Almost as fast as my recent blog on bilingualism and the benefit to the human brain was posted I read a research report that learning a third language can help to reduce risk of dementia. This research from the Public Center for Health in Luxembourg does suggest more languages equal a lower risk of cognitive impairment. The research was to be presented at the American Academy of Neurology in April
Seniors who practice foreign languages over their lifetime and have the ability to speak more than two languages demonstrate the cognitive protection. The research studied 230 people with average age of 73 and findings support the growing body of literature that describes cognitive reserve thought to be developed by engagement in the complex and novel.
Similar studies have shown the health promoting effects of language development and in this case development of more than two languages. In this particular study, participants who had spoken three languages were significantly more likely to be protected against cognitive impairment. Those with four languages were even better off in terms of cognitive health. Those with five or more languages had similar protection to mastering four languages.
We all might want to get started on our second, third, or fourth language today!
