, within an hour. And sometimes it's a worsening-throughout-the-day type of thing, it's lowest in the morning and it worsens throughout the day. These are the times that it's most obvious to think about CSF leak. Especially if that headache onset relatively suddenly, if it onset after a small trauma. Like I've had patients that say, you know, I was doing yoga and I did some twists and I felt kind of a pop. And then I've had this headache that is horrible when I'm upright but is better when I lay down ever since, you know, since that time. That's kind of a very classic presentation of spinal CSF leak or spontaneous intracranial hypotension. Maybe a less common presentation would be someone who comes to you, they've had a persistent headache for a couple years, they kind of remember it started in March of a couple years ago, but they don't know. Maybe it's, you know, it's a little better when they lay down. It may be a little worse when they're up moving around, but so is migraine, and it's a migrainous headache. But they've tried every migraine drug you can think of. Nothing is responding, nothing helps. I'm always looking at patients who are new daily, persistent headaches and patients who aren't responding to meds even if it's not new daily, but they have just barely any response. I will always go back and examine their brain imaging and get full spine to make sure I'm not missing. And you can never be 100% sure, but it's always good to consider those patients to the best of your ability, if that- have that in the back of your mind. Dr Smith: So obviously, goes without saying, this is something people need to have on their radar and think about. And then we'll talk more about diagnostic tools here in a second. But how common is this? If you're a headache doc, you see a lot of patients who have intractable headaches. And how often do you see this in your headache practice? Now you're- this is your thing, so probably a little more than others, but, you know, how common will someone who sees a lot of headache encounter these patients? Dr Rau: If you see a lot of headache, I mean, currently the thought is it's about 5 in 100,000. That was from a study before we were finding CSF venous fistulas. I think a lot of us think it's more common than that, but it's not super common. We don't have good estimates, but I would guess between 5 and 10 for 100,000 persons, not “persons who come to a tertiary headache clinic with intractable headaches”. So, it's hard to gauge how frequent it is, but I would say it's considerably more frequent than we currently think it is. There's still a group of people with orthostatic headaches that we can't find leaks on; that, once you treat other things that can cause or look for other things that can cause orthostatic headaches. So, there may be even still a pathophysiology out there that is still a leak type. Before 2014, we didn't even know about CSF venous fistulas. And now here we are; like, 50% of them are CSF venous fistulas. So, you know, we're still in a huge learning curve right now. Dr Smith: So, I definitely want to talk about the fistulas in a second. But before moving on, one of the things that I found really interesting is the wide spectrum of clinical phenotype. And we obviously don't have a lot of time to get into all of these different ones, but the one that I was hoping you might talk about---and there's a really great case, and you're on bunch of great case, a great case of this---is brain sagging dementia, not a term I've used before. Can you really briefly just tell our listeners about that, because that's a really interesting story and a great case in your article? Dr Rau: Yeah. So, brain sag dementia is a… almost like an extreme version of a spontaneous intracranial hypotension. Where there is clear brain sag in the imaging---so that's helpful---but the patients present kind of like a frontotemporal dementia. And when this was first started to being determined, you could turn the patient into Trendelenburg, and sometimes they would improve. There are some practitioners that have introduced fluid into the thecal sac and had temporary improvement. Patching has improvement, then they leak again, sometimes  not. But the clinical changes with this have been pretty tremendous to be able to identify that that's a real thing. And in some cases, out of Cedars Sinai, you know, who does a lot of the best research in this, they've had lots of cases where they can't find the leak, but there's clear brain sag that fits with our clinical picture of CSF leaks. So, we're on a learning curve. But yeah, this- they really present. They have disinhibition and cognitive impairment that is very similar to frontotemporal dementia. Dr Smith: Well, so let's talk about what causes this. You mentioned CSF venous fistulas. I mean, that was reported now just over a decade ago, it's pretty amazing. That accounts for about half of cases, if