What is Parkinson's disease?

Parkinson's disease causes problems in the nerve cells in the brain that control muscle movement. Nerve cells that make a chemical called dopamine normally send signals that help coordinate your movements. In people who have Parkinson's disease, these cells die or do not work properly. The disease's effects get worse over time.
