Early Parkinson’s warning signs may be hiding in the gut, study finds

A study led by University College London found that specific gut bacteria can predict Parkinson’s disease risk years before symptoms appear. The research, involving 271 Parkinson’s patients and 43 carriers of the GBA1 genetic variant, revealed distinct microbial patterns linked to the disease, with non-symptomatic carriers showing intermediate changes. Dietary diversity was associated with lower Parkinson’s risk.
