Filter by:Prior research studies have shown benefit for use of a technique called High-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM®), to reduce symptoms of moderate to severe insomnia. HIRREM uses scalp sensors to monitor brain electrical activity, and software algorithms translate selected brain frequencies into audible tones in real time. Those tones (acoustic stimulation) are reflected back to participants via ear buds in as little as four milliseconds, providing the brain an opportunity to self-adjust and balance its electrical pattern. The purpose of this research study is to determine the effects of HIRREM-SOP, an updated version of this technology that is based on the HIRREM approach, but now includes new hardware and software, a standardized series of HIRREM protocols, and a fixed number of sessions. Adults over the age of 18 who have documented sleep trouble that place them in the category of subthreshold (mild), moderate, or severe clinical insomnia as defined by the Insomnia Severity Index, are eligible to participate in the study.
This study is a randomized, single-blind, sham-controlled pilot cross-over trial comparing the feasibility, and efficacy of 2 nights of in lab use with active versus sham conditions in adults with sleep restricted schedules. The study involves the testing of 2 different prototypes both in the sham and active conditions The expected duration of the study for each participant is up to 5 weeks. It will include adults (21-50 yr. old) who report shortened sleep due to lifestyle. For the purposes of this study, shortened sleep is defined as sleeping at least 5.5 of sleep per night, and sleeping less than or equal to 7 hours of sleep +/- 15 minutes on at least 3/5 work/school nights. Participants also increase their sleep duration by ≥ 1 hour on non-work/school days. In addition, participants report a sleep latency ≤ 30 minutes and wake after sleep onset ≤ 30 minutes. Participants are generally healthy individuals who have not been diagnosed with any sleep-related medical conditions such as obstructive sleep apnea, insomnia, difficulty falling asleep on a nightly basis and deny difficulty staying asleep if awoken during sleep. In addition, participants diagnosed with major organ system diseases or requiring oxygen therapy are excluded from participation. Up to 60 individuals will be consented in order to complete a total of 10 participants using a cross over design. The study involves an initial screening visit followed by 1 week of actigraphy measurement to determine eligibility. Post eligibility, participants will undergo an additional week of actigraphy measurement. Participants will complete 2 overnight visits in the sleep lab per week, with one washout night in between. They will be randomly assigned to sham or active condition during the first of the overnight visits, and the other condition during the second overnight condition. Participants will return to the lab on the same nights the next week and receive the second device in both conditions. Participants will be asked to complete a battery of cognitive tests upon wake up in the lab after each of the overnight visits.
The project is aimed at identifying how the adrenergic antagonist 'carvedilol' modulates the effects of sleep deprivation in healthy volunteers. The study is a double-blind, randomized, placebo-controlled, cross-over study. Investigators will include 20 healthy volunteers who will undergo three functional magnetic resonance (fMRI) imaging sessions, one at baseline, and two after sleep deprivation (one night without sleep). The two sleep-deprivation scans are performed in a randomized order where subjects receive placebo or carvedilol, in a within-subject, cross-over study design. The following domains will be described: 1) fMRI imaging of cerebrospinal fluid (CSF) pulsations (glymphatic flow) in the human brain, performed by a combination of fMRI protocols that includes structural (T1, T2, diffusion weighted) and functional (multiband/fast imaging, spectroscopy) imaging. 2) fMRI imaging during wakefulness and sleep are determined by simultaneous electroencephalographic (EEG) recordings. 3) The effects of sleep deprivation on the fMRI derived glymphatic flow signal. 4) The effects of the adrenergic antagonist carvedilol on fMRI measurements and sleep intensity. 5) Quantification of cognitive performance before and after a nap in the MRI. Cognitive testing includes: assessments of visual attention, reaction time, paired-associative memory, working memory, emotional recognition and subjective ratings of sleepiness and mood.
The study aims to develop and test a user-friendly, accessible approach to sleep assessment which can function as an initial "triage" of targeted sleep conditions, such as insomnia, insufficient sleep syndrome, sleep apnea syndromes/snoring, and circadian sleep/wake disorders, within the clinical and community population. Specifically, this study will test the validity and reliability of a self-rated, digitized, and cost-effective diagnostic measure with sufficient sensitivity to accurately assess/diagnose common sleep conditions and/or risk for these conditions. Such an approach, would allow for faster assessment of common sleep conditions and disorders, and provide clinical knowledge to the individual, the physician, and if required insurance companies, as to those persons who need more immediate attention or treatment for their sleep condition.
7 to 14 days actimetry recording in order to exclude sleep deprivation just before hospitalisation for differential diagnosis of hypersomnia
This study plans to learn more about how sleep loss impacts the way the body responds to sugar. This work will have important implications for development of treatments and countermeasures for people who are not able to get enough sleep for various reasons.
The investigator showed that a night of sleep deprivation halved the duration of an inspiratory endurance test and that this loss of endurance could be secondary to a lack of activation of the pre-motor cortex. However, the inspiratory endurance test is associated with a feeling of dyspnea that could lead to premature arrest, and the inspiratory drive is complex, both automatic and voluntary. The investigator can reproduce this results on a simpler drive. During the execution of an exercise involving repeated contractions of the hand it is possible to record the activation of the pre-motor cortex corresponding to the phase of preparation of the movement. The amplitude of these premotor potentials is proportional to the developed motive force. The purpose of this study is to assess the impact of sleep deprivation on the muscular endurance of non-dominant in healthy subjects. Hypothesis: Sleep deprivation causes a decrease in manual motor endurance by decreasing cortical pre-motor control. Main objective: To compare the motor endurance of healthy subjects after a night's sleep and after a sleepless night. Secondary objective: To compare the amplitude of premature cortical control at the beginning of the endurance test after a night's sleep and after a sleepless night.
The primary objective of this study is to evaluate the impact of provision of a child bed through the Beds for Kids program on objectively measured child sleep, and on daily child behavioral functioning and caregiver functioning over a 14-day period for preschool-aged children.
This intervention study will investigate the effect of therapy light rooms on sleep, circadian rhythms, mood, behavioural problems and function in nursing home (NH) patients with dementia.
The purpose of this study is to compare a 2-lead frontal electroencephalogram recording to a formal polysomnography (PSG) in detecting sleep vs. wake and depth of sleep in both healthy and ICU patients.
