Sleep

The relationship between poor sleep and Alzheimer’s disease is often described as a link, but a new review in Sleep Medicine argues it is more accurate to call it a vicious cycle. Sleep disruption accelerates Alzheimer’s pathology, and Alzheimer’s pathology in turn degrades sleep, creating a self-reinforcing loop driven […]

The diagnosis of Alzheimer’s disease has moved toward biological definitions based on cerebrospinal fluid (CSF) biomarkers and amyloid PET imaging. But lumbar punctures are invasive, and PET scans are expensive. A new study in GeroScience asks whether a simpler, cheaper, and non-invasive measure , the sleep EEG , can […]

Restless legs syndrome (RLS) affects an estimated 5 to 10 percent of adults, causing uncomfortable sensations in the legs and an irresistible urge to move them, particularly at night. Sleep fragmentation is the rule rather than the exception. The standard pharmacological approach relies on dopamine receptor agonists such as […]

Narcolepsy type 1 (NT1) is defined by the loss of orexin-producing neurons in the hypothalamus, leading to excessive daytime sleepiness, cataplexy, and fragmented nighttime sleep. A definitive diagnosis can be made by measuring orexin levels in cerebrospinal fluid, a test with high specificity. Yet in Australasia, this diagnostic tool […]

Primary dysmenorrhea affects a large proportion of young women, causing recurring menstrual pain that often disrupts sleep, limits physical activity, and reduces quality of life. Pain relievers are the standard approach, but non-pharmacological options are increasingly of interest. A new randomized controlled trial from Turkey examined whether a 12-week […]

— title: “Lifelong Running Preserves Circadian Health in Older Men, But Young Runners May Pay a Sleep Cost” post_status: draft post_author: 1 post_category: sleep — Kosice — It is well established that circadian rhythms weaken with age. Sleep becomes more fragmented, the daily rest-activity cycle loses its sharpness, and […]

— title: “Sleep Disturbances Raise Alzheimer’s Risk by 40% in 13-Million-Participant Meta-Analysis” post_status: draft post_author: 1 post_category: sleep — The link between poor sleep and Alzheimer’s disease has been studied extensively, but a persistent question has clouded the evidence: does sleep disruption actually cause neurodegeneration, or is it an […]

A Swiss population-based study combining subjective reports with overnight PSG reveals one-third of adults report insomnia symptoms, with women affected at nearly double the rate of men.

REM sleep reshapes semantic networks by combining remote concepts and reducing irrelevant associations, but restructuring alone is not enough for creative insight, a Paris Brain Institute study finds.

The Body’s Broken Clock: How Circadian Disruption May Drive Depression — and Why Timing-Based Treatments Are the Next Frontier More than 300 million people worldwide live with major depressive disorder, a condition the World Health Organization estimates affects 5.7% of adults globally. For decades, treatment has revolved around talk […]
