Twin study suggests genetic factors contribute to insomnia in adults
Sep 16, 2015
A new study of twins suggests that insomnia in adults is partially explained by genetic factors, and this heritability is higher in females than in males. The study provides some of the first formal evidence for sex differences in an adult sample.
Ramelteon may be useful for sleep problems after traumatic brain injury
Researchers found preliminary evidence for the effectiveness of ramelteon for the treatment of sleep disturbances after traumatic brain injury. Ramelteon increased the total time asleep and seemed to bring more consistency to sleep-wake cycles, reports the article e-published ahead of print in the Archives of Physical Medicine and Rehabilitation.
Could body posture during sleep affect how your brain clears waste?
Aug 03, 2015
Sleeping in the lateral, or side position, as compared to sleeping on one’s back or stomach, may more effectively remove brain waste and prove to be an important practice to help reduce the chances of developing Alzheimer, Parkinson, and other neurologic diseases, according to researchers at Stony Brook University.
Study finds brain chemicals that keep wakefulness in check
Jul 29, 2015
Mice that have GABA switched off become hyperactive and sleep for just 65% of their normal time. This discovery, published in the journal Neuron, could help researchers to develop new drugs that promote better sleep, or control hyperactivity in people with mania.

The research abstract was published recently in an online supplement of the journal Sleep and will be presented today at SLEEP 2015, the 29th annual meeting of the Associated Professional Sleep Societies LLC.
Despite abnormalities after concussion, sleep continues to aid memory and recall
Jun 05, 2015
After a concussion, a person can be left with disturbed sleep, memory deficits, and other cognitive problems for years, but a new study from the University of Massachusetts Amherst suggests that despite these abnormalities, sleep still helps them to overcome memory deficits, and the benefit is equivalent to that seen in individuals without a history of mild traumatic brain injury.
Impaired sleep linked to lower pain tolerance
May 01, 2015
People with insomnia and other sleep problems have increased sensitivity to pain, reports a study published in PAIN®. The new study is the first to link insomnia and impaired sleep to reduced pain tolerance in a large, general population sample.
Study draws connection between narcolepsy and influenza
Aug 22, 2011
The onset of narcolepsy appears to follow seasonal patterns of H1N1 and other upper airway infections, according to a new study of patients in China that was led by a Stanford University School of Medicine narcolepsy expert.
Patients in a minimally conscious state remain capable of dreaming during their sleep
Aug 17, 2011
An EEG study has revealed that the sleep of patients in a minimally conscious state has characteristics very close to that of normal sleep in a healthy subject. They show changes in “slow wave” activity in the front of the brain considered important for learning and neural plasticity, and produce NREM (non rapid eye movement) slow wave sleep and REM (rapid eye movement) sleep, which is the support for dream activity.
Sleep disordered breathing may increase risk of dementia in older women
Aug 10, 2011
Older women who have sleep-related breathing problems may be at greater risk of problems with mental function, including dementia, according to a new study in the August 10, 2011 issue of the Journal of the American Medical Association.
Nighttime-breathing machine effective treatment for sleep apnea
Aug 08, 2011
Among the treatments for obstructive sleep apnea, the effectiveness of the continuous positive airway pressure machine was backed by the strongest evidence, and a mouthpiece worn at night was also shown to be effective, according to a new report funded by HHS’ Agency for Healthcare Research and Quality.
Clinical study for insomnia uses new technology
Jun 30, 2011
Insomnia is the most prevalent sleep disorder, affecting up to 50 percent of the adult population in the United States on a weekly basis. The first ever, randomized, controlled clinical research study is using Brainwave Optimization™ to treat people with insomnia.
Potential genetic cause of REM sleep behavior disorder discovered, Parkinson disease implications
Jun 15, 2011
Researchers at the University of Toronto are the first to identify a potential cause for a severe sleep disorder--REM sleep behavior disorder--that has been closely linked to Parkinson disease and other neurodegenerative diseases.
The good life: good sleepers have better quality of life and less depression
Jun 14, 2011
Getting 6 to 9 hours of sleep per night is associated with higher ratings for quality of life and lower ratings for depression, suggests a research abstract that will be presented today in Minneapolis, Minnesota, at SLEEP 2011, the 25th Anniversary Meeting of the Associated Professional Sleep Societies.
Cooling the brain during sleep may be a natural and effective treatment for insomnia
Jun 13, 2011
People with primary insomnia may be able to find relief by wearing a cap that cools the brain during sleep, suggests a research abstract that will be presented today in Minneapolis, Minnesota, at SLEEP 2011, the 25th Anniversary Meeting of the Associated Professional Sleep Societies.
Researchers identify the roots of memory impairment resulting from sleep deprivation
May 18, 2011
From high-school students to surgeons, anyone who has pulled an all-nighter knows there is a price to be paid the next day: trouble focusing, a fuzzy memory, and other cognitive impairments. Now, researchers at Penn have found the part of the brain and the neurochemical basis for sleep deprivation's effects on memory.
Protein keeps sleep-deprived flies ready to learn
May 05, 2011
A protein that helps the brain develop early in life--NOTCH--can fight the mental fuzziness induced by sleep deprivation, according to researchers at Washington University School of Medicine in St Louis.
Adverse changes in sleep duration are associated with lower cognitive scores in middle-aged adults
May 03, 2011
A study in the May 1 issue of the journal SLEEP describes how women and men who begin sleeping more or less than 6 to 8 hours per night are subject to an accelerated cognitive decline.
From the beginning, the brain knows the difference between night and day
Apr 29, 2011
The brain is apparently programmed from birth to develop the ability to determine sunrise and sunset, new research on circadian rhythms at the University of Chicago shows.
Tired neurons caught nodding off in sleep-deprived rats
Apr 27, 2011
A new study in rats is shedding light on how sleep-deprived lifestyles might impair functioning without people realizing it. The more rats are sleep-deprived, the more some of their neurons take catnaps – with consequent declines in task performance. Even though the animals are awake and active, brainwave measures reveal that scattered groups of neurons in the thinking part of their brain, or cortex, are briefly falling asleep.
