Functional data analysis of college students’ sleep patterns and their relationships with academic performance and social networks: A four-year longitudinal study College students who earn higher grades sleep nearly half an hour longer each night on average, and the size of that sleep advantage fluctuates dramatically across undergraduate years, according to a new longitudinal study […]

SleepConFormer: Single-Channel EEG Framework Achieves 91.7% Accuracy for Consciousness Assessment in DOC Patients A novel machine learning framework called SleepConFormer can distinguish patients in a minimally conscious state (MCS) from those with unresponsive wakefulness syndrome (UWS) with 91.7% accuracy using only a single electroencephalography (EEG) channel, according to a study published in IEEE Transactions on […]

Sleep deprivation and neuronal hyperexcitation share molecular fingerprints, large-scale transcriptomic analysis finds A systematic analysis of publicly available brain gene expression data has found that sleep deprivation produces a molecular fingerprint nearly indistinguishable from that of acute neuronal hyperexcitation. Researchers at Fujita Health University in Japan report that 73% of cross-model comparisons showed significant positive […]

Introducing Actigraphic Data Analyzer (ADA), an open source software for sleep/wake scoring and circadian rhythm analysis with graphical interface New open-source software makes advanced actigraphic analysis accessible to researchers without programming expertise. Researchers at the University of Warsaw and SWPS University have released Actigraphic Data Analyzer (ADA), a free and open-source Python package that brings […]

The Obstructive Sleep Apnea Mortality Paradox: Why a High-Risk Disorder Can Appear Protective in Short-Term Outcome Studies Lead Obstructive sleep apnea (OSA) is an established risk factor for hypertension, coronary artery disease, stroke, and increased long-term mortality. Yet a growing body of observational studies, particularly those drawing on administrative databases and intensive care unit cohorts, […]

Endothelial and Angiogenic Biomarkers in Obstructive Sleep Apnea: Longitudinal Associations With Continuous Positive Airway Pressure Lead. Does continuous positive airway pressure (CPAP) therapy meaningfully alter the vascular biology that drives cardiovascular risk in obstructive sleep apnea (OSA)? A new prospective cohort study published in Archivos de Bronconeumología provides the longest longitudinal data to date, tracking […]

A hierarchical cascade of sleep rhythms supports motor memory and is hijacked by epileptic spikes in human epilepsy ID: 42378289 PMID: 42378289 Lead Sleep is widely believed to help consolidate memories, but the precise neural machinery responsible has been difficult to observe directly in the human brain. A new intracranial EEG study in 19 patients […]

Impact of sleep duration on bone mineral density and osteoporosis risk: A systematic review and meta-analysis Lead For years, doctors have warned that skimping on sleep raises the risk of heart disease, diabetes, and cognitive decline. A new systematic review and meta-analysis now adds bone health to that list. The study, which pooled data from […]

A mattress sensor that reads your breathing can tell REM from NREM sleep Lead. A sensor placed under the mattress, requiring no wires, belts, or contact with the sleeper, can distinguish REM from NREM sleep with about 84% accuracy, according to a new study published in Frontiers in Digital Health. The research, led by Shaonan […]
