How East St. Louis became a battleground against an international chemical giant

Parkinson’s disease is a chronic, progressive disorder with no cure, and its rate of incidence in the Midwest is one of the highest in the country. We explore why — including new research that shows a strong link between exposure to a widely used herbicide and the development of the disease. Journalist Mike Fitzgerald shares how East St. Louis became a battleground against the chemical giant that produces the herbicide and how the Trump administration’s cuts to biomedical funding could have big repercussions for people focused on a cure. We also hear from two St. Louis residents who live with the condition.
