Today on the show, a new understanding of Parkinson's disease. Parkinson's disease is one of the most common neurodegenerative disorders — right after Alzheimer's disease. It's familiar to many as a movement disorder: people with the disease develop difficulties with voluntary control of their bodies. But the real story is much more complicated.This week, we speak with Kathleen Poston, a Stanford neurologist who is at the forefront of efforts to redefine Parkinson's disease and related disorders based on their underlying biology — not just their symptoms. As Poston says: "The biology is the disease." Join us to learn about exciting advances in our ability to detect the brain pathology driving these disorders much earlier, even before symptoms arise, and how this is opening doors for early intervention and — hopefully — prevention.Learn MorePoston Lab at Stanford MedicineLewy Body Dementia Research Center of Excellence at StanfordUnderstanding Parkinson's Disease: Stanford's Dr. Kathleen Poston on latest advances (CBS News Bay Area - Video)A biological definition of neuronal α-synuclein disease: towards an integrated staging system for research (The Lancet - Neurology, 2024)International Working Group Proposes New Framework for Defining Parkinson Disease Based on Biology, Not Symptoms (Neurology Live article)Episode CreditsThis episode was produced by Michael Osborne at 14th Street Studios, with production assistance by Morgan Honaker.
