Progressive supranuclear palsy is a neurodegenerative disorder that gradually destroys cells in many areas of the brain, leading to serious and permanent neurologic symptoms. People often confuse it with Parkinson's disease because the symptoms may be similar.
Signs and symptoms of progressive supranuclear palsy include inability to walk, falling spells, changes in personality, forgetfulness, dizziness, stiffness, and problems with the control of gait and balance. There is damage in the area of the brain that coordinates eye movements, so most people have trouble controlling eye movements and maintaining eye contact during a conversation. Other symptoms can include dementia, depression, and loss of interest in socializing with friends and family.
