Multilingualism linked to slower brain aging in new study

New research presented by the Federation of European Neuroscience Societies (FENS) suggests a potential link between multilingualism and slower rates of brain aging. The study examined residents of the Basque Country in Spain, where individuals frequently speak multiple languages, including Spanish, Basque, French, and English.

Researchers developed a model to estimate brain age based on linguistic experience. Findings indicated that individuals proficient in four languages showed an estimated brain age approximately 13 years younger than those who speak only one language.

Scientists clarified that these results demonstrate a correlation rather than proving that multilingualism is the direct cause of delayed brain aging. The study focuses on cognitive resilience, which is the brain's ability to maintain functionality despite age-related changes in neural networks.
