Patients with sleep apnea who have short interruptions in breathing while they sleep are at higher risk for death than those with longer interruptions, according to a study published in the American Journal of Respiratory and Critical Care Medicine. The finding could help doctors better prevent long-term mortality associated with obstructive sleep apnea.
How long a person with obstructive sleep apnea (OSA) stops breathing may be a better predictor of mortality risk from OSA than the number of times they stop breathing, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
In a study of 15 patients affected by major depressive disorder and complaining of insomnia, initiating treatment with vortioxetine for their depressive symptoms led to significant improvements in subjective sleep quality and daytime sleepiness.
After studying the sleep habits of children from ages five to nine, researchers found that when mothers reported less flexibility in their work schedules, their children got less sleep. When they gained flexibility in their work schedules, their children slept more.
Lack of sleep during adolescence and early adulthood accelerates Alzheimer's disease (AD)-related tau pathology, finds a study of male and female mice published in JNeurosci. These results support the importance of establishing healthy sleep habits in early adult life to help stave off progression of neurodegenerative diseases.
UC San Francisco researchers, in collaboration with the unique Brazilian Biobank for Aging Studies (BBAS) at the University of São Paulo, have shown that the earliest stages of the brain degeneration associated with Alzheimer's disease (AD) are linked to neuropsychiatric symptoms including anxiety, depression, loss of appetite, and sleep disturbances.
Researchers from the CNRS, Claude Bernard Lyon 1 University, and Muséum National d'Histoire Naturelle have confirmed that lizards exhibit two sleep states, just like humans, other mammals, and birds. They corroborated the conclusions of a 2016 study on the bearded dragon and conducted the same sleep investigation on another lizard, the Argentine tegu. Their findings nevertheless point out differences between species, which raises new questions about the origin of sleep states.
Preliminary results from the world's largest sleep study have shown that people who sleep on average between 7 to 8 hours per night performed better cognitively than those who slept less, or more, than this amount. Neuroscientists from Western University's renowned Brain and Mind Institute released their findings today in the high-impact journal, SLEEP.
Identical brain mechanisms are responsible for triggering memory in both sleep and wakefulness, new research at the University of Birmingham has shown.
Clifford B. Saper, M.D., Ph.D., Chairman of the Department of Neurology at Beth Israel Deaconess Medical Center (BIDMC), and colleagues demonstrate in mice that that specific brain cells -- located in a region of the hypothalamus called the ventrolateral preoptic nucleus (VLPO) -- are in fact essential to normal sleep.
