A. A. A. Parkinson's disease is caused by the progressive impairment or deterioration of neurons (nerve cells) in an area of the brain known as the substantia nigra. When functioning normally, these neurons produce a vital brain chemical known as dopamine.
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.
