Mental Aging may Be Avoided by Acquiring Multi-Linguistic Skills

Kids who speak a second or third language may have an unexpected advantage later in life, a new study has found.

A new study has found that children who acquire skills to learn multiple languages may be able to put off mental aging in later life.

According to Tel Aviv University researchers, knowing and speaking many languages may protect the brain against the effects of aging.

Dr. Gitit Kave, a clinical neuro-psychologist from the Herczeg Institute on Aging at Tel Aviv University, together with her colleagues Nitza Eyal, Aviva Shorek, and Jiska Cohen-Manfield, recently discovered that senior citizens who speak more languages test for better cognitive functioning.

However, Kave says that one should approach these findings with caution.

"There is no sure-fire recipe for avoiding the pitfalls of mental aging. But using a second or third language may help prolong the good years," she said.

A person who speaks more languages is likely to be more clear-minded at an older age, she says, in effect "exercising" his or her brain more than those who are monolingual. Languages may create new links in the brain, contributing to this strengthening effect.

The research was based on a survey taken in 1989 on people between the ages of 75 and 95. Each person was asked how many languages he or she knew, what his or her mother tongue was, and which language he or she spoke best.

The researchers compared bilingual speakers to tri- and multilingual speakers.

Analyzing the results, the researchers found that the more languages a person spoke, the better his or her cognitive state was.

A person's level of education was also strongly associated with cognitive state, but the number of languages contributed to the prediction of cognitive fitness beyond the effect of education alone.

Although the easiest way to explain the findings was to point out the relationship between higher education and number of languages, this was not the whole story.

In fact, Dr. Kave says, "We found that more languages were most significantly correlated with cognitive state in those people who had no education at all."

Dr. Kave, however, adds a note when interpreting the statistics.

"The study looked at the final result and not the cause," she said.

The study is published in the journal Psychology and Aging.
