New Mechanism For Anxiety Disorders Revealed By Mystery GeneA novel mechanism for anxiety behaviors, including a previously unrecognized inhibitory brain signal, may inspire new strategies for treating psychiatric disorders, University of Chicago researchers report. By testing the controversial role of a gene called Glo1 in anxiety, scientists uncovered a new inhibitory factor in the brain: the metabolic by-product methylglyoxal...
Sleepwalking More Prevalent Among US Adults Than Previously SuspectedWhat goes bump in the night? In many U.S. households: people. That's according to new Stanford University School of Medicine research, which found that about 3.6 percent of U.S. adults - or upward of 8.4 million - are prone to sleepwalking. The work also showed an association between nocturnal wanderings and certain psychiatric disorders, such as depression and anxiety...
Hazardous To Health - Social Jet LagSocial jetlag - a syndrome related to the mismatch between the body's internal clock and the realities of our daily schedules - does more than make us sleepy. It is also contributing to the growing tide of obesity, according to a large-scale epidemiological study reported online in Current Biology, a Cell Press publication...
New Research Explains How Proper Sleep Is Important For Healthy WeightIf you're counting calories to lose weight, that may be only part of the weight loss equation says a new research report published online in The FASEB Journal. In the report, French scientists show that impairments to a gene known to be responsible for our internal body clocks, called "Rev-Erb alpha," leads to excessive weight gain and related health problems...
Headphones In Intensive Care Unit Help Patients' Confusion And Sleep Patterns Patients in an intensive care unit (ICU) often become confused or delirious soon after, or within a few days of admittance to the ICU. New research published in BioMed Central's open access journal Critical Care, shows that use of earplugs can result in better sleep (as reported by the patients), lower the incidence of confusion, and delay the onset of cognitive disturbances...
Fatigue May Impact Surgeons' Ability To Deal With The UnexpectedSleep-deprived surgeons can perform a previously learned task or learn a new task as well as surgeons who are rested, according to Penn State College of Medicine researchers. However, in sleep-deprived surgeons, the brain must work harder, which could lead to problems during unexpected events...
Plenty Of Sleep Helps Keep You SlimThe more we sleep the less our genes determine how much we weigh, while the less we sleep the more our genes impact - in other words, less sleep can contribute to people putting on the pounds, while plenty of sleep can help us stay slim, researchers from University of Washington Medicine Sleep Center in Seattle reported in the journal Sleep...
Insufficient Sleep Affects 30% Of US WorkersThe US Centers for Disease Control and Prevention (CDC) reports that 30% of the nation's workers are sleeping under 6 hours a day, which is less than the 7 to 9 hours that the National Sleep Foundation recommends for healthy adults. To assess the prevalence of insufficient sleep among US workers, the CDC analyzed data from the 2010 National Health Interview Survey (NHIS)...
Sleep Deprivation And Pilot PerformanceNight-time departures, early morning arrivals, and adjusting to several time zones in a matter of days can rattle circadian rhythms, compromise attention and challenge vigilance. And yet, these are the very conditions many pilots face as they contend with a technically challenging job in which potentially hundreds of lives are at stake...
Circadian Rhythm Disturbances Lead To Brain Cell Changes, May Cause Sleep Troubles In AgingOlder animals show cellular changes in the brain "clock" that sets sleep and wakeful periods, according to new research in the April 25 issue of The Journal of Neuroscience. The findings may help explain why elderly people often experience trouble sleeping at night and are drowsy during the day. Like humans, mice experience shifts in daily activities and sleep patterns as they age...
Tinnitus Linked To Insomnia Researchers at Henry Ford Hospital in Detroit have found a significant association between the severity of perceived tinnitus symptoms and insomnia. According to the researchers, over 36 million people experience tinnitus - chronic ringing, buzzing, hissing or clicking in the head and ears...
