A recent literature review and formal classification of sleep-related disorders associated with abnormal sexual behaviors and experiences have been published. These disorders, referred to as 'sleepsex' or 'sexsomnia', can cause disturbing and embarrassing symptoms, and may lead to delays in seeking help due to fear of judgment.
A recent study published in the SLEEP journal found that patients with severe obstructive sleep apnea (OSA) who used continuous positive airway pressure (CPAP) for longer periods at night experienced improved daytime functioning and reduced sleepiness. The study, conducted by Dr. Terri E. Weaver, suggests that a greater percentage of p...
Patients with stage four cancer have less quality sleep, which is linked to functional performance, mental health, and pain status. Poor sleep quality can be a critical factor in cancer treatment, highlighting the need for effective symptom management.
A new study by Ronald R. Grunstein found that judicial sleepiness is viewed unfavorably by the media, society, and the judicial system as a whole. Experts recommend regulatory processes to ensure the fitness for duty of judges and maintain confidence in the judicial process.
A study published in SLEEP found that sleep deprivation can adversely affect decision-making at a gambling table by elevating the expectation of gains and making light of losses. Brain imaging revealed selectively more active anticipation of reward in the nucleus accumbens, while attenuated response to losses in the insula.
A study by Roseanna Armitage found that chronic fatigue syndrome (CFS) is associated with reduced slow wave sleep and impaired sleep drive, even after a regular night's sleep. After a four-hour sleep delay, CFS individuals exhibited significantly less slow wave activity than healthy twins.
Researchers found that BiP levels increase after prolonged wakefulness and decline during recovery sleep, affecting the need for additional rest. The study suggests that protective mechanisms against cellular stress may be attenuated after sleep deprivation, requiring animals to sleep more to recover.
A study published by the American Academy of Sleep Medicine found that men who consume more alcohol have a higher risk of sleep-related breathing disorders. For each additional drink per day, the risk increases by 25%. The study suggests that men should avoid drinking before bedtime to minimize the risk.
A study published in JCSM found that 'night owls' experience more sleep/wake irregularities and waking distress due to insomnia. Insomnia affects 30% of adults, leading to serious health problems like depression, obesity, and cardiovascular disease.
A recent study published in the journal SLEEP found that healthy older men who get less nighttime sleep have lower morning testosterone levels. The study, conducted by Plamen Penev, MD, PhD, used polysomnography and wrist activity monitoring to measure sleep duration and its impact on testosterone levels.
A new study published in the journal Sleep found that sleep disturbance increases spontaneous pain in women. The study, conducted by Michael T. Smith and colleagues, used polysomnography to assess 32 healthy females and found that fragmented sleep profiles led to impaired natural pain control mechanisms.
Actigraphy is a reliable tool for evaluating sleep disorders, including advanced sleep phase syndrome, delayed sleep phase syndrome, and shift work disorder. It also helps characterize circadian rhythms and sleep patterns in patients with insomnia and hypersomnia.
A study published in SLEEP finds that obstructive sleep apnea is associated with an increased risk of cardiovascular disease, including systemic hypertension and heart failure. The study attributes this link to the physiologic effects of OSA on the body.
A study published in SLEEP found that sleep deprivation significantly affects the ability to integrate emotion and cognition for guiding moral judgments. Continuous wakefulness has a particularly debilitating effect on judgment and decision-making processes.
A recent study published in the journal SLEEP found that treating insomnia is far less costly than ignoring it, with costs ranging from $924 to $1,143 for six months prior to treatment. The study suggests that addressing insomnia can lead to significant cost savings for individuals and employers.
A new study published in the journal SLEEP found that sleepy driver near-misses may be dangerous precursors to actual accidents. The study analyzed 35,217 individuals and reported that near-miss accidents associated with sleepiness were common, occurring in 18.3% of the sample.
A study published in the Journal of Clinical Sleep Medicine finds that adolescents with sleep disturbances are more likely to receive bad grades, experiencing symptoms such as restless legs, difficulty concentrating, and snoring. Parents and teens can improve school performance by following recommended sleep habits.
A study by Chiara Cirelli and colleagues shows that the quality and intensity of wakefulness affect slow-wave activity (SWA) during subsequent sleep. High exploratory activity during wakefulness leads to increased brain-derived neurotrophic factor (BDNF) expression, which in turn affects SWA.
A new study published in the journal Sleep reveals that parasomnias are common and frequent in children. Pediatricians should actively involve parents in identifying symptoms and taking an active approach to helping their child overcome a sleep disorder. Home videos and sleep diaries can be useful tools for classifying parasomnias.
A study published in the SLEEP journal found that brain areas hyperactivated during cataplexy in a narcoleptic patient resemble those active during normal REM sleep, but without other characteristic features. This discovery may help explain how narcolepsy's cataplexy symptom occurs.
A comprehensive review published in the journal SLEEP found that environmental exposures before the age of onset in genetically susceptible individuals may contribute to the development of narcolepsy. The study suggests intensifying the search for these exposures and focusing on the first two decades of life to prevent the disease.
A study published in SLEEP found that sleep disturbances are prevalent among individuals who have attempted suicide, with 89% reporting some form of disturbance. Nightmares were particularly common and associated with a five-fold increase in suicidal risk.
A study published in SLEEP found that sleep-disturbed children are more severely depressed and have more depressive symptoms. The research also showed that having both insomnia and hypersomnia leads to a longer history of illness and more severe depression than either condition alone.
Obstructive sleep apnea (OSA) is associated with decreased cardiac function, leading to increased daytime sleepiness. A behavioral-educational intervention improved nighttime sleep for new mothers and their babies, resulting in better overall sleep quality.
Psychological and behavioral therapies are considered an effective treatment for insomnia, producing reliable changes in several sleep parameters. The studies found that treatments such as cognitive behavioral therapy and relaxation conditions were effective for primary insomnia, with benefits well sustained over time.
Behavioral therapies produce reliable changes in bedtime problems and night wakings in infants and children, with 82% of children benefiting from treatment. For women with obstructive sleep apnea (OSA), early diagnosis and treatment can reduce healthcare costs and improve sleep quality.
A new study published in JCSM found that brief behavioral treatment for insomnia (BBTI) significantly improves sleep quality and daytime symptoms of anxiety and depression in older adults. The study showed a 71% favorable response rate among BBTI participants, compared to 39% in the control group.
