Incident Alzheimer’s dementia analyses included participants free of Alzheimer’s dementia at baseline, with follow-up neurocognitive assessments, and moderate nap durations (15 min to 4 h/day). AD pathology analyses included participants who died within three years of their last actigraphy assessment and had moderate nap durations. The two sub-samples (n = 936 and n = 320) overlap partially and are not entirely distinct; n = 320 is not a subset of n = 936.
