Chronic sleep restriction (SR) increases sleepiness, negatively impacts mood, and impairs a variety of cognitive performance measures. The vast majority of work establishing these effects are tightly controlled in-lab experimental studies. Examining commonly-experienced levels of SR in naturalistic settings is more difficult and generally involves observational methods, rather than active manipulations of sleep. The same is true for analyzing behavioral and cognitive outcomes at circadian unfavorable times...

In addition to cognitive decline, Alzheimer's disease (AD) is also characterized by agitation and disruptions in activity and sleep. These symptoms typically occur in the evening or at night and have been referred to as 'sundowning'. These symptoms are especially difficult for carers and there are no specific drug treatments. There is increasing evidence that these symptoms reflect an underlying pathology of circadian rhythm generation and transmission. We investigated whether a transgenic mouse model relevant to AD (APPswe/PS1dE9) exhibits circadian alterations in locomotor activity and expression of clock genes involved in the regulation of the circadian cycle...

PURPOSE: Video ambulatory EEG (V-AEEG) is a new technique which could add increased capacity for long term EEG monitoring to overstretched inpatient video telemetry (IPVT) services. We compare V-AEEG and IPVT for diagnostic efficacy, recording quality, patient acceptability and technologist time required. METHODS: Forty-one V-AEEG and 64 IPVT adult patients were included. Patients were investigated to diagnose attacks or to obtain polysomnography (PSG) prior to multiple sleep latency test (MSLT)...

Prior research demonstrates that sleep benefits memory consolidation. But beyond its role in memory retention, sleep may also facilitate the reorganization and flexible use of new information. In the present study, we investigated the effect of sleep on conceptual knowledge. Participants classified abstract dot patterns into novel categories, and were later tested on both previously seen dot patterns as well as on new patterns. A Wake group (n = 17) trained at 9 AM, continued with their daily activities, and then tested at 9 PM that evening...

Sleep apnea, characterized by frequent pauses in breathing during sleep, poses a serious threat to the healthy growth and development of children. Polysomnography (PSG), the gold standard for sleep apnea diagnosis, is resource intensive and confined to sleep laboratories, thus reducing its accessibility. Pulse oximetry alone, providing blood oxygen saturation (SpO2) and blood volume changes in tissue (PPG), has the potential to identify children with sleep apnea. Thus, we aim to develop a tool for at-home sleep apnea screening that provides a detailed and automated 30 sec epoch-by-epoch sleep apnea analysis...

Importance: Drug-induced sleep endoscopy is a diagnostic technique that allows dynamic evaluation of the upper airway during artificial sleep. The lack of a standardized procedure and the difficulties associated with direct visual detection of obstructive events result in poor intraobserver and interobserver reliability, especially when otolaryngology surgeons not experienced in the technique are involved. Objectives: To describe a drug-induced sleep endoscopy technique implemented with simultaneous polygraphic monitoring of cardiorespiratory parameters (DISE-PG) in patients with a diagnosis of obstructive sleep apnea syndrome and discuss the technique's possible advantages compared with the standard procedure...

PURPOSE: Many Veterans Affairs Medical Centers (VAMCs) have implemented home sleep apnea testing (HSAT) in lieu of traditional in-lab testing to establish a timely and cost-sensitive diagnosis of obstructive sleep apnea (OSA). However, concern remains for the sensitivity and specificity of said technology in this population as many veterans are at increased risk for many of the comorbid conditions that can limit the accuracy of HSAT results. Hence, the purpose of this study is to evaluate rate of incongruent outcomes (e...

INTRODUCTION: Little is known about the pediatric population at an increased risk of restless legs syndrome (RLS) and periodic limb movement disorder (PLMD). Polysomnographic data from the Caffeine for Apnea of Prematurity-Sleep (CAPS) study showed a high prevalence of elevated periodic limb movement index (PLMI) in a cohort of ex-preterm children, but the clinical importance of this finding, such as association with RLS, is unknown. We hypothesized that ex-preterm children would have a high prevalence of RLS and PLMD...

