Can Parkinson's disease be prevented?

Scientists understand that the symptoms of Parkinson's disease occur because there isn't enough dopamine present in the brain. But they don't understand why the shortage of dopamine occurs, meaning they don't understand what causes Parkinson's. Without knowing the cause, there is no way to prevent the disease.

Parkinson’s disease cannot specifically be prevented but there are several environmental factors that influence the chance of being diagnosed with Parkinson’s disease. Factors that may protect against the development of Parkinson’s disease include cigarette smoking and caffeine consumption. Neither are medically recommended as a specific measure to protect against Parkinson’s disease because of the well-recognized consequences associated with both. Risk factors for developing disease include having a rural residence (likely related to higher risk of pesticide exposure), pesticide and herbicide exposure and use of well water.
