Multilingualism Protects From Alzheimer

Multilingualism Protects From Alzheimer

(ePharmaNews) - It seems that the multiplicity of languages within communities and students exposed to different cultures carries benefits other than the expansion of the understanding and acceptance of others, as it also protects against future diseases such as Dementia.


In a study published last month in Trends in Cognitive Sciences journal, Canadian researchers found that onset of dementia delays several years in those who are fluent in two or more languages, compared to their peers who only speak one language.
They propose that the lifelong need to monitor two languages in order to select the appropriate one leads to a constant recruitment of brain regions critical for attention and cognitive control. Such constant recruitment may, in turn, strengthen certain brain regions and help ward off the encroachment of dementia.
“It has to do with cognitive reserve,” Bialystok the famous psychologist and the lead author of the study says, "a building up of resilience that comes from certain experience that allows you to cope.”
"If what you have to cope with is cognitive impairment from nasty things like Alzheimer's disease, the finding is that [bilinguals] can appear to function for a longer time than they otherwise would," she said. "Cognitive reserve is an extra resource that enables you to keep functioning."
"We know that if you know two languages, and that there are two languages you could be speaking at any time, then both of those languages are always active - they're always kind of 'available' in your mind," she said.
"That means that every time you want to say something or understand something or write something, there's potential interference from the other language."
It is worth mentioning that the researches on multilingualism in adults are still relatively few, compared to researches that have examined this issue in children, the latest one was a news topic published few weeks ago concluding that children who grow up in a bilingualism culture have a speak delay and in the acquisition of linguistic knowledge compared to their peers who speak only one language. Anyway, it seems that the delay of speak in a child in such cases may benefits him/her eventually!
