US scientists looked at links between exposure to air pollution and Parkinson's disease in 346 US patients with the condition and 4,813 people who did not have Parkinson's. They found that being exposed to higher levels of air pollution in the form of particulate matter with a diameter of 2.5 μm or less (PM2.5) and nitrogen dioxide (NO2) increased the risk of developing Parkinson's. And those exposed to the highest pollution levels were the most likely to develop Parkinson's accompanied by involuntary movements or tremors and rigidity - the loss of the ability to move freely. The findings suggest reducing air pollution may reduce the risk of Parkinson's, and the risk of people developing problems with movement if they do get the condition, the authors conclude.

Air Pollution and Parkinson Disease in a Population-Based Study
About The Study: The findings of this study suggest that a reduction in air pollution may help reduce Parkinson disease risk, modifying the Parkinson disease phenotype and the risk of dyskinesia in patients with Parkinson disease.
