What Is Parkinson’s Disease?
Parkinson’s disease, or PD, is a neurodegenerative disorder. Parkinson’s disease is a progressive nervous system disorder that affects your movement. Symptoms start gradually, sometimes beginning with a barely noticeable tremor in just one hand. The disorder also commonly causes stiffness or slowing of movement. Less than one percent of people get Parkinson’s. It is more common in men than women.
