Sleep and related disorders

This study examines how lifestyle changes in Indigenous Orang Asli communities in Malaysia affect sleep patterns and circadian rhythms, finding delayed timing and shorter duration with improved quality.

This study examines how sex and insomnia affect NREM brain oscillations beyond aging, finding sex-specific differences in sleep markers that may explain higher insomnia prevalence in females.

This study examines how habitual light exposure-related behaviors affect sleep timing and complaints in a large international sample, finding that outdoor time and device use in bed have significant impacts.

This paper reviews and meta-analyzes studies on sex differences in sleep spindles and slow wave activity in adults with and without insomnia, finding sex-based variations in spindle density and power but limited interaction effects.

This study shows that whole-night gentle rocking improves sleep quality and efficiency in individuals with insomnia complaints.

The study finds no seasonal variation in fatigue, sleepiness, or insomnia symptoms, suggesting spring fatigue is a cultural phenomenon rather than a biological syndrome.

This study uses machine learning on UK Biobank data to predict sleep health traits from brain imaging, finding limited predictive power despite extensive model optimization.

This study tests the feasibility of delivering down-phase targeted auditory stimulation during sleep at home over seven nights, finding it technically viable and showing reduced slow-wave activity in early sleep cycles.

This pilot study found that listening to personalized sound sequences derived from individual slow-wave brain activity improved sleep quality and quantity in adults with insomnia.

The paper analyzes sleep data from 1527 pediatric PSGs across five sites to study neurodevelopmental disorders, identifying sleep architecture disruptions in Down Syndrome and developing a sleep stager and brain age prediction model.

This study links self-reported sleep quality to subcortical morphometry, finding smaller shape measures in the caudate, putamen, and pallidum correlate with worse sleep quality, independent of demographic and biometric factors.

The paper examines how sleep quality moderates the relationship between reinforcement sensitivity and brain connectivity in healthy young adults, linking these factors to emotional health.

The paper identifies sleep-brain dimensions and biotypes in adolescents using device-based sleep data and imaging, linking them to cognitive and academic outcomes.

This study performs genome-wide association analysis on composite sleep health scores, identifying 28 novel loci and confirming 341 previously reported loci, with insights into genetic mechanisms and pathways.

The paper identifies age- and sex-related differences in sleep patterns using UK Biobank data and links sleep duration to self-reported depression and anhedonia.

This paper improves sleep stage prediction from wearable data by combining topological data analysis and mathematical modeling, achieving better accuracy in REM and NREM classification.

The paper identifies distinct structural brain connectivity deviations in insomnia subtypes using MRI data from multiple studies.

This study examines the relationship between cortical gyrification and sleep patterns in adolescents and young adults, identifying both stable and age-specific associations.

The paper investigates the effects of short sleep on brain structure and cognitive function, finding that short sleepers without daytime tiredness have larger brain volumes but slightly lower cognitive scores.

This study finds that poorer sleep health in healthy adults is linked to altered brain activation during cognitive control tasks, with stronger fronto-parietal and subcortical responses.

This study examines how sleep quality affects biological aging and its interaction with air pollution using UK Biobank data, finding sleep improves aging outcomes and mitigates pollution effects.

This study examines the relationship between sleep quality and brain ageing using neuroimaging data, finding that poor sleep is associated with accelerated brain ageing.

This study examines the long-term effects of a flexible school start time system on teenage sleep and psychological outcomes over one year, finding sustained sleep gains and gender-specific differences.

DPSleep infers sleep metrics from accelerometer data and links them to other variables, showing actigraphy-based sleep duration correlates with self-reported quality.

This study evaluates sleep disturbances in children with Rett, Angelman, and Prader-Willi syndromes compared to typically developing controls, identifying common sleep issues and their associations.

This study examines how sleep patterns relate to gray matter structure across adolescence, finding both stable and developmentally-specific associations in different brain regions.

The paper validates the Munich Actimetry Sleep Detection Algorithm (MASDA) for estimating sleep-wake patterns from activity recordings, showing good performance in field studies but lower specificity in polysomnography.

The paper identifies five sleep composites through PCA of infant sleep variables and shows their dynamic changes and associations with development.

This study finds genetic links between cannabis use and sleep deficits, including eveningness chronotype and insomnia, using LDSC and polygenic risk scores.

This study uses Mendelian Randomization to investigate causal relationships between insomnia and substance use, finding unidirectional and bidirectional effects.
