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.

Posterior reversible encephalopathy syndrome: not always posterior, or reversible, or with associated encephalopathy. These and other clinical and neuroimaging factoids are reviewed in this week's edition of BrainWaves where we discuss the various--and often disparate--features of PRES. BrainWaves podcasts and online content are intended for medical education only and should not be used to guide medical decision-making in routine clinical practice. Any cases discussed in this episode are fictional and do not contain any patient health-identifying information. The content in this episode was vetted and approved by Amy Pruitt.
