New Study Shows Links Between Parkinson’s and Gut Biomes

A new study shows that one of the major contributing factors to Parkinson’s disease and Lewy Body Dementia may begin in the human gastrointestinal tract.

New Atlas has a report on the study published in the journal Cell. The study shows that the development of Lewy Bodies – clumps of proteins that interfere with neurological activities – may begin in the abdomen.

Over the last couple of decades, some researchers have begun to find evidence suggesting Parkinson’s may originate in the gut. The idea is known as the Braak hypothesis, and it posits that the damaging Lewy bodies could initially form in the gut, before spreading to the brain and generating the physiological symptoms we commonly see in Parkinson’s disease.

Lots more research is needed, and you shouldn’t run out to buy a probiotic yet. But any evidence showing the origins of neurodegenerative disease is something to be highlighted. And a study showing that even basic nutritional supplements may stave off symptoms is cause for real, albeit guarded, celebration.
