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

Are you interested in learning more about a historically disabling disorder for which we now have a spectrum of new therapies that, if used appropriately and promptly in the right clinical situation, promise to dramatically improve patient outcomes? If so, keep listening. My name's Dr Gordon Smith. Today I'll be talking with Dr Sara Mariotto about her article on neuromyelitis optica spectrum disorder or NMOSD, which she wrote with Dr Romain Marignier. This article appears in the April 2026 Continuum issue on multiple sclerosis. Dr Jones: This is Dr Lyell Jones, Editor-in-Chief of Continuum. Thank you for listening to Continuum Audio.

Dr Smith: This is Dr Gordon Smith. Today, I'm interviewing Dr Sara Mariotto about her article on neuromyelitis optica spectrum disorder or NMOSD, which she wrote with Dr Romain Marignier. This article appears in the April 2026 Continuum issue on multiple sclerosis. Sara, welcome to the podcast, and maybe you can start by introducing yourself to our audience. Dr Mariotto: Yes. Thanks, Gordon. I'm Sara Mariotto. I'm a neurologist, and I work at the Neurology Unit, University of Verona, where I do both clinical diagnosis and research into neuroimmunology---so, in particular, autoimmune encephalitis, NMOSD, and MOGAD. Dr Smith: Well, this is a super exciting area. Whenever I hear about NMOSD, I think of one specific patient I had, and I always think of her when I come across something like your article, which is really fantastic. So, before we dive into the details, I wonder if maybe you can just explain to our listeners who aren't up to speed on what NMOSD is, what the disorder is, and maybe why it's so important that all of our listeners learn how to recognize it quickly and get people started on therapy. Dr Mariotto: Yes, sure. So, neuromyelitis optica is an inflammatory autoimmune CNS disorder usually associated with aquaporin-4 antibodies, although there are a few cases, around 10%, who can be antibody-negative. And I think it's very much important to have in mind this disease and recognize it because it can be severe, as you pointed out; can present with very severe

Diabetic neuropathy is more than a disorder of numbness and pain in the feet. In this episode, Dr. Vera Fridman discusses diabetic neuropathy as a complex, multisystem condition, highlighting the importance of recognizing autonomic involvement, identifying high-risk patients early, and addressing factors that influence progression. Learn practical strategies for screening, prevention, symptom management, and recognizing when symptoms may suggest an alternative diagnosis.

In this clinic, Dr. Vera Fridman emphasizes that diabetic neuropathy is not simply a disease of the feet, revealing it instead as a complex neurologic syndrome with consequences that reach far beyond numbness and pain.
Neuropathy can present in many ways beyond the classic pattern of numbness and tingling.

But what about if it's not? Or what if the EMG and nerve conduction studies suggest something else? What if the patient is giving you extra clues about other symptoms where they feel ataxic or have systemic complications as well? All of those things may be part of a neuropathic picture. And today, we are so fortunate to talk to Dr. Seyedsadjadi about just this.

That's one of the reasons we like to study it and care for patients with neurologic problems. But to translate cognition into action, we need a functioning sensorimotor and autonomic peripheral nervous system. What do we do when those peripheral systems aren't working? Today, we're speaking with Dr. Noah Kolb, guest editor of our latest issue of Continuum on peripheral nerve and motor neuron disorders.
Sleep plays a critical role in brain development, learning, memory, and behavior throughout childhood and adolescence. In this episode, Dr. Kristin Seaborg discusses how sleep architecture changes across development, the impact of sleep disorders on attention, headaches, epilepsy, and neurodevelopmental conditions, and why neurologists should routinely assess sleep in pediatric patients. Learn practical approaches to recognizing sleep problems, including obstructive sleep apnea and insomnia, and how improving sleep can enhance neurologic and cognitive outcomes.

Dr Albin: Hello, this is Dr. Casey Albin. Today I'm interviewing Dr. Kristin Seaborg about her article on sleep in the developing brain. This article appears in the August 2026 Continuum issue on the neurology of sleep. Welcome to the podcast, Dr. Seaborg. Thank you so much for being here. I learned a lot from your article. Can you just briefly introduce yourself to the audience? Dr Seaborg: Sure. Thank you for having me. I'm thrilled to be here. My name is Kristin Seaborg. I'm a pediatric neurologist and sleep neurologist at the University of Wisconsin Medicine. I also run the pediatric sleep neurology clinic at UW Madison. Dr Albin: That is the perfect person to be writing this article. And every time I read an article about pediatric neurology, I am just so struck that like little tiny humans are not small adults, that they actually have a totally different neurobiology. They are in different stages of development. And this was really a topic that I was not familiar with, and probably for most of our listeners, they're not familiar with as well. And so, I thought we'd maybe just start with some of the basics. What is going on in terms of like pediatric sleep architecture, and how is that different than the adult architecture that we might be m- more familiar with? Dr Seaborg: Sure. So, a lot of us think that sleep is the thing we do that when, when we're not doing other stuff. But actually, it's completely the opposite. During sleep, our brain is learning and consolidating memory and cleansing what's happened during the day, and that's especially important during infancy and early childhood development, and as a child gets older. If we take infants for an example, fifty percent of their sleep is in a precursor of REM sleep, which we call active sleep, which is much, much more than adults, as opposed to adults have about thirty percent of their sleep in REM sleep.
