According to a new paper from Canadian researchers, bilingual individuals have a lower risk of developing Alzheimer’s disease and other cognitive impairments. And though researchers can’t say exactly why, one theory is that being able to speak two languages requires a person to always have both languages available in their mind. The constant conflict inside the brain exercises regions critical for general attention and boosts cognitive reserves. In addition to a lowered risk of developing dementia, studies have shown that bilinguals are also able to function and cope with diseases like Alzheimer’s longer than people who don’t speak a second language. More than half of the world’s population is bilingual, though only 20 percent of Americans speak a language other than English. More here.
