Today, I've got the great pleasure of interviewing Dr Elia Sechi about his article on aquaporin-4 antibody-positive NMOSD and MOGAD, which appears in the August 2024 Continuum issue on autoimmune neurology. Dr Sechi, before we dig into this really exciting topic about NMOSD and MOGAD, perhaps you can tell our listeners a little bit about yourself, where you practice, how you got interested in this topic.   Dr Sechi: Hi, Dr Smith, and thank you for having me. So, my story begins here in Italy, actually - I did my med school and residency in neurology at the University Hospital of Sassari here in Sardinia. And after residency, I was lucky enough to be accepted at the Mayo Clinic in Rochester, Minnesota for a research fellowship - and that's where I spent the next three-and-a-half years, approximately. My fellowship was focused on autoimmune neurology, specifically demyelinating diseases of the CNS associated with antibodies – so, of course, NMOSD and MOGAD mostly, but also myelitis, MS, and autoimmune encephalitis – so, there's where I built most of my expertise in the field. And then, it was at the beginning of the pandemic (of the COVID pandemic) that I came back here to Italy to practice. And now, I work mostly as a neurohospitalist, and I also have my subspecialty outpatient service for patients with autoimmune neurological diseases.   Dr Smith: I wonder if you might just give us a minute or two about what it was like training in Mayo? I went to medical school there, and, you know, at the time, I thought that was just normal healthcare and normal training, and, you know, it was only later that I realized how amazing that was. I mean, this is where aquaporin-4 was discovered - I mean, what was that like? It must have been really cool training there with that team.   Dr Sechi: Yeah. You know, it's the temple of autoimmune neurology. It's fantastic. It's a great environment, very stimulating. You know, I think the great strength is that they see many patients with rare diseases, so, you get really confident with MRI features and clinical features with the history of the diseases, and this is important to recognize the typical features and differentiate from MS to do a good differential. And, of course, you know, the team is fantastic - superstars in the field. It's very, very stimulating. So, it's something that I definitely recommend. It was a fantastic experience.   Dr Smith: Well, you know what's great is, I don't know if you follow sports, but, you know, like, in the United States and college football, people refer to Gator Nation – right, these are all people who are fans of the Florida Gators. Or, maybe it's AC Milan nation in Italy. I don't want to get there (Roma, whatever), but there are all these people who've trained at Mayo, and, uh, what's great is it's a small world, right? So, I'm super excited to meet you and talk about this, because - I'm going to add you to my Rolodex, because when I see these patients (I'm a neuromuscular guy, but I do a fair bit of inpatient time), I'm always calling a small number of people, so I'm really pleased to meet you so I can put you on speed dial and ask you questions about these patients. I wonder if, maybe, we can begin? You know, in our preparatory discussions, I shared that I just came off our hospital service, and we had several of these patients, you know, where we were thinking about NMO or MOGAD as a cause for their problem - and I wonder if you just have any pearls or pitfalls in when we should suspect this, right? Most of us recognize bilateral optic neuritis, longitudinally extensive myelitis - we need to be thinking about these. Any pearls or pitfalls for when we should or should not be looking for these disorders?   Dr Sechi: Yeah, I think this is a great question. I think the first thing to pay attention is the phenotype. So, the clinical MRI phenotype that are typically associated with NMOSD and MOGAD, they are quite characteristic - and it's important to be aware of those phenotypes and how they differ from MS, because in my experience, one of the common misinterpretation (misconception) in clinical practice is just to test for AQP-4 and MOG antibodies in any patient with new-onset demyelinating disease of the CNS, even if it's typical MS. And, this is quite wrong, because MS is way more common in clinical practice - it's sixty, eighty times more common than NMO and MOGAD - and so, if you test all those patients without filter (indiscriminately) for antibodies, you increase the risk of false positivity exponentially, even if you have a highly specific test. So, first of all, I think it's good to select the right patients to test. As you said, patients with LTM, extensive involvement of the optic nerves on MRI, ADEM - there's also patients with cortical encephalitis phenotype (which is a rare phenotype of MOGAD), but not definitely good to test the typical MS patients. This is the first thing.   Dr Smith: Yeah, I mean, that's an issue in all of neurology, isn't it, right? I mean, it's an issue in sort of just sending, you know, the Mayo panel, the autoimmune encephalitis panels - you need to select patients carefully, but I think this attention to prior probability is something that we need to really focus on in multiple areas. So, I wonder if you might expand a little bit on assays. I do a lot of work in myasthenia and I know which labs do a really good job with, you know, acetylcholine receptor antibody testing and those that maybe do not, and there are different methodologies for testing - do you have any wisdom in terms of how to select a lab, what to look for, and how to interpret the results you see based on the particular assay that's being used?    Dr Sechi: Yeah, that's a critical point. I agree. And especially if you work in myasthenia, you're very well aware of the differences between different assays, and nowadays, most of the high-quality assays are cell-based assays (either fixed or live) - it's the same in myasthenia, and people need to pay attention to some of the less-specific assays. Let's say ELISA, for instance - testing AQP-4 and MOG antibodies with ELISA is quite dangerous, because the risk of false positivity is quite high. So, it's good to know what assays to trust most and also good to know what's the right specimen to send for antibody test. For instance, with AQP-4, we know that serum testing is recommended only, and the CSF doesn't add much, but with MOG, we know that approximately 10% of patients have an isolated positivity in the CSF, which is interesting, because it means that when you have a patient with a strong diagnostic suspicion as a phenotype that is highly suggestive for MOGAD and the serum testing is negative, you may consider testing the CSF to increase your sensitivity. So, this is very important.   Dr Smith: So, I have a question for you that may seem a little naïve, but I bet other people are thinking it - can you tell us why it is that these disorders affect optic nerve and spinal cord preferentially? And I think, for NMO, the whole area postrema thing seems awfully specific to me. What's the deal? Why are these areas preferentially affected by these antibody-mediated disorders?   