Parkinson’s Disease | Causes & Risk Factors


What causes Parkinson's disease?

Doctors don't know exactly what causes Parkinson's disease. In a small number of people, genetics seem to play a role. These people have either inherited the genes for Parkinson’s disease from a family member, or have a gene mutation. Environmental factors may also play a role. For example, long-term exposure to certain toxins, such as pesticides, may increase the risk of Parkinson’s disease, but the risk is small.
