Study Concludes that Pesticide Use Increases Risk of Parkinson's in Men

The Harvard study dovetails with another study published this month in the journal Movement Disorders. Researchers at the Mayo Clinic found that men with Parkinson's were 2.4 times more likely to have had exposure to pesticides than those who did not have Parkinson's. "This confirms what has been found in previous studies: that occupational or other exposure to herbicides, insecticides and other pesticides increases risk for Parkinson's," says Jim Maraganore, M.D., Mayo Clinic neurologist and study investigator.
