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. Siegler. Music courtesy of Chris Haugen, Kevin McLeod, and Meydan. The opening theme was composed by Jimothy Dalton. Sound effects by Mike Koenig and Daniel Simion.

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. Whether you lost a job, a loved one, or an invaluable life experience, I think we can all say BRING ON 2021! So let's welcome the new year with positive mental attitude, a bit more luck, and an unquenchable thirst for knowledge. Produced by James E. Siegler.

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. Produced by James E. Siegler and Monisha Kumar. Music courtesy of Rui, Swelling, Unheard Music Concepts, Jahzzar, Ian Southerland, and TRG Banks. The opening theme was composed by Jimothy Dalton.

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. Today's program is a re-run from 2017, featuring Dr. Brian Hanrahan, and has been remastered and updated with some recent additions in light of the coronavirus pandemic. Produced by James E. Siegler. Music courtesy of Andrew Sacco, Ars Sonor, Yan Terrien, and Unheard Music Concepts. The opening theme was composed by Jimothy Dalton.

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. And you have probably heard of the Evan’s index—the relative proportion of the lateral ventricles in reference to the inner table of the skull. But you might not have heard of high-convexity tight sulci. Now you have. Produced by James E. Siegler. Music courtesy of Jason Shaw, Javolenus, and Lee Rosevere, under a Creative Commons License.

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.

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 of ALS when all life-sustaining measures are desired. REFERENCES Patterson JR and Grabois M.

Webster defines ‘idiopathic’ as “arising spontaneously or from an obscure or unknown cause”. By definition, this means idiopathic intracranial hypertension (IIH) has no proximate cause. But that’s not exactly true. This week on the podcast, we explore the recent evidence behind the theory that transverse sinus stenosis may contribute to this condition.

On rounds, I sometimes joke that the two most important organs in the body are the right and left hemisphere. Only one of many, terrible, dad jokes my poor residents and students have to endure. But what happens when one organ fails, or you have to remove it? This week on BrainWaves, we’ll review a unique neurologic condition where such incredible hemispheric dysfunction can only be treated by surgically removing half of the brain. And OMG, a show about pediatrics! ** IF YOU’RE TAKING YOUR NEUROLOGY BOARDS THIS SUMMER, CHECK OUT THE PENN NEUROLOGY BOARD REVIEW COURSE AT https://upenn.cloud-cme.com/default.aspx?P=5&EID=65373.

Lewy Body Dementia may be the second most common neuropathologic cause of dementia behind Alzheimer disease, but it remains largely a clinical diagnosis with limited treatment options. This week on BrainWaves, Dr. Amy Colcher (Cooper University Hospital) reviews the diagnostic criteria and management strategies for patients and their caregivers who suffer from this condition.

It’s 2020, and for the first time in its 72-year history, the American Academy of Neurology has cancelled its annual meeting because of the COVID-19 pandemic. But that does not mean we (BrainWaves producers, not the AAN) can’t provide a few major updates to advances in neurology and neurotherapeutics! This week on the program, Jim Siegler is joined by Dr. Sammita Satyanarayan (Stanford) on a whirlwind tour of some of the latest advances in neurology from this past year. Enjoy! ** IF YOU’RE TAKING YOUR NEUROLOGY BOARDS THIS SUMMER, CHECK OUT THE PENN NEUROLOGY BOARD REVIEW COURSE AT https://upenn.cloud-cme.com/default.aspx?P=5&EID=65373.
