While Parkinson's might not be prevented if you are predisposed for it, you can take a few precautionary steps to lower your risk. Some of these steps are:

• Drinking caffeine: To some, this may seem a little counterproductive, but caffeine has a surprising effect on Parkinson's disease symptoms. A study in the Journal of Alzheimer's Disease observed that caffeine can aid Parkinson's patients in restoring their early symptoms, both motor and non-motor.
• Using anti-inflammatory drugs: Specifically NSAIDS. These drugs can help prevent Parkinson's symptoms from developing, at the very least, slow them down.
• Having enough vitamin D: Vitamin D deficiency is linked to many different diseases. Parkinson's disease just so happens to be one of them. Preventing this deficiency is key to reducing your risk for Parkinson's disease.
• Exercising: Yes, we mean it. Being active can help improve symptoms of muscle stiffness, mobility and even depression. It'll also reduce your risk substantially.
