Prior studies from other settings suggest that VI may be a modifiable risk factor for cognitive decline and dementia. However, to date, no studies have examined the association of impaired visual acuity and cognition in India.<h4>Methods</h4>A total of 3,784 participants in wave 1 of the population-based Diagnostic Assessment of Dementia for the Longitudinal Aging Study in India underwent visual acuity testing and a cognitive test battery. Multivariable linear regression was used to model the cross-sectional associations of mild (<6/12-6/16), moderate (<6/18-6/60), and severe visual acuity impairment/blindness (<6/60) with cognitive performNeuroepidemiologyThe Association of Cognitive and Visual Function in a Nationally Representative Study of Older Adults in India.PMC8095156U01 AG064948RF1 AG055273K23 EY027848R01 AG051125Chien SNdukwe TEhrlich JRLee JfalseThe Association of Cognitive and Visual Function in a Nationally Representative Study of Older Adults in India.<h4>Introduction</h4>Due to population aging, India is poised to experience a large increase in the burden of both dementia and vision impairment (VI).
