Relationship between bilingualism and Alzheimer’s

Abstract

This paper compiles several studies that show the relationship between bilingualism and Alzheimer's disease. Studies here compiled were independently carried out between 1991 and 2012 in the United States, in Canada, in the United Kingdom, in India and in Sweden. The paper reviews the results of studies that show that the time elapsed between early Alzheimer's diagnosis and the actual appearance of telltale symptom is up to five years longer in elderly bilinguals than in elderly monolinguals. Cradle bilinguals benefit most from bilingualism but language learning in adulthood can also benefits speakers. These and related scientific facts are compiled. Reports of scientific research are presented, and its conclusions are summarized.