Dr Sechi: This is a tough question. For NMO, we know, probably, there is higher expression of some of the isoforms. Let's say there is a higher density of AQP-4 molecules that target the most affected regions - so, of course, AQP-4 is preferentially expressed in the subependymal regions around the ventricles and in the spinal cord and optic nerves, but you may have, also, solutions along the cortical spinal tracts in case of the brain involvement. The area postrema is kind of a different explanation, because there is a sort of permeability - increased permeability - of the blood-brain barrier there. So, there are several factors in MOGAD - this is not very clear, so, this is a great topic to study in the future, I think.   Dr Smith: This is a really interesting area, and one that's really benefited by significant therapeutic development. I wonder if you might look a little bit in the future and tell us, maybe, the agent, or perhaps the target, that you're most excited about therapeutically that's coming down the road these days?   Dr Sechi: There are trials ongoing for MOGAD, which is the real need in terms of treatment, because for NMO, we already have three, four drugs that have been approved and which efficacy have been demonstrated by randomized clinical trials, and those are B-cell depleting agents, IL-6 inhibitors, and complement inhibitors. For MOGAD, this is still a gray zone, because the optimal treatment strategies remains to be defined. There are ongoing trials that are quite promising on IL-6 inhibitors and the inhibitors of the neonatal Fc receptor (which is also used in myasthenia gravis as you know). And something that seems to be quite effective - a good option for long-term treatment in these patients and relapse prevention - is also the periodic administration of IVIG (intravenous immunoglobulin), which is a nice option, for instance, in the children where you want to avoid immunosuppressants of other types. So, I think IL-6 is going to show to be very effective in the end. We'll see. We'll see.   Dr Smith: So, I wonder if I might just give you a vignette and get your thoughts about, kind of, acute management, right? I just took care of a patient who had a longitudinally extensive myelitis and she was essentially paraplegic and actually came in progressing fairly rapidly, and we, of course, started her on IV methylprednisolone, sent off the proper diagnostic testing - the question I have is, how quickly do you advance therapy and go to IVIG or plasma exchange when you're encountering these, right? It takes, you know, I think the turnaround time is, you know, often about a week to get these tests back (at least several days) - I mean, should we be going very quickly to plasma exchange in someone who has a severe phenotype? Is it okay to do three to five days of IV methylprednisolone and wait for the results to come back? What's the right approach?   Dr Sechi: I think this is a great question, actually. You know, management of the acute attacks probably is the most important thing, you know, to allow a good recovery, and I think timing of PLEX administration should be very short - so, the threshold for PLEX should be low, especially when the attack is severe, and this has to be done regardless of antibody testing results, which is typically not available before one or two weeks (at least a year in Italy), I think, in many hospitals. So, I think the risk-benefit ratio of administering PLEX is in favor of treatment in these patients, because the side effects (the potential side effects) are very rare and can be prevented. Some diseases, they can mimic NMO or MOGAD - they're very rare, and they can really worsen with PLEX. As an example, we can say spinal cord infarction can worsen, maybe, because of hypotension due to PLEX. Or some very rare infections, like one case, a bad case of intramedullary spinal cord abscess that looked really similar to an AQP-4 IgG-related LTM - and it was bad, because the patient had no fever, no signs of infection, the CSF culture was negative initially, so we ended up doing a biopsy after failure of PLEX and steroids. So, it is recommended to start within the first three to five days, preferentially, in severe cases, and this is great for the outcome of the patient, so, I do recommend PLEX as a second treatment option. And I'm not sure about IVIG acutely. There is some data on MOG, but it's still controversial - it works a lot when PLEX fails, but it can be considered after PLEX, of course. And there are some very rare patients that do not improve, even after IV methylprednisolone, PLEX, or IVIG, and so, you need to consider some rescue therapies. In those patients, it's kind of complicated, because there are some options, like IL-6 inhibitors seem to be quite effective and quite fast-acting for MOGAD attacks, and also eculizumab and complement inhibitors can be an option in patients with AQP-4 - but maybe less in patients with MOG. So, these are the possibilities (very quickly).   Dr Smith: So, you mentioned FcRn inhibitors a moment ago, and I wonder, do you see a future where - and I think you were mentioning them as maybe more chronic therapy? Correct me if I'm wrong.   Dr Sechi: Yeah, yeah.   Dr Smith: Do you foresee a role for these agents in acute management? I mean, there are some that, you know, very quickly lower immunoglobulin levels, though just looking out in the future, you think that these sort of infusion therapies that we think about chronic therapy (you mentioned, you know, complement inhibitors) are going to be useful in acute management?   Dr Sechi: Yeah, it depends. It's a good option to try. I'm not sure about the time to action. It's very dependent on that, because IL-6 inhibitors and complement inhibitors are very fast-acting (I think they can be effective already within twelve hours, 24 hours, which is good), but it's reasonable that, also, Fc inhibitors can be an alternative in the future. As far as I know, there is not much in the literature, but it's good to try in the future in case, acutely.   Dr Smith: Well, exciting times indeed. Elia, thank you so much for a great discussion. I thoroughly enjoyed this. I look forward to visiting you soon, and I want to congratulate you on a really great article that's very interesting and very clinically useful.   Dr Sechi: Well, thank you, Dr Smith.

The spinal cord serves as the main communication highway between the brain and body. Did you know that 80% of people with multiple sclerosis have spinal cord lesions on MRI? These lesions can disrupt specific neural pathways, leading to common MS symptoms like numbness, weakness, impaired coordination, balance issues, bladder problems, constipation, and sexual dysfunction. For instance, damage to the corticospinal tract on one side of the spinal cord can weaken an arm or leg. A remarkable autopsy study revealed that nearly 90% of people with MS still had active inflammation in the spinal cord. This finding brings new hope for potential treatments, even for older and progressive MS patients. Advances in imaging technology, including more powerful MRI scanners (3 Tesla and higher), are enhancing our ability to see inside the spinal cord, which is as thin as a pinky finger. Improved spinal cord imaging is driving the development of new therapies in clinical trials and helping identify those at risk for worsening disability, ultimately guiding better treatment decisions.

