The American Academy of Neurology recently published an interesting study. Newswise reports on it:
Newswise — MINNEAPOLIS – In the largest study on the topic to date, research shows that speaking a second language may delay the onset of three types of dementias. The research is published in the November 6, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.
The study found that people who spoke two languages developed dementia four and a half years later than people who only spoke one language.
“Our study is the first to report an advantage of speaking two languages in people who are unable to read, suggesting that a person’s level of education is not a sufficient explanation for this difference,” said study author Suvarna Alladi, DM, with Nizam’s Institute of Medical Sciences in Hyderabad, India. “Speaking more than one language is thought to lead to better development of the areas of the brain that handle executive functions and attention tasks, which may help protect from the onset of dementia.”
