Computer analysis of oxygen levels in the blood during sleep could – by itself – provide an easy, relatively inexpensive and sufficiently reliable way to determine which children who snore habitually could benefit from a diagnosis and treatment for obstructive sleep apnea.
Scientists exploring the brain for answers to certain sleep disorders may have been looking in the wrong place.
Matthew S. Kayser, MD, PhD, an assistant professor of Psychiatry and Neuroscience at Penn Medicine, has been awarded a 2017 Clinical Scientist Development Award from the Doris Duke Charitable Foundation (DDCF).
A lack of variation in the stress hormone cortisol from morning to evening is tied to a wide range of negative health conditions, including inflammation and immune system dysfunction, new Northwestern University research suggests. In the first comprehensive review of the relationship between daily cortisol fluctuations and health, researchers at the School of Education and Social Policy combined data from 80 different studies to show that while cortisol levels matter, a lack of variation from morning to evening may be even more telling.
People who carry a genetic susceptibility to Alzheimer’s disease appear to be at greater risk of diminished cognition from sleep-disordered breathing than those without the susceptibility, according to new research published online, ahead of print in the Annals of the American Thoracic Society.
More than a third of Americans don’t get enough sleep, and growing evidence suggests it’s not only taking a toll on their physical health through heart disease, diabetes, stroke, and/or other conditions, but hurting their mental health as well.
Researchers from UNLV, Duke University, and the University of Toronto, Mississauga, have found that mismatched sleep schedules and restless nights may be an evolutionary leftover from a time many, many years ago, when a lion lurking in the shadows might try to eat you at 2 a.m.
Research from Washington University School of Medicine in St. Louis, Radboud University Medical Centre in the Netherlands, and Stanford University shows that disrupting just one night of sleep in healthy, middle-aged adults causes an increase in a brain protein associated with Alzheimer’s disease. Further, a week of poor sleep leads to an increase in another brain protein that has been linked to brain damage in Alzheimer’s and other neurological diseases.
Having a good reason to get out of bed in the morning means you are more likely to sleep better at night with less sleep apnea and restless leg syndrome, reports a new Northwestern Medicine and Rush University Medical Center study based on older adults.This is the first study to show having a purpose in life specifically results in fewer sleep disturbances and improved sleep quality and over a long period of time.
Poor sleep may be a sign that people who are otherwise healthy may be more at risk of developing Alzheimer’s disease later in life than people who do not have sleep problems, according to a study published in the July 5, 2017, online issue of Neurology®, the medical journal of the American Academy of Neurology. Researchers have found a link between sleep disturbances and biological markers for Alzheimer’s disease found in the spinal fluid.
Research led by the University of Birmingham has discovered that patients who suffer from both Type 2 diabetes and obstructive sleep apnoea are at greater risk of developing a condition that leads to blindness within an average period of less than four years.
A Fred Hutchinson Cancer Research Center study, led by epidemiologist Dr. Parveen Bhatti, found that night shift work is associated with reduced ability to repair DNA lesions. Over time, DNA damage that is not repaired will cause mutations that can lead to cancer.
In the fruit fly, social isolation leads to sleep loss, which in turn leads to cellular stress and the activation of a defense mechanism called the unfolded protein response.
A systematic review of zolpidem for noninsomnia neurological disorders, including movement disorders and disorders of consciousness, finds reason for additional research.
A lack of sleep doesn’t just leave you cranky and spoiling for a fight. Researchers at The Ohio State University Institute for Behavioral Medicine Research say it also puts you at risk for stress-related inflammation.
The good news about flat head syndrome is that it doesn’t have consequences beyond cosmetics, and it can often be improved – if it doesn’t resolve on its own.
About 20 percent of children develop persistent pain after surgery, and a new study published in The Journal of Pain showed that poorer night-time sleep quality was significantly associated with greater next-day pain intensity over four months after surgery.
Stress during the workday can lead to overeating and unhealthy food choices at dinnertime, but there could be a buffer to this harmful pattern.
