Monogenic Mimics of Neuroinflammatory Phenotypes in Children and Young Adults - Part 1 01/09/2026

Monogenic Mimics of Neuroinflammatory Phenotypes in Children and Young Adults - Part 1 In part one of this two-part series, Dr. Stacey Clardy and Drs. Ayush Gupta and Kuntal Sen discuss the key clinical features that should shift suspicion from autoimmune encephalitis or demyelinating disease to monogenic mimics.

Published 2025 Nov 25. doi: Show transcript: Dr. Stacey Clardy: Hi, this is Stacey Clardy from the Salt Lake City VA in the University of Utah. For a two-part podcast series, I've been speaking with Ayush Gupta from the University of Nebraska Medical Center and Kuntal Sen from Children's National Hospital in Washington DC about the monogenic disorders that mimic neuroinflammatory disease that are lurking in all of our clinics just waiting to be diagnosed. Ayush, for the minute, when you're seeing a patient with a presumed autoimmune encephalitis or demyelinating disease, what single cluster of features should instead most strongly push us to think of monogenic mimics at the top of our differential? Dr. Ayush Gupta: So when you are seeing a patient with presumed autoimmune encephalitis or a demyelinating disorder, cluster of features such as earlier onset in terms of age, developmental delays, CSF or imaging finding that's non-concordant with the diagnosis such as a non-inflammatory CSF, a symmetric white matter or deep gray matter involvement and relentless progression despite immunotherapy, these are the red flags where you should stop, seriously consider the possibility of a monogenic disorder and reach out to help from colleagues. Dr. Stacey Clardy: That's a great list, and we get into far more detail in the two-part podcast series. So please listen to both of those and take a read of the neurology genetics review titled Monogenic Mimics of Neuroinflammatory Phenotypes in Children and Young Adults: An Evolving Landscape. /episode/index/show/neurologyminute/id/39652760

Epilepsy Behav. 2020;103(Pt A):106861. doi: Show transcript: Dr. Neishay Ayub: Hello, my name is Neishay Ayub, and today we are discussing the history of a novel anti-epileptic drug, levetiracetam. It's a story of a scientific dead end, a radical new testing method, and a mystery that took years to unravel. To set the scene, let's go back to 1974. The pharmaceutical company, UCB Pharma, was working on compounds to boost cognitive function. They were looking for a successor to their drug piracetam. During this research, levetiracetam was first synthesized, but the compound didn't show any significant brain-boosting effects. With no discernible purpose, it was filed away and largely forgotten. For nearly two decades, this medicine sat on a shelf an anonymous entry in a long list of failed drug candidates. The story could have ended there, but in the early 1990s, researchers took a different approach to drug discovery. Researchers screened their entire library of forgotten compounds against audiogenic seizure-susceptible mice. These are mice prone to seizures triggered by sound. Levetiracetam was incredibly ineffective in chronic epileptic mice. Interestingly, levetiracetam had previously failed traditional screening tests which was to prevent acute seizures in normal animals subjected to maximal electroshock or pentylenetetrazole. Levetiracetam was pushed forward to human clinical trials and was found to be efficacious in three placebo-controlled, randomized, blinded clinical trials for adults with refractory focal epilepsy. Two of the clinical trials reviewed levetiracetam three grams per day compared to placebo. They found the responder rate, i.e., 50% reduction in seizure frequency, was 39% to 42% for patients on three grams per day versus placebo at 10% to 16% when used as adjunctive therapy. One of these trials also used levetiracetam as monotherapy, noting a median percent reduction in focal seizure frequency of 73%, a responder rate of 59%, and 18% of patients achieving seizure freedom. In November 1999, the FDA gave its approval for adjunctive treatment of partial onset seizures. While levetiracetam was effective, how it worked was still unclear. It didn't affect the ion channels and neurotransmitter receptors that older, more traditional anti-epileptic drugs targeted. Eventually in 2004, scientists made another breakthrough. They identified the drug's primary molecular target, a protein called SV2A. This protein is involved in regulating the release of neurotransmitters. Instead of suppressing all neurologic activity, levetiracetam appears to bind to SV2A and selectively modulate neurotransmitter release in overactive seizing neurons. This precise mechanism is why it has such a favorable side effect profile. With the mystery solved and a novel mechanism understood, levetiracetam continues to be a popular anti-seizure medication to this day, and its use has been expanded. Further clinical trials led to FDA approvals for use in adult and pediatric patients with myoclonic epilepsy for myoclonic seizures as well as adult and pediatric patients with idiopathic generalized epilepsy for primary generalized tonic-clonic seizures. There is an off-label use for status epilepticus and seizure prophylaxis in TBI, in traumatic brain injury, subarachnoid hemorrhage, and neurosurgical cases. Formulations have also expanded to include tablets and liquid formulations for immediate release, extended-release tablets, and intravenous formulations. Today, with the original patent expired, generic versions are available, making this treatment accessible to millions. The journey of levetiracetam from an abandoned compound to a frontline treatment is a powerful reminder that in science, a failure might just be a success waiting to be tested in a different way. /episode/index/show/neurologyminute/id/39651735

