Speaking Multiple Languages Associated With Slower Brain Aging, Study Suggests

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.

New research suggests that command of multiple languages may protect against cognitive decline, with speakers of four languages exhibiting brain characteristics roughly 13 years younger than those of people who speak only one language. The findings add to growing evidence that linguistic diversity offers measurable neurological benefits across the lifespan.

The strength of the protective effect appears tied to two key factors: the age at which multilingualism begins and the degree of fluency achieved in each language. Individuals who started learning additional languages earlier and developed high proficiency demonstrated the most pronounced slowing of brain aging.

The research underscores how cognitive engagement through language learning may build neural resilience, potentially delaying age-related deterioration in brain structure and function. Scientists continue investigating the mechanisms by which multilingualism influences brain health and longevity.