I understand correctly. What are the other causes? And then we'll talk more about therapy in a minute, but what causes this? Dr Rau: So, within the realm of spontaneous, you know, we say it's spontaneous. But the spontaneous cases we account for, they can be tears in the dura, which are usually sort of lateral tears in the dura. They can be little places that rubbed a hole, often on an osteophyte from the spine. They can come from these spinal diverticuli. So, I always describe it to my patients like those balls that have mesh and squishy, and you squeeze them in the- through the mesh, there's the extra little bubbling out. If you think of like the dura bubbling, out in some cases, through the framing of the spine, right where the spinal nerve roots come out, they should poke out like wires from the dura. But in many cases they poke out with this extra dura surrounding them, and we call that spinal diverticuli. And if you imagine like the weakening of where you squeeze that, you know, balloon through your fingers, in those locations, that's a very common place to find a CSF leak, and you can imagine that the integrity of the dura there may be less than it would be if it were not being expanded in that direction. And that's often the most common place we see these CSF venous fistulas. So, you can get minor traumas; like I said, it can be spontaneous, like someone just develops a leak one day. It can be rubbed off, and it can be a development of a connection between the dura and the venous system. There are also iatrogenic causes, but we don't consider them spontaneous. But when you're considering your patients for spontaneous cases, you should consider if they've ever had chronic---even long, long time ago---had any spinal implementation, procedures near the spine, spinal injections, LPs in the past, and especially women who've had epidurals in pregnancy. Dr Smith: All right, so we see a patient, positional severe headache, who meets the clinical criteria. Next step, MRI scan? Dr Rau: Yeah. So, the first thing is always to get the brain MRI with and without contrast. Most places will have a SIH or a spinal CSF leak protocol, but you should get contrast because one of the most pathognomonic findings on brain MRI is that smooth diffuse dural enhancement. And that's a really fantastic thing when you find it, because it's kind of a slam dunk. If you find it, then you will see other findings. It almost never exists alone. But if you see that, it's pretty much a spinal CSF leak. But you're also looking for subdural collections, any indication of brain sag. We do have these new algorithms that have come out in the past couple of years that are helpful. They're not exclusionary---you can have negative findings on the brain and still have spinal CSF leak---but the brain MRI is extremely helpful. If it's positive for the findings, it really does help you nudge you in the direction of further investigations and treatments. Dr Smith: And what about those further investigations and treatments, right? So, you see that there's findings consistent with low pressure, and I guess I should say low intracranial CSF volume. Be that as it may, what's the next step after that? Dr Rau: Depends on where you are and what you can do. I almost always will get a full spine MRI: so, C spine, T spine, and L spine separately. Not, you know, we don't want it all in one picture, because we want to get the full view. And you want to get that with at least T2 highly- heavily T2 weighted with fat saturation in at least the sagittal and axial planes. It's really helpful if you can get it in the coronal planes, but we have to have- often have good talks with your radiologist to get the coronal plane. I spoke about the spinal diverticuli earlier, and I want to clarify a little bit of something. The coronal image will show those really nicely. It's interesting, but 44% of people have those. So just having the spinal diverticuli does not indicate that you have a leak. But if you have a lot of those, there may be more likelihood of having leak than if you don't have any of those. So, I will get all of those and I will look at them myself, but I've been looking at them myself for a long time. But a lot of radiologists in community hospitals, especially not- nonneuroradiologists, but even neuroradiologists, this isn't something that's that everybody's been educated about, and we've been learning so much about it so rapidly in the past ten years. It's not easy to do and it's often missed. And if it's not protocoled properly, the fat saturation's not there, it's very hard to see… you can have a leak and not see it. Even the best people, like- it's not always something that's visible. And these CSF venous fistulas that we talked about are never visible on normal MRI imaging. Nonetheless, I will run those because if I can find a leak---and 90% of the ones that are found on MRI imaging are in the