Parkinson's disease is more common in those who are exposed to pesticides and have suffered from head injuries, say European researchers. Furthermore, as exposure to brain injuries increases, the chances of illness also increase. Dr. Finlay Dick, from the Department of Environmental and Occupational Medicine at Aberdeen University Medical School, says that "those who were heavily exposed to pesticides had a 41 percent increased risk of developing Parkinson's disease, and those with lower exposure had a 13 percent increased risk."
