Knowing more than one language may offer protection against developing mild cognitive decline and dementia, a new study finds.

In a cross-sectional community-based study, researchers evaluated 1,145 older adults (aged ≥60 years) living in urban Bengaluru, India. Participants were classified as monolingual or bilingual, based on the results of the Language Use Questionnaire.
