History of PSP 
Progressive Supranuclear Palsy (PSP for short) was first described and named by doctors in 1964. Before then people with the condition were thought to have Parkinson's disease. PSP is sometimes called 'Steele-Richardson-Olzewski Syndrome' after the doctors who first described the condition. Other terms sometimes used for PSP are 'Richardson's disease', PSP-parkinsonism' or (PSP-P) and 'purse akinesia with gait freezing'. Many people first heard of PSP when British actor and comedian Dudley Moore disclosed he had the condition in 1999.
