Marwa Morgan, Daily News – Egypt. Being bilingual improves cognitive skills and delays the onset of dementia, independent of education and immigration status, says a recently published study by the American Academy of Neurology. Bilingualism might have been the norm for early human communities, explaining the brain’s capacity to support it, the study authors wrote. People fluent in more than one language show better general cognitive performance, said Dr Thomas Bak of the Centre for Cognitive Aging and Cognitive Epidemiology at the University of Edinburgh, and one of the report’s authors. “The action of shifting between languages according to the changing context acts as mental exercise,” Dr Bak said, adding that the advantages of bilingualism include higher attention than that of monolinguals.