January 2026 President Spotlight: What to Expect in 2026 01/05/2026

January 2026 President Spotlight: What to Expect in 2026 In the January episode of the President's Spotlight, Dr. Jason Crowell and Dr. Natalia Rost discuss AAN’s plans for 2026, including a general neurology boot camp, Autoimmune Conference, and new resources for members. Stay informed by watching the . Show transcript: Dr. Jason Crowell: Hello, and welcome to today's Neurology Minute. This is the first installment of 2026 that we have with the president of the AAN, Natalia Rost. Natalia, thanks so much for joining us today, we look forward to our monthly chats to talk about things going on with the AAN. Before we start talking about the plans for 2026 with the American Academy of Neurology, what are the things that are on your mind? Dr. Natalia Rost: Happy new year, Jason, great to join you today. Well, first of all, I think 2026 is going to be a strong year, and as I think what's coming down our pipeline, it's our work to promote brain health and to support neuroscience research. It's the fight that we have to fulfill Medicare payments, and to protect patient access to care. Our efforts to advance physician-led neurology teams and to reduce burnout. And to always stand firmly for science and evidence-based medicine. Dr. Jason Crowell: Now, I know every year the AAN has new programming and content that they're putting out, what's going to be in store for 2026? Dr. Natalia Rost: First of all, we're launching a brand new general neurology bootcamp at the annual meeting, high impact learning, real connections, and great energy guaranteed. Also back by popular demand, the Autoimmune Conference will take place again this summer, featuring all the latest science, so I'm excited about that. For our advanced practice provider members, expect a new online toolkit to improve your neurology knowledge and patient care skills. For our residents, we are adding a new pediatric neurology option for our RITE exam lineup. And last but not least, we are fully reimagining our patient education on brainandlife.org, because as you know and as our members know, an informed public makes powerful partners in our Brain Health For All movement. Dr. Jason Crowell: Terrific. And so, are there any efforts from last year that will continue to be a focus for this coming year? Dr. Natalia Rost: Two things immediately come to mind, and our work will only grow stronger there. Number one is to continue to modernize our digital platforms and provide resources to our members to tackle AI and emerging technologies. As you know, this is a big issue. And number two is to advocate relentlessly for fair reimbursement and access to care. Our advocacy is only going to grow stronger in 2026. Dr. Jason Crowell: So, Natalia, most of us are still working to keep our New Year's resolutions intact, I'm a few days into my exercise program, we'll see how long that goes. But what would you say are the New Year's resolutions, if you will, for the AAN? Dr. Natalia Rost: Well, this year is going to be the year to fully embrace our Brain Health For All approach, I think. Neurologists are the experts in brain health, so our promise is for the AAN to continue tirelessly support our members so they can lead, care, and thrive as they do. Dr. Jason Crowell: Terrific, Natalia. Thanks so much. Happy New Year again. Dr. Natalia Rost: Happy New Year. /episode/index/show/neurologyminute/id/39617580

