People who speak several languages may have brains that age more slowly, with four-language speakers showing brains that appeared about 13 years younger than those of monolinguals. Starting earlier and becoming highly fluent were also linked to a stronger effect.
The new findings suggest that multilingual experience may help offset some of those age-related changes. People who spoke more languages tended to have younger-looking brains, and the effect also appeared stronger among those who learned another language earlier and became more proficient.
