Learning a second language around age 10 can boost brainpower, according to a new study published in the Proceedings of the National Academy of Sciences.
During the study, researchers studied brain scans from 20 people, all around the age of 30, who had lived in Britain for at least 13 months; and had all started learning English as a second language around age 10. Their imaging analyses were compared to 25 people of the same age who spoke only English.
AdvertisementResearchers found that people who began learning English around age 10, meaning they heard and used it in daily life, showed improvements in the structure of the brain's white matter compared to people who grew up speaking only English and did not learn a second language. These higher levels of structural integrity were seen in areas responsible for language learning and semantic processing.
Study lead, Christos Pliatsikas of the University of Kent School of Psychology, said, "Everyday handling of more than one language, functions as an intensive cognitive stimulation that benefits specific language-related brain structures by preserving their integrity, and therefore it protects them against deterioration in older age."
