Sleep

A new study of more than 2,100 Chinese middle school students reveals that the way academic stress affects mental health through sleep differs sharply by both educational stage and gender. The findings, published in Scientific Reports, suggest that sleep problems carry different psychological consequences for girls depending on whether they are in junior or senior […]

A new study from Chinese researchers shows that a simple set of eight clinical and laboratory markers, fed into a logistic regression model, can reliably predict which patients with metabolic dysfunction-associated steatotic liver disease (MASLD) are likely to also have obstructive sleep apnea (OSA). The finding could help clinicians identify high-risk MASLD patients who would […]

Lead. A new study using Riemannian geometry-based machine learning on high-density EEG recordings suggests that declarative odor cueing during sleep produces more structured spindle-band covariance patterns than non-declarative odor cueing, particularly over central brain regions. However, the effects were modest and did not survive correction for multiple comparisons, tempering the strength of the conclusions. Published […]

Lead. Sleep problems are among the most common health complaints during adolescence, affecting up to 40% of teenagers. The relationship between poor sleep and emotional disorders is well established but poorly understood at the neural level. Not every adolescent with insomnia develops depression or anxiety, and clinicians have lacked reliable biological markers to distinguish those […]

Lead. Getting a reliable sleep assessment usually means spending a night in a lab wired to dozens of electrodes. Polysomnography (PSG), the gold standard for sleep staging and apnea diagnosis, is cumbersome, expensive, and ill-suited for routine screening or at-home use. Now a large international team has published results for BCGNet, a deep learning model […]

Lead. Sleep is essential for recovery, yet critically ill children in the pediatric intensive care unit (PICU) may experience profound sleep disruption that goes unrecognized. A new observational study published in Acta Paediatrica provides the first comprehensive, age-adjusted comparison of sleep architecture in critically ill children versus non-critically ill controls, using full polysomnography. The findings […]

Lead. Sleep is increasingly recognized not as a passive rest state but as an active period of neural computation, during which the brain replays and consolidates memories through precisely timed oscillations. A new commentary in Epilepsy Currents by Jennifer N. Gelinas (University of California Irvine) asks whether we can harness this architecture therapeutically. Her piece, […]

Lead. Post-traumatic stress disorder remains one of the most challenging neuropsychiatric conditions to treat, particularly because its core symptoms, hyperarousal, nightmares, fear extinction deficits, and sleep disruption, feed into one another in a self-reinforcing loop that standard pharmacotherapy often fails to break. A scoping review published July 2 in Military Medicine (PMID: 42391109) now points […]

Lead. Researchers have shown that selectively disabling the circadian gene Clock in dopamine-producing neurons of the ventral tegmental area (VTA) is sufficient to alter sleep patterns, behavior, and the electrical properties of those neurons in mice. The study, published as a preprint on bioRxiv, provides some of the most direct evidence to date linking Clock […]
