It is by now widely known that bilingualism delays the onset of dementia. What is less widely known is the fact that this knowledge is almost exclusively derived from Canadian research conducted by Ellen Bialystok and her team (e.g., Bialystock et al., 2007). The data for these studies come from comparing monolingual English-speaking native-born Canadian dementia sufferers with their bilingual counterparts. The bilinguals are all migrants to Canada who had learned English during adolescence or young adulthood and come from a variety of first-language backgrounds with Central and Eastern Europeans predominating.
