Agent Orange Tied to Parkinson’s in Vietnam Vets

(Beyond Pesticides, July 30, 2009) A new report from the Institute of Medicine (IOM) and sponsored by the U.S. Department of Veterans Affairs finds suggestive but limited evidence that exposure to Agent Orange and other herbicides used during the Vietnam War is associated with an increased chance of developing ischemic heart disease and Parkinson’s disease in Vietnam veterans. The report is the latest in a congressionally mandated series by IOM that every two years reviews the evidence about the health effects of these herbicides and a type of dioxin – TCDD – that contaminated some of the defoliants. A finding of “limited or suggestive evidence of an association” means that the evidence indicates there could be a link between exposure to a chemical and increased risk for a particular health effect, though conflicting results from studies, problems with how the studies were conducted, or other confounding factors limit the certainty of the evidence. Until now, the cumulative evidence had been inadequate to draw conclusions about whether these two conditions may be associated with veterans’ exposures to herbicides or TCDD. Ischemic heart disease – a condition characterized by reduced blood supply to the heart, which can lead to heart attack and […]
