Filter by:There is increasing evidence that chronic sleep disorders in children with autism spectrum disorder (ASD), Angelman Syndrome (AS) and Smith-Magenis syndrome (SMS) are associated with disturbed melatonin secretion and melatonin administration has been shown to be effective in these populations. For children who have difficulties swallowing a tablet, Neurim has developed an age-appropriate Melatonin formulation in the form of mini-tablets which have the same dissolution profile as the Circadin® tablets product, thus should produce the same melatonin concentration-time profile with the same effects. This study concerns the pharmacokinetic study. The purpose of this study is to : - Establish the 24 hour baseline profile of endogenous saliva melatonin concentrations and urine 6-SMT excretion in children aged 2 up to and including 17 years with neurodevelopmental disorders with sleep disturbances. - Establish the concentration-time profile of saliva melatonin concentrations and 24 hour 6-SMT urine excretion after 2 and 10 mg Circadin® mini-tablets single dose administration in children aged 2 up to and including 17 years with neurodevelopmental disorders with sleep disturbances. - Evaluate the adverse event profile after a single dose of 2 or 10 mg Circadin® mini-tablets in children aged 2 up to and including 17 years with neurodevelopmental disorders with sleep disturbances.
The hypothalamus is a part of the brain containing a number of nuclei with a variety of functions. It is central in the regulation of hormone secretion, sleep, and circadian functions. The suprachiasmatic nucleus of the hypothalamus is a key component in controlling circadian rhythms and generates the rhythm of melatonin secretion from the pineal gland and cortisol secretion. Both melatonin and cortisol are involved in the regulation of circadian rhythms and sleep. Craniopharyngiomas are a type of brain tumors that usually affect the hypothalamus indirectly. In general, they are locally aggressive invading crucial structures e.g. the hypothalamus, the pituitary, and the optic nerve. Compared to healthy controls, craniopharyngioma patients have previously been reported with impaired quality of life, increased self-reported general and physical fatigue, increased daytime sleepiness, and increased prevalence of severe sleepiness Damage to the hypothalamus by local tumour or its treatment might involve the suprachiasmatic nucleus and thereby melatonin secretion leading to disturbed circadian function causing clinical manifestations in terms of daytime sleepiness and fatigue. The investigators aimed to assess the influence of craniopharyngiomas or their treatment on melatonin secretion, and the association with sleep pattern, sleep quality, fatigue, and sleepiness. 15 patients with craniopharyngioma and 15 gender, age, and BMI matched healthy controls were included. Salivary melatonin and cortisol were measured over a 24h-period. Sleep-wake patterns were characterized by two weeks of actigraphy recordings and sleep diaries. Sleepiness, fatigue, sleep quality, and general health were assessed by questionnaires.
Little is known on the prevalence of sleep disorders and their role in the increased prevalence of cardiovascular diseases in the developing world. We To assess the prevalence of major sleep disorders in a rural South American population, and to determine whether these conditions are associated with a poor cardiovascular health or with the occurrence of stroke or ischemic heart disease. This is a three-phase, population-based, door-to-door survey in Atahualpa. During phase I, all residents aged ≥40 years will be screened with validated Spanish versions of five questionnaires to evaluate major sleep disorders. In phase II, neurologists will examine persons suspected of having a sleep disorder and a random sample of negative individuals to assess the prevalence of these conditions and to validate the accuracy of questionnaires. In phase III, patients with a confirmed sleep disorder will undergo nocturnal polysomnography for achieving a more specific diagnosis. The occurrence of sleep disorders will be correlated with the cardiovascular health of the population as well as with the presence of stroke and ischemic heart disease. This epidemiological study may prove cost-effective in improving sleep conditions of people living in rural areas of developing countries, and may be used as a model for the evaluation of sleep disorders and their cardiovascular correlates in these populations.
The purpose of this study is to determine whether mirtazapine is effective in the treatment of sleep disorders in Alzheimers disease.
Post traumatic stress disorder (PTSD) has emerged as a significant problem among troops returning from combat zones. A majority of these veterans will report difficulty maintaining or initiating sleep. The purpose of this research will be to conduct a prospective, randomized, wait list controlled, small scale feasibility study to examine if the use of an auricular acupuncture regimen improves quality of sleep for Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF)veterans with PTSD receiving standard PTSD treatment. Hypothesis: Objective and subjective sleep disturbances and sleep quality will be improved in OIF/OEF veterans who receive auricular acupuncture in conjunction with standard PTSD therapy or standard therapy alone.
