In this episode of Revolution Health Radio, Chris Kresser sits down with neurologist Dr. Ray Dorsey, author of The Parkinson’s Plan, to challenge the conventional view of Parkinson’s disease as primarily a consequence of aging and genetics. Dr. Dorsey makes the case that environmental exposures—including pesticides, industrial solvents, air pollution, and heavy metals—play a major role in the development and progression of Parkinson’s disease. Their conversation explores the epidemiological and biological evidence connecting these exposures to Parkinson’s, including dose-response relationships, geographic patterns, and laboratory research. They also offer practical strategies for reducing exposure through cleaner food, filtered water, improved air quality, and avoiding unnecessary pesticide exposure. The discussion concludes with a broader vision of shifting medicine from treating disease after it appears to identifying and addressing environmental causes before disease develops.
