Circadian Rest-Activity Rhythms, Cognition, and Alzheimer Disease Dementia in Adults With Down Syndrome

Key Points

This study aims to investigate how disruptions in circadian rhythms affect cognitive impairment and dementia symptoms in adults with Down syndrome who have Alzheimer disease.
Examined the association of 24-hour rest-activity rhythms with cognitive performance and dementia symptoms.
Assessed clinical Alzheimer disease status in the population of adults with Down syndrome.
Found a significant association between disrupted circadian rhythms and worsening cognitive function in adults with Down syndrome.
Identified correlations between rest-activity rhythm patterns and severity of dementia symptoms.

Abstract

There is a paucity of research on the role of circadian rhythm disruption in Alzheimer disease (AD)-related cognitive impairments in adults with Down syndrome (DS). The aim of this study was to examine the association of the 24-hour rest-activity rhythm with cognition, dementia symptoms, and clinical AD status in adults with DS.
