What Is Progressive Supranuclear Palsy?
Progressive supranuclear palsy (PSP) is a rare brain disorder. It causes serious and permanent problems with control of gait (walking) and balance.
The most obvious sign of the disease is when you can't aim your eyes properly. This occurs because of lesions in the area of the brain that coordinates eye movements. Some patients describe this effect as a blurring.
