One of the most important aspect of brain health is to prevent neurodegenerative diseases, with Alzheimer’s disease near or at the top of the list. A new study further strengthens the findings that being bilingual has a very powerful benefit of delaying the average age of Alzheimer’s disease onset. A good point in this article is that the researchers thinks that it is the increased mental capacity brought on by learning two languages that reduces or delays Alzheimer’s symptoms:
The authors of the study, which was published in the journal Neurology, stress that they are not indicating that bilingualism prevents Alzheimer’s disease or other forms of dementia, but they do suggest that the ability to speak multiple languages might increase a person’s mental capacity. Thus, while bilingual individuals may still display symptoms of dementia, their linguistic abilities may somehow compensate for their condition and thereby delay or lessen the symptoms of Alzheimer’s, including memory loss and confusion.
