Brain Benefits for the Bilingual

  

If you speak two languages, you may have an advantage over those of us who speak only one.  A new study finds people who are bilingual may have extra protection against Alzheimer's disease.

 Two languages may be better than one when it comes to protecting your brain from Alzheimer's disease, recent research suggests.
The research focuses mostly on people who are truly bilingual and have been for many years, but scientists say learning a new language later in life might help.

Ellen Bialystok, a psychologist at York University in Toronto, studied 450 people with Alzheimer's. Those who were bilingual were diagnosed between four and five years later than those who spoke only one language.
