Foreign language training as cognitive therapy for age-related cognitive decline: A hypothesis for future research

This paper hypothesizes that learning a new language could act as a cognitive therapy for age-related decline. Language learning engages widespread brain networks that overlap with regions affected by aging, potentially building "cognitive reserve," a mental resilience that can delay cognitive decline. Studies suggest cognitive benefits from bilingualism, such as slower aging-related decline and a delay in dementia onset. The authors argue that foreign language programs for older adults could promote brain health through cognitive and social stimulation.

Older adults might consider enrolling in foreign language classes or using language learning apps. These activities are not only mentally stimulating but also offer social interaction, which is beneficial for brain health. Although evidence is promising, more direct research is needed, and benefits may vary based on prior education and engagement levels.
