Explaining Parkinson's symptoms and pathology

Ray Dorsey joins me to discuss The Parkinson's Plan, his new book about fighting and hopefully ending the disease. Ray and his co-author Michael S. Okun show that Parkinson's is primarily caused by human-made chemicals, chemicals we can stop using. As with climate change or ultraprocessed foods, we've made an environment that's sickening us. Now it's time to make a new, healthier world.
