Altered bacterial communities in the gut could be an indicator for Parkinson’s disease

By the time Parkinson’s disease manifests as the typical motor dysfunctions, portions of the brain have already been irreversibly destroyed. In search of an early portent of the disease, researchers may now have found one in the gut: they have shown that the bacterial community in the gut of Parkinson’s patients differs from that of healthy people even at a very early stage of the disease.
