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.
PARKINSON DISEASE CAUSE. The cause of Parkinson disease is not known. Normally, certain nerve cells (neurons) in the brain make a chemical called dopamine, which helps to control movement. In people with PD, these neurons slowly degenerate and lose their ability to produce dopamine.owever, the tremor of PD usually does not affect the head. The majority of people with Parkinson disease will notice a tremor at some point in the disease, though some do not. The side of the body that is first affected by the tremor also tends to be more severely affected throughout the course of the disease.
