Better Hygiene Linked to Higher Rates of Alzheimer’s

The Huffington Post reports on a study in Evolution, Medicine and Public Health that has shown a connection between the hygiene of a country and the likelihood of the development of Alzheimer’s in individuals of that country. The study used “age-standardized data” and found that better hygiene was linked to higher rates of Alzheimer’s disease. Scientists suggest that better hygiene may mean that people are not exposed to bacteria, viruses, and other microorganisms and that this lack of exposure may compromise the immune system of an individual causing inflammation of the brain. The findings further the previously supported “hygiene-hypothesis,” which links better hygiene to a wide range of allergy and autoimmune diseases.