thoracic spine. So that's where I spend the most of my time looking. But if you find it, that's another thing to take to your team to say, hey, look, here it is, let's try and do this, or, let's try and do that, or, I've got more evidence. And there are other findings on the spine; not just the leak, but other findings, sometimes, you can see on spine that maybe help you push you towards, yes, this is probably a leak versus not. Dr Smith: So, your article has a lot of great examples and detail about kind of advanced imaging to, like, find the fistula and what not. I guess I'm thinking most of our listeners are probably practicing in a location where they don't have a team that really focuses on that. So, let's say we do the imaging of the spine and you don't find a clear cause. Is the next step to just do a blood patch? Do you send them to someone like you? What's the practical next step? Dr Rau: Yeah, if your- regardless of whether you find a leak or not, if your clinical acumen is such that you think this patient has a leak or I've treated them for everything else and it's not working and I have at least a high enough suspicion that I think the risk of getting a patch is lower than the benefit that if they got a patch and it worked, I do send my patients for non-directed blood patches, because it currently does take a long time to get them to a center that can do CT myelograms or any kind of advanced imaging to look for sort of a CSF venous fistula or to get treated outside of a nondirected patch. You know, sometimes nondirected patches are beneficial for patients, and there's some good papers out there that sort of explain the low risks of doing these if done properly versus the extreme benefit for patients when it works. And, I mean, I can't tell you how many people come in and tell me how their lives are changed because they finally got a blood patch. And sometimes it works. And it's life-changing for those people. You know, they go back to work. They can interact with their kids again. Before, they didn't know what was wrong, just had this headache that started. So it's worth doing if you have a strong clinical suspicion. Dr Smith: Yeah. I mean, that was great. And, you know, to go back to where we began, this is severe. It's something like 60% of patients with this problem have thought about suicide, right? And you take this patient and cure the problem. I feel really empowered having read the article and talked to you today. And so, I'm ready to go out and look for this. Thank you so much for a really engaging conversation. This has been terrific. Dr Rau: Thank you. I appreciate it. I enjoyed being here. Dr Smith: Again, today I've been interviewing Dr Jill Rau about her article on clinical features and diagnosis of spontaneous intracranial hypotension---which I guess I should say hypovolemia after having talked to you---which she wrote with Dr Jeremy Cutsworth-Gregory.

In the December 2024 episode of Critical Decisions in Emergency Medicine, Drs. Danya Khoujah and Wendy Chang discuss managing alcohol withdrawal in the emergency department and evaluation and management of spontaneous intracranial hemorrhage. As always, you'll also hear about the hot topics covered in CDEM's regular features, including a boy with pharyngitis and a rash in Clinical Pediatrics, a reverse total shoulder arthroplasty dislocation in Orthopedics and Trauma, a zipper injury in The Critical Procedure, diagnosis and treatment of sexually transmitted infections in The LLSA Literature Review, and a newborn with bloody stool in The Critical Image.

The incidence of brain metastases is higher in patients with non-small cell lung cancer (NSCLC) than in patients with most other cancers, and the development of brain metastases is associated with poor prognosis. The objective of the podcast is to provide information about current and future treatments for brain metastases that develop in patients with EGFR-mutated NSCLC. The panel discusses surveillance and management of patients with brain metastases, different types of currently used treatments, and recent data on the intracranial efficacy of antibody–drug conjugates (ADCs). The panel also discusses current and future studies of ADCs in patients with EGFR-mutated NSCLC with brain metastases.

Headache medicine relies heavily on the patient's history, perhaps more than any other field in neurology. A systematic approach to history taking is critical in evaluating patients with headache. In this episode, Katie Grouse, MD, FAAN, speaks with Deborah Friedman, MD, MPH, FAAN author of the article “Approach to the Patient With Headache,” in the Continuum April 2024 Headache issue. Dr. Grouse is Dr. Grouse is a Continuum® Audio interviewer and a clinical assistant professor at the University of California San Francisco in San Francisco, California. Dr. Friedman is a neuro-Ophthalmologist and headache specialist in Dallas, Texas.

