Benefit of being bilingual


WATERLOO (KWWL) -- Want to protect against the effects of Alzheimer's?

You might want to learn a second language.

Canadian researchers tested about 450 Alzheimer's patients -- half of whom were bilingual.

They all had similar levels of cognitive impairment ... but those who were bilingual had been diagnosed an average of four years after those who spoke only one language.

Researchers think it's because people who speak more languages use a specific part of their brain more often - allowing them to better cope with the effects of Alzheimer's.
