What causes Parkinson's disease?

In brief: Causes of Parkinson's disease

In Parkinson's disease, production of a substance called dopamine in the brain is reduced.
Dopamine is a neurotransmitter involved in passing messages within the brain and from the brain to the muscles. The part of the brain affected is called the substantia nigra, which co-ordinates muscle movement.


No one knows exactly what causes Parkinson's disease, but studies with identical twins suggest that genetic factors play a part. Also, some patients with generalised brain disease get Parkinson-like symptoms, which suggests that earlier damage to the brain might have a role in causing the disease. Parkinson's disease is not contagious.
