Speaking multiple languages linked to slower brain aging
A study presented at the FENS Forum 2026 found that people who speak several languages tend to have brains that appear younger than their chronological age. Those fluent in four languages showed brains about 13 years younger than monolinguals, with earlier learning and higher proficiency strengthening the effect. The research used magnetoencephalography and AI to estimate brain age in over 700 participants.
