Case Discussion
Progressive supranuclear palsy (PSP), also known as the Steele-Richardson-Olszewski syndrome, is a neurodegenerative disease with no efficacious treatment.
Progressive supranuclear palsy typically becomes clinically apparent in the 6th decade of life, and progresses to death usually within a decade (2-17 years from diagnosis).