A late bedtime is associated with lower perceived control of obsessive thoughts, according to new research from Binghamton University, State University of New York.
People who suffer from insomnia are three times more likely to report thoughts of suicide and death during the past 30 days than those without the condition, reports a new meta-analysis from researchers at the Perelman School of Medicine at the University of Pennsylvania. The study is the first to control for depression and anxiety and evaluate in-depth the relationship between the broadly defined terms of insomnia and suicidality to reveal trends that may inform future targeted treatment for some of the 32 million individuals struggling with insomnia.
An old pharmaceutical product may be a new treatment for obstructive sleep apnea, according to new research presented today by University of Illinois at Chicago and Northwestern University scientists at the SLEEP 2017 annual meeting in Boston.
Officers who work afternoons are twice as likely to be fatigued, which puts them at greater risk for accidents, errors and stress, according to results of UB-led study that won first place in national conference poster competition.
Ilene Rosen, MD, MSCE, an associate professor of Clinical Medicine at the Perelman School of Medicine at the University of Pennsylvania and program director of the Penn Sleep Fellowship, has been elected the 32nd president of the American Academy of Sleep Medicine (AASM) board of directors.

Room sharing between babies and mothers beyond the first four months is associated with less sleep for babies and unsafe sleeping practices, according to Penn State College of Medicine researchers.
New findings suggest eating late at night could be more dangerous than you think. Compared to eating earlier in the day, prolonged delayed eating can increase weight, insulin and cholesterol levels, and negatively affect fat metabolism, and hormonal markers implicated in heart disease, diabetes and other health problems, according to results from researchers at the Perelman School of Medicine at the University of Pennsylvania.
David F. Dinges, PhD, chief of the division of Sleep and Chronobiology, and director of the Unit for Experimental Psychiatry in the Perelman School of Medicine at the University of Pennsylvania, has received the Nathaniel Kleitman Distinguished Service Award from the American Academy of Sleep Medicine.
Preliminary data from a new study suggests that NBA players had worse personal statistics in games that followed a late-night tweet between 11 p.m. and 7 a.m.
Your long-awaited vacation is right around the corner. As the calendar days peel away and you compile your to-do checklist, the issue of jet lag looms if your getaway involves crossing multiple time zones. “Anyone who has ever suffered jet lag knows firsthand that our bodies are persistent in how they keep track of time,” says Dr. Alon Avidan, director of the UCLA Sleep Disorders Center. “During jet lag, a rapid shift in the light-dark cycle temporarily disrupts one’s normal sleep-wake pattern, and our bodies become desynchronized.”
UC San Diego study of U.S. data suggests a sleep-deprived planet by century’s end. Researchers show that unusually warm nights can harm human sleep and that the poor and elderly are most affected. Rising temperatures will make sleep loss more severe.
Pediatric severe obstructive sleep apnea (OSA) in the Washington, DC metropolitan area is most common among inner city African-American children from low income families, according to a new study presented at the 2017 American Thoracic Society International Conference. The researchers also found that these children were most likely to have a delayed diagnosis.
Obstructive sleep apnea (OSA) may increase the risk of developing atrial fibrillation (AF), according to new research presented at the ATS 2017 International Conference.
Women with obstructive sleep apnea (OSA) appear to be at greater risk for serious pregnancy complications, longer hospital stays and even admission to the ICU than mothers without the condition, according to a new study of more than 1.5 million pregnancies presented at the ATS 2017 International Conference.
African Americans with sleep apnea and insomnia are rarely diagnosed with either problem, even when the severity of the two sleep disorders are likely to affect their health, according to new research presented at the ATS 2017 International Conference.
High levels of air pollution over time may get in the way of a good night’s sleep, according to new research presented at the ATS 2017 International Conference. “Prior studies have shown that air pollution impacts heart health and affects breathing and lung function, but less is known about whether air pollution affects sleep,” said lead author Martha E. Billings, MD, MSc, assistant professor of medicine at the University of Washington. “We thought an effect was likely given that air pollution causes upper airway irritation, swelling and congestion, and may also affect the central nervous system and brain areas that control breathing patterns and sleep.”