This article is a part of the August 2024 Continuum issue on autoimmune neurology. Welcome to the podcast, Dr Pittock. Could you introduce yourself to our audience?    Dr Pittock: Well, thank you very much, Dr Berkowitz. So, yeah, I'm a neurologist at the Mayo Clinic. I direct the neuroimmunology laboratory with Dr McKeon and Dr Mills here, and I have also been very much involved in the autoimmune neurology section at the American Academy of Neurology.    Dr Berkowitz: So, many of you probably know Dr Pittock - or if you don't know, you've certainly diagnosed diseases that he has described and written about, and so it's a real honor to get to talk to you today and pick your brain a little bit about some of these complex diseases. So, autoimmune neurology is certainly one of the most exciting subspecialties of our field. I feel like when I talk to students and they ask me to make a case for why they should consider neurology as a career, I tell them, “Of course, I have many reasons I love neurology”, but one thing I mention is that, although many other fields of medicine may have made incredible advances as far as treatments, I can't think of too many other fields outside neurology where entirely new diseases have been described since I've been in training and come out of training - and many of those have been in your field of autoimmune neurology. I can think of cases where I've heard you or one of your colleagues on a neurology podcast describing a new antibody, new disease, and a few weeks later, we see that disease and give a patient a diagnosis that had been elusive from other physicians and hospitals. It's a very exciting, gratifying area. It's also daunting, like, every time I go to the AAN and hear one of your colleagues, there's a new disease, and we realize, “Oops! Was I missing that?” or, “Am I going to see this?” And so, hoping to pick your brain a bit today about some of the key concepts and how to keep them in mind so our listeners can recognize, diagnose, and treat these conditions, even if they can't remember every single antibody in your article and all the new ones you and your colleagues will probably discover between now and when this, um, podcast is released. So, before we get into some of the important clinical aspects of these conditions, could you just lay out sort of the broad breaststrokes, the lay of the land of cell-mediated versus antibody-mediated paraneoplastic versus nonparaneoplastic cell surface versus intracellular - how can we sort of organize this area in our minds?    Dr Pittock: Yeah. It's complex, and it's really an evolving story. But the importance, really, from the perspective of the reader and the perspective of the clinician is that we're talking about disorders where we can actually do something - we can actually impact patients.  And we think about the concept of stopping and restoring in neurology now. We're talking about disorders where we have the potential to stop these inflammatory immune-mediated disorders and, potentially, by stopping early, we may be able to restore function - so, a really important new and evolving field in neurology, because you don't want to miss these conditions. Trying to get your head around the complexity of these entities is difficult, but what we've done in this chapter is, really, to try and lay the groundwork for the following chapters, but provide somewhat of a simplistic approach, but a practical approach that really, I think, can help clinicians. So, the way I think of it, a lot of autoimmune neurology really has stemmed from the discovery of antibodies that cause neurological disease, and the examples of those would be going back to myasthenia gravis (with antibodies to the acetylcholine receptor), going back to Lambert-Eaton syndrome. And then, you know, even if you go back to the older traditional paraneoplastic disorders (the Hu, the Ri, the Yo), at the end of the day, you really have two essential entities, if you want to be very simple. The first is disorders that are caused by an antibody, and the second are disorders where the antibodies you detect are not causing the disorder, but they're telling you that there's predominantly a cellular or T-cell mediated attack of the nervous system. And I think thinking about the diseases in those kind of simple terms helps us when we think about what would be the best treatment to use in these types of cases.   Dr Berkowitz: Fantastic. I think that's very helpful. And just to make sure it's clear in the minds of our listeners when we're dividing into these sort of causative antibodies versus antibodies that might be, uh (I don't know if I'm using the word properly), but, sort of epiphenomena (or they're present, but they're not causative) as you said, can you just give some examples of the ones on either side and how making this distinction helps us in practice?    Dr Pittock: Yes. So, antibodies that are causative of disease - I think, you know, the one that I've done a lot of work on is in neuromyelitis optica, where you have antibodies that are targeting a water channel that sits on an astrocyte, and so it causes NMOSD, or what we consider an autoimmune astrocytopathy. And we know that when the antibody binds to the target, many things can happen. So, when aquaporin-4 antibodies bind to aquaporin-4, they can do a lot of things. They can cause internalization, they can activate complement that results in the killing of the cell - but there can be other situations. For example, when NMDA-receptor antibodies bind to the NMDA receptor, then a variety of different things can occur different to water channel autoimmunity - where, for example, the receptor (the NMDA receptor) is downregulated off the cell surface, and that results, to some extent, in the neuropsychiatric phenomenon that we see in NMDA-receptor autoimmunity. And, obviously, when you have a situation where the antibodies are causing the disease, removal of those antibodies, or the reduction in the production of those antibodies, is going to help patients. Now, on the other side, we have antibodies that we detect in the blood or in the spinal fluid, and those antibodies are targeting proteins that are inside the cell - so those antibodies we don't consider as being pathogenic. Now, remember, there are sometimes situations where proteins that are inside the cell occasionally can be available for antibodies to bind at certain situations. So, for example, in the synapse, amphiphysin or the septins, may at times become available. And so, sometimes, there are targets or antibodies that are somewhat in between those two simplistic concepts. But when we're talking about antibodies that are targeting proteins on the inside of the cell, remember that antibodies don't just suddenly occur. There's a whole process of presentation of target antigen at the lymph node, and then both a T- and a B-cell response. The B-cell response potentially produces the antibodies but also triggers and stimulates T-cells, and those T-cells then go on to cause the disease. And those T-cells are very problematic, because those classical paraneoplastic and the newer ones we've described (and many have described) - these are associated with quite severe neurological disability, and they're very, very difficult to treat. And if you ask me, “Where is the holy grail of autoimmune neurology therapeutic research?” It's in trying to actually figure out ways of treating the predominantly T-cell mediated paraneoplastic and autoimmune neurological disorders. We're making great headway in terms of the treatments of the antibody-mediated neurological disorders.   Dr Berkowitz: That's a helpful overview. So, sticking with this framework, you mentioned as sort of the “causative antibody” category and the antibodies that are predominantly for intracellular antigens, but not believed to be causative - I want to make sure I'm understanding this correctly and we can convey it to our listeners - I believe you said in your paper, then, that the antibodies that are predominantly causative are more likely to be associated with conditions that are very treatable, as compared to the intracellular antibodies that are not thought to be causative, as you just said the disability can be irrecoverable or very hard to treat. And I believe another theme in your paper that you brought out is the antibodies that tend to be causative tend to be cell surface and tend to be less likely to be associated with underlying cancer (although not a perfect rule), and the intracellular antigens more commonly associated with cancer in those cases to look very hard for a cancer before giving up. Are those themes that I understand them from your paper properly, or anything else to add there?    