Boost Your Brain Health: A Randomized, Controlled Trial Comparing 3 Online, Multidomain Dementia Risk Reduction Interventions

Abstract

Background: Nearly 1 in 3 older adults are living with mild cognitive impairment (MCI) or subjective cognitive decline (SCD), which places them at increased risk for Alzheimer's disease and related dementias (ADRD). Although multi‐domain interventions may reduce dementia risk, most are time‐intensive and difficult to scale.