Show citation: Tolchin B, Goldstein LH, Reuber M, et al. Management of Functional Seizures Practice Guideline Executive Summary: Report of the AAN Guidelines Subcommittee. Neurology. 2026;106(1):e214466. doi: Show transcript: Dr. Mahinda Yogarajah: Welcome to this edition of Neurology Minute. I'm your host for this. My name's Mahinda Yogarajah. I've just finished interviewing Dr. Ben Tolchin and Jon Stone for this week's Neurology® Podcast. For today's Neurology Minute, I'm hoping Ben can tell us the main points of the podcast and the paper discussed in that podcast. Dr. Ben Tolchin: We discussed the AAN guideline on the Management of Functional Seizures. This is the first American Academy of Neurology evidence-based guideline on functional neurologic disorder. It includes a systematic review of the randomized controlled trials relating to the treatment of this disorder, which found that psychological interventions are possibly effective in improving the chance of achieving freedom from functional seizures, in reducing the frequency of functional seizures, in improving quality of life, and in improving anxiety. In addition to the systematic review, there are clinical recommendations based on the systematic review and on related evidence. The recommendations deal with all stages of the diagnosis, management, and treatment of functional seizures and are particularly relevant to neurologists caring for patients with functional seizures. In addition, there are recommendations for future research relating to the diagnosis and management of functional seizures. Dr. Mahinda Yogarajah: Thank you, Ben. For more information, I'd recommend go to the main podcast or go and have a read of the article that's been published in Neurology® on the Management of Functional Seizures Practice Guidelines. /episode/index/show/neurologyminute/id/39529035

Functional Neurologic Disorder Series - Part 7 12/24/2025

Functional Neurologic Disorder Series - Part 7 In the final episode of this seven-part series, Dr. Jon Stone and Dr. Gabriela Gilmour wrap up the conversation discussing future directions. Show citations: Finkelstein SA, Carson A, Edwards MJ, et al. Setting up Functional Neurological Disorder Treatment Services: Questions and Answers. Neurol Clin. 2023;41(4):729-743. doi: Show transcript: Dr. Gabriela Gilmour: This is Gabriela Gilmour with the Neurology Minute. Jon Stone and I are back for our final episode of our seven-part series on functional neurological disorder. Today, we will discuss future directions for the field of FND. So Jon, where do you see the field of FND going in terms of diagnosis and treatment? Dr. Jon Stone: So we've seen a tremendous increase in interest in FND, particularly in the last five years since we started the FND Society. I think there's much more awareness of making rule-in diagnoses compared to before. There's much more positivity about treatment and I think people who experience their own patients doing very well with treatment makes them want to see that again. But we've got a long way to go. I think the diagnostic ruling features that we talked about in an earlier episode are still largely clinical. I think we could really benefit from seeing those becoming more laboratory supported, particularly for research, particularly for looking at FND comorbidity and other neurological conditions like MS and Parkinson's. So I think we might see more of that, AI helping us with that maybe, but things like quantifying some of the physical signs that we use. In terms of treatment, I think it's great all the different ideas about treatment that we've had and we know that the rehabilitation therapy for FND benefits from a more FND focused approach. But we have to be honest as well and say that the treatments, there's still large numbers of patients who are not improving. And so we do need to think about other ways to help people. People are interested in treatments, modalities such as using virtual reality, people looking at medications such as psychedelics or things like that. We've got to be careful with that obviously in peoples where their brains don't work properly. But I think we can do better than we are and people are exploring those options interestingly. Dr. Gabriela Gilmour: Yeah. And I think on the note of treatment, as we've sort of spoken through this podcast series, we've talked about places or environments where there's already services set up for patients. And so I think another major goal for the future for the FND Society is to build more services and have more expertise and knowledge across the world. What would you tell neurologists to do or how would you support them if they don't have other health professionals to help in their local environment? Dr. Jon Stone: Well, I'm aware that that's probably what most neurologists feel like. That they can recognize FND, but they don't have people to refer to or therapists who know about FND. So I certainly share that frustration. What I would say has happened locally here in Edinburgh, and also I see this in other centers as well. If you just start referring patients, helping to send patients to your colleagues who want to have therapy, educating your colleagues, then the people around you can develop that expertise that's needed. You don't necessarily need a whole new team. If you're an enthusiastic neurologist interested in FND, be careful about doing it just on your own because I think there's a lot of good you can do, but it'd be quite easy to burn out there without some help. So I think it's a slow process of gathering together interested health professionals. Ideally, of course, you want to have a psychologist to do therapy, a psychiatrist for more detailed assessments of complex patients, physio, OT, speech and language therapy. Once you get that, what I find is that then locally, they will start to teach each other because this is work that most people in rehabilitation actually enjoy when they know how to do it. They like seeing people with FND. They like the fact that this is a disorder that will often be static for many years or a long time anyway, and where therapy can actually change that trajectory. So just sort of hang in there. There are articles you can read about more details about how to set up services and think about that as well. Dr. Gabriela Gilmour: Well, thank you so much, Jon, for joining me for this series. This is our final episode of the Neurology Minute series on Functional Neurological Disorder. And thank you to all of our listeners. Dr. Jon Stone: Thank you very much, Gabriela. /episode/index/show/neurologyminute/id/39528930