Dr Pittock: Yes, I think that that's exactly the message that we were trying to get across, so that's good news that you've picked up on the themes. I think, yeah, in simple terms, remember that when a cytotoxic T-cell identifies the peptide that its T-cell receptor will target, the ultimate outcome is poor, all right? T-cells are like the marines - they don't mess around. Once they find their target, they eliminate that target, and so, it's really difficult to treat those types of diseases if you get them late. And most patients with cytotoxic T-cell mediated paraneoplastic neurological disorders, oftentimes, by the time they get to a center of excellence, the boat has left the dock in many respects - in other words, it's too late. So, you know, I will often see patients, for example, with progressive cerebellar degeneration (say, in the context of Purkinje cell autoantibody type 1 antibodies and a breast cancer), and if those patients are in a wheelchair at the time that I see them, there's very, very little that we can do. So, you really want to try and get that patient into the office, you know, when they're using a cane (or not), and then, potentially, you have the opportunity - using very aggressive immunosuppressive medications - to make a difference. And that is quite different to other scenarios, where, for example, if you have NMDA-receptor encephalitis - as many of the readers will know, this is a condition that is very treatable, and most patients do very well, because the antibodies, they're disrupting function, but they're not killing the neuron, as we see in those more aggressive, paraneoplastic cytotoxic T-cell mediated diseases.   Dr Berkowitz: Also, in terms of searching for an underlying cancer, another theme in your paper as I understood (but want to make sure I'm understanding and conveying to our listeners and hear your thoughts), that the cell surface and treatable antibody-mediated syndromes, as you mentioned (NMO, NMDA) tend to be less associated with underlying cancers (although can be), whereas the intracellular antigens, um, a much higher percentage of those patients are going to end up having underlying cancers. Is that correct, or any notable exceptions to be aware of in that framework?    Dr Pittock: Yeah, I think the major exception to the rule for the antibodies that are targeting intracellular antigens is the GAD65 antibody story. We generally don't consider the stiff person syndrome, cerebellar ataxia, or other autoimmune neurological disorders associated with very high levels of GAD65 antibodies - those are generally not paraneoplastic. And then there are always exceptions on both sides. You know, one of the benefits of understanding the implications of certain antibodies is trying to understand, you know, what is the likelihood of identifying a malignancy, which antibodies are high-risk antibodies (in other words, high-risk paraneoplastological disorders), and which are low risk in terms of cancer? And, you know, age and the demographic of the individual is often important, because we know, for example, with NMDA-receptor antibodies, the frequency of ovarian teratoma varies with the age of the patient.   Dr Berkowitz: Fantastic. And we encourage our listeners to read your articles – certainly, some very helpful tables and figures that help to elucidate some of these broad distinctions Dr Pittock is making - but just to summarize for the antibody-related part of autoimmune neurology, we have one category of cell-surface antibodies and another of intracellular antibodies. Both can cause very severe and varied neurologic presentations, but the cell surface tend to be more treatable, less likely to be associated with the underlying cancer, and the intracellular less treatable, more likely to be associated with the underlying cancer - but, as with everything in neurology and medicine, exceptions on both sides. Is that a fair aerial view of some of the details we've discussed so far, Dr Pittock?    Dr Pittock: Yeah, I think so. I mean, I also think that, you know, not only, at least, for the antibody-mediated disorders (you know, as we discussed) we have drugs that will reduce the production of those antibodies, but we're also learning a lot more about the cytokine and chemokine signatures of these disorders. For example, NMO, water-channel antibody-mediated diseases are associated with elevated levels of IL-6. We know, for example, in LGI1 encephalitis and other encephalitides, that IL-6 also is elevated at the time of that encephalitic process. And so, the potential to target IL-6 with, you know, drugs that inhibit IL-6 and the IL-6 receptor, these potentially have, you know, a role to play in the management of these types of patients - whereas in the T-cell mediated disorders, you know, no advance has been made in the treatment of those conditions, I would say, in over 50 years. So, for example, the standard of treatment is steroids and then drugs that impact the bone marrow, and so we really haven't moved forward in that respect. And that, I think, is an area that really needs drive and enthusiastic out-of-the-box thinking so that we can try to get better treatments for those patients.   Dr Berkowitz: This has been a helpful overview. I look to dive into some of the scenarios that frontline practitioners will be facing thinking about these diseases. An important point you make in your article is that autoimmune and antibody-mediated neurologic syndromes can affect any level of the neuraxis. Even just our discussion so far, you've talked about anti-NMDA receptor encephalitis, you've talked about myasthenia gravis (that's at the neuromuscular junction), you've talked about paraneoplastic cerebellar degeneration - there can be an “itis” of any of our neurologic structures and that “itis” can be antibody-mediated. So, one of the key messages you give us is, one, that these are sort of in the differential diagnosis for any presenting neurologic syndrome, and, two, sort of one of the key features of the history, really, to keep in mind (since we could be anywhere along the neuraxis) is the subacute presentation when this should really sort of be top of mind in our differential diagnosis - so, many of these patients are going to be mystery cases at the outset. And one striking element you bring out in the paper is that, sometimes, the MRI, CSF, electrophysiology studies may be normal or nonspecifically abnormal, and although it's very helpful when we can send these antibody panels out, in some cases, resources are limited or institutions have certain thresholds before you can send these out (because neurologists love to send them in). Sometimes, they are not necessarily appropriate. So, love to hear your thoughts on when we should be sending these panels. What are some clues? Um we have a subacute neurologic presentation at any level of the neuraxis, and when it's not anti-NMDA receptor encephalitis, that is sort of a clear phenotype in many cases. How you would approach a patient, maybe, where the MRI is either normal or borderline abnormal (or people are squinting at the medial temporal lobe and saying, “Maybe they're a little brighter than normal”), CSF is maybe normal or nonspecifically, um, and the protein is a little high, but no cells? What clues do you use to say, you know, “These are the patients where we should be digging deep into antibody panels and making sure these are sent and not miss this diagnosis?”    