Today, I'm interviewing Dr Deborah Friedman on approach to the clinic patient with headache, which is part of an issue on headache. Dr. Friedman is a neuro-ophthalmologist and headache specialist in Dallas, Texas. Deborah, I'd love if we could just start by you telling us more about you. How did you become interested in the diagnosis and treatment of headache? Dr Friedman: I guess one of the lessons in life that I have learned regarding this question is, “never say never.” I started as a neuro-ophthalmologist - that's what I did my fellowship in. My very first job was in Syracuse, New York, at Upstate Medical University, and there was no headache specialist in Syracuse at the time. And I started seeing neuro-ophthalmology patients and specifically told the person who did my scheduling for me, “Do not schedule headache patients. I am not a headache doctor; I'm a neuro-ophthalmologist.” Well, these people just snuck in the door. They got referred in for their visual disturbances, right - we know what that was - or for their, you know, transient loss of vision or some type of visual manifestation of migraine or eye pain, right? So, I started seeing the patients and I figure, “Well, I did a neurology residency; I can treat headache as well as anybody else.” And so I started treating their headaches. and they would come back to see me in follow-up and say, “You gave me my life back,” and I was pretty blown away by that. This was a few decades ago, and we didn't give very many people “their lives back” at the time in neurology, so I decided I should go learn more about headache medicine. And I started attending national meetings of what is now the American Headache Society. I found that I really, really loved treating headache, and it has a natural marriage with neuro-ophthalmology. As my career progressed, I ended up doing more headache medicine and less neuro-ophthalmology, but I still love both. Dr Grouse: Yeah, absolutely. I think the treatment of headache can be so satisfying and I'm so happy to hear that you were able to discover that love of treating headache in your own career. Why do you think it's important for neurology clinicians to read your article? Dr Friedman: Well, headache is the most common disorder seen in general neurology. It is actually the most common neurological disorder overall, by a factor of ten. And it is one of the most common causes of neurologic disability worldwide - like it's in (routinely in) the top five. So, it's an important problem, and patients are going to come see us, and we need to know how to effectively interview them so we can effectively manage them. I think, in a nutshell, that's why. Dr Grouse: You mentioned in your article the importance of making time to discuss the headache - so much so that, actually, you said that if they mentioned it offhand at the end of the visit that they have a headache, you really should be scheduling time for them to come back, to prepare and organize the information, and to have the time to really talk with them. I find this is such an important point and, in my mind, really gets to the heart of what you're trying to tell us in your article - that the way you take the history can make or break your ability to diagnose and treat the problem. Can you talk more about that? Dr Friedman: Sure. The history is absolutely the most important part of the office visit with headache medicine. I mean, they always say, “In medicine and in neurology, ninety percent of the diagnosis is made by history.” And that is more than true in headache medicine. So, you have to really get a good history. And it's a skill, but there's also kind of an art to it. So, there are certain questions you want to have answers to, but there's also this art of how to relate to the patient and how to really get them to tell you what you need to know, right? When I wrote the article, I really tried to convey that, because I think a lot of it can be learned. But there are a lot of nuances to taking a headache history, and I think that, for many people, it's helpful to have a guide to do that. Dr Grouse: Following up on what you just said - you mentioned, of course, the art of taking the good history for headache, which I completely agree is absolutely true. However, in your article, you also mentioned that things like various questionnaire tools, AI, can also be really helpful for diagnosis, which seems to be the opposite of the art of medicine. Tell me more about how you can incorporate that into taking your history. Dr Friedman: I find that questionnaires are incredibly helpful. I devised my own - it is one of the questionnaires that's available in the article (there's a link for it). It's not that I just read the questionnaire and I walk in the room knowing exactly what's going on - sometimes that's true - but at least I have a good idea of what I'm going to be facing when I walk into the room and start talking to the patient. The other reason (perhaps more importantly) that I think it's so helpful is because it gets the patient thinking about the details of their headaches and the details of their life and, you know, like, what medications they've taken in the past. And it really prepares the patient for the interview. In a lot of ways, I think that's more important than the information it gives me. But I do look at all the questionnaires, and I'll say, “Well, you know, you checked off this, and what did you mean by that? And you said this or that on your questionnaire.” And I kind of refer to it so they at least know that I looked at it - there's nothing more irritating than filling out a long questionnaire and then nobody ever looks at it - so, I do look at it and I do acknowledge in front of them that I have looked at it and am looking at it. But I think that they help in many ways. There are programs in