Abstract  

Research in neurolinguistics in the past 50 years has demonstrated the cognitive effects of bilingualism (or multilingualism). In this review we focus on the research over the past 10 years on the effect of bilingual or multilingual experiences in resisting Alzheimer's disease (AD). The possible neural mechanisms underlying such effect are explored under the theory of Cognitive Reserve. Some unsolved questions about language types, proficiency, age of learning and research methodologies are also raised for further discussion. The implication of these findings in helping prevent or delay AD, in promoting second language learning and teaching, and in offering insights into future research on interdisciplinary linguistics are also discussed.

Keywords bilingualism (multilingualism)      Alzheimer's disease      cognitive reserve      interdisciplinary linguistics
