In this blog, we have presented several benefits of being bilingual. We have also shown that bilinguals’ brains behave somewhat differently (in a positive way) when compared to monolinguals’. In addition, in a fairly new experiment carried out by Jubin Abutalebi of the Vita-Salute San Raffaele University, the relationship between being bilingual and a slower development of Alzheimer’s disease (AD) has been studied.

They found that bilinguals develop AD slower than monolinguals, and the provide a possible explanation for that. First of all, in previous studies it has been shown that bilinguals with AD have more atrophy in the brain than monolinguals with the same disease. However, it seems that AD takes more time to develop in bilinguals’ brain because they have “better connectivity between intact neurons”. Abutalebi, however, mentions that “only those who really use the two languages are protected”. In any case, the findings in this study are undoubtedly crucial for future investigations.
