Gut Microbiome Can Reveal Risk of Parkinson’s, Scientists Say

A study suggests changes in gut microbiome may help identify Parkinson’s risk years before symptoms, with stronger signatures in people with genetic susceptibility and in diagnosed patients. Researchers analyzing data from over 1,000 participants across multiple countries found distinct microbial patterns affecting hundreds of species, not explained by medication.

The findings, published in Nature Medicine, indicate potential for earlier detection and future preventive approaches, though causality remains unclear. Possible mechanisms involve gut inflammation and alpha-synuclein pathways linking gut and brain.

In addition, researchers observed links with diet patterns, underscoring the need for further study of modifiable risk factors. Read more from The Guardian here.