Sleep is important, but if there is something more important or interesting to do—for example, taking care of a baby, finishing a grant proposal before a deadline, or reading a fascinating book—we may stay up late. Sleep in fruit flies is a lot like human sleep, and like humans, flies can keep themselves awake if there is something important to do. In research published on May 16th in eLife, researchers report discovery of neurons that allow male fruit flies to suppress sleep so they can court female flies.
The Wichita State University student innovation team “Out Cold” has won the Koch Innovation Challenge grand championship. “Out Cold” is a customizable pillow with air chambers that helps reduce sleep discomfort. Team members won an opportunity to represent WSU at the National Conference & Pitch Competition, hosted by The Collegiate Entrepreneurs’ Organization (CEO) this fall.
A Loyola Medicine study has found that two simulation techniques dramatically improved physicians' brain death diagnostic and communications skills. The techniques employ SimMan® 3G, a high-tech patient simulator (mannequin) and actors who simulate family members having a brain-death discussions.
Study shows that slow-moving meditation practice works just as well as talk therapy, and better than medication
New research from Beth Israel Deaconess Medical Center (BIDMC) and Boston Children’s Hospital shows that chronic sleep loss increases pain sensitivity. It suggests that chronic pain sufferers can get relief by getting more sleep, or, short of that, taking medications to promote wakefulness such as caffeine. Both approaches performed better than standard analgesics in a rigorous study in mice, described in the May 8, 2017 issue of Nature Medicine.
A team of University of Iowa researches has discovered a new connection between two regions of the brain that may help explain how motor skills develop. Working with infant rats, the scientists found that the hippocampus and the red nucleus, part of the brain stem, synchronize during REM sleep. Findings published in the journal Current Biology.
Knowing the signs of becoming drowsy behind the wheel, many of which are similar to distracted and drunk driving, could potentially be lifesaving.
The key to improving confidence among parents of ill or premature infants may lie in simulated care, found new research led by University at Buffalo nursing researcher Deborah Raines.
Skimping on sleep, followed by “catch-up” days with long snoozes, is tied to worse cognition — both in attention and creativity — in young adults, in particular those tackling major projects, Baylor University researchers have found.
Research from the University of Georgia shows that 10 minutes of walking up and down stairs was more likely to make participants feel energized than ingesting 50 milligrams of caffeine.
Researchers at the University of Illinois at Chicago College of Medicine have found that an area of the brain, the dorsal anterior cingulate cortex, may have to work harder to modify negative emotional responses in people with poor sleep who have depression or anxiety.
Researchers from the Peter O’Donnell Jr. Brain Institute will participate in a national study to determine whether medical devices used in the home can diagnose sleep apnea that often develops after traumatic brain injuries (TBI).
Parents know that co-sleeping is considered a no-no, but many still allow their children to crawl into bed with them at night. Doctors generally discourage co-sleeping, but an Iowa State professor says it is a phenomenon that extends well beyond the infant and toddler years.
People with type 2 diabetes have poorer control over their blood glucose levels when they work the night shift compared with those who work in the daytime or are unemployed, a new study finds. The study results, to be presented Monday at the Endocrine Society’s 99th annual meeting in Orlando, Fla., showed that poor long-term glycemic, or blood sugar, control, was independent of what workers ate or any sleep problems they had.
Healthcare providers can use a decision-tree tool to screen women who have gestational diabetes (GDM) for obstructive sleep apnea (OSA), new research from Thailand reports. The results of the study will be presented in a poster Saturday, April 1, at ENDO 2017, the annual scientific meeting of the Endocrine Society, in Orlando, Fla.
People with type 2 diabetes who are “night owls” and prefer the evening for activity report having more symptoms of depression than those who are early to bed and early to rise, regardless of the quality of their sleep, a new study finds. Study results are being presented Saturday at the Endocrine Society’s 99th annual meeting in Orlando, Fla.
