There’s an interesting essay in today’s New York Times about the environment and Parkinson’s. Excerpt: “Some 90,000 cases of Parkinson’s are now diagnosed each year in the United States, about one every six minutes on average. It is the world’s fastest-growing neurodegenerative disease, causing tremors, stiffness and balance problems. It is also the 13th-leading cause of death in the United States. One factor in its increase may be the way we have come to live, for there’s growing evidence linking it to a range of pesticides and industrial chemicals, including paraquat and substances used in dry cleaning.”
