Speaking Multiple Languages May Help Keep Your Brain Young
New research suggests that being bilingual or multilingual might help slow down the aging process of the brain. This was highlighted in a study shared at the 2026 Federation of European Neuroscience Societies Forum.
The research involved examining brain activity in hundreds of individuals from the Basque region of Spain who spoke one to four languages, including Spanish, Basque, French, and English. By using artificial intelligence, scientists estimated each person’s “brain age” based on different patterns in brain connectivity.
Interestingly, the study found that people who spoke two languages had brains that seemed around six years younger than those who spoke only one language. Those fluent in three languages appeared about seven years younger, while four-language speakers had brains that looked approximately 13 years younger.
Moreover, the research indicated that those who learned a second language early in life and reached a high level of fluency reaped even greater benefits.
Dr. Tommy Wood, a neuroscientist and author of “The Stimulated Mind,” noted that these findings align with earlier studies, suggesting that knowing multiple languages can safeguard cognitive functions as we age. He emphasizes that it’s never too late to learn a new language, even for those who didn’t grow up learning more than one.
Dr. Wood shared that several studies show improvements in attention and memory for older adults who engage in language learning, even after just a few months. Beyond enhancing cognitive skills, learning a new language can also foster social connections, making it easier to learn and retain new information.
He encouraged adults not to feel discouraged by mistakes when learning, emphasizing that making errors is a vital part of the learning process. “Embrace being a beginner,” Dr. Wood advised. “Challenges and setbacks can actually help you learn faster.”
The researchers did note some limitations in their study. While they adjusted for factors like age, sex, and education, they acknowledged other influences, such as lifestyle and social interactions, might also play a role in their findings.
In conclusion, picking up a new language could be a fun and beneficial way to keep your brain sharp as you age, offering both cognitive and social advantages.
