A coordinate-based meta-analysis comparing brain activation between ADHD and total sleep deprivation.

Sleep disruption is common in attention-deficit-hyperactivity-disorder (ADHD). Likewise, deficits in attention are a hallmark of sleep deprivation in healthy individuals. Whether ADHD and sleep deprivation modulate common, or disparate, neural systems is unknown. No study has yet utilized fMRI to investigate sleep loss in ADHD. We address this gap by performing a novel meta-analysis to compare patterns of fMRI activation during sleep deprivation and ADHD.

Roles of sleep deprivation in cardiovascular dysfunctions.

It is widely recognized that inadequate sleep is associated with multiple acute and chronic diseases and results in increased mortality and morbidity for cardiovascular diseases. In recent years, there has been increasing interest in sleep related investigations. Emerging evidence indicates that sleep deprivation changes the biological phenotypes of DNA, RNA and protein levels, but the underlying mechanisms are not clear. We summarized the current research on the detrimental roles of sleep deprivation on th...

Dissociable effects of sleep deprivation on functional connectivity in the dorsal and ventral default mode networks.

To examine changes in functional connectivity of the default mode network (DMN) that are induced by sleep deprivation, and to identify individual differences that contribute to the vulnerability of the brain's response to sleep deprivation.

Effect of sleep deprivation on hearing levels in rats.

To our knowledge, the influence of sleep deprivation on hearing levels has yet to be assessed in animals. Therefore, we evaluated whether auditory function was affected by sleep deprivation in rats.

Sleep Deprivation Enhances Inter-Stimulus Interval Effect on Vigilant Attention Performance.

Sleep deprivation significantly reduces the ability to maintain a consistent alertness level and impairs vigilant attention. Previous studies have shown that longer inter-stimulus intervals (ISI) are associated with faster reaction times (RT) on the Psychomotor Vigilance Test (PVT). However, whether and how sleep deprivation interacts with this ISI effect remains unclear.

Neuroendocrine aspects of improving sleep in epilepsy.

Sleep plays an intricate role in epilepsy and can affect the frequency and occurrence of seizures. With nearly 35% of U.S. adults failing to obtain the recommended 7 h of sleep every night, understanding the complex relationship between sleep and epilepsy is of utmost relevance. Sleep deprivation is a common trigger of seizures in many persons with epilepsy and sleep patterns play a role in the occurrence of seizures. Some patients have their first seizure or repeated seizures after an "all-nighter" at co...

Sleep deprivation differentially affects subcomponents of cognitive control.

Although sleep deprivation has long been known to negatively affect cognitive performance, the exact mechanisms through which it acts and what cognitive domains are impacted most is still disputed. The current study provides a theory-driven approach to examine and explain the detrimental effects of sleep loss with a focus on attention and cognitive control.

Chronic Sleep Deprivation in Mouse Pups by Means of Gentle Handling.

Sleep is critical for proper development and neural plasticity. Moreover, abnormal sleep patterns are characteristic of many neurodevelopmental disorders. Studying how chronic sleep restriction during development can affect adult behavior may add to our understanding of the emergence of behavioral symptoms of neurodevelopmental disorders. While there are many methods that can be used to restrict sleep in rodents including forced locomotion, constant disruption, presentation of an aversive stimulus, or elect...

Augmentation of Pharmacotherapy by Sleep Deprivation with Sleep Phase Advance in Treatment-Resistant Depression.

The aim was to assess the efficacy of total sleep deprivation (TSD) with sleep phase advance (SPA) in treatment-resistant depression (TRD) and associated biochemical factors.

The wake maintenance zone shows task dependent changes in cognitive function following one night without sleep.

The interaction between homeostatic sleep pressure and circadian timing modulates the impact of sleep deprivation on cognition. We aimed to investigate how this interaction affects different cognitive functions.

The relationship between naturalistic sleep variation and error monitoring in young adults: An event-related potential (ERP) study.

Sleep deprivation studies have highlighted the importance of adequate sleep for optimal daytime functioning. However, there is limited research exploring whether variations in natural sleep patterns produce similar difficulties to those seen in sleep deprivation studies. The aim of the current study was to explore whether naturalistic reductions in sleep duration and/or sleep quality were associated with behavioural and electrophysiological measures of cognitive control. Sixty undergraduate students were as...

REM deprivation but not sleep fragmentation produces a sex-specific impairment in extinction.

REM sleep is essential for learning and memory processes, particularly emotional learning. Manipulations of REM sleep impair learning and memory and sleep architecture is often altered following a learning experience; for example, short term REM deprivation immediately after fear conditioning results in impaired extinction. In light of research demonstrating sex-dependent differences in fear conditioning as well as differences in sleep architecture, the present study investigated the effects of short term R...

Sleep spindles in adolescence: a comparison across sleep restriction and sleep extension.

The tendency for adolescents to have restricted sleep has been examined in numerous studies; however, the impact of sleep restriction on adolescents' neural activity during sleep (measured by electroencephalography (EEG)) is less extensively researched, particularly regarding sleep spindles.

Regional cerebral hypoperfusion after acute sleep deprivation: A STROBE-compliant study of arterial spin labeling fMRI.

