People with Parkinson’s disease have significantly higher blood levels of a particular pesticide than healthy people or those with Alzheimer’s disease, researchers at UT Southwestern Medical Center have found.
In a study appearing in the July issue of Archives of Neurology, researchers found the pesticide beta-HCH (hexachlorocyclohexane) in 76 percent of people with Parkinson’s, compared with 40 percent of healthy controls and 30 percent of those with Alzheimer’s.
The finding might provide the basis for a beta-HCH blood test to identify individuals at risk for developing Parkinson’s disease. The results also point the way to more research on environmental causes of Parkinson’s. MORE>>>>>>>>>>>>
