BRS/The Brain Resilience Study: Circadian rhythm amplitude is associated with cognitive performance in older adults

Key Points

The aim is to explore the association between circadian rhythm parameters and cognitive performance in older adults.
Analyzed circadian parameters using actigraphy data.
Compared cognitively healthy older adults with those at cognitive risk.
Data sourced from the Brain Resilience Study.
Circadian rhythm amplitude differences observed between groups.
Association found between better cognitive performance and healthier circadian patterns.

Abstract

Poster created for Cognitive Neuroscience Society (CNS) 2026 Annual Meeting. Circadian rhythm disruption is an early feature of Alzheimer's disease, yet its relationship to cognitive vulnerability in non-clinical populations remains poorly understood. In this study, we examined whether actigraphy-derived circadian parameters differ between cognitively healthy older adults and those at cognitive risk, using data from the Brain Resilience Study.
