Learning Another Language May Slow Brain Aging

Speaking multiple languages could slow brain aging and prevent cognitive decline, a study of 80,000+ people found.

Why it matters

  • Multilingualism may delay cognitive aging.
  • Previous studies had small samples and unreliable methods.

By the numbers

  • Over 80,000 participants aged 51-90 across 27 European countries.
  • Multilingual people are half as likely to show accelerated aging signs.

The big picture

  • Learning additional languages may protect brain health.
  • Could influence policymakers to promote language learning.

What they're saying

  • Study's scale strengthens link between multilingualism and slower aging.
  • Experts suggest starting with easier languages to build confidence.

Caveats

  • Language proficiency was self-reported.
  • Future research should include more diverse populations.

What’s next

  • Policymakers might promote language learning in education.
  • Future studies could expand to non-European populations.
