Overview

Progressive supranuclear palsy is an uncommon brain disorder that causes serious problems with walking, balance and eye movements, and later with swallowing. The disorder results from deterioration of cells in areas of your brain that control body movement, coordination, thinking and other important functions. Progressive supranuclear palsy is also called Steele-Richardson-Olszewski syndrome.

Progressive supranuclear palsy worsens over time and can lead to life-threatening complications, such as pneumonia and swallowing problems. There's no cure for progressive supranuclear palsy, so treatment focuses on managing the signs and symptoms.
