MedLink Neurology Podcast is delighted to feature selected episodes from BrainWaves, courtesy of James E Siegler MD, its originator and host. BrainWaves is an academic audio podcast whose mission is to educate medical providers through clinical cases and topical reviews in neurology, medicine, and the humanities, and episodes originally aired from 2016 to 2021.

We've abused the term "idiopathic." Not all clinical conditions have to have an unclear cause. More and more, we are finding out the answers. This week, using transverse myelitis as an example, Dr. Clyde Markowitz shares his experience in working up unknown etiologies of spinal cord inflammation.

Produced by James E Siegler. Music by Quantum Jazz, Rui, and Steve Combs. Voiceover by Erika Mejia. BrainWaves' podcasts and online content are intended for medical education only and should not be used for clinical decision-making.
