Can Learning a New Language Support Brain Health as You Age?

Although the way people learn languages changes with age, adults can learn new languages throughout their lives. Adults and children bring different strengths to language learning. Children often have an advantage in some aspects of pronunciation and grammar, while adults typically bring a larger vocabulary and more developed learning strategies.

Research involving older adults suggests that learning a language may provide cognitive benefits, although the findings are mixed. Any potential benefits may come from the learning process itself rather than from achieving fluency. Learning a language is an ongoing challenge that requires people to keep learning, practicing and adapting.

Language learning may also offer social benefits. Learning another language can deepen cultural understanding, improve communication and encourage empathy for other people’s perspectives and experiences. It can also connect people from different linguistic and cultural backgrounds, creating opportunities for conversation and friendship.

There is no established formula for how much language learning is needed to obtain these benefits. Studies have examined approaches ranging from intensive classroom instruction to short, daily sessions with a language-learning app over several weeks or months. The key may not be a specific number of hours, but a commitment to consistently engaging in challenging activities such as learning a new language.

How language learning may build cognitive resilience

Learning another language is not a miracle cure for aging, and it does not guarantee protection against Alzheimer’s disease or other forms of dementia.

However, it is an unusually rich form of mental activity.

Perhaps the most useful way to think about language learning is not as a way to keep the brain young, but as a way to support cognitive resilience—the ability to learn, adapt and continue functioning despite age-related changes.

Although the brain inevitably changes as people age, its ability to learn remains throughout life. Keeping the brain focused on new and demanding activities may contribute to its resilience.
