Parkinson’s Disease | Symptoms

What are the symptoms of Parkinson's disease?

People who have Parkinson's disease experience tremors or shaking as a result of the damage to their nerve cells. Tremors caused by Parkinson's get worse when the person is at rest and better when the person moves. The tremor may affect one side of the body more than the other, and can affect the lower jaw, arms and legs. Handwriting may also look "shaky" and smaller than usual. Other symptoms of Parkinson's disease include nightmares, depression, extra saliva, difficulty walking or buttoning clothes, or cutting food.
