Gut microbiome can reveal risk of Parkinson’s, scientists say

Study shows signature changes more pronounced in people with genetic risk, raising hopes for new therapies

Changes to microbes that live in the gut can identify people at greater risk of Parkinson’s disease long before symptoms develop, according to work that also raises hopes for new therapies.

Researchers discovered signature changes in the gut microbiome that are more pronounced in people with a genetic risk for Parkinson’s and even more stark in those diagnosed with the disease.