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
Sleep is an essential component of good physical and mental health. Previous studies have reported that poor quality sleep is associated with an increased risk of hypertension, stroke and cardiovascular disease (CVD). Hypertension is the most common and important risk factor for CVD, and even modest reductions in blood pressure result in significant reductions in stroke and myocardial infarction. In this randomised trial, the investigators aim to evaluate whether a simple, multi-component, online sleep intervention reduces blood pressure in patients with essential hypertension.
Due to the development of neonatal intensive care the number of surviving premature infants increased significantly. The immature brain undergoes a fair amount of external stimuli, which have a great impact on later cognitive development. Increasingly data show, that a delayed emergence of sleep-wake-cycling in newborns can be the first sign of brain injury. Studies have shown that clearly defined sleep states can be identified from 31-32 weeks of gestation onwards. But a few studies show, that also extremely premature infants already show cyclical variations of the background pattern within amplitude-integrated EEG (aEEG= a time-compressed, simplified EEG) and conventional EEG. This might resemble early sleep-wake-states and their presence correlates to the integrity of the central nervous system, although no clearly defined "sleep states" according to the classical definition can be identified. Complex EEG analysis needs the use of automated methods to exclude personal bias and to ensure gestational age specific data analysis. The newly developed NLEO algorithm was specially designed for EEG analysis of premature infants. Conventional EEG within this study will be analyzed visually and with the automated algorithm. In our research project we will study the emergence of Sleep-wake-cycling in extremely premature infants and its impact on their neurodevelopmental outcome prospectively. The different sleep and wake states will be derived from analysis of the conventional Video-EEG, aEEG and polysomnographic measurements. Visual analysis will include assessment of amplitudes and frequencies as well as the latencies and durations of EEG-Bursts and Interburst intervals. The automated NLEO-algorithm will be firstly used for comparison with above described visual analysis and secondly to find regions of interest involved in the organization of these early sleep states. The aim of this study is first to understand and analyze in detail the emergence of sleep-wake cycling including its disturbances in premature infants and to compare automated NLEO algorithm to conventional visual analysis methods. Secondly to correlate neurodevelopmental outcome to the emergence of sleep-wake-cycling.
Individuals with bipolar disorder (BD) experience extreme mood swings, or episodes of depression and (hypo)mania. These episodes are associated with poor functioning, worse course of illness, and high rates of suicidality. It is estimated that between 25 to 65% of individuals with BD attempt suicide and 4 to 19% of individuals with BD eventually die by suicide. Sleep disturbance has been identified as a primary prodromal as well as causal symptom of mood episodes and recently, has been found to be associated with higher rates of suicidal ideation and behavior. Given the role that sleep may have in mood stability and suicidality in BD, it seems imperative to further understand the association of sleep and suicide and how sleep interventions may be useful to reduce suicidality in BD. Thus, the primary aim of this study is to use an innovative home sleep monitoring device, or the Embla, to examine the association of sleep and suicidality in adult outpatients with BD. The Embla is unique in that it is a non-invasive device that can characterize sleep profiles by measuring the degree of sleep fragmentation and percentage of rapid eye movement (REM) sleep. The study duration is five to six weeks such that patients wear the Embla device for Week 1, participate in a brief sleep intervention for suicide during Weeks 2 and 3, and 4, and then wear the Embla device for one more week (Week 5). This intervention consists of three, 60-min sessions and utilizes cognitive-behavioral therapy strategies (e.g., psychoeducation, cognitive re-structuring, problem solving, behavioral activation) to improve sleep disturbance. The investigators expect that individuals at study entry with more sleep disturbance (as measured by the Embla) will report more suicidal ideation and behaviors. The investigators also hypothesize that from pre- to post-intervention, individuals will report less sleep disturbance as well as suicidal ideation and behaviors. Data from this research has immediate and practical implications for providers and their patients as it the first examination of sleep phenotypes and suicide in a high risk population as well as to explore the association of improvements in sleep with suicidality.
The investigators propose to investigate the efficacy of a brief (4-session) Body Scan (BS) meditation intervention for individuals with bipolar I disorder with insomnia (i.e. difficulties falling or staying asleep). The investigators will compare the Body Scan intervention with a 4-session brief supportive psychotherapy (SP) intervention. The investigators hypothesize that the Body Scan will improve objective sleep quantity and quality.