Functional Neurologic Disorder Series - Part 6 12/23/2025

Functional Neurologic Disorder Series - Part 6 In part six of this seven-part series on FND, Dr. Jon Stone and Dr. Gabriela Gilmour discuss the prognosis of functional neurologic disorders. Show citation: Gelauff J, Stone J. Prognosis of functional neurologic disorders. Handb Clin Neurol. 2016;139:523-541. doi: Show transcript: Dr. Jon Stone: This is Jon Stone with the Neurology Minute. Gabriela Gilmour and I are back to continue with part six of our seven-part series on FND. Today we're going to talk about prognosis. What's the outlook for people with FND? It's obviously a question that patients and relatives desperate to know the answer. Gabriela, what do you say to your patients with FND when they say, "What's going to happen to me? Dr. Gabriela Gilmour: That's a difficult question because the prognosis is variable and I'll talk in a moment about what we know about prognosis from the literature. But I think when patients ask me what's going to happen, I try to instill hope because we do know that this is a condition that can improve and it can improve, especially when patients have access to rehabilitation programs or psychotherapy or other treatment plans. So I try to emphasize that piece and emphasize hope when I'm talking about that with my patients. But if we sort of take a step back and we look at what is the overall prognosis from what we know in the literature with FND, fundamentally, FND for many is a chronic and often relapsing condition. As I mentioned, it can certainly improve with rehabilitation. A challenge is that most of our published studies on the prognosis of FND really come from a time when we knew a lot less about the condition and we had fewer treatment options. So these studies are somewhat difficult to apply today, but in these studies, we see that at least without treatment, most patients are the same or worse at follow-up. However, now we're starting to develop more rehabilitation programs and we have more evidence that shows that people certainly improve with rehabilitation and with therapy. There are some factors that I try to emphasize to patients as being good prognostic factors when I'm talking with them. These may be things like younger age, a shorter duration between symptom onset and diagnosis and patient agreement with the diagnosis or the perception of having control over their illness. When these types of things are present, I try to highlight them to, again, help build that hope for recovery. The one thing that I would also add maybe a bit of a different question, but I think is important to mention is that we as neurologists still have a lot to provide to our patients, even those who may not see much recovery in their symptoms and live with chronic illness. It's really important to consider that regular check-ins. In these check-ins, we can monitor for changing perpetuating factors. We can facilitate social services, mobility aids that help overall quality of life. We can still offer a lot to our patients. The other piece that I would mention too is that our patients are at risk of iatrogenic harm. So there is definitely a role for the neurologist to look at, are there medications that might not be indicated that are causing harm? Are there other things that we can communicate clearly with other care providers to make sure that we reduce that risk for our patients? Dr. Jon Stone: So it's about balancing some realism, but also making sure the patient doesn't lose hope. A good outcome isn't always necessarily that symptoms gone away. It might be similar to other chronic neurological conditions that we look after where we're okay with an outcome where the patient still has symptoms if they understand their condition and can learn to live with it better. We'll be back for our final Neurology Minute episode on FND with myself and Gabriela Gilmour talking about future directions in FND.

