I just finished interviewing Behnam Sabayan and Natalia Rost for this week's Neurology® Podcast. For today's Neurology Minute, I'm hoping you can tell us the main points of your paper, An Ounce of Prevention, the Growing Need for Preventative Neurologist. Dr. Behnam Sabayan: We are living in a very exciting time for the field of neurology where we are not just getting very good at diagnosis and treatment of neurological condition, but also we are stepping one step back, and that means that we will find the root causes of neurological conditions. We would act as preventive specialists and we would decrease the burden of neurological conditions, not just at the individual level, but also at the population level. And this paper calls for thinking about playing roles at different levels and stages from our offices and our rounds all the way to the community to be brain health advocates and helping other fields and disciplines to reduce the burden of neurological conditions. Dr. Greg Cooper: Well, thank you for that summary and for all of your work on this topic. Please check out this week's podcast to hear the full interview or read the full article published in Neurology®, An Ounce of Prevention: The Growing Need for Preventative Neurologists. Thank you.

In the final episode of this seven-part series, Dr. Jon Stone and Dr. Gabriela Gilmour wrap up the conversation discussing future directions.

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.

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:10.1016/B978-0-12-801772-2.00043-6 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. Thanks for listening.

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.

Dr. Zohaib Siddiqi talks with Dr. Catarina Bernardes about a case involving a 35-year-old woman presenting with personality changes and gait impairment.

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.