AI that the patient will just enter information into online and the program will just spit out a narrative, as well as a diagnosis or a differential diagnosis. For clinicians that are really under a lot of time constraints, I think these can help considerably as well. Dr Grouse: That's really interesting, and that actually brings me to the next question I wanted to ask, which was - do you have any tips for the many busy neurologists out there (many listening to this podcast right now) who really want to do a good job gathering information and taking a careful history but are really limited on time to be able to do this? What other tools out there would you recommend for them, or tips? Dr Friedman: Yeah, I think that probably the questionnaires and the AI-based programs are very helpful. There is - I have no financial relationship with this company; I just happen to know about it and I know the people that developed it - but it's called BonTriage (as opposed to bon voyage), and it was developed by headache specialists. And I've seen the product and I've seen the output that can be used, and I think that one is incredibly helpful. It was really made for primary care, so that people could do this thing online and then just walk in with a piece of paper, hand it to their primary care doctor, and they'd have the whole history and the differential diagnosis. But it's equally as useful for neurologists. Dr Grouse: How about in history taking - any tricks to get the history you need and let the patient feel heard without necessarily taking lots of time going down the wrong pathway? Dr Friedman: Yeah, that can be really hard, and sometimes patients just want to bring you down what you would consider the wrong pathway (obviously, they consider it the right pathway). People have different styles of interviewing and people have different styles of answering the question. I find that it's often very obvious early on whether the patient is going to do better by asking closed-ended questions or asking open-ended questions. I always start with open-ended questions because the research says that that's more helpful, and that getting the patient to describe their headache disability is one of the most important things that you can do, so you should ask it right up front. But some people - when you ask them the questions (as you probably know), they just go on and on and on, and it's really not the way that you might process information. So sometimes I just have to take it back and ask them very specific questions – “Do you have this symptom? Do you have that symptom? How long does this last? What triggers your headache?” - that kind of stuff. It's very, I think, specific to an individual patient. Dr Grouse: Yeah, that absolutely makes sense. Your article highlights some important and frequently missed causes of headache, including hemicrania continua and intracranial hypotension, and specifically, you have some example cases that you talk about. I have to say, reading those certainly triggers my own latent fear of misdiagnosis of these important causes of secondary headache. Can you highlight some of the important questions to ask or situations to keep in mind in order not to miss these? Dr Friedman: Sure. You know, those examples in the article came from my practice. I had to alter them a little bit because they're not supposed to sound like real people, but the patient with hemicrania continua was a real - I wouldn't say necessarily “eye opener” - but it really hit home with me. I spent all this time taking the history from the patient. She'd seen numerous doctors beforehand; they all thought she had chronic migraine. I take her history and I think she's got chronic migraine too, but she's trialed several medications; they haven't really worked, so, you know, we kind of ended it. I said, “Well, I think you have chronic migraine.” She came back for her follow-up visit and looked at me and said, “Could I have hemicrania continua?” At which point, I panicked. It's like, “Oh my god - I think I take a pretty good history, but what did I miss?” I'm like, looking through the note from the last visit and trying to figure out where I went wrong. And where I went wrong was, I never asked her, “Are you ever completely headache free?” And that is such an important question to ask because most often, when people come in and they start talking about their headaches, they talk about their worst headaches, right? Those are the ones that are really interfering with their lives. They often will just totally neglect to tell you that they have a headache almost every single day, but it's just mild and they don't pay attention to it. That was like a big lesson for me, and I try - it's even on my questionnaire – “Are you ever headache free?,” because it's just so important to know that. Intracranial hypotension is also one that you really have to be a detective for. A lot of times, the imaging will help us, but about ten, fifteen, twenty percent of people with intracranial hypotension have normal imaging. Then it becomes like this whole quest of making a diagnosis based on your clinical impression, right? So, there are just a lot of different things that you can ask and there are a lot of different symptoms people can have. One of the important lessons I learned in there was asking about orthostatic headache; the common way to ask that is, “Does it get better when you lie down?” Well, with few exceptions, most people with headache prefer to lie down, right? People with migraine prefer to lie down. But their headache doesn't get better just because they were lying down. It gets better because they took medicine and maybe they went to sleep. So, it's not just, “Is it better when you're lying down?” Is not going to sleep is part of it? And conversely, we want to know like what they