Dr Pittock: Well, thank you. That's a good question. So, I think, you know, first of all, these are complex cases. So, the patient is sitting in front of you and you're trying to figure out, first of all, Is this a hardware or a software problem? Are we definitively dealing with an encephalitis or an organic neurological entity that's immune-mediated? And, you know, the way I think of it is, for me, you see a patient, it's a twenty-five-piece jigsaw puzzle and you've got two pieces, and you're trying to say, “Well, if I step back and look at those two pieces, do I have any sense of where we're going with this patient?” So, the first thing you need to do is to collect data, both the clinical story that the patient tells you (and I think you make the good point that that subacute onset is really a big clue), but subacute onset, also fluctuating course, sometimes, can be important. The history of the patient - you know, Is the patient somebody who has a known history of autoimmune disease? Because we know that patients that have thyroid autoimmunity are more likely to have diabetes, they're more likely to have gastrointestinal motility or dysmotility, they're more likely to have a variety of different immune-mediated conditions. So, is there a family history or a personal history of autoimmunity? Is the patient at high risk for malignancy? Are there clues that this potentially could be a tumor-initiated immune process affecting the nervous system? The neurological exam also is extremely important because, again, that helps you, first of all, kind of define and get some objectivity around what you're dealing with. So, does the patient have hyperreflexia? Are there signs that there is neurological involvement? And then, really, what I think we need to do is to try and frame the predominant neurological presentation. So, what is the major issue? Because a lot of these patients will have multiple complaints, multiple symptoms, and it's very important to try and identify the major presentation. And that's important, because the neural autoantibody tests are now presentation-defined - in other words, they're built around the neurological presentation, because the old approach of just doing, apparently, a plastic evaluation is gone, because we've got to a stage where we have now so many neural antibodies, you can't test every single neural antibody. So, if you're suspecting that there may be an autoimmune neurological component, then you really need to think about what would be the most appropriate comprehensive evaluation I need to do for this patient. So, for example, if a patient comes in with a subacute-onset encephalopathy, you're probably going to want the autoimmune encephalitis evaluation, and then you have to pick whether it's going to be serum or spinal fluid - and as we outlined in the paper, there are certain antibodies that are better detected in serum versus spinal fluid. So, for example, in adults over the age of 50, LGI1 is much more accurately detected in serum than spinal fluid, and the absolute opposite is true for NMDA-receptor antibody detection. One of the most important components of the neurological evaluation is the spinal fluid, but actually looking at the white cell count - and in fact, sometimes, it's quite interesting to me that I'll often see patients referred with a diagnosis of encephalitis and autoimmune encephalitis, and yet they haven't had a spinal fluid examination. So, the presence of a white cell count, you know, greater than five is hugely helpful - it's like two pieces of that twenty-five-piece jigsaw, because that really tells you that there is something inflammatory going on. And now, in terms of imaging, you're right - some patients will have normal MRI. And if you really do think that there's evidence of - you know, for example, you do an MRI, but you're getting a good sense that there's a temporal lobe seizure occurring, MRI looks normal, the EEG shows some abnormalities in the mesial temporal area - you know, considering additional imaging modalities (like PET scan of the brain), I think, is reasonable. We know that in NMDA-receptor encephalitis cases, 30% of patients will have normal MRI but they'll often have abnormalities on the PET scans. So, I think, what we do is we try to gather data and gather information that allows us to add in pieces of that jigsaw so that, eventually, after we've done this evaluation, we can see now we have ten pieces. If we step back, we say, “Yes, now we know what this condition is”, and then we essentially plan out the therapeutic approach dependent on what we've found. In terms of identification of underlying malignancy, you know, different people have different approaches. Our approach generally has been to try to get a PET-CT scan of the body as our first go-to test, because, actually, we found that CT chest abdomen and pelvis really actually delivers the same amount of radiation - and from a cost perspective, it's about the same - and we have found that PET-CTs really do provide a higher sensitivity for cancer detection.   Dr Berkowitz: Perfect. A lot of very helpful clinical pearls there. So, in closing, Dr Pittock, I've learned a lot from you today. I'm sure our listeners will as well. What does the future hold in this field? What's coming down the pipeline? What are we going to be learning from you and your colleagues that are going to help us take care of patients with these diseases going forward?    Dr Pittock: Well, thank you, Dr Berkowitz, for that question. I think the future is very bright and very exciting, and, hopefully, some of the more junior members will be enthused by this Continuum series, and, hopefully, we'll go into this area. So, let's talk about the future. The future, I think, is going to be of great interest. Firstly, there's going to be continued discovery of novel biomarkers, and the reasons for that is because of the technical and technological advances we've seen. So, for example, there have been many, many antibodies discovered by us and others that have been discovered on the basis of, for example, phage technology. In fact, the Kelch 11 biomarker discovery in collaboration with UCSF and our group was done on the basis of Joe DeRisi and Michael Wilson's phage approach. And we're actually using that now at Mayo Clinic, and we've discovered about three or four new antibodies just in the last couple of years using this technology (and that here is led by John Mills and Div Dubey). And then, we're also going to see, I think, the evolution of protoarrays much more in biomarker discovery, so, we'll have more antibodies, and again, I think, generally, those antibodies will fall into the two categories we kind of described - so, you know, in terms of the approach to those conditions, maybe not so much change. I do think, though, that the introduction and the utility of comprehensive cytokine and chemokine analysis in the future will assist us in making diagnoses of seronegative encephalitis, but also potentially will direct therapy. So, for example, cytokine A is elevated - maybe that would be a potential target for therapy that's available for these patients with rare and potentially very disabling disorders. Then, when we look at the cytotoxic T-cell mediated disorders, I think the major areas of advance are going to be in better understanding the immunophenotype of cytotoxic T-cell mediated diseases, and then the potential development of tolerization strategies using the specific targets, those specific epitope targets that are involved in paraneoplastic and nonparaneoplastic diseases, and seeing if we can vaccinate patients, but move that immune response into more of a tolerogenic immune response rather than a cytotoxic killing response. And then I think, lastly, we're going to see a dramatic revolution in CAR-T therapeutic approaches to these types of disorders moving forward - and not just, you know, CAR-T therapies that are targeting, you know, CD19 or CD20, but CAR-Ts that are actually personalized and developed so that they can target the specific B- and T-cells in an individual patient and actually do a very fine removal of that autoimmune pathologic process that I think would have significant benefit for patients not only in stopping progression, but also in significantly reducing the potential of side effects - so, a much more targeted approach. So, that's where I think the next ten years is going to be. I think it's very exciting. It's going to require the collaboration of neurologists with, you know, immunologists, hematologists, you know, across the board. So, a very exciting future, I think, for this field.    Dr Berkowitz: Exciting, indeed. And we have learned so much from you and your colleagues at the Mayo Clinic about these conditions, and I definitely encourage our listeners to read your article on this phenomenal issue that really gives us a modern, up-to-date overview of this field and what's coming down the pipeline. So, a real honor to get to speak with you, pick your brain about some of the clinical elements, pitfalls and challenges, and also hear about some of the exciting signs.

