Speaking more than one language can help delay dementia symptoms, study finds

Have you been keeping up on your Duolingo streak? New research suggests that learning a second language could play a role in keeping the mind younger and healthier for longer. A study published in the journal "Nature Aging" found that people who speak two or more languages were more likely to see delayed symptoms of dementia. The World's Host Carolyn Beeler learned more from Lucia Amoruso, one of the main authors of the research. She's a psychologist with The Basque Center on Cognition, Brain and Language based in San Sebastian, Spain.
