Gut microbiome changes may signal Parkinson's disease risk

Analysis of microbes in the gut can reveal whether a person faces an elevated risk of Parkinson's disease, before they have developed any symptoms, suggests a new study led by University College London (UCL) researchers. The scientists found that people with Parkinson's disease have a distinctive makeup of gut microbes, as do healthy individuals who are genetically at risk of Parkinson's disease, they report in the new Nature Medicine study.