Today, I'm interviewing Dr Michael Levy on immune-mediated myelopathies, which is part of the February 2024 Continuum issue on spinal cord disorders. Dr Levy is an Associate Professor at Massachusetts General Hospital in Harvard Medical School in Boston, Massachusetts. Welcome to the podcast. Thank you so much for being here today and chatting with me about your article. I really enjoyed reading your article. I read through it, and it felt like, you know, just really enjoyable. I had no concept of time when I was reading it. I encourage all of the listeners to read the article, too. I'll start with just a really broad question, with - what is the most important, clinically relevant thing from your article that you'd like the neurologist listening today to know? Dr Levy: I would say that the group of conditions in which the immune system can attack the spinal cord are growing. We're getting better at identifying the specific antigens, like in the case of NMO neuromyelitis optica and in MOG antibody disease. We're getting better at identifying targets for treatment, like with neurosarcoidosis - identifying those biologics that seem to help. And then, we're even beginning to characterize some of the idiopathic forms, some of which follow covid, or vaccines, or other conditions. I think the message is that we're getting a lot better out there, and if you have a case of inflammation in the spinal cord, then this is something that has a good workup now (and people should be paying attention to articles like this that give them an idea for how to work this up), and then the most appropriate treatment. Dr Nevel: Right. And not to get too much “in the weeds,” but in your article, you really outlined very nicely an algorithm or stepwise approach in evaluating patients with suspected immune-mediated myelopathies. Could you just briefly go through the general principles of that evaluation and stepwise approach, and what you would consider really necessary tests to order for these patients? Dr Levy: Sure. I would say that the first thing that you want to do is to make sure that it's inflammatory. And to do that, we have – the blood tests are few and far in between. If you're dealing with inflammation in the spinal cord, the few ways that we have to convince ourselves that there's truly inflammation - there are MRI and spinal fluid - and those objective tests need to be considered in the appropriate clinical context. The order of events is: patient comes in, reports certain neurological functions that localize to the spinal cord - that's step one, Step two, neurological exam that confirms that there's a neurological problem that localizes to the spinal cord. And then, numbers three, four, five are objective workups, including MRI of the spinal cord and other parts of the neuraxis, CSF testing, and blood testing, all of which then support your differential diagnosis. For each diagnosis, that order is the same, and it should always result in an answer for you, which ultimately may all be negative (and then we have a plan for that, too). If all your workup is negative, you don't know what caused it - at least a plan to deal with that as well. Dr Nevel: Building off of that - in your article, you mentioned that there are shared features between the different immune-mediated myelopathies. We have some tests that can help us differentiate, but what are some of the limitations or strengths of our currently available diagnostic evaluations - our clinical clues to help us differentiate between the different types? Dr Levy: The biggest limitation, of course, is that it's hard to access the spinal cord. We're not going to biopsy almost any patient unless we really have to rule out cancer. Otherwise, we don't want to take a punch out of a very small spinal cord that's carrying a bunch of fibers going in and out of the brain. So, that is our biggest limitation. We can't physically see it under the microscope, so we have to infer what's going on with MRIs and spinal fluid. And of course, spinal fluid isn't necessarily directly in touch with the inflammation - it could just be around it and bathing it. But we're hoping that there are clues from the spinal cord that shed into the spinal fluid that we can detect by lumbar puncture. I do think that we're getting better and also we're identifying things in the bloodstream that could also impact the spinal cord. And of course, blood tests are much easier to do, and some of these blood tests look for antibodies, which we know last for months and months. So, even if a person is having trouble getting their workup done on time, these antibody tests are still useful, even months after onset. Dr Nevel: Yeah. In your opinion, what have been some of the bigger breakthroughs? And I know there's been a lot in immune-mediated myelopathies over, let's say, the past five to ten years. That's a long timeframe, and I know a lot of things have happened during that timeframe – but what do you think has made the biggest impact in either evaluation and/or treatment for these patients? Dr Levy: When I was training, everything in the spinal cord was always MS. It was just - everything was multiple sclerosis in this big bucket of MS that we thought was heterogeneous. Now we're identifying the biomarkers that actually are distinguishing these patients from MS. We know what the immune system is targeting now in many of these conditions. Then, based on that immunological pathway, there are drug targets that have been developed. So, for even a very small disease, with 20,000 people in the US (one in 100,000) who have neuromyelitis optica, we now have three FDA-approved drugs because the science is so well worked out. And now there are two trials in MOG antibody disease, for example. As we identify new biomarkers based on the antigen specificity of the disease, I think we're going to have more and more specific therapies for each of these conditions, even if they're rare diseases. Dr Nevel: Yeah, that's great. Thanks for mentioning those, and I urge the listeners to check out the article to read a little bit more about some of those treatments for NMO spectrum disorder and MOG antibody disease that are in trials. What's the most common mistake that clinicians can make when evaluating or treating patients with immune-mediated myelopathies. What should we watch out for or to try to avoid doing? Dr Levy: I would say, at the beginning, there might be an urge to overtreat because we know that “time is spinal cord” - we don't want to waste time; we don't want to lose time. Some clinicians might just be inclined to give high doses of steroids, even in cases that they're not sure are inflammatory. The big overlap here is especially in older people who might have vascular myelopathy, where steroids might make things worse and it might delay their care. So that's the first problem – is, when physicians rush to judgment. Then the other big problem is when they take their time, and they say, “Well, this is just multiple sclerosis, probably. And we know that, in the end, MS patients do the same whether they're treated or not treated, and so we can take our time with this.” Whereas if we know that this is actually NMOSD, time is spinal cord and destruction is ongoing and potentially irreversible. I would say that there's problems on both sides of the time window. My approach is to be aggressive very early on and try to identify whether or not it's inflammatory. And then if it's not, then you can take a step back and go to the other chapters in this continuum - try to figure out what this is – and if it is inflammatory, then you definitely want to get on top of the treatment. Dr Nevel: Yeah, finding that sweet spot; making sure that you're not waiting too long but that you're not treating inappropriately or the wrong thing. So, what do you think - let's say you have a patient with an immune-mediated myelopathy; you've diagnosed them, they're undergoing treatment. What's the most challenging part of ongoing management of a person who has an immune-mediated myelopathy? Dr Levy: I would say that one of the most satisfying parts of my career lately has been that we're good at preventing the next attack once we know what the disease is. So, for NMO and for MOG and MS, we're good at that. We can suppress the immune system or modulate it in a way that we're preventing the next attack from occurring, and patients are excited about that. But when they come into clinic and I say, “Great job, no new attacks,” then they look at me and they go, “But how do I get out of my wheelchair now?” Because the damage done from prior attacks is not touched by any of these