About The Study: This cohort study of older participants found accelerated decreases in cognition among individuals hospitalized for SARS-CoV-2 infection, but not nonhospitalized infection, in comparison with individuals not yet infected. These findings suggest that avoiding severe SARS-CoV-2 infection could help preserve cognitive function among older adults.
