Filter by:Obstructive sleep apnea syndrome (OSAS) is considered to be a major public health problem. The prevalence of OSAS is estimated at 2% and 4% for adult women and men respectively, most of whom are undiagnosed and untreated. The prevalence of snoring in children is high - 5% in the age group of 6 and less and about 1.5% above. The in-lab sleep study using full Polysomnography (PSG) and the manual scoring criteria set by the American Academy of Sleep Medicine was considered the gold standard for OSAS diagnosis. The high cost of in-lab full night PSG, together with long waiting lists for sleep studies, have led to the commonly used procedure of "split-night" for OSAS patients, as well as to the development of a variety of ambulatory sleep study systems. The primary study objective is to compare the efficacy of the WatchPAT (WP), as an ambulatory device for aiding in the diagnosis of sleep disorders for subjects from age 5 to 90, to the manual scoring of the PSG that serves as a "gold standard".
Patients with ADHD often report staying up late on the computer, watching TV, or using other electronic devices, all strong emitters of blue light which may be contributing to the delayed sleep onset times seen in some of these patients. Evening use of polarizing glasses which filter out blue light may decrease the contribution of environmental light late at night to delayed bedtime. This is a treatment that Dr. Fargason uses when patients do not want to use sleep medication to help them fall asleep. The purpose of this study is to evaluate the effectiveness of this treatment by use of sleep diaries and sleep questionnaires.
The purpose of this study is to investigate clinical benefits of a novel sleep-focused mind-body program on Gulf War Illness (GWI) symptoms.
The investigators will conduct acupuncture for participants with chronic fatigue syndrome(CFS). Firstly the investigators aim to figure out the characteristic of sleep structure of CFS and the changes caused by acupuncture. Secondly the investigators seek to investigate the characteristic of sleep-wake rhythm, slow wave sleep(SWS)-rapid eye movement(REM)sleep rhythm, and REM sleep rhythm of CFS and the readjusting of acupuncture for it. Thirdly the investigators want to know the efficacy of acupuncture for relieving the fatigue, reducing accompanying symptoms and for improving the life quality of CFS.
The aim of the investigators was to determine whether the immediate management of any detected sleep disorders can improve outcomes in patients who have had a transient ischemic attack (TIA) or minor stroke. This group of patients is at high risk for having a recurrent stroke or TIA, and the investigators would like to investigate new ways of preventing potentially avoidable events. The treatment of sleep disorders immediately after a stroke or TIA may prove to be a novel method of avoiding future strokes and improving outcomes.
RATIONALE: Donepezil hydrochloride may help lessen cognitive dysfunction caused by chemotherapy. PURPOSE: This phase II trial is studying donepezil hydrochloride in treating cognitive dysfunction after chemotherapy in female breast cancer survivors.
The purpose of this study is to determine if participants have changes in dopamine cells in their brain using DaTSCAN™ brain imaging. Dopamine cell loss occurs in Parkinson's disease (PD) and other degenerative Parkinsonian disorders, but does not occur in most other movement disorders such as essential tremor or dystonia. DaTSCAN, which is also known as 123I-Ioflupane, is a new compound that has been developed by General Electric, Inc. and has been approved by the US Food and Drug Administration (FDA) to help doctors detect changes in dopamine. This test is performed by injecting DaTSCAN into a vein in the arm, and after a few hours, a large amount of DaTSCAN temporarily accumulates in an area of the brain where there are a lot of dopamine brain cells. Because DaTSCAN contains a small amount of radioactive iodine, it allows doctors to use a special machine called single photon emission computed tomography (SPECT) scanning to detect the location and amount of radioactivity in the brain and help determine if there are changes in brain dopamine. It is hoped that this study will help doctors detect the presence of dopamine changes even before symptoms are present. This study will evaluate DaTSCAN in people with PD, those who are at risk for developing PD (e.g., those with idiopathic rapid eye movement sleep disorder (iRBD) and those who are heterozygous or homozygous for Gaucher's disease (GBA) mutations) and those who are healthy volunteers.
Cognitive dysfunction, either alone or as an element in the syndrome of delirium, is a common occurrence with an incidence as high as 75% in intensive care unit (ICU) patients and can independently result in serious consequences including higher mortality rate. Delirium develops through a complex interaction between the patient's baseline vulnerability (risk factors) and precipitating factors such as disruption of sleep that may occur during hospitalization. While sedative-hypnotic agents that are used to facilitate hypnosis and the management of mechanically ventilated patients converge on the neural substrate that mediate endogenous sleep, they do so at different juncture points depending on its molecular mechanism of hypnotic action. Hypnotic agents that modulate the GABAA receptor converge at the level of the hypothalamus while α2 adrenergic agonists converge on sleep pathways within the brainstem. This translational project seeks to determine whether sedation mediated by activation of α2 adrenoceptors (dexmedetomidine) is more like natural sleep than that provided by a sedative agent that modulates the GABAA receptor (propofol). The investigators will examine volunteers who will be monitored continuously by electroencephalography (EEG) and whole-brain functional connectivity by magnetoencephalography (MEG) during each of three sleep stages, namely, that induced by dexmedetomidine, propofol, or saline (natural sleep, control). The two drug-induced sleep regimens will be compared to natural sleep using EEG and brain connectivity by MEG
Study objectives are to determine the efficacy, safety and tolerability of bright light treatment in Parkinson's Disease (PD) patients with daytime sleepiness. Thirty PD patients will be enrolled and equally randomized to bright light or dim-red light treatment. Objective (actigraphy) and subjective (sleep logs/scales) sleep measures will be collected through the baseline and intervention phases of the study. The primary outcome measure will be the change in the Epworth Sleepiness Scale (ESS) comparing the bright light treatment with dim-red light treatment. Secondary outcome measures will include the Multiple Sleep Latency Test (MSLT), global Pittsburgh Sleep Quality Index (PSQI) score, Parkinson's Disease Sleep Scale (PDSS) score, and actigraphy measures. A variety of exploratory analyses will examine the effects of bright light treatment on fatigue, depression, quality of life, cognition, and motor disability. Hypothesis: Bright light exposure will diminish daytime sleepiness and improve night-time sleep in PD patients with daytime sleepiness.
Circadian rhythm disorders are a class of sleep disorders characterized by misalignment between the timing of sleep and the timing of rhythms driven by the biological clock. Light therapy can effectively treat these disorders, but the intensity and duration of light exposure required to do so has limited its practical use. In this study the investigators will test whether pre-exposure to dim light may enhance the response of the circadian system to light therapy. If so, this could result in shorter treatments that would have greater practical applications.
