Parkinson's disease - Symptoms and causes - Mayo Clinic
Causes. In Parkinson's disease, nerve cells in the brain called neurons slowly break down or die. Many Parkinson's disease symptoms are caused by a loss of neurons that produce a chemical messenger in the brain. This messenger is called dopamine. Decreased dopamine leads to irregular brain activity.
