andTaiwanese). Thuswe performedan epidemiology study inTaiwan to study the relationship between bilingualism and dementia.Methods: In this study, we investigate the language profile, MMSE, AD8 of 499 people in a local community (Taishan) of Taiwan. People in Taishan who are older than 70 years old were recruited since February, 2011 to December, 2011. 73 (14.6%) of them are bilinguals, 426 (85.4%) are monolinguals. Clinical neurologist confirms the diagnosis of dementia in all subjects. Results: The results reveal no significant difference in dementia prevalence between bilingual (16.4%) and monolingual (15.0%) population. But age of bilinguals is older than monolinguals (78.4 v.s. 73.4). Bilinguals show significant higher MMSE results (mean: 24.5) compare to monolinguals (mean: 22.7). Conclusions: Although the dementia prevalence didn’t show significant difference between the 2 groups, there is 5 years difference between age of bilinguals and monolinguals in this study. This suggests s that bilingualism may still have some protective effects on dementia. Besides, bilingualism itself does have advantage on MMSE scores, especially in sub-items of attention and constructional praxis. More research works have to be done to demonstrate the meaning and possible implication of language effects on dementia.