Neurology. 2026;106(1):e214466. doi: Show transcript: Dr. Jon Stone: Hello, this is Jon Stone with the Neurology Minute. Gabriela Gilmour and I are back to continue with part five of our seven-part series on FND. Today we'll be discussing treatment. Gabriela, talk us through what the rehabilitation or therapy approaches exist for FND now. Dr. Gabriela Gilmour: I would start actually even before jumping into rehabilitation and therapy to again emphasize something that we talked about in the last episode, which is that rehabilitation very much starts at our first visits with our patients when we examine for positive signs and show these to our patients and explain what they mean. So education about FND is really a fundamental treatment step, and I think we as neurologists have so much to offer to our patients in these visits. Next, when we're thinking about rehabilitation for FND, this often includes some combination of physical rehabilitation and psychological therapy and really should be individualized to each patient. So multidisciplinary or integrated therapy approaches are the gold standard and treatment strategies with these are really guided by our evolving understanding of the mechanisms of FND. So for example, this means using strategies like distraction, motor visualization, relaxation and mindfulness to target that underlying mechanism of FND. And then we use psychological therapies to also address perpetuating factors. So as we have discussed in this series, patients often experience many symptoms. So we also want to think about those other symptoms in our treatment plan, whether that be chronic pain or sleep disturbance or treating comorbid psychiatric or neurological illness. When we think about the subtypes of FND, there is some research into specific strategies for each. So psychotherapy, in particular, cognitive behavioral therapy is the focus for functional dissociative seizures with strategies aimed at attack prevention. Whereas for functional movement disorder, motor retraining physiotherapy has the most evidence. One big thing that I want to emphasize though is that rehabilitation for FND really relies on patient self-management and patient engagement. So I often explain to my patients that I can't retrain their brain, but I can help support them in this process and doing this for themselves. Dr. Jon Stone: So when you meet a patient with FND, how do you decide whether therapy is going to be helpful for them? I think people often have a tendency to say, "Oh, it's FND right off you go to psychotherapy or physiotherapy," but is that always the right option? How should we try and help our patients to decide if it's the right time for them to do these treatments? Dr. Gabriela Gilmour: Yeah, I think that that's something that's really maybe not unique, but something that's really important to FND and to treatment planning and FND. When we're supporting our patients as they embark on a treatment pathway, we really want to set them up for success. And so this really does rely on a robust triage process. So unlike other neurological conditions where you have X disease, therefore, why is the treatment? For FND, we've got a host of different types of treatments, and we want to individualize that and we want to time it right. Fundamentally, we really want to select the right treatment for our patients, and that relies on us understanding what symptoms are most bothersome to our patients, and we want to then provide that treatment at the right time. And I think right time is really what I would emphasize as being so, so important. So this means that patients are ready for active participation and rehabilitation, they're enthusiastically opted in. They think that treatment's going to help, and there aren't major barriers that are going to impact their ability to participate fully, so things like severe pain that could get in the way. And this is a conversation that I have really openly with my patients, and I really try to let them guide the timing. They will let me know, "Hey, I'm a teacher, and I'm in school right now. Now is not the right time for me to embark on this, but what about in June or July?" And then we revisit and regroup at that time. So really I do let my patients guide this process, but I would say that there are a subset of patients that don't need these more advanced rehabilitation type programs. Maybe are spontaneously improved or are able to implement some of their own self-management strategies on their own and have a significant improvement in symptoms already. Dr. Jon Stone: We need to make it easy for our patients to tell us when it's not the right time, but also, there's no one-size-fits-all, basically. Dr. Gabriela Gilmour: Absolutely. Dr. Jon Stone: So we'll be back for more Neurology Minute to continue our discussion on FND. We'll be talking about prognosis. Thanks for listening. /episode/index/show/neurologyminute/id/39504085

