Background: Recent research suggests that multilingualism may play an important role in enhancing cognitive health. The process of language acquisition constitutes a form of natural brain training, which in turn is thought to increase the neuroplasticity. The aim of this study is to examine the association between multilingualism and cognitive performance. Method: This study utilized cross‐sectional (baseline) data from the Srinivasapura Aging Neuro Senescence and COGnition study (SANSCOG), which is an ongoing community‐based, longitudinal aging cohort study conducted in a rural setting in Southern India. Study participants were dementia‐free, aging adults (45 years and above) from the villages of Srinivaspura. This study site is located in the state of Karnataka, close to the border of an adjoining state, Andhra Pradesh. The subjects are separated into two groups, namely monolinguals, participants knowing one language and multilinguals, participants knowing more than one language, to assess if language has any role in cognitive performance. The cognitive performance of the participants was assessed using Hindi Mental State Examination (HMSE) and Clinical Dementia Rating (CDR). A total of 3283 subjects for HMSE, and 3634 for CDR, including both normal and cognitively impaired subjects were considered for the study. Dementia free patients with HMSE scores below 24 and CDR scores of 0.5 are considered as the inclusion criteria. The data analysis was performed using chi‐square test. Result: The study showed a statistical significance for the association between number of languages spoken and cognition. Multilinguals achieved better cognitive scores, which shows their greater flexibility in cognition. The p value and chi‐square (p value:< 0.001; chi‐square: 59.448) of monolinguals and HMSE scores shows that the analysed data is significant. The odds ratio is 2.562 and it indicates that monolinguals have higher odds of developing cognitive decline than multilinguals. The analysis indicates that exposure to multiple languages has the upper hand, as it is thought to enhance the brain function. Conclusion: This study highlights that learning multiple languages might have a profound impact on cognitive health, thereby reducing the likelihood of developing cognitive impairment.
