Parkinson's disease (or, simply, Parkinson's or PD) is the most common form of parkinsonism, a group of motor system disorders. It is a slowly progressing, degenerative disease that is usually associated with the following symptoms, all of which result from the loss of dopamine-producing brain cells: Tremor or trembling of the arms, jaw, legs, and face.
When the dopamine-producing nerve cells die, symptoms such as tremor, slowness, stiffness, and balance problems begin to occur. The cause of Parkinson's is largely unknown, and the disease cannot be cured at this time. Treatments focus on reducing symptoms to enable a more active lifestyle.
