Studies have found that some people with specific genetic mutations are more susceptible to environmental toxins, such as mercury.rnrnThe early in life exposure to these environmental toxins makes them more susceptible to Parkinson’s disease.rnrnMercury exposure also lowers the cell’s levels of Glutathione, Dopamine and NAD.rnrnThese cellular changes specifically target the portion of the midbrain that controls movement. The mercury sensitive patient then shows symptoms of Parkinson’s disease when they reach the age of about 60 years old.
