Longer Sleep Duration is Linked to More Severe Cognitive and Functional Impairments in Older African Females who are APOE‐ε4 Non‐carriers

Abstract

Background: Blacks are disproportionately affected by Alzheimer’s disease (AD), with rates twice as high as Whites. Etiological factors of AD include behavioral (e.g., sleep) and biological (i.e., genetics) contributors. Both short and long sleep durations are associated with worsened cognitive/functional impairments among older adults.
