Learning a second language may not only help you on a trip overseas.
A new study finds becoming bilingual may delay the onset of three types of dementia.
Researchers at the Nizam’s Institute of Medical Sciences in Hyderabad, India studied nearly 648 people. 240 of them had Alzheimer’s disease, while the remaining participants had other types of dementia including: Frontotemporal and vascular dementia. 391 people spoke two or more languages.
They found people who spoke two languages had a later onset of Alzheimer’s disease, frontotemporal dementia, and vascular dementia.
It’s the largest study on this topic to date and researchers say the results offer strong evidence for the protective effect of bilingualism against dementia.
