Bilingualism May Protect from Alzheimer’s Disease and MCI

A new study, published in the journal Neuropsychologia, finds that bilingualism makes changes in brain structure that are associated with resilience against the Alzheimer’s disease and mild cognitive impairment (MCI).bilingualism

The researchers included the following categories of participants: multilingual with MCI (34), monolingual with MCI (34), multilingual with the Alzheimer’s disease (13), monolingual with the Alzheimer’s disease (13). Having analyzed the received data, the researchers found that both multilingual patients with MCI and Alzheimer’s disease patients had thicker cortex than monolingual patients.

Lead study author Natalie Phillips, a professor in the Department of Psychology at Concordia University in Quebec, Canada, says: “Our new study contributes to the hypothesis that having two languages exercises specific brain regions and can increase cortical thickness and gray matter density.”
