OBJECTIVE To determine some personality and psychoneurotic characteristics of adults who have the sleepwalking-night terrors syndrome. DESIGN Prospective assessment of two groups of consecutive patients with a firm diagnosis of either of two specific sleep disorders as established clinically and by polysomnography. SETTING Outpatient sleep disorders clinic and sleep laboratory in a tertiary...

This study was conducted to investigate the effect of the exposure to dim light during sleep on the brain activation while conducting tasks requiring working memory. 23 young healthy subjects participated in this study. The subjects were instructed to sleep in a polysomnography room with no light exposure on the first night and under a dim light condition of 5 lux or 10 lux on the second night....

PURPOSE We describe the influence of vagus nerve stimulation (VNS) with standard mode and rapid cycling mode on sleep related breathing in two patients with epilepsy. METHODS Two VNS treated patients underwent digital video-polysomnography for three nights (night 1: rapid cycling mode; night 2: standard mode; night 3: off mode). RESULTS In patient 1, on off mode, apnea-hypopnea index (AHI) ...

Night-to-night variability of apneas on overnight polymnography exists in patients with documented obstructive sleep apnea (OSA). In this study, we evaluated the possibility that this variability may be severe enough to miss the diagnosis of OSA in patients clinically at risk for the disease. We prospectively studied 11 patients who were deemed on clinical grounds to have probable OSA, but had ...

background and objective: failure in diagnosis and treatment of sleep apnea in children lead to physical and mental growth retardation, cardiopulmonary, and/or behavioral disorders. this study was aimed to evaluate polysomnographic (psg) and clinical findings of sleep apnea in children referred to a sleep clinic in qazvin, iran. materials and methods: this cross-sectional study was conducted am...

BACKGROUND Diurnal emotional experiences seem to affect several characteristics of sleep architecture. However, this influence remains unclear, especially for positive emotions. In addition, electrodermal activity (EDA), a sympathetic robust indicator of emotional arousal, differs depending on the sleep stage. The present research has a double aim: to identify the specific effects of pre-sleep ...

STUDY OBJECTIVES To assess the accuracy of a wrist-worn device (Watch_PAT 100) to diagnose obstructive sleep apnea in the home. DESIGN Participants completed 2 overnight diagnostic studies with the test device: 1 night in the laboratory with concurrent polysomnography and 1 night in the home with only the Watch_PAT. The order of the laboratory and home study nights was random. The frequency o...

STUDY OBJECTIVES The primary aim of this study was to determine the prevalence of positional obstructive sleep apnea using a functional definition. Positional sleep apnea was defined as a total apnea-hypopnea index (AHI) > or = 5 with a > 50% reduction in the AHI between the supine and nonsupine postures, and an AHI that normalizes (AHI < 5) in the nonsupine posture. A secondary aim was to dete...

OBJECTIVES To examine the sleep of married couples, recorded together in the laboratory before and after the husband is treated with continuous positive airway pressure (CPAP) to control his obstructive sleep apnea (OSA). The purpose was to investigate how these data relate to shared sleeping when he is on CPAP and his adherence to this treatment. METHODS Following a split-night diagnosis of ...

Background: We compared the density and duration of sleep spindles topographically in stage 2 3 non-rapid eye movement (N2 N3) among adults diagnosed with Obstructive Sleep Apnea Syndrome (OSAS) healthy controls. Materials Methods: Thirty-one individuals OSAS (mean age: 48.50 years) 23 controls took part study. All participants underwent a whole night polysomnography. Additionally, those were d...
