With Parkinson disease, the brain cells that make dopamine slowly die. Without dopamine, the cells that control movement cannot send messages to the muscles. This makes it hard to control the muscles. Slowly, over time, this damage gets worse. No one knows what causes these brain cells to waste away. Parkinson disease most often develops after age 50. It is one of the most common nervous system problems in older adults. The disease tends to affect men more than women, although women also develop the disease. Parkinson disease sometimes runs in families.
