Parkinson's disease is most commonly caused by the death of dopamine-producing cells in the substantia nigra, a region of the brain that plays a role in movement control.
Dopamine is important for movement because it helps to control muscle movement. When there is not enough dopamine in the brain, people may have problems with movement and coordination. Some other causes of Parkinson's disease include head injury, environmental toxins, and genetics.
