Sleep EEG foundation models reveal within-stage microstructure that improves health screening beyond traditional stages For decades, sleep medicine has relied on a five-stage system to summarize an entire night of brain activity: wake, N1, N2, N3 (deep sleep), and REM. These stages are the language clinicians use to diagnose sleep disorders, assess sleep quality, and […]

Sleep deprivation damages every organ system, from brain to gut, comprehensive review finds Sleep deprivation is not merely a cause of daytime drowsiness. It is a systemic assault on the body that disrupts the nervous, cardiovascular, respiratory, digestive, immune, and endocrine systems simultaneously, according to a comprehensive review published in Frontiers in Neurology. The review, […]

We have known for years that poor sleep and Alzheimer’s disease travel together. The question is whether they are passengers or drivers of each other. A new study published in Frontiers in Aging Neuroscience adds a molecular layer to that puzzle, identifying two genes, FLOT1 and EEF1D, that may sit at the intersection of sleep […]

Pediatric Hypnotic Prescribing in Japan: A Decade of Change Before and After COVID-19 Lead Sleep medication use among children and adolescents in Japan more than doubled over the past decade, with a significant acceleration following the COVID-19 pandemic, according to a large observational study published in Sleep Medicine.

A disrupted circadian rhythm does more than leave you groggy — it may also threaten your sight. A large retrospective study published as a preprint on Research Square reports that people diagnosed with circadian rhythm sleep disorder (CRSD) develop open-angle glaucoma at roughly three times the rate of matched controls. Among those who took melatonin, […]

Lead We all lie awake from time to time, turning worries over in our minds. But what if the deepest fear of all — the fear of death itself — is the thing keeping us from restful sleep? New research published in Death Studies suggests just that: death anxiety is a significant predictor of insomnia, […]

Lead For decades, scientists believed that an animal’s circadian clock is strictly a slave to its environment: light hits the eye, signals travel to the brain, and the clock ticks in response. A new study published July 2 in Science turns that assumption on its head. Researchers at the University of Muenster have shown that […]

Restless legs syndrome is one of those conditions that sounds almost trivial until you have lived through it. The irresistible urge to move the legs, usually worse in the evening and at night, can delay sleep onset by an hour or more and fragment whatever rest does come. For the millions of people who manage […]

Dr. AI says you have sleep apnea: measuring the accuracy of patient-facing AI in sleep medicine You type “Do I have sleep apnea?” into ChatGPT and get back a detailed, confident, doctor-sounding answer in seconds. It feels like getting a second opinion without waiting months for a sleep study. But is that answer actually correct? […]