Previous neuroimaging studies have shown that functional changes occur after acute sleep deprivation, which suggest detrimental effects of a lack of sleep on the intrinsic functional architecture of the brain. We aimed to identify regional resting perfusion changes in subjects with acute sleep deprivation.Thirty-three healthy subjects with habitual good sleep participated in 36 hours (2 days and 1 night) of sleep deprivation and then underwent the attention network test and pseudo-continuous arterial spin...

Cardiovascular regulation and body temperature: evidence from a nap vs. sleep deprivation randomized controlled trial.

In this study we set out to understand is sleep fragmentation affects the cardiovascular regulation and circadian variability of core body temperature more or less than sleep deprivation. 50 healthy men (age 29.0+/-3.1 years; BMI 24.3+/-2.1 kg/m(2)) participated in a 3-day study that included one adaptative night and one experimental night involving randomization to: sleep deprivation (SD) and sleep fragmentation (SF). The evaluation included hemodynamic parameters, measures of the spectral analysis of hear...

Sleep debt at the community level: impact of age, sex, race/ethnicity and health.

Insufficient sleep has become recognized as a pervasive problem in modern society. Sleep debt is a novel measure of sleep adequacy that may be useful in describing those at risk for inadequate sleep. Our objective was to investigate factors that may be associated with sleep debt at the population level, as well as build upon previous data that showed that minority groups may be more likely to have sleep debt.

Sleep disturbance and pain: a tale of two common problems.

Chronic pain has been associated with sleep disturbances in a bidirectional manner, with pain disrupting sleep, and sleep deprivation or disturbance increasing pain. This conventional view began to be reassessed with data from longitudinal and micro-longitudinal studies investigating the causal relationship. In this review, we examine the current thinking on the temporal associations between sleep and pain, focusing on studies that considered whether sleep disturbances could predispose individuals to pain c...

Sleep deprivation-induced pre- and postsynaptic modulation of orexin neurons.

Sleep/wake states are controlled by sleep- and wake-promoting systems, and transitions between states are thought to be regulated by their reciprocal inhibition and homeostatic sleep need. Orexin neurons are known to promote wake maintenance and stabilize the sleep/wake switch. Thus, we asked whether orexin neurons are modulated by homeostatic sleep need. Rats were sleep deprived or left undisturbed to rest for 6 hours, then acute brain slices were generated for patch clamp recordings. We found that sleep d...

The Neurobiological Basis of Sleep and Sleep Disorders.

The functions of sleep remain a mystery. Yet they must be important since sleep is highly conserved, and its chronic disruption is associated with various metabolic, psychiatric, and neurodegenerative disorders. This review will cover our evolving understanding of the mechanisms by which sleep is controlled and the complex relationship between sleep and disease states.

Sustained vigilance is negatively impacted by mild and acute sleep loss reflected by reduced capacity for decision making, motor preparation and execution.

The behavioural and cognitive consequences of severe sleep deprivation are well understood. Surprisingly, relatively little is known about the neural correlates of mild and acute sleep restriction on tasks that require sustained vigilance for prolonged periods of time during the day.

Heart Rate Variability Rebound Following Exposure to Persistent and Repetitive Sleep Restriction.

While it is well established that slow wave sleep electroencephalography (EEG) rebounds following sleep deprivation, very little research has investigated autonomic nervous system recovery. We examined heart rate variability (HRV) and cardiovagal baroreflex sensitivity (BRS) during 4 blocks of repetitive sleep restriction and sequential nights of recovery sleep. Twenty-one healthy participants completed the 22-day in-hospital protocol. Following 3 nights of 8h sleep, they were assigned to a repetitive sleep...

Sleep disturbances after deployment: National Guard soldiers' experiences and strategies.

Sleep deprivation and sleep disturbance are pervasive among military personnel during and after combat deployment. However, occupational and other constraints often influence military workers to decline behavioral health services and prescription pharmaceutical sleep aids. This article, drawing on ethnographic interviews with National Guard veterans of combat deployment, demonstrates that soldiers with sleep disturbance frequently manage symptoms without medical supervision and by using ad hoc methods inclu...

Sleep Disorders are a Prevalent and Serious Comorbidity in Dry Eye.

Sleep is an essential life habit and closely associated with lifespan, diabetes, hypertension, and mental health. Sleep disorders are a prominent, but overlooked problem in patients with dry eye disease (DED), characterized by a poor sleep index, short sleep duration, long sleep latency, and poor subjective sleep. DED and sleep disorders are more prevalent in women than men. Moreover, sleep quality in DED is worse than in other eye diseases, including glaucoma, retinal diseases, cataract, and allergic and c...

Combining trait and state model systems of psychosis: The effect of sleep deprivation on cognitive functions in schizotypal individuals.

Model systems of psychosis play an important role in pathophysiology and drug development research. Schizotypal individuals display similar cognitive impairments as schizophrenia patients in several domains. Therefore, schizotypy may be interpreted as a trait model system of psychosis. In addition, experimentally controlled sleep deprivation is a putative state psychosis model that evokes subclinical psychosis-like states. We aimed to further validate these model systems by examining them in relation to cen...
