Knowledge of several languages slows down Alzheimer's disease

According to researchers from Concordia University, USA, the presence in the body of knowledge of two or more foreign languages can significantly slow the development of Alzheimer's disease.

Such conclusions of scientists are based on the analysis of data obtained with the participation of 94 volunteers with a history of diagnosed the presence of disease, or present a slight cognitive impairment. The results of this work were published in The Daily Mail.

The participants were divided into two groups, one of which was attended by only monolingual people, and another multilingual. Scientists have measured the density and thickness of the cerebral cortex of patients in different parts of the brain, including those responsible for memory and language functions.

In the result, it was found greater amount of gray matter in the studied brain structures of people who are fluent in two or more languages than the monolingual subjects. Scientists explain the phenomenon of switching between languages, forming more neural connections in areas associated with the performance of, and preservation of gray matter in affected areas.
