Decreased nightly total sleep time, even within the normal range, is associated with an increased percentage of REM sleep during subsequent naps.   view more (2008-06-10)

People with Near Death Experiences Can Differ in Sleep-Wake Control
People who have had near death experiences often have different arousal systems controlling the sleep-wake states than people who have not had a near death experience.   view more (2006-04-11)

Less REM sleep associated with being overweight among children and teens
Children and teens who get less sleep, especially those who spend less time in rapid eye movement (REM) sleep, may be more likely to be overweight, according to a report in the August issue of Archives of General Psychiatry, one of the JAMA/Archives journals.   view more (2008-08-05)

Tobacco exposure in womb may slow arousal response and help explain increased cot death risk among babies of smokers
A slower arousal response, as a result of tobacco exposure in the womb, might explain the increased risk of cot death (SIDS) among babies of smokers, suggests research in the Archives of Disease in Childhood.   view more (2002-12-17)

Chronic fatigue syndrome impairs a person's slow wave activity during sleep
Chronic fatigue syndrome (CFS) has been associated with altered amounts of slow wave sleep, which could reflect reduced electroencephalograph (EEG) activity and impaired sleep regulation.   view more (2007-05-01)

Out-of-body experiences may be caused by arousal system disturbances in brain
Having an out-of-body experience may seem far-fetched to some, but for those with arousal system disturbances in their brains, it may not be a far off idea that they could sense they were really outside their own body watching themselves. In previous studies of more than 13,000 Europeans, almost 6 percent said they have had such an out-of-body... view more... (2007-03-06)

Sleep apnea occurring during REM sleep is significantly associated with type 2 diabetes
A multi-ethnic study in the June 15 issue of the Journal of Clinical Sleep Medicine reports that there is a statistically significant relationship between obstructive sleep apnea (OSA) episodes occurring during rapid eye movement (REM) sleep and type 2 diabetes.   view more (2009-06-16)

Naps with rapid eye movement sleep increase receptiveness to positive emotion
Naps with rapid eye movement (REM) sleep refresh the brain's empathetic sensitivity for evaluating human emotions by decreasing a negative bias and amplifying recognition of positive emotions.   view more (2009-06-10)

Children with Down Syndrome sleep poorly and have more fragmented sleep
Children with Down Syndrome sleep poorly, with more fragmented sleep and frequent awakenings compared to typically developing children, according to a research abstract that will be presented on Tuesday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).   view more (2008-06-10)

Type of anesthetic will improve sleeping medication, probe mysteries of the snooze
Researchers at the University of Alberta have discovered sleep patterns in a type of anesthesia that are the closest ever to a natural, non-groggy snooze.   view more (2008-04-17)

REM sleep behaviour disorder is an early marker of neurodegenerative diseases
The front page of the July 2006 issue of The Lancet Neurology, the journal with the highest international impact, contains a work that shows the relationship between disorders during REM sleep and future neurodegenerative pathologies.   view more (2006-06-29)

Alcohol increases sleep intensity in young women
While numerous studies have linked alcohol abuse to sleep disruption, especially in males, there has been little research on alcohol and its effects on sleep in females. Now, a new study shows that a moderate amount of alcohol, taken before bed, can impact the quality of sleep for young women.   view more (2006-08-22)

Alcoholism's effect on sleep persists during long periods of sobriety
A study in the Oct.1 issue of the journal Sleep shows that long-term alcoholism affects sleep even after long periods of abstinence, and the pattern of this effect is similar in both men and women.   view more (2009-10-01)

Link found between poor sleep quality and increased risk of death
Quality, in addition to quantity, is important for maintaining health, according to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.   view more (2009-06-10)

Baby's first dreams
After about seven months growing in the womb, a human fetus spends most of its time asleep. Its brain cycles back and forth between the frenzied activity of rapid eye movement (REM) sleep and the quiet resting state of non-REM sleep.   view more (2009-04-14)

REM sleep associated with overweight in children and adolescents
Short sleep time is associated with overweight in children and adolescents, a core aspect of which may be attributed to reduced REM sleep, according to a research abstract that will be presented on Thursday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).   view more (2008-06-12)

Sleep patterns in children and teenagers could indicate risk for depression, researcher finds
Sleep patterns can help predict which adolescents might be at greatest risk for developing depression, a researcher at UT Southwestern Medical Center has found in a five-year study.   view more (2009-08-13)

Abnormal sleep patterns appear common in children with Down syndrome
More than half of children with Down syndrome may have abnormal sleep patterns and obstructive sleep apnea syndrome, and parents may not be able to determine whether their children are among those with sleep difficulties.   view more (2006-04-18)

Resemblance between cataplexy during status cataplecticus, normal REM sleep
The first efforts to identify the neural structures and pathways underlying cataplexy during status cataplecticus in a narcoleptic patient, with the use of brain perfusion single photon emission computed tomography (SPECT), have led to the discovery that cataplexy during status cataplecticus, a case of prolonged cataplexy, partially resembles... view more...

Persons with narcolepsy with cataplexy have low levels of CSF hypocretin-1
Persons with narcolepsy with cataplexy have low levels of cerebrospinal fluid (CSF) hypocretin-1, a protein thought to help regulate sleep and wakefulness, according to a study published in the August 1st issue of the journal SLEEP.   view more (2007-08-01)