feel like when they first wake up in the morning before they get out of bed, right? So just asking about, “Well, what's your headache like in the morning?” - that's not going to necessarily get the answer you want. So there are, again, kind of fine points about asking some of these questions to really find out what you need to know. Dr Grouse: Absolutely - that makes sense, that the intracranial hypotension case was another one that really, you know, makes me go back and think, “Gosh, how many of these might I have missed in my own career?” You know, such an easy-to-miss case based on what was described. Dr Friedman: I go through the same thing. I think that, early in my career, I could think back to patients that I probably missed that diagnosis. One of them I even sent to (may he rest in peace) Dr Mokri, who described it, and I sent him the imaging. He said, “No, this patient doesn't have it.” But knowing what we know now, I think she probably did. Dr Grouse: Wow. Transition to some other types of questions - what's the most common misconception you've encountered in treating patients with migraine? Dr Friedman: I would say that a lot of people think that migraine has to be (as the name implies) hemicranial. A substantial proportion of adults and even a higher proportion of children have migraine headaches that affect both sides of the head. I think that's really the most common misconception. Dr Grouse: What's the easiest mistake to make (and potentially avoid) when treating patients with migraine, or headache in general? Dr Friedman: Studies have been done looking at this question in migraine. The first mistake is not giving the patient a correct diagnosis. And it is surprising in real life how many people walk out of the doctor's office and nobody's ever told them, “You have migraine with aura,” or “You have chronic migraine,” right, and giving them a very specific diagnosis. Second most common mistake in treatment is not offering them an acute treatment. So, many people are using over-the-counter medications that are not very effective, or even prescription medications that are not very effective. We have a lot of good treatments out now, and basically every patient with migraine should be offered an acute treatment. We also know that preventive treatment is massively underutilized. Again, studies (mostly by Richard Lipton and his group) have interviewed patients and done population studies, and people who clearly meet contemporary guidelines for offering preventive treatment are never offered it. So, I guess those would be my top three. Dr Grouse: Going on the theme of patients maybe not being offered the optimal treatments, what's the greatest inequity or disparity you see in treating patients with headache disorders? Dr Friedman: The first thing that contributes to that is - there is a shortage of headache specialists. There's also a shortage of neurologists, so that's a problem. There are certain groups that are less likely to seek care for headache. If people don't seek care, it makes it harder for us to treat them. African American males, in particular; Hispanics. I think that some of this might be stigma; some of this just might be cultural - I'm not sure. Women are more likely to seek care for migraine than men are. But there are what they refer to as, like, “islands of health-care disparity” throughout our country, where there are just not enough physicians, or even advanced practice providers working with physicians, to be able to take care of all these people. So, it's estimated that there are well over forty million people with migraine alone in the United States (not to mention all the other kinds of headaches), and there are really not enough of us to go around, and there are very long waiting times to get in to see us. So, some people will end up using the emergency room to treat their headaches, which is totally suboptimal and not a good experience for the patient, either. So, I think there are a lot of aspects to disparities in migraine care, and there is a group in the American Headache Society that actively focuses on this issue and has written papers about it. But I think it's multifaceted and it's going to take a lot of effort on both the part of us, as clinicians, as well as patients, recognizing that there is good treatment out there and people shouldn't have to live with these kinds of disorders. Dr. Grouse: Absolutely. This has been such an interesting article. I just wanted to end with one last question, which is, what do you think is the most important clinical message of your article that you hope our listeners take away from this podcast? Dr Friedman: I was really happy to be asked to write this article for Continuum. And I'm glad it is the lead article in Continuum because I think that taking the headache history is by far and away the most important part of the headache medicine evaluation. When I was asked to write it, I was specifically requested to write it from the perspective of a clinician seeing adult patients. And I just want to let the audience know that I did not neglect the pediatric patients - that there is a different chapter in Continuum that addresses the specifics of taking a history and what's important to ask from pediatric patients. It was really a joy to write the article. I hope that people read it and learn from it and enjoy it. Dr Grouse: I really thoroughly enjoyed this article - it was so interesting. Even as someone who does a lot of headache diagnosis and treatment myself, I learned a lot. I think it's such a rich source of information and I hope everyone takes advantage of the opportunity to read it and learn a little bit more about headache treatment and diagnosis. Thanks so much for coming to talk with us today. Dr Friedman: Thank you so much for inviting me. It was a pleasure.

