The symptoms of Parkinson’s disease vary from person to person as well as over time. The disorder affects physical movement and people with Parkinson's may experience fatigue, and changes in mood and patterns of sleep.

The most common symptoms are:

Other symptoms include:

  • loss of unconscious movements, such as blinking and smiling
