Research has found a link between pesticide exposure and an increased risk of Parkinson's disease. Certain pesticides, including chlorpyrifos and paraquat, have been specifically identified as potential contributors to this risk, which may affect not only farmworkers but also nearby communities. The connection between pesticides and Parkinson's disease is being explored in various studies, with some investigations focusing on specific regions, such as Texas' Rio Grande Valley, and others examining the broader implications of pesticide use.