meds. So, there's a huge unmet need in that area of regeneration and recovery of function because, while it's all great that we can prevent the next attack and with all these great drugs that are approved, patients are still suffering. They have mobility problems, bowel/bladder problems, and pain, especially neuropathic pain, that really causes a lot of disability, and that's from damage that's already done. It's the same as spinal cord injury from trauma or from tumors or whatever - the spinal cord injury is the same and there's still a huge unmet need in that area. Dr Nevel: On that note, who else do you usually consider part of the team, if you will - who else should be involved in the management of these patients? Dr Levy: A lot of people. We have urologists involved for bladder, we have physical therapists involved for mobility, and occupational therapy for things related to hand and hand function. We have psychiatrists related to mental illness and also just dealing with these issues, because even if you don't have clinical depression, you still have an adjustment from the disease process and from all the treatments. Social workers, because this is a huge financial burden for a lot of people. An often rheumatologists, because NMO, for example, has about 25 percent overlap with other diseases. We don't want to double treat - we'll often choose a treatment that's applicable to both the rheumatologic disease and the neurological disease. So, I'd say that we don't work alone in almost any case; it's usually quite a big team involved. Dr Nevel: One of the questions that I always like to ask is, what do you think the next big breakthrough is going to be in immune-mediated myelopathies? What's most exciting to you - what do you think is on the horizon here? Dr Levy: I think probably the most exciting area is in multiple sclerosis, where we're starting to understand the role of the Epstein-Barr virus in triggering the disease, and potentially, even in driving the disease. Up to now, we've been suppressing immune systems in people with MS. But maybe we should be looking more at how can we prevent MS from occurring in the first place. And in cases where MS has already started, how does the virus play a role, and can we potentially modulate the outcome of disease with something like antivirals against EBV? So, I think that's the huge, exciting area. It's dominating a lot of the conversations at neuroimmunology conferences. But I think it's well worth the investigation because if MS turns out to be just an Epstein-Barr virus infection, I think a lot of what we've been doing up to now might not be as relevant. So, this is something that's very important. Dr Nevel: Yeah - to have a way to prevent disease rather than treating it after, too, would be a super powerful thing. Dr. Levy: And there are lots of Epstein-Barr virus vaccines that are being developed. But then the question comes up, “Well, are we going to prevent one in a thousand people from getting MS by vaccinating all thousand kids?” Is that really worth it? Can we pick out the ones who are more high risk for developing MS and just vaccinate those kids? A lot of ethical questions involved in that, too. Then what happens if we don't let our population get infected with EBV? We've evolved with that virus for hundreds of thousands of years. What if we abolish it all of a sudden - what does that do? Does it have any implications? I don't know. Dr Nevel: Yeah, lots of really complicated things to think through, with exciting potential but a lot of unknowns. Dr Levy: A lot of unknowns. Dr. Nevel: Talking about patients with seronegative relapsing transverse myelitis - what's your general approach to those patients? When you feel like you've exhausted the extent of your workup but they have a relapsing transverse myelitis, how do we approach those patients and take care of them? Dr Levy: “Seronegative” refers to patients who test negative for aquaporin-4, which is NMO, and test negative for MOG antibody disease (so they are double seronegative), but they have a recurring disease that looks an awful lot like one of the two. We generally stratify these patients into the “aquaporin-4-like,” “MOG-like” or “MS- like.” So, we try to put them into a category even if they're seronegative because we think that the treatments would be the same. So, for the MOG-like, for example: these are patients who have recurring attacks; they're not necessarily all long, but they do tend to remyelinate, and they can be severe at first but then they do get better over time. That's “MOG-ish,” so we treat those people with MOG treatments. Whereas people who have this sort of aquaporin-4 type, they have severe attacks and they really don't get better, and they have a lot of necrosis if you look at it under the microscope. And those people we tend to treat with aquaporin-4 NMO drugs. And then we have the MS type that kind of lingers or is more focal white matter lesions. Even if they don't have a lot of brain lesions, they might be oligoclonal band-positive; we put them in the category of MS. But we have a very active research effort to identify new antibodies in case any of these diseases that are seronegative and don't fit into any category - it's certainly possible that there's an antigen of their own that they're attacking, so we'd like to try to identify that in these novel assays that we're doing in the lab. Dr Nevel: How do you counsel patients on what to expect in the future, who you're seeing in the hospital with their first episode of transverse myelitis, for whatever the cause? Because one of the biggest questions I suspect most patients ask is, “Am I going to get better? Is this going to happen to me again?” How do you navigate those tough discussions, and what do you tell patients? Dr Levy: In the hospital, it's tough, because a lot of our testing takes time - it takes ten, fourteen days. So, in the hospital, I say, “Look, we're going to focus on here and now - we're going to suppress the inflation; we're going to try to get you better from this event.” It could have been a severe optic neuritis or transverse myelitis, or brain stem injury, or whatever - we're going to try to focus on that. And then I say, “When you come back to my clinic, we'll have the results from all of your testing and we're able to talk about the future and how to prevent the next one, if we have to.” It does take time, unfortunately, to get all that data back, and it is a little bit suspenseful for patients, but that's what we have at the moment. Dr Nevel: Yeah, the most honest answer that you can give them is always the best one. And that's the scenario when you're in the hospital - that there just isn't full answers. Dr Levy: Yeah. One of the reassuring things I can say is, “We have a lot of medications that target different parts of the immune system, so no matter what you have, we can probably treat it.” Dr Nevel: Right. Obviously, really important to give people a sense of hope and reassurance that you're there and you're going to help find a treatment that's going to help them in the future. Well, thank you so much for chatting with me today. I really enjoyed our conversation and reading your article and learning more about immune-mediated myelopathies. Dr Levy: It's been a pleasure.

For this “ABCs of NMOSD” episode titled, “Transitioning from Pediatric to Adult Care with NMOSD,” Dr. Jonathan Galli joined Krissy Dilger of SRNA. Dr. Galli provided insights into the disorder and its presentation across age groups, emphasizing the importance of aggressive treatment [00:01:35]. He highlighted differences in treatment approaches and medication availability between pediatric and adult populations [00:05:54]. The discussion also explored the transition process, including timelines, support systems, and considerations for patients and families, aiming to ensure a smooth shift in care [00:10:45]. Dr. Galli received his medical degree from the University of Vermont College of Medicine in Burlington, VT, and completed his neurology residency at The University of Utah in Salt Lake City, UT, where he worked with Fellowship mentor, Dr. Clardy. As part of his fellowship training, he conducted research to look for biomarkers in individuals with NMOSD. The research investigated whether individuals have aquaporin¬-4 (AQP¬4) autoantibodies prior to their symptom onset of NMOSD, and also looked for other inflammatory biomarkers. He hopes the study will help us to understand how biomarkers occur over the course of the disorder, which will hopefully help identify predictors of disease development, and ultimately therapeutic targets.

