    • Parkinson’s May Begin in Gut and Spread to the Brain Via the Vagus Nerve

      Its amazing how many things are being blamed on the gut these days, we need to look after our guts!

      A major epidemiological registry-based study from Aarhus University and Aarhus University Hospital indicates that Parkinson’s disease begins in the gastrointestinal tract; the study is the largest in the field so far.


      The chronic neurodegenerative Parkinson’s disease affects an increasing number of people. However, scientists still do not know why some people develop Parkinson’s disease. Now researchers from Aarhus University and Aarhus University Hospital have taken an important step towards a better understanding of the disease.

      New research indicates that Parkinson’s disease may begin in the gastrointestinal tract and spread through the vagus nerve to the brain.

      “We have conducted a registry study of almost 15,000 patients who have had the vagus nerve in their stomach severed. Between approximately 1970-1995 this procedure was a very common method of ulcer treatment. If it really is correct that Parkinson’s starts in the gut and spreads through the vagus nerve, then these vagotomy patients should naturally be protected against developing Parkinson’s disease,” explains postdoc at Aarhus University Elisabeth Svensson on the hypothesis behind the study.

      A hypothesis that turned out to be correct:
