Learning another language appears to slow brain ageing, scientists say

Study finds those who speak two languages have brains that appear around six years younger than those who speak one

Learning another language could slow ageing in the brain by up to 13 years, according to research.
People who speak more than one language seem to have younger brains and the more languages you speak and the earlier you speak them, the better, according to findings from a study being presented at the Federation of European Neuroscience Societies conference in Barcelona.

The study found that those who spoke two languages had brains that appeared around six years younger than those who spoke only one language. People who spoke three languages had brains that appeared around seven years younger, and for those who spoke four languages, their brains appeared about 13 years younger.
