According to a recent study by researchers at University of California, Los Angeles, people who have suffered a traumatic brain injury and lived in areas with exposure to pesticides may be three times more likely to develop Parkinson's disease. In UCLA's recent study, researchers compared a group of 357 people with Parkinson's to 754 people without the disease. All respondents lived in an agricultural area in central California. Using records of pesticide applications dating back to 1974, researchers tracked exposure to paraquats in the study. The research participants were also asked to report any head injuries suffered in their pasts that caused loss of consciousness longer than five minutes. The examination found that 42 of the 357 people with Parkinson's reported having had a traumatic brain injury compared to 50 of the 754 people without the disease. Moreover, those with Parkinson's were 36 percent more likely to report exposure to pesticides than those without the disease. Ultimately, the research suggests that while brain injuries and pesticides are individually associated with an increased risk of Parkinson's, the combination is associated with a greater threat of developing the disease.