Sleep deprivation (SD) impairs vigilance and increases the risk of driving accidents during the commute home after night work. Bright light (BL) can enhance alertness and cognitive performance. We examined the effects of BL (5600 lux) versus dim light (DL, 35 lux) at the end of a night awake on driving performance. METHODS: Subjects (N = 19, 22.8 ± 4 ya) completed three conditions, counterbalanced for order at >1 week intervals. The two overnight SD conditions began in the lab at usual bedtime...

At the onset of puberty, students shift their sleep to later hours, but school starts early. It is suggested that evening orientation and early school start times do not go well together. Therefore, the aim of this study was to investigate sleep problems in adolescence, and it was expected that the adolescents' eveningness orientation is associated with many sleep-related problems. Students of secondary education (n = 3201; mean = 13.8 ± 1.8 years) filled out a self-report questionnaire containing measures of morningness-eveningness, sleep time (midpoint of sleep, social "jetlag"), sleep length (on schooldays and on weekends), sleep quality, and sleep hygiene as well as questions on electronic screen media use...

OBJECTIVE: This study investigated whether patients with mild to moderately severe dementia or possible Alzheimer's disease (AD) with Mini-Mental State Exam (MMSE) Baseline scores of 10-24 would improve when treated with near-infrared photobiomodulation (PBM) therapy. BACKGROUND: Animal studies have presented the potential of PBM for AD. Dysregulation of the brain's default mode network (DMN) has been associated with AD, presenting the DMN as an identifiable target for PBM...

Feeling unsafe in one's neighborhood is associated with poor health. This relation may be conferred through multiple pathways, including greater psychological distress and health behaviors that are associated with poorer health and perceptions of neighborhood safety. Women and older adults often report feeling less safe in their environments despite having a lower risk of victimization than men and younger adults, and it is unclear whether these differences influence the health-perception relationship. We used the Midlife in the United States study to test whether baseline neighborhood safety perceptions would be associated with chronic health conditions 10 years later, and whether this relation differs by gender, age, and individual and neighborhood SES...

Work-related stress and associated illness and burnout is rising in western society, with now as much as almost a quarter of European and half of USA's employees estimated to be at the point of burnout. Mindfulness meditation, yoga, and physical exercise have all shown beneficial effects for work-related stress and illness. This proof of concept study assessed the feasibility, acceptability, and preliminary effects of the newly developed Mindful2Work training, a combination of physical exercise, restorative yoga, and mindfulness meditations, delivered in six weekly group sessions plus a follow-up session...

Obstructive sleep apnea (OSA) and atrial fibrillation (AF) are common conditions in the adult population and independently associated with increased morbidity and mortality. There is evidence, although not definitive, that OSA independently contributes to AF incidence and recurrence. Full polysomnography is expensive and may not be readily available to diagnose all patients with OSA and AF. Several patients with OSA do not present the classical signs and symptoms of OSA, impairing the accuracy of screening questionnaires for OSA...

REVIEW
Vaishnavi Kundel, Neomi Shah
This article provides the current state of evidence on the socioeconomic impact of portable testing (PT) for sleep apnea. It seems the traditional in-laboratory polysomnography and the newer home-based PT model for sleep apnea diagnosis both have places in sleep medicine diagnostic algorithm. PT would be cost-effective in a selected group of patients as long as certain criteria, discussed in this article, are carefully considered.

PURPOSE: The purpose of this study was to use non-EEG PSG signals to estimate TST in order to diagnose SDB with a greater sensitivity than type 3 device methodology that relies on TRT. METHODS: Movement patterns were obtained from the thoracoabdominal signals of adult PSG recordings (n = 60) in the laboratory and the home. Parameters obtained allowed, with 95% certainty, identification of sleep and wake based on the duration of movements and quiescent time (Qd)...

Research demonstrating that employees who are undermined at work engage in similar behavior at home suggests this connection reflects displaced aggression. In contrast, the present study draws on self-regulation theory to examine the work-home undermining spillover/crossover process. We propose that poor sleep quality transmits the influence of workplace undermining to home undermining per self-regulatory impairment, and exercise moderates this indirect effect per self-regulatory improvement. Using matched data from 118 employees and a member of their household to test our model, results demonstrated that undermining experienced from supervisors increased subjective (i...
