  1. Neurocognitive Consequences of Sleep Deprivation

    Jeffrey S. Durmer, David F. Dinges · 2005 · Seminars in Neurology · 1,474 citations

    Deficits in daytime performance due to sleep loss are experienced universally and associated with a significant social, financial, and human cost. Microsleeps, sleep attacks, and lapses in cognition increase with sleep loss as a function of state instability. Sleep deprivation studies repeatedly show a variable (negative) impact on mood, cognitive performance, and motor function due to an increasing sleep propensity and destabilization of the wake state. Specific neurocognitive domains including executive attention, working memory, and divergent higher cognitive functions are particularly vulnerable to sleep loss. In humans, functional metabolic and neurophysiological studies demonstrate tha

  3. Sleep deprivation: Impact on cognitive performance

    Paula Alhola, Päivi Polo‐Kantola · 2007 · Neuropsychiatric Disease and Treatment · 867 citations

    Today, prolonged wakefulness is a widespread phenomenon. Nevertheless, in the field of sleep and wakefulness, several unanswered questions remain. Prolonged wakefulness can be due to acute total sleep deprivation (SD) or to chronic partial sleep restriction. Although the latter is more common in everyday life, the effects of total SD have been examined more thoroughly. Both total and partial SD induce adverse changes in cognitive performance. First and foremost, total SD impairs attention and working memory, but it also affects other functions, such as long-term memory and decision-making. Partial SD is found to influence attention, especially vigilance. Studies on its effects on more demand

  5. Effects of Partial and Acute Total Sleep Deprivation on Performance across Cognitive Domains, Individuals and Circadian Phase

    June Chi-Yan Lo, John A. Groeger, Nayantara Santhi, et al. · 2012 · PLoS ONE · 342 citations

    BACKGROUND: Cognitive performance deteriorates during extended wakefulness and circadian phase misalignment, and some individuals are more affected than others. Whether performance is affected similarly across cognitive domains, or whether cognitive processes involving Executive Functions are more sensitive to sleep and circadian misalignment than Alertness and Sustained Attention, is a matter of debate. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a 2 × 12-day laboratory protocol to characterize the interaction of repeated partial and acute total sleep deprivation and circadian phase on performance across seven cognitive domains in 36 individuals (18 males; mean ± SD of age = 27.6 ± 4.0 yea

  7. The consequences of sleep deprivation on cognitive performance

    Mohammad Khan, Hamdan H. Al-Jahdali · 2023 · Neurosciences · 177 citations

    Although not fully understood, sleep is accepted as a vital and organized sequence of events that follows a regular cyclic program each night to ensure the human body can perform at its optimum. A lack of sleep, or sleep deprivation (SD), is a widespread phenomenon that can induce adverse changes in cognitive performance. This review focused on the biological explanation as well as the research investigating the numerous effects that SD can have on cognition. A reduction in sleep does not occur independently of the effects on memory, attention, alertness, judgment, decision-making, and overall cognitive abilities in the brain, resulting in decreased function and impaired cognitive performanc

  8. The effects of sleep deprivation on divergent thinking and attention processes

    Frank Wimmer, Robert F Hoffmann, Richard A. Bonato, et al. · 1992 · Journal of Sleep Research · 150 citations

    Twelve male undergraduate students were deprived of sleep for one night and were tested with a series of cognitive tasks. Their performance was compared to the performance of thirteen control subjects. Two hourly tasks and three occasional tasks were administered in order to examine cognitive performance following sleep loss. In an attempt to replicate the findings of Horne (1988a), the figural form of the Torrance Tests of Creative Thinking was administered. To explore the effects of short-term sleep deprivation on attention, the following tasks were also administered: a working memory task, a trail-making task, a vowel/consonant discrimination task, and a letter recognition task.

