An international team, including Spanish researchers, has analyzed data from more than 86,000 people aged 51 to 90 from 27 European countries and concluded that multilingualism—the habit of speaking more than one language—is associated with a reduced risk of accelerated aging. According to the authors, who published their findings in the journal Nature Aging, “these findings could inform educational and public health policies aimed at promoting cognitive resilience and functional capacity in older populations.”

A study in England has found a link between increased exposure to air pollution during early life and the risk of developing psychotic disorders and depression during youth. In addition, greater exposure to noise during childhood and adolescence was associated with an increased risk of anxiety. The results of the study, which collected data from more than 9,000 people, are published in the journal JAMA Network Open.
