Active clinical trials for "Dyssomnias"

To investigate the effect of trazodone on sleep, hippocampal-dependent memory and hippocampal excitability. The investigators hypothesize that trazodone will improve total sleep time and proportion of time in Slow Wave Sleep (SWS).

Insomnia and daytime sleepiness are common complaints among night shift workers, but effective sleep treatments in shift workers are lacking. The aim of this Phase IV double-blind, placebo-controlled, randomized study is to test whether a dual orexin antagonist, Lemborexant (5mg or 10mg), which would be expected to block the clock-driven orexin-mediated wakefulness during the day, will increase daytime sleep time in shift workers who complain of difficulty sleeping during the daytime compared to placebo.

This randomized controlled trial will evaluate the impact of an Internet-delivered cognitive behavioral therapy for insomnia (CBT-I) intervention on sleep and the extent to which it contributes to cognitive health in individuals with mild cognitive impairment. Participants with insomnia who meet the study criteria for mild cognitive impairment will be recruited to determine the effects of the CBT-I intervention compared to a patient education condition on sleep and cognition. Internet-based recruitment methods will be used, and outcomes include sleep variables, daytime variables, and cognitive status.

the aim of this study is to investigate the efficacy of resistive exercise on insomnia in post menopausal women

Delirium is a frequent and serious problem in hospitalized patients; it is associated with multiple hospital-acquired complications. There is evidence that the incidence of deliri-um may be minimized by multimodal interventions (pain management, shortening the duration of mechanical ventilation, light sedation, avoiding benzodiazepines, routine delirium monitoring, and early mobilization). Even though a clear association between sleep and delirium has not been established, many studies suggest that sleep disturban-ces may be a key risk factor for the development of delirium. Therefore, sleep promoti-on is becoming an integral part of clinical care. The project support the hypothesis that non-pharmacological preventive interventions promoting sleep (sleep protocol) positive-ly influence the quality of sleep and reduce the incidence of delirium in hospitalized patients. This will be verified by qualitative and quantitative research methods, with the quantitative study being divided into three prospective cross-sectional studies and one interventional study. Data will be obtained from 3240 hospitalized patients by combi-ning subjective methods (questionnaire surveys) and objective measurements (acti-graphy). The project outcomes will allow better understanding of the relationship betwe-en sleep and delirium. A set of non-pharmacological preventive interventions promoting sleep will be developed, with a subsidiary aim to potentially reduce the incidence of delirium in hospitalized patients.

The trial aims to evaluate the effects of an integrated form of mindfulness-based Tai Chi Chuan (MBTCC) program and the underlying mechanisms of the beneficial effects on sleep disturbance over 12-month follow-up in community-dwelling elderly people.

The aim of this study is to examine the effect of a non-pharmacological transdiagnostic sleep intervention as add on to standard treatment for bipolar disorder, depression and attention deficit disorder. Our hypothesis is that the intervention will reduce the severity of the sleep problem and increase sleep quality compared to a control group receiving sleep hygiene education.

Aim 2 will investigate the effect of 3 different light exposure lengths on sleep, mood and agitation in persons with Alzheimer's disease. Participants will be randomly assigned to one of three conditions of light exposure: 1) 2-h morning light exposure; 2) 4-h morning light exposure; and 3) all day light exposure.

Long-term pain affects one-third of the United Kingdom population and can be very disabling. People experiencing long-term pain often suffer from disturbed sleep because of their pain symptoms, and disturbed sleep can then make their pain symptoms worse. Managing long-term pain is also very costly to the National Health Service. The most common treatment is prescribed medicines, but these do not always work and can have serious side-effects for some patients. The investigators have been developing an alternative approach for treating long-term pain. This approach uses simple non-invasive tools to promote some kinds of brain activity over others. It involves patients using headphones to listen to some specific sounds, or a headset with lights flashing at particular frequencies. The studies undertaken so far seem to show that doing this can change how the brain responds to pain. It potentially offers an inexpensive yet effective way of reducing pain and improving sleep for patients with long-term pain. There are a few small studies that support this approach and more work is needed. In a recent study the investigators found that these tools can be reliably used in home settings and there were some indications that they improved symptoms. However, sleep was only measured with sleep diary and movement detection, there was no direct measurement of whether the stimulation frequencies were resulting in the desired brainwave changes. Finally, the benefit to symptoms may have been the result of other factors, such as the passage of time or placebo effect. Therefore this study extends the experiment, adding more accurate sleep monitoring which includes monitoring electrical activity in the brain (EEG), as well as providing rhythmic and non-rhythmic stimulation in a randomised order. The aim is to further test the effect of these home-based tools with individuals with long-term pain, in a more rigorous way. Up to 30 participants with long-term pain and pain-related sleep disturbance will use the tools for 30 minutes at bed time every day for 4 weeks (2 weeks with one type of stimulation, 2 weeks with another type). The changes in participants' pain, sleep, brainwave frequencies, fatigue and mood will be measured. These findings will inform the planning and design of a future much larger study to test this technology, if this is justified by the results.

Sleep disturbance has a range of negative effects on psychosocial and biological processes important for academic and social success as well as mental and physical health among adolescents and young adults. Limited, inconsistent, and poor quality sleep lead to anxiety, depressive feelings, loneliness, and fatigue over time. These symptoms, in turn, interfere with the ability to get a good night's rest. Sleep disruption can also upregulate inflammatory processes during the years of adolescence and young adulthood in ways that can create risk for the development of chronic health conditions (e.g., diabetes, depression, cardiovascular disease) in later adulthood. Sleep, however, is also a modifiable health behavior, leading many institutions to embark upon efforts to improve the sleep of their students. The challenge is to identify programs and interventions that can simultaneously improve sleep, be delivered at scale, and be easily completed by students. UCLA has developed and validated a group-based mindfulness intervention, Mindful Awareness Practices (MAPs), that has demonstrated beneficial effects on sleep in adults and may offer a promising, scalable approach for reducing sleep disturbance and improving associated psychological and biological outcomes in college students. However, this approach requires validation in this population relative to sleep education programs, which increasingly dominate the college landscape. To address this important public health problem, the investigators propose to conduct a single site, two-arm, parallel group randomized controlled trial to test the efficacy of the validated, group-based, six-week MAPs intervention vs. sleep education, an active time and attention matched control condition, for first year undergraduate students who report poor sleep at this critical transition year. The investigators are aiming to enroll approximately 240 participants. Participants will complete questionnaires, provide blood samples for immune analysis and will be provided with wrist actigraphs to wear for 7 days, in order to collect objective measurements of sleep at pre- and post-intervention visits, and at a 3-month follow-up visit. Additional follow-up assessments will take place at 6-month, and 12-month post-intervention to evaluate persistence of effects.
