DOI: 10.1093/sleep/zsab072.044
Abstract: Alterations in sleep and circadian rhythms are common in persons with Alzheimer’s disease (AD) dementia, but the nature of such changes in the early phases of AD remains unclear. This study compared sleep and circadian… read more here.

DOI: 10.1093/sleep/zsac027
Abstract: STUDY OBJECTIVES Age-related cataract decreases light transmission at the most sensitive spectrum for circadian photoentrainment, with negative ramifications for human health. Here, we assessed whether intraocular lens replacement (IOL) in older patients with previous cataract… read more here.

DOI: 10.1093/sleep/zsad077.0099
Abstract: In early childhood, irregular sleep schedules that may promote circadian rhythm misalignment predict greater weight gain. However, circadian rest-activity (CRA) rhythmicity in infancy in relation to growth is understudied. The aim of the present study… read more here.

DOI: 10.1093/sleep/zsad077.0712
Abstract: Several studies suggest that sleep and circadian rhythm disruptions, and physical activity changes may serve as risk factors for the occurrence of Parkinson’s disease and its prodromal features. Obstructive sleep apnea (OSA) is commonly found… read more here.

Circadian rest‐activity rhythm and longitudinal brain changes underlying late‐life cognitive decline
Sign Up to like & getrecommendations! Published in 2022 at "Psychiatry and Clinical Neurosciences"
DOI: 10.1111/pcn.13521
Abstract: The neurobiological substrates underlying the relationship of circadian rest‐activity rhythm (RAR) alteration with accelerated late‐life cognitive decline are not clearly understood. In the present study, the longitudinal relationship of objectively measured circadian RAR with in… read more here.

DOI: 10.30773/pi.2021.0395
Abstract: Objective Data processing in analysis of circadian rhythm was performed in various ways. However, there was a lack of evidence for the optimal analysis of circadian rest-activity rhythm. Therefore, we aimed to perform mathematical simulations… read more here.
