Prior estimates of dementia prevalence in India were based on samples from selected communities, inadequately representing the national and state populations.

From the Longitudinal Aging Study in India (LASI) we recruited a sample of adults ages 60+ and administered a rich battery of neuropsychological tests and an informant interview in 2018 through 2020.
