New Study Suggests Parkinson’s May Start In The Gut, Not The Brain

A recent study suggests that Parkinson’s disease might begin in the gut, not the brain. Research shows gastrointestinal symptoms like constipation can appear decades before motor symptoms, supporting the “gut-first” hypothesis. Misfolded proteins in the gut may travel to the brain via the vagus nerve. This discovery opens doors for early intervention and potential treatments to the gut-brain connection.