My name is Zohaib Siddiqi and I'm a fifth-year neurology resident and a part of the Neurology® Resident and Fellow Section Editorial Board. I just finished interviewing Catarina Bernardes about her article, Clinical Reasoning: A 35-year-old Woman with Personality Change and Gait Impairment. Catarina, can you tell us the main points of the article? Dr. Catarina Bernardes: So in this article, we discussed the case of a 35-year-old woman who presented with a three-year history of walking difficulties. On examination, she had signs of a frontal temporal dysfunction, a dorsal lateral myelopathy, optic atrophy, and pes cavus. Her brain and spinal cord MRI was completely normal, but her son's brain MRI was being studied for spastic paraparesis showed signs of hypomyelination involving the subcortical U fibers. Given the suggestive inheritance pattern, we considered an X-linked leukoencephalopathy and central nervous system hypomyelination points to Pelizaeus-Merzbacher disease. Important learning points. When differentiating leukoencephalopathies, remember that hypomyelinating disorders often have less pronounced hypointensity on T2 and hypointensity on T1, and in demyelinating disorders, there is very prominent hyperintensity on T2 and hypointensity on T1. Also, Pelizaeus-Merzbacher is a hypomyelinating disorder affecting the subcortical U fibers, while X-linked adrenoleukodystrophy presents a demyelinating pattern sparing the subcortical U fibers and involving mainly the parietooccipital regions. Dr. Zohaib Siddiqi: Thanks so much for that summary, Catarina. A lot of learning points there. For those of you who want to learn more about the case, you can listen to the full-length podcast available now on all streaming platforms and find the article titled, Clinical Reasoning: A 35-year-old Woman with Personality Change and Gait Impairment on the Neurology® Resident Fellow Website.

Jon Stone and I are back to continue with part four, of seven, of our series on functional neurological disorder. Today we will focus on the diagnostic explanation. So many patients have never heard of FND before receiving this diagnosis. Can you share how you explain the diagnosis to your patients? Dr. Jon Stone: So I'm aware that many neurologists do find this difficult. And I have to say, having thought about it for 20 years or so now, I think the answer is, don't be weird. Do what you normally do with any condition, when you explain it to patients. I think what goes wrong is that people see FND as something weird and other, and they start to do weird things like telling people that their scans are normal, or telling them what they don't have before they've started to tell them what they do. If you go with the normal rules of explanation, first of all, starting by giving it a name that you prefer, so you've got FND, or try and be specific if you can. You've got functional seizures, functional movement disorder. Give it a name to start with. Don't sort of spend a long time beating around the bush before you do that. Talk a bit about why you've made the diagnosis, because that's what you normally do. So if someone's got a weak leg, show them their Hoover's sign. I think actually showing people their physical signs is probably one of the most powerful things you can do, brings the diagnosis away from the scanner and into the clinic room. And also, they can see in front of them the potential for improvement. So it feeds forward into treatment. Yes, you might need to explain why they don't have some other conditions that they're worried about, but you can leave discussions about why it's happened for later. I think what tends to go wrong is people jump into that too early. So the bottom line, just do what you normally do and things generally go a lot more smoothly. Dr. Gabriela Gilmour: And when you're providing the diagnostic explanation, it can be really helpful to link the patient's experience and their symptoms to the diagnosis. And so, I wonder how you integrate that piece into your diagnostic explanation, or how you tailor your explanation to an individual patient. Dr. Jon Stone: Yeah, I think tailoring is really important here. And this is where obviously if you've done your assessment, so helpful to ask the patient is, "Well, what do you think's wrong? What things were you worried about? " Some people say, "Look, I'm really worried I've got MS." Or some people say, "I haven't got FND. I've read about that. " Or sometimes people are wondering if they've got FND. So, you've got to try and tailor it to what the person is expecting and particularly previous experiences. If they're telling you how angry they were about doctors A, B, and C, then obviously you want to use that and try not to end up with the same outcome. Why would there be a problem with this diagnosis? It's because they haven't heard about it, because they've got misconceptions about it. Do they feel that this diagnosis would be saying it's all in their mind or something like that? You might need to be explicit about that. But I think this links into how, it's not just about the diagnostic label, it's about a formulation, which is something we don't think about much in neurology. So there's a label for what's wrong, but in FND, a formulation, why have you got FND, in your particular case, is what we're sort of moving on to there based on the story that you've heard. Dr. Gabriela Gilmour: Yeah. And I think in my experience and in working with trainees, really just practicing, saying it, is so important and saying it in a way that feels honest and correct to you as a clinician. Dr. Jon Stone: Yeah, absolutely. Dr. Gabriela Gilmour: So we will be back for more Neurology Minute episodes to continue our discussion on FND. Next, we're going to be talking about treatment.

