It appears speaking more than two languages has a protective effect on memory in elder people, who practice foreign languages over their lifetime or at the time of the study ,” said Magali Perquin, a researcher from the Public Research Center for Health in Luxembourg.The study involved 230 men and women with an average age of 73 who had spoken or currently spoke two to seven languages.Researchers discovered that those people, who spoke four or more languages, were five times less likely to develop cognitive problems, compared to those people who only spoke two languages.People who spoke three languages were three times less likely to have cognitive problems compared to people who spoke two languages.Perquin said further studies were needed to try to confirm these things. Further studies were also needed to determine “whether the protection is limited to thinking skills related to language, or if it also goes beyond that and benefits other areas of cognition.”
