Parkinson's Link to Gut Bacteria Suggests Unexpected, Simple Treatment


Researchers have suspected for some time that the link between our gut and brain plays a role in the development of Parkinson's disease.

"Supplementation of riboflavin and/or biotin is likely to be beneficial in a subset of Parkinson's disease patients, in which gut dysbiosis plays pivotal roles," Nagoya University medical researcher Hiroshi Nishiwaki and colleagues write in their published paper. Analyzing fecal samples from 94 patients with Parkinson's disease and 73 relatively healthy controls in Japan, Nishiwaki and team compared their results with data from China, Taiwan, Germany, and the US. Nishiwaki and colleagues then showed the lack of B vitamins was linked to a decrease in short-chain fatty acids(SCFAs) and polyamines: molecules that help create a healthy mucus layer in the intestines.