Functional Neurologic Disorder Series - Part 3 12/17/2025

Functional Neurologic Disorder Series - Part 3 In part three of this seven-part series on FND, Dr. Jon Stone and Dr. Gabriela Gilmour discuss causes of functional neurologic disorder. Show citation: Hallett M, Aybek S, Dworetzky BA, McWhirter L, Staab JP, Stone J. Functional neurological disorder: new subtypes and shared mechanisms. Lancet Neurol. 2022;21(6):537-550. doi: Show transcript: Dr. Gabriela Gilmour: This is Gabriela Gilmour with the Neurology Minute. Jon Stone and I are back to continue with part three of our seven-part series on functional neurological disorder. Today, we will focus on the causes of FND. So Jon, there have been many advances in our understanding of the mechanism of FND in the last 10, 15 years. And so what do we know about this now? Dr. Jon Stone: I think the key message I want to get across here is that whereas previously we had a very psychiatric, purely psychiatric view of FND, it used to be called conversion disorder, what we've got now is a multi-perspective view of the mechanisms, which mean that we can understand FND at a kind of neural level or brain circuit level, but we can also still retain the importance of psychological factors, traumatic events. And I think it's also important to separate out, as you've done here with a question, what's the mechanism? How is the symptom happening versus why is it happening? Which often people don't do. So for this question, how is it happening? How is it that somebody, for example, gets a weak leg? Well, at a very simple level, their brain is disconnecting from their leg and that's what dissociation is. And you can explain that to patients at sort of brain circuit level. We've learned that there are disruptions probably in the circuits in our brain that relate to that sense of agency, the parts of our brain that tell us that our bodies belong to us. And people are particularly interested in an area called the temporary parietal junction. And at a higher broader level, people are particularly interested in the idea that FND is a disorder that you would expect to happen based on our understanding of the brain as a predictive organ. So if the brain spends its time predicting things, maybe in FND what's gone wrong is this is very strong prediction that the leg is weak or that there's a tremor or that a seizure's about to happen that overrides sensory input telling our brain otherwise. Dr. Gabriela Gilmour: And I guess to follow into that, you mentioned what is going on. So now can you talk a little bit about why somebody might develop FND or the etiology of FND? Dr. Jon Stone: I think this helps clinically as well as neurologists, because we can talk about mechanism as we would, for example, with MS as inflammation, but why is there inflammation? So okay, the brain's gone wrong, but why has it gone wrong? And there we need a much more complex view of multiple range of risk factors, predisposing, precipitating, and perpetuating that we know are associated with FND, but vary a lot from person to person. So no one person's the same. If you've had traumatic experiences in the past, that will make you more prone to dissociation. If you've had other functional disorders, if you have almost certainly some forms of genetics make people predisposed. And then as we said in the last episode, having another neurological condition, so having migraine aura, a physical injury, an infective illness, these are powerful reasons to trigger neurological symptoms. And it's not so much why they happen. It's more why do they get there and get stuck? We all probably have transient functional symptoms actually, but why they get stuck in people with FND for various reasons to do with the way their brains work or their past experiences, or sometimes what happens to them in medical systems. So developing a very open idea about why someone might have FND really helps you, I think, explain that back to patients and produce individual sort of formulations of the problem. Dr. Gabriela Gilmour: Yeah. And I often say to my patients, "I don't know exactly why you, why today have this." And that's true in medicine in general. We actually often don't know why anybody develops any medical condition with a few exceptions, but we know about risk factors really. Dr. Jon Stone: Absolutely. It's one of the reasons I hate the term medically unexplained. Actually, I think FND is perhaps more explained in some ways than some of the other conditions like multiple sclerosis and ALS that we actually deal with where we really don't know why they happen. Dr. Gabriela Gilmour: Well, we will be back for more Neurology Minute episodes to continue our discussion on FND. Thanks for listening. /episode/index/show/neurologyminute/id/39433410

