Maintaining more Hygiene increases Risk for Alzheimer's Disease

According to a new research report, too much cleanliness may increase the risk for developing Alzheimer’s disease. For the healthy growth of germs (normally considered to be bacteria) normally requires a hygienic atmosphere. Dr. Molly Fox and her co-researchers from the University of Cambridge identified that extreme hygienic atmosphere pushes a negative impact on the immune system, further increases the risk for Alzheimer’s disease (Check the Video below, what Dr. Molly Fox has to say). This research was published in the journal Evolution.

Different kinds of Bacteria, Viruses and other microorganisms, stimulate the body’s immune system to develop, thus people living in wealthy and industrialized country with better sanitation have greater risks for the brain disorder.

Researchers reached to this conclusion after assessment of prevalence of Alzheimer’s disease in 192 countries, while comparing the rates to factors like age, birth rate and life expectancy.

Survey Results:
  • ·         Alzheimer’s  was more prevalent in countries that have improved sanitation facilities (like clean drinking water)
  • ·         UK and France has 9% higher rate than Kenya and Combodia.
  • ·         Countries with lower rates of infectious diseases like Switzerland and Iceland has 12% higher rate than China and Ghana.
  • ·         UK and Australia, which are well urbanized countries have 10% higher rates than Nepal and Bangladesh.

“Hygene hypothesis” which led researchers to prove with the solid evidence – over sanitation at childhood may weaken the immune system, leading the increase of risks. The hypothesis also suggests that the relationship between cleaner environment and risks for allergies and autoimmune diseases is well established.
