Active clinical trials for "Sleep Wake Disorders"

The study examines and illustrates the utility of utilizing actigraphic measurements to assess treatment response.

Cognitive dysfunction, either alone or as an element in the syndrome of delirium, is a common occurrence with an incidence as high as 75% in intensive care unit (ICU) patients and can independently result in serious consequences including higher mortality rate. Delirium develops through a complex interaction between the patient's baseline vulnerability (risk factors) and precipitating factors such as disruption of sleep that may occur during hospitalization. While sedative-hypnotic agents that are used to facilitate hypnosis and the management of mechanically ventilated patients converge on the neural substrate that mediate endogenous sleep, they do so at different juncture points depending on its molecular mechanism of hypnotic action. Hypnotic agents that modulate the GABAA receptor converge at the level of the hypothalamus while α2 adrenergic agonists converge on sleep pathways within the brainstem. This translational project seeks to determine whether sedation mediated by activation of α2 adrenoceptors (dexmedetomidine) is more like natural sleep than that provided by a sedative agent that modulates the GABAA receptor (propofol). The investigators will examine volunteers who will be monitored continuously by electroencephalography (EEG) and whole-brain functional connectivity by magnetoencephalography (MEG) during each of three sleep stages, namely, that induced by dexmedetomidine, propofol, or saline (natural sleep, control). The two drug-induced sleep regimens will be compared to natural sleep using EEG and brain connectivity by MEG

Lack of sleep and poor sleep quality in pregnant women are associated with maternal depression and cognitive-sensual irregularities. These irregularities were reported worsening women's life quality and even increasing suicide ideation. It is also associated with obstetrical complications such as fetal growth deficiency, preterm birth, prolonged labor, preeclampsia and increased abdominal delivery frequency.Vitamin D also may affect the sleep indirectly through the cases with nonspecific pains. It was reported that vitamin D levels are correlated with sleep disorders such as obstructive sleep apnea and restless legs syndrome. The primary purpose of this study is to examine sleep disorders and vitamin D levels in pregnant women, and also, secondarily, vitamin D - anxiety and sleep disorders - anxiety relations were assessed.

The aim of this study was to compare the depression and sleep disturbances of operated endometriosis patients before and after the operation. The main objective here is to provide data on how patients' psychological states and sleep patterns are affected by the symptoms of endometriosis and how these effects can be corrected. In this way, it is aimed to determine whether the patients have psychological support needs and to give the planned treatment due to endometriosis in the early period. As a secondary goal, it is planned to keep the patients in follow-up with their improved sleep and psychological conditions, and to improve their adherence to treatment and quality of life.

Subjects who consent to participate in the research will undergo a simultaneous recording of inlab PSG and WatchPAT200 for comparing the WatchPAT data to PSG at an altitude of 8500'.

The presence of protein in urine is a common laboratory finding in children. Although proteinuria is usually benign, it can be a marker of a serious underlying renal disease or systemic disorder. Microalbuminuria can be one of the first subclinical manifestations of endothelial dysfunction and is associated with low grade systemic inflammation. Multiple studies from the adult population suggest that microalbuminuria above the upper quartile is linked with increased risk of coronary heart disease and death even after adjustment for the presence of diabetes mellitus, obesity and hypertension. Obstructive sleep apnea (OSA) has been recognized as an independent risk factor for cardiovascular morbidity related to sympathetic nervous system overflow, metabolic dysregulation, inflammation and endothelial dysfunction secondary to repetitive hypoxia -reoxygenation events. Therefore, there is a need for further studies to investigate the association between OSA and microalbuminuria in children. Furthermore, no studies have thus far investigated the association between other sleep disorders such as periodic limb movement (PLMD) and microalbuminuria in children. Our hypothesis is that children with sleep disorders or short sleep duration have increased risk of proteinuria/microalbuminuria and that treatment and resolution of the sleep problem will be followed by improvement in proteinuria levels.

Sleep disorder is often a complaint from the older people. Prevalence of sleep disorder increases with aging and reaches between 20 to 45% of the people of 65 years old and more. Sleep physiologically changes with aging. Sleep can also be disturbed by other factors such as intercurrent or related chronic pathologies, environmental change (institutionalized, death of a spouse…), or some medical treatments. Regardless of interindividual variabilities, normative criteria have been defined by a meta-analysis: insomnia can be diagnosed if night wakings are more than 60min and/or if sleep latency is more than 30 minutes. Various studies have proved the major role of sleep on health and wellbeing. Sleep disorders have an impact on the quality of perception of health and on the quality of life of people and their spouse. According to the French High Health Authority recommendations, sleep diary and validated scales are the tools to use to investigate sleep disorders. Results from previous studies brought us to consider sleep complaint more specifically and adjust to the heterogeneous population of the investigator's hospital with a subjective approach. This work intends to offer a program of individualized advice to older patients with no cognitive impairment, or with a mild or moderate cognitive impairment, who complain about their sleep quality. Patients with a moderate cognitive impairment who have a caregiver at home can also join the study. The main objective of the study is to evaluate the impact of individualized care for sleep disorders on quality of sleep using the Pittsburgh Sleep Quality Index which validity was demonstrated among the elderly.

The current project is a safety and health intervention focused on sleep and fatigue among truck driver teams (pairs), where one driver sleeps in a moving vehicle while the other partner drives. This study is conducted within the Oregon Healthy Workforce Center (OHWC), a NIOSH Center of Excellence in Total Worker Health. We will evaluate engineering and behavioral interventions to improve sleep, reduce fatigue, and impact Total Worker Health. An enhanced cab intervention will alter whole body vibrations during driving and sleep periods, and includes a therapeutic mattress system and an active suspension seat. The enhanced cab will be evaluated alone and in combination with a behavioral sleep intervention adapted from our effective SHIFT (Safety &Health Involvement For Truckers) program. The interventions prioritize hazard reduction according to the hierarchy of controls, and will be evaluated with a randomized controlled design.

The aim of this study is to investigate the role of the circadian system in patients with neurologic sleep-wake disorders. Therefore, overnight sleep will be distributed over 30 hours into repetitive sleep-wake cycles (poly-nap protocol), so that sleep episodes occur at different circadian phases. Vigilance, attention, risk behavior as well as sleep onset latency will be observed. Ambulatory accelerometer recordings gain more and more attention in the diagnostic work-up of sleep disorders, as they allow to also include the everyday rest-activity rhythm before examinations in the sleep laboratory. Advances of novel devices should improve the detection of rest and activity and therefore the estimation of sleep and wake, especially in patients with neurologic sleep-wake disorders exhibiting fragmented sleep. Two types of actimeters will be applied throughout our study protocol to explore better classification of sleep and wake phases and patterns of the rest-activity rhythm. This study is designed as an observational case-controlled study targeting the disorders of narcolepsy type 1 and idiopathic hypersomnia, and including interventional procedures in the healthy control group (sleep deprivation, sleep restriction) in a counter-balanced design.

The purpose of this study is to determine the relationship between sleep disorders and cerebral hemodynamics.
