At the moment, there are no drugs that can slow down the manifestation of the symptoms of this disease. However, scientists have been able to prove that language skills can significantly delay the manifestation of Alzheimer's disease.
Scientists have discovered that by the time the first symptoms of Alzheimer's disease appeared in people who speak fluently in two languages, there were twice as many injuries to the brain caused by this disease than those who speak only one language.
Scientists from St. Michael's Hospital in Toronto studied the computer tomography of patients with Alzheimer's Disease, who had the same level of education, social status, and similar cognitive skills (attention, memory, planning, and organization). Half of the participants in the study spoke fluently in two languages, the other half had only one language.
Despite the fact that in both groups of patients the symptoms of the disease were virtually identical, the scans made it possible to establish that in people with bilingualism, the atrophy of some parts of the brain caused by Alzheimer's disease was expressed twice as much as in others.
This can be explained by the fact that people who are fluent in at least one foreign language constantly use their brain and give it a large load, which ultimately affects the general condition and health. That is why many doctors advise elderly people to solve crossword puzzles, collect puzzles and other puzzles.
Foreign languages are trained by the brain
People who speak two languages constantly switch from one language to another or suppress one to talk to another, so their brain will be trained and ultimately more prepared to compensate for the damage and damage caused by Alzheimer's.
Previous studies on this subject have shown that knowledge of foreign languages helps to delay the clinical manifestations of Alzheimer's disease for up to 5 years. However, this study was the first to find evidence in computer tomography images.
Knowledge of foreign languages can not prevent the development of Alzheimer's disease, and it remains unclear how fast the brain damage develops, first appearing in people who speak different languages.
However, this study made it possible to take another step towards understanding the disease and ways to slow down its development and postpone the frightening symptoms. Before the scientists still have many open questions, for example, it matters whether the age was studied in a foreign language.
Scientists plan to continue the study with the participation of more patients and the use of more accurate data of magnetic resonance imaging.
