Illustration showing affected parts of the brain Cause of supranuclear palsy

Progressive supranuclear palsy, also called Steele-Richardson-Olszewski syndrome, is a brain disorder that causes serious problems with walking, balance and eye movements. Progressive supranuclear palsy results from deterioration of cells in areas of your brain that control movement.

Progressive supranuclear palsy is a rare disorder that slowly worsens over time. Although it's not life-threatening itself, progressive supranuclear palsy can lead to life-threatening complications, such as pneumonia and swallowing problems.

Because there's no cure for progressive supranuclear palsy, treatment focuses on managing and improving the related signs and symptoms.
