Is Parkinson’s A Preventable Disease? A Conversation w Dr. Ray Dorsey & Steve Brandenburg On Paraquat & Parkinson’s

from Why Should I Trust You? · host Brinda Adhikari, Tom Johnson, Maggie Bartlett, Dr. Mark Abdelmalek

Parkinson’s Disease is rising worldwide. It is the fastest-growing neurological disease in the world and is being called a “slow-motion epidemic.” And there is no cure. So what’s driving the increase? There are several culprits, including a body of research associating exposure to the farm herbicide Paraquat. Paraquat is banned in 70 countries. At the same time, in America, the EPA and other major reviews say the evidence still falls short of proving a direct causal link.We speak with one of the nation’s leading Parkinson’s researchers, Dr. Ray Dorsey, along with a man living with Parkinson’s after decades during which he says he was exposed to Paraquat.But this story goes beyond one chemical or one disease. It’s about how we should make decisions regarding health amidst conflicting perspectives over science, data, warning signs, and painful lived experiences.Hosts:Brinda AdhikariTom JohnsonMaggie BartlettDr. Mark AbdelmalekGuests:Steve Brandenburg, worked for 30 years as a producer on a video team in the agricultural industry.
