The field of neurocritical care and traumatic brain injury management is rapidly evolving. We are shifting from older (but not entirely outdated) monitoring techniques to novel diagnostic and therapeutic advances in critical care medicine. Managing intracranial pressure crises involves the careful tiptoeing of a line between maintaining brain circulation and yet reducing intracranial fluid volume. And many of our interventions rely on one simple mathematical construct: CPP = MAP - ICP [Cerebral perfusion pressure = Mean arterial pressure – Intracranial pressure] The importance of this formula cannot be understated. So we are spending 35 minutes today reviewing it, and discussing pearls and pitfalls of ICP monitoring and management. But believe me, it’s worth it. Produced by James E. Siegler and Jon Rosenberg.

What do hip weakness, headache, and neglect have in common? At minimum, they can all be approached with simple neurodiagnostic heuristics. But there's more to neurology and medicine than having an approach to "leg weakness" or an approach to "headache". You have to adapt to new information as it presents itself. You have to know when, and how, to pivot. Produced by James E. Siegler, Minal Patel, and Jesse Thon. Voiceovers by Taryn Hester and Terri Yeager.

As many as 1% of the world has epilepsy, but far more than will have a seizure in their lifetime. Not everyone needs a seizure medication, some people are even harmed by them. So who warrants treatment, and what do you start with. Consider today’s program an intro to AED decision making. For educational purposes only, of course.

To quote Donald Rumsfeld, “there are things we know we know…. we know there are some things we do not know... But there are also unknown unknowns—the ones we don't know we don't know…it is the latter category that tends to be the difficult ones.” In neurology, the agnosias are not that dissimilar from Rumsfeld’s 'unknown unknowns.' In this week’s program, we discuss the nosology and nomenclature for the agnosias, the localization, and the importance of recognizing one. Produced by James E. Siegler.

Almost 5 years ago, we published a show on chronic traumatic encephalopathy and its relationship to American football. But a lot has happened since 2016. New rules in the NFL. Emerging data on how the developing human brain of a child or adolescent is even more vulnerable to pathologic changes following mild head injury. And a heightened awareness of the disingenuous campaign against contact sports among one of the most outspoken whistleblowers in the medical field. This week on the program, we have remastered and updated the 2016 program. With some additional commentary on how parenthood may yield a new perspective on contact sports. Produced by James E.

Happy New Year, and good riddance 2020! Hopefully there is more that you will take away from the past 12 months other than your personal experience with the coronavirus pandemic.

I shouldn’t have to tell you that traumatic brain injury is a major cause of morbidity and mortality. I shouldn’t have to. But I will. And it is. In severe cases of head injury, there can be delayed and irreversible deterioration in the nervous system for which there is no treatment and the prognosis is grim. This week on the program, Dr. Monisha Kumar (University of Pennsylvania) discusses the worst of the worst of these scenarios, what to look out for, and expert recommendations on what to do when it happens.

COVID-19 is more than just a threat to your physical health. Even if you are never infected, you may not be free of it. In today's program, we take lessons from prior pandemics and consider the sociocultural effects of a global infectious disease. Be advised, this one is of the "sentimental" variety.

Halloween is one of the most exciting and festive holidays, but this year I imagine many of us are going to spend it indoors. To help pass the time, enjoy this seasonal special about the neurologic manifestations of zombie-ism.

As the second most common vascular malformation in the central nervous system, cerebral cavernomas are often incidental radiographic findings. Also incidental is Jim’s interest in mediocre sci-fi television shows, such as Netflix’s recent series, Away—which incidentally includes one character with a symptomatic cerebral cavernoma. This week on the podcast, Dr. Siegler discusses with Dr. Dena Little (Cooper University Hospital) the epidemiology, clinical course, and management (including counseling) of patients with this vascular malformation. Plus, a critical appraisal of Away’s medical consultant. 0_o Produced by James E. Siegler and Dena Little. Music courtesy of Ars Sonor, Andrew Sacco, Chris Zabriskie, and Purple Planet Music.

You know the triad for normal pressure hydrocephalus (NPH). Wet, wobbly, and wacky.

Myoclonus is the most etiologically non-specific motor manifestation of neurologic and systemic disease. It’s like slurred speech or altered mental status. But in the appropriate context, it can become a useful clue in your differential diagnosis.

A lot can happen in two years. You might have matched into residency, graduated from fellowship, had a kid... Or several phase II trials in low grade glioma research could have been published.

The locked-in syndrome is a rare clinical consequence following many types of neurologic injury. In general, the locked-in patient is fully paralyzed, with perhaps minimal function of the fingers, the eyes, or the mouth. What's more, the gross motor dysfunction is enormously disproportional to the cognitive function of the individual. The locked-in patient is conscious and completely aware of their surroundings. They can often hear, see, smell, and feel just as any other person would. But because of their profound physical disability, they have a very limited means of communicating even the simplest thoughts. "I feel hot." "My head hurts." "My cheek itches." It may surprise you that the patient's perspective of their condition is wholly different from how the healthcare provider or caregiver imagines it to be. This week on the program, Dr. Lauren Elman (Pennsylvania Medical Center ALS Multi-disiplinary Clinic) reviews this discrepancy. Dr. Elman also shares her experience  managing this inevitable consequence
