A new study published by the medical journal Science Translational Medicine discovered that there could be a correlation between Parkinson’s disease and the Appendix. The research discovered that the people whose appendix were removed had less chances of getting a neurodegenerative disease. The Appendix, an organ whose function still unknown, it also proved to be a reservoir of the substance that kills brain cells. There is a link because in Parkinson’s disease, toxics proteins accumulate in the brain and kill nerves, especially those linked to movement. Although it may seem counterintuitive, there is growing evidence that the digestive system has a link to the disease. The analysis revealed that the risk of developing Parkinson’s disease was 20% lower in people who had had their appendix removed. However, the search for the origin of Parkinson’s still can’t answer why the disease appears in some people and not in others.
