The Gut-Brain Connection in Parkinson’s: Surprising Clues from the Microbiome

In this episode of CareLab, we’re joined by Dr. Lawrence Schiller, renowned gastroenterologist and educator, to explore the fascinating and emerging connection between gut health and Parkinson’s disease. From constipation and swallowing challenges to the groundbreaking idea that Parkinson’s may begin in the gut's nervous system, this conversation will change the way you think about digestive health and neurodegenerative disease.

We break down the gut-brain connection in a way that’s clear and practical—discussing early digestive symptoms, the role of the enteric nervous system, and how communication between doctors, therapists, and patients can make all the difference. You’ll also learn what the science says (and doesn’t say) about probiotics, what to do if your symptoms are dismissed, and why treating Parkinson’s as a full-body condition—not just a brain disease—matters.
