Sleep and related disorders

This study uses genomic structural equation modelling to assess the genetic overlap between insomnia, depression, and anxiety, finding insomnia is the best-supported location of the genetic overlap.

In 2,952 sleep-clinic patients, difficulty initiating sleep (DIS) came with longer sleep latency and later deep-sleep build-up; in unmedicated DIS patients, depressive symptoms accompanied a less wake-like sleep onset.

This study examines sleep disturbances in Lennox-Gastaut Syndrome patients and their caregivers, finding significant impacts on caregivers' sleep and highlighting the need for family-centered approaches.

This study shows that active bed temperature regulation affects sleep depth, autonomic activity, and EEG patterns, with varying effects depending on cooling or heating settings.

This study examines the bidirectional relationship between sleep and food intake using naturalistic data, finding that timing, not quality or composition, is the primary factor.

This paper validates a spectral sleep scoring method for pediatric sleep, showing high agreement with visual scoring and providing clinically relevant insights.

This study uses Mendelian randomization to examine the lifecourse effects of childhood and adulthood adiposity on sleep health outcomes, finding that adult adiposity is a risk factor for insomnia while childhood adiposity may have protective effects when maintained in adulthood.

The paper examines sleep discrepancy between self-reports and objective measurements in a healthy population, finding that questionnaires are less accurate than daily diaries, and sleep discrepancy is influenced by non-pathological factors.

This study examines the relationship between sleep and anxiety in Chinese empty-nest older adults, finding that poor sleep quality and short sleep duration are independent risk factors, with physical exercise and social participation mediating these associations.

The paper investigates whether alexithymia's association with poor sleep quality reflects physiological changes, specific perception issues, or non-specific negative affectivity, finding the latter.

This study examines night-to-night variability in sleep patterns using EEG data over one year, finding that macrostructural patterns are relatively stable while temporal alignment varies significantly.

This study examines how sleep loss, psychological distress, and physical inactivity independently and cumulatively affect cognitive failures in young adults, finding additive effects rather than compensatory ones.

The paper identifies 260 genes associated with sleep phenotypes using rare coding variants from large-scale sequencing data, revealing distinct genetic architectures and biological mechanisms across different sleep measurements.

This study examines the effects of co-sleeping with dogs, cats, or children on sleep, cardiorespiratory physiology, and next-day activity in adults, finding modest physiological benefits and mixed sleep outcomes.

This study shows that music helps adults with sleep-onset insomnia fall asleep faster, but neural synchronization to the beat of the music is not the main reason for this effect.

This paper presents a grid-search framework for calibrating actigraphy sleep detection algorithms, showing it can replace manual tuning with improved reproducibility and small performance gains.

The paper examines sleep initiation in children with neurodevelopmental conditions, finding weaker neural and physiological transitions linked to longer sleep onset latencies.

This study investigates memory control impairments in insomnia disorder, finding reduced suppression-induced forgetting and altered electrophysiological responses during memory suppression tasks.

This study identifies metabolites linked to insomnia symptoms and develops risk scores predicting cognitive decline in Hispanic/Latino adults.

The paper examines sex differences in sleep EEG patterns among children with and without neurodevelopmental disorders, finding significant sex-based variations in sleep features but not in brain age predictions.

This study examines how non-pathogenic CAG repeats in HTT, ATXN3, and CACNA1A genes affect sleep outcomes, finding sex- and depression-specific associations.

This study identifies genetic associations for multiple sleep disorders and medications in over 1.6 million individuals, revealing shared and unique genetic factors across sleep traits.

This study examines how variations in sleep within and between older adults relate to cognitive performance, finding that sleep duration and efficiency affect reaction time but not other cognitive functions.

This study uses wearable EEG to examine age trends in sleep architecture across adolescence, finding some replication of established age effects but limited statistical significance for some measures.

This study examines how sleep and mental health independently affect cognitive performance in university students using cognitive tests and sleep monitoring.

This study uses subcutaneous EEG to track sleep patterns over a year, finding that external factors like season, temperature, and weekends influence sleep duration and timing.

This study uses large-scale wearable data to show geographic patterns in sleep timing and duration, influenced by solar and social factors.

This study evaluates if smartwatch-delivered sensory stimulation during home sleep increases frontal delta power and improves next-day behavioral outcomes.

This study tracks sleep changes in Toba/Qom communities over two decades, finding delayed sleep timing and reduced sleep duration linked to modernization factors beyond just electricity and digital devices.

This paper introduces a compositional and temporal framework for analyzing sleep architecture by addressing binning window selection and compositional data analysis through isometric log-ratio transformation.
