Gut link to Parkinson's sparks talk of probiotic treatment strategy

A U.K.-based research team showed that in roundworm models of Parkinson's disease, probiotic Bacillus subtilis lessened the toxic buildup of alpha-synuclein in the brain—a major culprit in the disorder. That relieved tremors, movement difficulties and other motor symptoms, bolstering previous research showing a link between Parkinson's disease and the gut microbiome, the scientists believe.
