Active clinical trials for "Sleep Wake Disorders"

This research will examine why sleep restriction reduces the body clock's response to bright light. The results will enable the optimization of the bright light treatment of people who suffer from circadian rhythm sleep disorders, which include shift work sleep disorder, jet lag, delayed sleep phase syndrome and winter depression, thereby improving public health and safety, well-being, mood, mental function, and quality of life.

This clinical trial studies yoga-based rehabilitation in reducing physical and emotional side effects of living with cancer or its treatment. Yoga-based rehabilitation may reduce side effects and improve the quality of life of patients with breast, lung, or colorectal cancer.

This interventional, double-blind, randomized, placebo-controlled pilot study aims to evaluate the effect of a dietary supplementation of a fish hydrolysate Peptidyss on sleep quality and anxiety.

Particulate matter exposure during smoke inhalation provokes inflammatory immune responses in people exposed to burning biomass including fire fighters and civilians. Persistent occupational exposure to particulate matter represents a unique hazard for firefighters, underpinning a burgeoning research area. This trial will evaluate the effects of sleep deprivation and circadian rhythm disruption on the inflammatory response to woodsmoke associated particulate matter exposure. Participants will undergo 2 experimental trials in a randomized cross-over design. Participants will have either an 8-hour sleep opportunity or a 4-hour sleep opportunity prior to reporting to lab for a 45 minute simulated firefighting trial (wood smoke associated particulate matter filtered to 2.5 um at a concentration of 250 ug/m^3, while exercising at a moderate intensity). The effects of sleep restriction and simulated firefighting will be measured.

Mental illness is often chronic, severe, and difficult to treat. Though there has been significant progress towards establishing effective and efficient interventions for psychological health problems, many individuals do not gain lasting benefits from these treatments. The Memory Support Intervention (MSI) was developed utilizing existing findings from the cognitive science literature to improve treatment outcomes. In this study, the investigators aim to conduct an open trial that includes individuals 55 years and older to assess if a simplified version of the Memory Support Intervention improves sleep and circadian functioning, reduces functional impairment, and improves patient memory for treatment.

Insomnia is a prevalent and under-recognized disorder in adolescence, particularly in girls, with long-term repercussions for mental and physical health. This study assesses manifestation of autonomic hyperarousal and vulnerability to insomnia using a sample of male and female adolescents with and without Diagnostic and Statistical Manual (DSM-5) Insomnia Disorder. Outcomes from this study have the potential to inform prevention and treatment interventions for insomnia that can be implemented at a young age before chronic negative sequelae of this common disorder manifest.

Sleep and wakefulness disorders impact 50 to 70 million Americans and insufficient sleep is epidemic with over 50% of Americans reporting less than 7 hours of sleep per night. Health problems associated with insufficient sleep include inflammation, depression and anxiety, diabetes, stress, drug abuse, poor quality of life, obesity, and fatigue related accidents on the job/while driving. While the contribution of sleep to overall health, well-being, and public safety is recognized, no established clinical biomarkers of sleep deficiency exist. Such biomarkers would have utility as road-side biomarkers of sleepiness (e.g., drowsy driving), monitoring on the job fatigue/fitness for duty (e.g., transportation, military ops health care), monitoring sleep health, as well as for clinical diagnostics and measures of clinical treatment outcomes. Thus, investigators designed a controlled laboratory insufficient sleep protocol utilizing metabolomics to identify biomarkers of insufficient sleep. Investigators propose to identify changes in metabolites that consistently occur during insufficient sleep. As an exploratory outcome investigators will examine associated changes in metabolites and cognitive performance during insufficient sleep.

The purpose of the study is to evaluate effects of high rebound mattress toppers (i.e., airweave®) on sleep and sleep-related symptoms. The study will compare effects of use of high rebound mattress toppers versus use of low rebound mattress toppers on sleep and sleep related symptoms and core body temperature during diagnostic sleep studies.

This study evaluates the effectiveness of two online Lifestyle Medicine programs. Participants will be randomized by residence, urban vs. rural, into one of two Lifestyle Medicine programs.

The Healthy Patterns Study intervention is a home-based activity intervention designed to improve symptoms of circadian rhythm disorders (CRD) and quality of life (QOL) in home-dwelling persons with dementia. We will use a randomized two-group parallel design of 200 people with dementia and their caregivers assigned to intervention or attention control groups.
