Fans of the purity more likely to suffer from dementia

Lack of microbes in the life of modern man, or so-called hygiene hypothesis may be the cause of Alzheimer's surge. That is the conclusion drawn by researchers from the University of Cambridge.

Alzheimer's disease

Until recently, the hygiene hypothesis was considered only in the context of children's health weakened. It was believed that the smaller mom let kids run around in the puddles and messing around in the mud, the cleaner of the room, the weaker the immune system because it is not "trained" in the fight against all sorts of bacteria. In the poorest countries, the incidence of childhood allergies are much lower than in developed countries, and immunity in children is many times stronger.

Now, however, the Oxford scientists decided to test is not whether the theory explaining the outbreak of cases Alzheimer   in developed countries. They examined data on the incidence of dementia in 192 countries. It was found that in poor countries like Cambodia or Kenya,   Alzheimer's disease   It found 43% less than in rich countries. Of course, at the same time it takes into account the life expectancy of the population.

Developed countries are different from the poor by the fact that all their citizens have permanent and free access to clean drinking water. In addition, a significantly higher percentage of urbanized population - those who constantly live in cities with a higher level of care than the countryside.

"Hygiene hypothesis, implying a connection between a clean environment and a higher risk of allergies and autoimmune diseases, has long been known - said study author Dr. Molly Fox. - We believe that the list of diseases associated with this theory, it is necessary to include and illness Alzheimer's. This will help in forecasting the growth of the global incidence of dementia in developing countries. " (READ MORE)
