Using Twitter to monitor the attitudes of 2.4 million people in 84 countries, Cornell University researchers found that people all over the world awaken in a good mood – but globally that cheer soon deteriorates once the workday progresses.
By tracking Twitter tweets over two-years, researchers determined that work, sleep and the amount of daylight all play a role in shaping cyclical emotions such as enthusiasm, delight, alertness, distress, fear and anger.
A new study published by Cell Press in the American Journal of Human Genetics uncovers a mutation that causes narcolepsy in a large family affected by the disorder. The research sheds new light on the genetics of inherited narcolepsy and provides intriguing insight into other complex neuropsychiatric disorders.
Although most cases of narcolepsy are thought to be caused by complex mechanisms, a small percentage of cases are associated with unidentified inherited mutations.
University of Utah engineers who built wireless networks that see through walls now are aiming the technology at a new goal: noninvasively measuring the breathing of surgery patients, adults with sleep apnea and babies at risk of sudden infant death syndrome (SIDS).
Study authors estimates it will be five years until such a product is on the market. They say a network of wireless transceivers around a bed can measure breathing rates and alert someone if breathing stops without any tubes or wires connected to the patient.
Elderly women who suffer from sleep apnea -- characterized by disrupted breathing and sleep and a reduction in the intake of oxygen -- are about twice as likely to develop dementia in the next five years as those without the condition, according to a multi-center study led by researchers from the University of California, San Francisco.
A new study suggests that men with erectile dysfunction (ED) should be screened for obstructive sleep apnea (OSA). After adjusting for age and other health conditions, patients with ED were more than twice as likely to have sleep apnea than their normal counterparts.
Staying up late, sleeping in every day and eating after 8:00 pm may be risk factors in weight gain. A recent study from Northwestern Medicine found that late sleepers consumed 248 more calories a day, mainly at dinner and later in the evening. They ate half as many fruits and vegetables, twice the fast food and drank more full-calorie sodas than those with earlier sleep times.
Washington, DC, April 28, 2011-- Americans are justifiably concerned by the recent spate of incidents involving air traffic controllers who fell asleep on duty. But now that the FAA/DoT has outlined the steps it intends to take to address this problem – minor tweaking of the controllers’ work/rest schedules combined with a threat of stricter disciplinary action against offending controllers in the future – the public’s response ought to escalate from concern to alarm.
A new study of more than 350 families found that marital instability when infants are 9 months predicted difficulties falling asleep and staying asleep when they were 18 months old. This finding held true even after considering factors like children's temperaments, parents' anxiety levels, and birth order. However, the researchers found that the inverse wasn't true—children's sleep problems did not predict marital instability.
The FDA recently approved a new drug to treat restless legs syndrome (RLS). Horizant Extended Release Tablets (gabapentin enacarbil), a once-daily treatment, is the third drug approved by the FDA to treat moderate-to-severe restless legs syndrome (RLS).
RLS is a neurological movement disorder that disrupts sleep. It is characterized by an irresistible urge to move due to tingly or uncomfortable sensations in your legs when you’re lying in bed. Epidemiological studies have shown that RLS affects between 7% and 10% of Americans.
More than 450 attended the National Sleep Foundation’s Sleep Health & Safety conference on March 17-18, 2011 at the JW Marriott in Washington, DC. Larry Culpepper, MD and Charles Czeisler, PhD, MD, co-chaired a dual track program for healthcare professionals and researchers.
