Multilingual profiles and their association with cognition and brain structure among older Indian adults
Among linguistically and socioeconomically diverse older multilingual Indian adults, active multilingualism (i.e., early AoA, high L2 proficiency, and daily dual language use) was associated with better cognitive functioning. Active multilingualism might also confer cognitive reserve given the weakened associations between hippocampal volume and cognition. However, future studies with larger neuroimaging sample sizes and longitudinal follow-up are required to further evaluate brain-cognition relationships among aging multilingual adults.