Highlights From the 2025 World Stroke Congress - Part 2 12/16/2025

Highlights From the 2025 World Stroke Congress - Part 2 In part two of this two-part series on this year's World Stroke Congress, Dr. Andy Southerland and Dr. Seemant Chaturvedi discuss the ATLAS meta-analysis. Learn more on the website. Show transcript: Dr. Andy Southerland: Hello everyone and welcome to this week's Neurology Minute. For this series, I've been speaking again with my friend and colleague, Seemant Chaturvedi, who is the director of the stroke program at the University of Maryland. And as always, Seemant is sharing hot off the presses results of presentations from this year's World Stroke Congress that was held in Barcelona, Spain in October. And for this Neurology Minute, he is going to be sharing with us the presentation of the ATLAS meta-analysis, a systematic review which looked at pulled data from multiple clinical trials and patients presenting with large vessel occlusions and large ischemic cores, looking at folks randomized between endovascular therapy and best medical management. So Seemant, what were the results of the ATLAS meta-analysis? Dr. Seemant Chaturvedi: So this was a meta-analysis of six clinical trials, which looked at patients with large core infarcts, and they evaluated the results in patients who were treated with endovascular therapy or medical therapy, and it included over 1,800 patients. The primary outcome was the shift analysis on the 90-day modified Rankin Scale, and this was favorable for a thrombectomy with an adjusted odds ratio of 1.63. In terms of the specific outcomes for modified Rankin of zero to two, this was seen in 20% with thrombectomy, 7.5% with medical therapy, for modified Rankin of zero to three, 37% with thrombectomy, and 20% with medical therapy. One important observation was that the mortality was lower with thrombectomy, 31% compared to 37%. Also, two other points worth mentioning, the cerebral hemorrhage rate was increased with thrombectomy compared to medical therapy 5.5 to 2.7%, and then we frequently wondered how big of an infarct will no longer benefit from thrombectomy. And so here, Dr. Sarraj presented the results and showed that there seemed to be some benefit up to 149 mLs and no benefit in 150 mLs or above. And so I think this gives us a lot of useful information in terms of material we can bring back to our emergency rooms for discussion with our interventional teams about who to treat, who not to treat, and about what are the realistic expectations. And so we look forward to the full publication. Dr. Andy Southerland: Well, thank you, Seemant, and it's nice to see that this full pooled analysis of these randomized clinical trials not only supports the finding of most of the individual trials, but also enhances it through increased sample size and data across trials. So as you point out, we'll look forward to the peer reviewed publication, but glad to be presented with these new data. And once again, thank you for joining us for this week's Neurology Minute, sharing your observations from the World Stroke Congress in Barcelona, Spain in October.

Targeting Self-Described Knowledge Gaps to Improve FND Education among Clinicians - Part 2 12/15/2025

Targeting Self-Described Knowledge Gaps to Improve FND Education among Clinicians - Part 2 In part two of this series, Dr. Jeff Ratliff and Dr. Dara Albert discuss what advice they have for people who care for patients with FND. Show citation: Miller R, Lidstone S, Perez DL, Albert DVF. Education Research: Targeting Self-Described Knowledge Gaps to Improve Functional Neurologic Disorder Education Among Clinicians. Neurol Educ. 2025;4(3):e200239. Published 2025 Sep 5. doi: Show transcript: Dr. Jeff Ratliff: Hi, this is Jeff Ratliff with Neurology Minute. I'm back with Dara Albert for the second neurology minute episode following our podcast episode about her paper published in Neurology® Education titled Education Research Targeting Self-Described Knowledge Gaps to Improve Functional Neurologic Disorder Education among Clinicians. Dara, what advice do you have for people who take care of patients with FND now that you've learned about the types of knowledge gaps and misunderstandings that exist in the healthcare community about FND? Dr. Dara Albert: I think it's really important that folks recognize that FND is a real disorder, that patients are really suffering with symptoms. It's not fake, it's not feigned, it's not malingering, and that these symptoms are very real and distressing to the patients who experience them. And so that's really important for folks taking care of these patients to first and foremost to recognize. And then it's really important that we recognize that there's been an explosion in our understanding. There's been a wealth of new knowledge that has been generated about this diagnosis over the last 10 to 20 years. And so it's really important for folks that are less knowledgeable about this topic to read up and learn what we've been learning about FND and be able to approach these patients in a whole different way. Dr. Jeff Ratliff: Dara, thank you. Check out the full podcast discussion that we had about this topic to hear more details and read the paper. It's in the September, 2025 issue of Neurology® Education. This has been the Neurology Minute Daily Briefing. Thanks for listening. /episode/index/show/neurologyminute/id/39412590
