Progressive supranuclear palsy

neurodegenerative disease characterized by supranuclear gaze palsy, postural instability, progressive rigidity, and mild dementia

Progressive supranuclear palsy (PSP; or the Steele-Richardson-Olszewski syndrome, after the doctors who described it in 1963) is a degenerative disease involving the deterioration and death of specific volumes of the brain.[1][2] Males and females are affected the same equally and there is no racial, geographical or occupational predilection. Approximately 6 people per 100,000 population have PSP. It has been described as a tauopathy.[3]
