Researchers from Columbia University Medical Center tested a method to reduce the adverse effects of evening ambient light exposure, while still allowing use of blue light-emitting devices.
Nearly 6 million Americans have bipolar disorder, and most have probably wondered why. After more than a decade of studying over 1,100 of them in-depth, a team of scientists has an answer -- or rather, seven answers.
Like swinging a tennis racket during a ball toss to serve an ace, slow and speedy brainwaves during deep sleep must sync up at exactly the right moment to hit the save button on new memories, according to new UC Berkeley research.
Scientists have identified differences in a group of genes they say might help explain why some people need a lot more sleep -- and others less -- than most. The study, conducted using fruit fly populations bred to model natural variations in human sleep patterns, provides new clues to how genes for sleep duration are linked to a wide variety of biological processes.
Researchers from Aarhus University have discovered that patients with the RBD sleep behavior disorder lack dopamine and have a form of inflammation of the brain. This means that they are at risk of developing Parkinson's disease or dementia when they grow older.
A single dose of lithium chloride, a drug used to treat bipolar disease and aggression, blocks the sleep disturbances, memory loss, and learning problems tied to fetal alcohol syndrome, new experiments in mice show.
When we sleep, our organism goes through different phases of sleep, however the brain remains interconnected during non-REM sleep, which was thought not to happen. The finding by a European team of researchers has also made it possible to analyse the scientific basis of consciousness, an increasingly important field of neuroscience.
A later school start time could mean teens are more likely to get adequate amounts of sleep, according to Penn State researchers.
A synthetic cannabis-like drug in a pill reduced apnea and daytime sleepiness in the first large multi-site study of a drug for apnea. The drug targets the brain in a new treatment strategy. There is currently no drug treatment for sleep apnea, a sleep breathing disorder affecting about 30 million individuals in the US. Untreated apnea raises the risk of heart disease, diabetes, sleepiness, cognitive impairment and a motor vehicle accident.
In a Journal of Advanced Nursing study, female gender and personal burnout were linked with impaired sleep quality among nurses.