Ever felt that strange mix of relief and grief when you finally know what you're up against? That's exactly what Brooke went through upon receiving her daughter's diagnosis of neuromyelitis optica spectrum disorder (NMOSD). It opened up a whole new chapter, not just for her daughter but for the whole family. This episode shines a light on the complex emotions involved in coming to terms with a chronic condition.

The “Community Spotlight” edition of the “Ask the Expert” podcast series shares the stories of our community members. This episode is part of a special series on grief and loss. Lisa McDaniel joined Krissy Dilger of SRNA to share about her family's experience with neuromyelitis optica spectrum disorder (NMOSD). Lisa McDaniel's awareness of rare disease began in 2007, after the onset of neuromyelitis optica spectrum disorder (NMOSD) in her 5-year-old son, Collin. She learned what it took to be a “Rare Mom” and fought for her son's life. After Collin's passing in 2012, Lisa switched gears and went to work for the Guthy-Jackson Charitable Foundation (GJCF), where she is now the Director of Patient Advocacy. She now uses her extensive caregiver experience to help other patients and families living with NMOSD. Through GJCF, Lisa is able to engage with the NMOSD community to provide resources, information, and education, as well as lead support groups and raise awareness of rare diseases through educational events.

Sumaira Ahmed is a force! Upon being diagnosed with a rare neuroimmune condition (Neuromyelitis optica spectrum disorder/ NMOSD, whose symptoms can include vision loss, paralysis, and weakness), Sumaira couldn't find the community she needed, so she went right ahead and launched a foundation (two months later!) to create that support for herself and patients around the world. The Sumaira Foundation has since advocated for patients, funded disease research, increased NMO awareness globally and truly been a game changer in the field. Hear how this young dancer and Bollywood aspirant (who was crowned the first Miss Bangladesh-USA) turned into a fearless non-profit leader and champion for patients suffering from this rare disease.Join me with the wonderful Sumaira - now on your favorite podcast app, Spotify or iTunes and please please take a second to rate us wherever you're listening so the voices of these inspiring women can be heard all over the world!SHOWNOTES FOR EPISODE 88:Read more about Sumaira's work at The Sumaira Foundation and connect with her and The Sumaira Foundation on InstagramInfinite Vision: How Aravind Became the World's Greatest Business Case for CompassionQuestions?

Christine Ha, an award-winning blind chef and restauranteur, shares her experience grappling with neuromyelitis optica spectrum disorder (NMOSD). Facing relapses with the inability to walk and feed herself that challenged her independence, she leaned on the support from family and friends. As she lost her sight due to optic neuritis in both eyes, Ms. Ha had to embark on a journey of rediscovery in the kitchen, starting with the fundamentals. Winning MasterChef Season 3 marked a turning point, propelling her culinary career forward despite the obstacles posed by her disability.  NMOSD is an autoimmune disease in which an antibody attacks water channels on astrocyte cells in the optic nerves, spinal cord and sometimes the brain. Attacks or relapses can be devastating and incomplete recovery from attacks is typical. Like Ms. Ha, some people living with the condition can be misdiagnosed with multiple sclerosis. A blood test for the aquaporin-4 antibody is key to getting diagnosed correctly early. Since 2019, highly effective treatment options have been FDA-approved that reduce relapses by 77-94%. Barry Singer MD, Director of The MS Center for Innovations in Care, interviews: Christine Ha, "The Blind Cook".  Her first cookbook, Recipes from My Home Kitchen, was a New York Times best-seller. Ms. Ha's first restaurant in Houston, The Blind Goat, was named a semi-finalist for 2020 Best New Restaurant in America by the James Beard Foundation. She was also named a James Beard finalist for Best Chef in Texas in 2022.

Krissy Dilger of SRNA was joined by Drs. Drs. John J. Chen and Elias S. Sotirchos for an “Ask the Expert” podcast episode titled “Acute Treatments and Rare Neuroimmune Disorders.” The experts began by providing an overview of treatments for an acute demyelinating attack and how they are administered. They also discussed side effects, safety concerns, and the decision process for escalation. Finally, the experts shared age considerations and upcoming research. John Chen, MD, PhD attended the University of Virginia for his undergraduate and combined MD/PhD degrees. He completed his Ophthalmology residency and Neuro-Ophthalmology fellowship training at the University of Iowa. He then took a position at the Mayo Clinic in 2014 where he specializes in Neuro-Ophthalmology. Currently, he serves as a Consultant and Professor of Ophthalmology and Neurology, and Neuro-Ophthalmology Fellowship Director at the Mayo Clinic. Among Dr. Chen's awards/honors are the AAO Achievement Award, resident and fellow teaching awards at the University of Iowa, Ophthalmology Teacher of the Year Award three times at the Mayo Clinic, 2023 Mayo Clinic Distinguished Educator Award, Top Doctors in Minnesota, and the Heed Fellowship. He is a board member for the North American Neuro-Ophthalmology Society and is on multiple committees for the AAO, co-chairs the Upper Midwest Neuro-Ophthalmology Group, is a member of the American Ophthalmological Society and American Eye Study Club, previously served as the President for the Minnesota Academy of Ophthalmology and participated in the AAO and AUPO Leadership Development Programs. He has over 200 peer-reviewed publications, has received several research awards, and is currently RO1 funded through the NIH. He has given over 200 oral presentations, including multiple named lectureships, and visiting professorships, on his interests in ophthalmic imaging, idiopathic intracranial hypertension, and optic neuritis, especially NMOSD and MOG antibody-associated disease. Elias Sotirchos, MD is a neurologist at Johns Hopkins Hospital in Baltimore, Maryland. He specializes in the diagnosis, management, and treatment of neuroimmunological disorders that involve the central nervous system, including multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), and myelin oligodendrocyte glycoprotein-immunoglobulin G (MOG-IgG)-associated disorder (MOGAD). His research focuses on developing and validating novel imaging and blood-based biomarkers of these conditions, and clinical trials of experimental therapeutic agents.

In this episode of the podcast we discuss neuromyelitis optica spectrum disease (NMOSD), a rare autoimmune disease that effects central nervous system function and can result in symptoms such as pain, vision loss, limb weakness and numbness. Joining us are Dr. Maggie Kang and Nell Choi, mother and daughter patient advocates who talk about NMOSD and their experiences since Nell was diagnosed at a young age.
