Recent studies have established that the orexin system is a critical regulator of sleep/wake states. Deficiency of orexin signaling results in the sleep disorder narcolepsy-cataplexy in humans, dogs, and rodents. These findings have brought about the possibility of novel therapies for sleep disorders including narcolepsy-cataplexy. Furthermore, accumulating evidence has indicated that the orexi...
introduction: information on the sleepiness and sleep quality is limited for asians. this study was conducted to determine the prevalence of sleepiness and sleep quality among the adult population in iran. materials and methods: this is a descriptive and explorative design study in which 1100 participants randomly selected from the kerman city population in south –east of iran. using two questi...
OBJECTIVES One of the hypothesized causes of the breakdown in sleep-wake consolidation often occurring in individuals with Alzheimer disease (AD) is the dysfunction of the circadian clock. The goal of this study is to report indices of sleep-wake function collected from individuals with AD in relation to relevant polymorphisms in circadian clock-related genes. DESIGN One week of ad libitum am...
BACKGROUND The prevalence of sleep disorders increases with age. Sleep disorders may have serious health implications and may be related to serious underlying diseases. Many older people use hypnotics, like benzodiazepines, although these medications have serious side effects and often lead to habituation. Acetaminophen is one of the most frequently used off-label drugs for sleep disorders, alt...
STUDY OBJECTIVES To assess the ability of repeated daily oral ramelteon to facilitate re-entrainment of human circadian rhythms after an imposed phase advance of the sleep-wake cycle. METHODS A total of 75 healthy adult volunteers aged 18-45 years remained in a sleep laboratory for 6 days and 5 nights; a 5-h phase advance in their sleep-wake cycle was imposed under dim-light conditions. Oral ...
Despite the predominance of sleep in early infancy, developmental science has yet to play a major role in shaping concepts and theories about sleep and its associated ultradian and circadian rhythms. Here we argue that developmental analyses help us to elucidate the relative contributions of the brainstem and forebrain to sleep-wake control and to dissect the neural components of sleep-wake rhy...
Schizophrenia is a psychiatric disorder that includes symptoms such as hallucinations, disordered thoughts, disorganized or catatonic behaviour, cognitive dysfunction and sleep-wake disturbance. In addition to these symptoms, cardiometabolic dysfunction is common in patients with schizophrenia. While previously it has been thought that cardiometabolic symptoms in patients with schizophrenia wer...
