Abstract

Background Alzheimer's disease (AD) in those who are bilingual is becoming increasingly prevalent in modern society, yet little is known about the impact of AD on the bilingual's two languages. Aims To gather information from the available literature on AD and bilingual individuals. Methods & Procedures The first author searched three electronic databases for relevant articles and retrieved 186 articles. Nine articles met the inclusion criteria and were selected for this review. Various research methods employed in assessing language changes in bilingual individuals with AD were captured. Main Contribution Preliminary findings suggest that both controls and bilingual individuals with Alzheimer's disease (BIAD) were more able on language-related tasks in their dominant language compared with their non-dominant language. The current literature would suggest that both languages in bilingual individuals are equally affected by AD; however, there is room to explore preliminary data on the fact that the non-dominant language, and indeed the dominant language, is more sensitive to AD. Conclusions & Implications More robust, clinically relevant research designs that test current theoretical frameworks are needed to inform the development of appropriate assessments, diagnosis and person-centred care for bilingual individuals with AD.
