BrainWaves: A Neurology Podcast

Education


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.
