Abstract

A progressive supranuclear palsy (PSP)-like syndrome due to vascular or anoxic brain insult is rare. We describe a 65-year-old man with a progressive PSP-like phenotype associated with hypoxic–ischemic bilateral striopallidal lesions, secondary to rupture of and subsequent surgery for a thoracic aortic aneurysm. After early extrapyramidal features, 10 months later he started to fall, and developed levator inhibition. A supranuclear gaze palsy for downgaze was documented 5.5 years after the insult. © 2005 Movement Disorder Society
