What is progressive supranuclear palsy?

Progressive supranuclear palsy (PSP) is a rare disorder. Like Parkinson's disease, it causes problems with balance when a person walks or stands. Rigid and stiff muscles, especially in the neck and spine, make body movement hard. The symptom that most makes PSP different from Parkinson's disease is a problem with eye movement. This occurs along with the body movement problems.

Problems with speech and swallowing are more common and become worse in PSP than in Parkinson's disease. Problems with thinking and changes in the way a person acts and feels are also more common. PSP progresses more quickly than Parkinson's. It often leads to disability within 5 years.

While there is currently no cure for PSP, some symptoms may be controlled with medicines.

Working with physical and speech therapists and a dietitian can also be helpful.
