Summary: The study aimed to examine the effects of age, menopausal status, and symptoms on sleep patterns and circadian rhythms in midlife women. Premenopausal women had the most unstable day-to-day rhythms, and women with more severe symptoms experienced greater sleep problems. Psychological symptoms were the strongest predictors for all sleep parameters.

Summary: This study found that longer sleep onset latency and lower sleep efficiency were associated with lower cognitive reserve. However, total sleep time and wake after sleep onset were not significantly associated with cognitive reserve. The 24-hour activity rhythm was also not significantly associated with cognitive reserve.

Summary: This study found an association between daytime rest and 24-hour rest probability profiles, circadian timing, and neurobehavioral outcomes in healthy older adults. The results suggest that increasing daytime rest frequency is related to more fragmented nighttime rest and lower episodic memory performance.

Summary: The study found that Parkinson's disease (PD) patients exhibit a phase advance and amplitude reduction in their circadian activity rhythm (CAR), and as the PD stage progresses, these effects become more pronounced.

Summary: The present study evaluates the effect of exogenous melatonin on sleep and circadian parameters in patients with bipolar disorder and delayed sleep-wake phase disorder. Results indicate that personalized treatment with exogenous melatonin can modify self-reported chronotype, sleep onset time, and sleep efficiency and duration in patients with comorbid bipolar disorder and delayed sleep-wake phase disorder, suggesting potential efficacy in improving sleep patterns in this population.

Summary: This article reviews the relationship between circadian rhythm disturbance and kidney stone disease (KSD), summarizing the risk factors and treatment methods. The results indicate that KSD is associated with systemic disorders such as metabolic syndrome, inflammatory bowel disease, and microbiome dysbiosis, and some chronotherapies have been proven effective.

Summary: This study found that patients with Delayed Sleep Phase Disorder (DSPD) exhibited similar distribution characteristics of resting period durations as patients with Major Depressive Disorder (MDD), with both showing a power-law distribution form and lower scaling exponents. This suggests the existence of similar pathophysiology between DSPD and MDD.

Summary: This review examines the impact of sleep conditions on balance control and finds that acute and chronic sleep deprivation, as well as poor sleep quality, have negative effects on postural control. Additionally, time awake worsens balance control and is linked to chronotype and circadian rhythms.

Summary: The disrupted circadian rest-activity rhythms in older adults are associated with a higher burden of cerebral small vessel disease, influencing the severity of arteriolosclerosis, atherosclerosis, and infarcts.

Summary: The study explored the relationship between sleep and fatigue, finding that self-reported nightly sleep quality significantly predicted subsequent daily fatigue ratings, while total sleep time was a significant predictor of fatigue within participants. Additionally, unhelpful sleep beliefs and rumination about fatigue mediated the relationship between insomnia and fatigue reporting.

Summary: This study aimed to examine the association between 24-hour skin temperature variation and sleep quality. The results showed that skin temperature with higher regularity and rhythm amplitudes was associated with better sleep quality. Specifically, higher skin temperature regularity was correlated with higher sleep efficiency and longer total sleep time, and lower wake after sleep onset.

Summary: Sleep quality is negatively affected in patients with cluster headache (CH) both during cluster bouts and in remission, with symptoms of prolonged sleep latency, increased time in bed, and decreased sense of being well rested.

Summary: This study investigated the association between light exposure in daily life and circadian activity rhythms in patients with bipolar disorder. The results showed that daytime light exposure was positively associated with circadian activity rhythms, while nighttime light exposure was negatively associated.

Summary: The relationship between mood instability, impulsivity, sleep disturbances, and circadian rhythm dysfunction is not well understood. While there is emerging evidence of a positive association between disturbances in circadian rest-activity patterns and delayed sleep timing with mood instability and impulsivity, the association with sleep duration, efficiency, and quality is inconsistent. Future research should focus on longitudinal intra-individual associations to establish the directionality between these measures and may lead to the development of chronotherapeutic interventions for various psychiatric disorders.

Summary: This study found that individuals with autism have different melatonin secretion patterns compared to neurotypical individuals, and these patterns are related to sleep and circadian parameters. These findings are important for understanding sleep problems in autism spectrum disorder.
