Can Learning a Foreign Language Prevent Dementia?

The evidence is far less clear than popular media might lead you to believe.

Richard Roberts and Roger Kreuz


Quote:So, if the brain is not a muscle, can it still be exercised? Once again, researchers don’t know for sure. There are now many computer, online, and mobile device applications that claim to be able to “train your brain,” and they typically tap into a variety of cognitive abilities. However, research suggests that although this type of training may improve one’s abilities at the tasks themselves, they don’t seem to improve other abilities. In other words, practicing a letter-detection task will, over time, improve your letter-detection skills, but it will not necessarily enhance your other perceptual abilities. Basically, solving crossword puzzles will make you a better crossword puzzle solver.



Quote:But as encouraging as these kinds of studies are, they still have not established exactly how or why differences between bilinguals and monolinguals exist. Because these studies looked back at the histories of people who were already bilingual, the results can only say that a difference between the two groups was found, but not why that difference occurred. Further research is needed to determine what caused the differences in age of onset between the two groups.

Other studies of successful aging suggest that being connected to one’s community and having plenty of social interaction is also important in forestalling the onset of dementia. Once again, however, the results are far less clear than the popular media might lead you to believe. Older individuals who lead active social lives are, almost by definition, healthier than their counterparts who rarely leave their homes or interact with others. So we can’t really say whether being socially active prevents the onset of dementia, or if people who don’t have dementia are more likely to be socially active.

I was going to say it can't, or else foreigners wouldn't get dementia!

Sad to say, having an active social life and being part of a group activity doesn't guarantee any protection from fading of mental faculties. At least anecdotally I can report this, I can't give statistics on the matter.
