🧠Speaking more than one language slows cognitive decline.
Children (and adults) who speak and use multiple languages throughout life may give their brains a powerful form of mental exercise — potentially slowing brain aging and reducing risk of cognitive decline.
A major recent study of over 86,000 older adults across 27 European countries found that multilingual individuals were significantly less likely to show signs of accelerated “biobehavioral aging” compared to monolingual peers.
The researchers propose that the constant mental juggling required by switching between languages — selecting one language, suppressing interference from others, and managing shifting vocabularies — strengthens neural networks involved in memory, attention, and executive control.
Over time, these reinforced pathways may build what scientists call “cognitive reserve,” helping the brain remain resilient in the face of age-related change.
