Active clinical trials for "Dyssomnias"

Sleep problems can lead to a bad quality of life and a raise of morbidity, also in dialysis patients. Sleep problems can be caused by a disturbance of circadian rhythms in our body. For a good regulation of these circadian rhythms a uniform external synchronisation is necessary. This is the synchronisation of the biological clock of our body by light and other influences. In case of a disturbance of the external synchronisation, due to for example naps during the day or wake periods at night, internal rhythms can be unlinked. As a result a weakened melatonin rhythm and a problematic sleep-wake cycle can be observed. Most dialysis patients have sleep problems. Their sleep latency is prolonged. They often take a nap during the day and their sleep efficiency is poor. There has only been one study on the melatonin rhythm of dialysis patients. The conclusion of this study was that the melatonin rhythm of dialysis patients is weakened and disturbed, probably caused by renal insufficiency. In this study no link was made between melatonin rhythm and the nature and severity of possible sleep problems. In different studies with non-dialysis patients and a disturbed melatonin rhythm, exogenous melatonin at the right time leads to a recovery of the normal rhythm and the normal biological clock and a better quality of life. The aim is to research the endogenous melatonin rhythm and to improve sleep problems of hemodialysis patients with a placebo-controlled study with exogenous melatonin. Next to this a substudy is performed, in which the effect of the change of daytime to nocturnal in hospital hemodialysis on sleep and melatonin is researched.

This protocol is a multicenter clinical trial of melatonin for sleep disturbances associated with Alzheimer's disease (AD). Frequent nocturnal awakening is a common behavioral symptom of AD. Nighttime wandering and agitated behavior may result in injuries and sleep disruption for caregivers. Alternatives are sorely needed to the currently available sleep medications that have marginal efficacy and serious side effects. Melatonin is a naturally occurring hormone secreted by the pineal gland. It has soporific effects with oral administration and is well tolerated. It enhances sleep in normal older people. Melatonin also may help sleep disturbances associated with AD; however, this remains to be proven.

The overall aim of Dr. Levenson's research proposal is to test the acceptability, feasibility, and preliminary outcomes of a sleep promotion program delivered to 13-15 year olds who report insufficient sleep. Dr. Levenson will examine the feasibility and acceptability of the program through a randomized pilot trial (n=40) that uses a two-period, wait-list control design. Then, Dr. Levenson will test whether the program is associated with changes in sleep, motivation, and four outcome domains: academic functioning, attention, risk behavior, and affect. Such a broadly relevant program has the potential for enormous public health impact by improving sleep and facilitating healthy development across a range of domains among typically-developing adolescents who are highly vulnerable to adverse consequences.

The study was a randomized controlled trial designed to examine whether augmenting traditional sleep hygiene and stimulus control procedures with technology use reduction stimulus control procedures would produce better sleep and technology usage outcomes.

Investigators will enroll up to 120 parent-child dyads from Children's Hospital of Philadelphia (CHOP) urban primary care clinics. The primary objective of this randomized clinical trial is to determine the whether the Sleep Well! behavioral sleep intervention is feasible and acceptable to families. The investigators will also examine the direction and magnitude in any change in child sleep and child behavior.

The use of amber glasses will aid the patient to fall asleep without the need for the use of hypnotic medication.

The investigators are conducting a randomised-controlled trial comparing coherent breathing at ~5.5 breath cycles per minute-bcpm (with equal inhalation/exhalation durations of ~5.5secs each) to a well-designed placebo (paced breathing at 12bcpm with equal inhalation/exhalation durations of 2.5secs each). The metric of 12bcpm is in line with guidance from the British Journal of Nursing, Royal College of Physicians, and Johns Hopkins University which state that the average, healthy bcpm should range from: 12-20bcpm, 12-18bcpm, and 12-16bcpm, respectively, hence the investigators chose the minimum/lower bound for the active placebo control group. The main questions that our study attempts to address are: Does coherent breathing (and placebo coherent breathing) lead to improved mental health and wellbeing in a general population adult sample? The study will be conducted entirely online through the research platform Prolific, so participant data will be anonymous. The investigators will collect self-reports of mental health and wellbeing before and after the four-week breathwork period, along with a follow-up one-month later. Pre-post intervention and follow-up questionnaires will be completed online via the survey platform Qualtrics which will be linked to Prolific. Participants will also be asked how many times they practiced out of the assigned 28 days, to gauge self-reported adherence to the protocol. The investigators can then observe whether self-reported adherence correlates with changes in mental health and wellbeing, if any. Data on the self-reported credibility/expectancy of the breathwork randomly allocated to participants will also be collected, along with open-ended responses on participants' overall experience of the protocol/study.

The investigators will conduct a randomized controlled trial comparing a telephone based intervention (TCM) to usual care (UC). TCM will feature a registered nurse providing a series of phone calls to assist caregivers in learning and modifying behavioral strategies that may help young children with autism to sleep better. Objective (activity monitors) and subjective (rating scales) data will be collected by an independent research assistant at the end of the project. The investigators hypothesize that TCM improves sleep duration and decreases sleep problems relative to a usual care control condition (UC).

In conjunction with investigators at the Cecil G. Sheps Center for Health Services Research, University of North Carolina (UNC) at Chapel Hill, we propose to develop and evaluate a low-cost, minimally obtrusive device that delivers individualized light therapy to adults with early-awakening insomnia - the most common sleep disturbance in older adults, and a significant problem because of its relationship to daytime sleepiness, use of potentially hazardous sleep medication, and reduced quality of life. The proposed device will measure light/dark exposure data over 24 hours, estimate optimum timing for light delivery, and deliver an individualized light dosage while subjects are asleep. Light applied through closed eyelids in the early part of the night will delay the dim light melatonin onset, a marker of the circadian clock, and help those with early sleep onset to fall asleep later

Purpose: The objective of this study was to evaluate the influence of a session of resistance training on the sleep patterns of elderly people. Methods: Forty men aged 65 to 80 years, sedentary and clinically healthy were divided into two groups: the control group (n=18) and the resistance group (n=22). Both groups underwent two polysomnography tests, one at baseline and another after either a resistance training session (One Repetition Maximum - Strength Test, resistance group) or without physical exercise (control group).
