For many years, researchers have found that bilingualism appears to ward of the onset of Alzheimer's; this is thought to be caused by the use of two languages building up a cognitive reserve that is utilized in the case of future trauma.
"speaking more than one language might help the brain build up reserves that help it cope better when Alzheimer's symptoms hit."

"[...] bilingual people were diagnosed three to four years after people who spoke one language."

"In the same paper, the researchers also studied how quickly bilinguals and
monolinguals complete tasks while distracted.
They state that research shows
bilinguals may be more adept at switching between tasks and focusing their
attention on a given task." (CBC News, 2013)
Le bilingualism est directement relié au
bien-être de la socièté et de soi-même!
