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.

Sleep disordered breathing (SDB) is characterized by regular periods of no breathing (apnea) or low levels of breathing (hypopnea) and leads to repeated periods of low oxygenation, termed intermittent hypoxia that causes fluctuations in blood oxygen levels. This leads to increased peripheral chemoreflex sensitivity that is thought to occur through the stimulation of angiotensin-II, type-I receptors (AT1R) that are expressed primarily on glomus cells within the peripheral chemoreflex and ultimately results in long lasting hypertension. The goal of this study is to determine if AT1R receptor blockade can prevent the increase in chemoreflex sensitivity following one night of hypoxia and improve the severity of SDB.

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.

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.

The Nightly medical application prototype is a potential, non-invasive class I medical device. The application has the potential to combine both diagnostic and therapeutic procedures for sleep. At home, Nightly measures the user's motion during sleep and then records the sleep pattern from the received data. The obtained data are then used for the diagnosis of sleep disorders (REM and NREM sleep). Using acoustic and visual stimulation, the application has the capability to support the natural process of falling asleep, provide a better night's sleep by minimizing sleep deprivation and nightmares, while awakening the user at the appropriate moment (during light sleep).

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.

Shift work deeply impacts on temporal organization leading to a circadian desynchronization, which translates into a worsening of the sleep quality and work ability during waking hours. Furthermore, also the fine motor control skills and the subjective mood profile could undergo modifications in relation to the acquired sleep debt. The misalignment between working time and physiological/behavioral functions could have negative influences on the levels of spontaneous daily activity, with possible alteration of the activity-rest rhythm of the worker, especially in clinics. In relation to the participants' chronotype, the aim of this project will be to evaluate the effect of irregular working hours (shift work) on (i) the sleep quality, (ii) the circadian rhythm of activity levels and, (iii) the motor control. These assessments will help to identify the shift type with less impact on the health status in a nurse cohort.

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.
