Rest–Activity Rhythm Characteristics and Cognitive Function in Cognitively Healthy Older Adults

Our study contributes novel insights into the intricate relationship between RAR parameters and cognitive function in later life adults. We found positive associations between RAR mesor and processing speed as well as pseudo-F-statistics and memory in later life adults. Significance/Implications: These findings have potential implications for both research and clinical practice. For researchers, there is a need for further exploration of the complex associations between RAR and cognitive health, preferably through large-scale, diverse, longitudinal studies. From a practical perspective, understanding these associations may guide the development of interventions aimed at promoting cognitive health.
