Parkinson's Disease 25 percent more likely if air pollution (likely lower Vitamin D)
Mississippi–Ohio River valley linked to higher risk of Parkinson’s disease
"In total, researchers identified 83,674 Medicare beneficiaries with incident Parkinson’s disease, with 434 new cases per 100,000 people in the highest exposure group, compared with 359 new cases per 100,000 people in the lowest-exposure group. The relative risk for Parkinson’s disease increased in the highest quartile of PM2.5 by 25%, compared with the lowest quartile after adjusting for factors such as age, smoking status, and health care usage (95% confidence interval, 20%–29%)."