A brain aneurysm is also called a cerebral aneurysm or an intracranial aneurysm and refers to the same diagnosis. Muscular-walled tubes blood vessels called arteries are part of our circulation system. These tubes are how blood is conveyed from the heart to the brain, carrying oxygen and nutrients to support the brain and its functions. A diagnosis of a brain aneurysm means that a bulging, weak area exists in the wall of one of the arteries that supplies blood to the brain.Sandra Narayanan, MD, FAHA, FANA, FSVIN, FAAN, is board-certified in neurology and vascular neurology by the American Board of Psychiatry and Neurology and CAST (Committee on Advanced Subspecialty Training)-certified in neuroendovascular surgery.

Contributor: Travis Barlock MD Education Pearls: The Cushing Reflex is a physiologic response to elevated intracranial pressure (ICP) Cushing's Triad: widened pulse pressure (systolic hypertension), bradycardia, and irregular respirations Increased ICP results from systolic hypertension, which causes a parasympathetic reflex to drop heart rate, leading to Cushing's Triad.  The Cushing Reflex is a sign of herniation Treatment includes: Hypertonic saline is comparable to mannitol and preferable in patients with hypovolemia or hyponatremia Give 250-500mL of 3%NaCl 20% Mannitol - given at a dose of 0.5-1 g/kg Each additional dose of 0.1 g/kg reduces ICP by 1 mm Hg 23.4% hypertonic saline is more often given in the neuro ICU 8.4% Sodium bicarbonate lowers ICP for 6 hours without causing metabolic acidosis Non-pharmacological interventions: Raise the head of the bed to 30-45 degrees Remove the c-collar to improve blood flow to the head Hyperventilation induces hypocapnia, which will vasoconsrict the cerebral arterioles You hyperventilate on the way to the OR. Otherwise, maintain normocapnia. References Alnemari AM, Krafcik BM, Mansour TR, Gaudin D.

Real World studies can provide the foundational support necessary for clinicians to effectively manage anticoagulated patients with severe, often life-threatening intracranial and gastrointestinal bleeding. While randomized controlled clinical trials have provided the initial data necessary for appropriate use of reversal agents such as andexanet alfa for Factor Xa associated bleeding, broader studies enrolling thousands of patients, many with significant co-morbidities, are extremely valuable to clinicians. New information regarding the randomized controlled trial ANEXXA-I, which was halted due to andexanet alfa efficacy, provides additional information supporting reversal therapy for severe bleeding.

This week on the BackTable ENT podcast, Dr. Gopi Shah and Dr. Amanda Stapleton, a pediatric otolaryngologist from UPMC Children's Hospital of Pittsburgh, chat about the unique challenges of treating pediatric sinus and skull base diseases, orbital complications, and biofilm-covered Moraxella. They discuss source control, biofilm, and her research focused on the bacteriology of pediatric chronic sinusitis and patients with cystic fibrosis. --- SHOW NOTES First, they discuss how to recognize the signs and symptoms of pediatric patients who present with orbital or intracranial abscesses and how age and location of the abscess can influence treatment decisions. They also explain how to distinguish between intracranial and orbital abscesses and how to recognize the symptoms of sphenoid sinusitis. Both doctors emphasize the importance of involving infectious disease colleagues to evaluate antibiotic coverage and surgical indications. Next, the doctors discuss the techniques for sinus surgery, including the use of a scope for visualization, warm irrigations, navigation, and augmented reality systems in the acute setting. Dr. Stapleton also provides tips on when to remove a middle turbinate and the importance of source control, especially in patients under the age of seven. An adenoidectomy may be necessary if the patient has had multiple colds throughout the winter and the decision is made to take down the lamina to drain an abscess pocket. Finally, the doctors discuss the follow up process for children with chronic sinusitis, which may include office endoscopy and allergy testing, and discuss the rare cases of intracranial abscesses. In addition to being vigilant and proactive in monitoring the potential for repeat infections, imaging to detect any scarring or residual mucosal inflammation that might have resulted from the initial infection is also helpful.

A 27-year-old, otherwise well, woman complains of recurrent headache that occurs every 1‒2 weeks and lasts up to 24 hours. During headache, she reports sudden onset of unilateral pulsating pain, nearly always on the left side that is accompanied by photophobia, phonophobia and mild nausea without vomiting. Her first headache occurred when she was approximately 12-years-old.  Her neurological exam is within normal limits. What is this clinical scenario most consistent with?A. Cluster headache B. Tension-type headache C. Intracranial lesion D.
