People who know two languages, thereby delaying development of Alzheimer's disease at a later date.
Scientists have conducted monitoring of 211 subjects who were suspected Alzheimer's disease, fixing, at what age they began to deteriorate cognitive abilities. 102 participants of the experiment were bilingual, while 109 said in one language only.
As it turned out, a bilingual mental capacity begins to deteriorate with an average delay of 4.3 years, and the symptoms of Alzheimer's disease manifested by 5,1 years later than a monolingual peers. In explanation of this phenomenon, researchers make such an assumption: the brain, probably stimulated by switching from one language on the other. The effect is most pronounced in people who daily use different languages, ie Sun while facing the choice of a word from its bilingual arsenal. Of course, brings great benefit and learning languages in school, as well as the following regular language practice.
But now the Canadian specialists trying to figure out is whether any changes in the brain using two or more languages. Preliminary results of this study hint at polyglossy can affect even the size of the brain.
Another Science Study, undertaken by the psychologist (USA), Judith Kroll, experimentally confirmed that the ownership of more than than one language keeps the brain fit and improves mental function. In particular, the researcher found that bilingual individuals are better than monolingual cope with the tasks of mental activity, such as removing irrelevant information and focus on important details. In addition, bilinguals better than others to prioritize and cope with multitasking. ( source )
