Active clinical trials for "Dyssomnias"

This study will investigate sleep behavior in subjects with Angelman Syndrome, Rett Syndrome or Prader-Willi Syndrome. The study will also investigate sleep behavior in healthy siblings of subjects with Angelman Syndrome, Rett Syndrome or Prader-Willi Syndrome. These individuals will serve as control subjects. The study will use questionnaires designed to identify sleep disorders and how they affect behavior and quality of life. The principal goals of this study are: To see how common sleep disorders are in individuals with Angelman Syndrome, Rett Syndrome or Prader-Willi Syndrome; To see how sleep disorders affect behavior in these individuals; To see whether sleep disorders and related behavior problems improve or worsen with age; To see how specific disease conditions relate to sleep disorders and how bad the sleep disorders are; To develop new treatment options to improve quality of life and behavior issues; and To evaluate current treatment options to improve sleep problems in these individuals.

Sleep disruptions are prevalent complaints in cocaine use disorder (CUD) subjects, either during consumption or withdrawal. Repetitive transcranial magnetic stimulation (rTMS) seem to be a promissing strategy in the treatment of chronic cocaine users. The aim of this study will be to assess the variation on self-perceived sleep quality and drug use variables in individuals with CUD undergoing a rTMS protocol over the left dorsolateral prefrontal cortex (DLPFC).

This research will assess the ability of nightly objective sleep scheduling and sleep heart rate data to predict variation in suicidal ideation in U.S. military veterans identified as high-risk according to actuarial and/or clinical indicators. These data will be recorded using one of two low-cost, commercial, zero-burden, mattress actigraphic systems that enable remote, centralized, data access. Participants will be veterans accrued both from the REACH VET and local high-risk lists, a process involving collaboration with the Suicide Prevention Coordinator at the VA Palo Alto HCS. In order to minimize burden, participants will be screened by telephone, consented by mail and telephone, administered a brief admission psychometric interview by telephone, and mailed a sleep sensor system and instructions for its installation in their home. Once sleep data collection has commenced, a trained interviewer will contact the participant by telephone weekly and administer the Columbia-Suicide Severity Rating Scale. Data collection will continue for three months. The study targets a sample of 40 veterans. Longitudinal mixed effects modeling will be employed to determine whether changes in sleep scheduling and sleep heart rate predict changes in suicidal ideation.

We aim to observe the unwanted effects of nightshift work and short term insomnia on erectile function of men aged between 25 to 60 years. We will also compare the levels of serum testosterone in the target group and compare it with the ones who don't work in hightshifts.

In this study we would like to clarify the effect of long lasting Crohn's Disease on motility of the gastrointestinal system in patient and the effect regarding sleep disturbances. This will be done with a newly developed 3D-Motility-and-Transit-detector (Motilis Medica, Schweiz) and the well known polysomnographic equipment. Our hypothesises are: Patients with ileocoecal and/or colonic CD in remission and gastrointestinal symptoms have abnormal colonic transit (primary endpoint). Patients with ileocoecal and/or colonic CD in remission and gastrointestinal symptoms have abnormal gastric emptying and small intestinal transit (secondary endpoints). Total and segmental transit times found in patients with CD will be compared with corresponding transit times in healthy volunteers found in a previous study. Patients with ileocoecal and/or colonic CD in remission have abnormal sleep patterns. Nocturnal basic colonic activity, have changed in patients with ileocoecal and/or colonic CD in remission and sleep disturbances.

RATIONALE of the project. Adults with Down syndrome (DS) present severe sleep disorders that are under recognized by caregivers. Aging in DS population increases the prevalence of both Obstructive Sleep Apnea (OSA) and Alzheimer´s disease (AD) dementia at much higher rates than in the general population. AD increases the risk of sleep disturbances and OSA, which in turn worsen cognitive performance and behavioral function. Our hypothesis is that adults with DS and AD dementia will present a higher prevalence of sleep disorders (sleep disruption, sleep circadian disorders and OSA) than in DS without dementia. There are no data evaluating nocturnal sleep in adults with DS with AD dementia. The main objective is to evaluate the prevalence of sleep disturbances in adult subjects with DS and AD dementia, by means of subjective and objectives sleep measures.

This project aims to build up the comprehensive database of geriatric medicine for local Taiwanese.

Hypotheses: Hypothesis 1 - Sleep can be measured in Theater using actigraph technology. Hypothesis 2 - Standard sleep measures in Soldiers randomized to a sleep intervention group will more closely approximate normal as compared to sleep measures of Soldiers randomized to the control group.

Sleep problems become more prominent with aging and worse among post-menopause than perimenopause stage. The actual causes of sleep problems are unclear. However, it occurs commonly accompanied with or in the response of seriousness of menpausal symptoms as nocturnal hot flashes, mood disorders, and obstructive sleep apnea among menopauses. The Prevalence of sleep problems is variable ranged from 11.8 -62 % based on different studies. Cognitive-behavioral therapy (CBT) is one of the short-term form of psychotherapy, used for managing sleep problems and insomnia , an efficacious as pharmacological treatment.

This study will inform the field about underlying mechanisms associated with infant sleep problems and will deepen the understanding of the intervention process. The study will provide detailed information on the intervention process itself and will explore how behavioral sleep interventions affect broader infant outcome.
