For the first time, researchers have found a functional link between the bacteria in the gut and the onset of Parkinson’s disease, one of the world’s most common debilitating brain disorders.
A team of scientists from several institutions in the United States and Europe showed how changing the bacteria in the guts of mice affected the manifestation of Parkinson’s symptoms — even including bacteria taken from the guts of humans with the disease.
The findings suggest a new way of treating the disease: The best target for treatment may be the gut, rather than the brain. The researchers hope the new information can be used to develop “next generation” probiotics, more sophisticated than the sort of probiotics found on the shelves of health food stores today.
