Study finds bilingualism may delay brain aging by up to 13 years

Researchers examined whether acquiring a new language influences brain aging. The study compared individuals who learned additional languages with those who did not. Findings suggest that bilingual or multilingual speakers show signs of younger brain tissue. The estimated reduction in brain age reaches up to 13 years for language learners. Results were reported in a 2026 scientific publication. Scientists attribute the effect to increased cognitive stimulation from language use. The discovery highlights language learning as a potential non‑pharmacological intervention. Experts recommend incorporating language study into lifelong learning plans. Ongoing research will explore the mechanisms behind the observed delay.