  9. Effects of Sleep Deprivation on the Cognitive Performance of Nurses Working in Shift

    Deepalakshmi Kaliyaperumal · 2017 · JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH · 123 citations

    INTRODUCTION: Sleep deprivation and altered circadian rhythm affects the cognitive performance of an individual. Quality of sleep is compromised in those who are frequently involved in extended working hours and shift work which is found to be more common among nurses. Cognitive impairment leads to fatigability, decline in attention and efficiency in their workplace which puts their health and patients' health at risk. AIM: To find out the prevalence of sleep deprivation and its impact on cognition among shift working nurses. MATERIALS AND METHODS: Sleep deprivation among 97 female and three male healthy nurses of age 20-50 years was assessed by Epworth sleepiness scale (ESS). Cognition was

  10. The effects of chronic sleep reduction on the performance of cognitive tasks sensitive to sleep deprivation

    Mark Blagrove, Carol Alexander, James A. Horne · 1995 · Applied Cognitive Psychology · 88 citations

    In four sleep loss experiments we aimed, first, to compare performance during long‐term sleep reduction with performance during short‐term total sleep deprivation, and second, to measure the effects of both methods of sleep loss on ability to ignore distracting irrelevant stimuli, using a finding embedded figures test (FEFT). Logical reasoning, auditory vigilance and finding embedded figures tasks were shown to be significantly sensitive to one night's sleep deprivation. However, in one sleep reduction study subjects reduced to a mean of 5.2 hours sleep per night for 4 weeks showed no performance deficits on logical reasoning. In a second sleep reduction study subjects reduced to a mean of 4

  11. The Role of Sleep and the Effects of Sleep Loss on Cognitive, Affective, and Behavioral Processes

    Anna Hyndych, R. El-Abassi, E. Mader · 2025 · Cureus · 84 citations

    Sleep is essential for various cognitive, affective, and behavioral processes, including attention, memory, executive function, emotional regulation, and interpersonal interactions. Sleep disruptions undermine these functions, resulting in measurable impairments in daily activities, occupational performance, and public safety. Adequate sleep supports sustained vigilance and concentration, whereas sleep deprivation is associated with attentional lapses, diminished cognitive control, and impaired sensory processing. Memory consolidation, which depends on both non-rapid eye movement (NREM) and rapid eye movement (REM) sleep, is particularly susceptible to disruption by sleep loss. Executive fun

  12. Sleep Deprivation and Sustained Attention Performance: Integrating Mathematical and Cognitive Modeling

    Glenn Gunzelmann, Joshua B. Gross, Kevin A. Gluck, et al. · 2009 · Cognitive Science · 83 citations

    A long history of research has revealed many neurophysiological changes and concomitant behavioral impacts of sleep deprivation, sleep restriction, and circadian rhythms. Little research, however, has been conducted in the area of computational cognitive modeling to understand the information processing mechanisms through which neurobehavioral factors operate to produce degradations in human performance. Our approach to understanding this relationship is to link predictions of overall cognitive functioning, or alertness, from existing biomathematical models to information processing parameters in a cognitive architecture, leveraging the strengths from each to develop a more comprehensive exp

  13. Sleep deprivation effects on basic cognitive processes: which components of attention, working memory, and executive functions are more susceptible to the lack of sleep?

    Aída García, J. del Angel, Jorge Borrani, et al. · 2020 · Sleep Science · 57 citations

    ABSTRACT Introduction: Sleep deprived people have difficulties to perform daily activities. Their performance depends on three basic cognitive processes: attention, working memory, and executive functions. Objectives: The aim of this study was to identify which speci.c components of these cognitive processes are more susceptible to a 24-h sleep deprivation period. Material and Methods: Participants were 23 undergraduate students assigned to one of two groups: a control group (n=11, age=18.73±1.62 years) and a sleep deprivation group (n=12, age=18.08±1.16 years). After sleeping freely, control group participants performed a continuous performance task to evaluate the components of attention,

  17. Effects of Caffeine Intake on Cognitive Performance Related to Total Sleep Deprivation and Time on Task: A Randomized Cross-Over Double-Blind Study

    M. Quiquempoix, F. Sauvet, Mégane Erblang, et al. · 2022 · Nature and Science of Sleep · 16 citations

    Introduction It is widely admitted that both total sleep deprivation (TSD) and extended task engagement (Time-On-Task, TOT) induce a cognitive fatigue state in healthy subjects. Even if EEG theta activity and adenosine both increase with cognitive fatigue, it remains unclear if these modifications are common mechanisms for both sustained attention and executive processes. Methods We performed a double-blind counter-balanced (placebo (PCBO) and caffeine (CAF) - 2×2.5 mg/kg/24 h)) study on 24 healthy subjects (33.7 ± 5.9 y). Subjects participated in an experimental protocol including an habituation/training day followed by a baseline day (D0 and D1) and a total sleep deprivation (TSD) day begi

  18. Sleep Pattern Interference in the Cognitive Performance of Lusitano Horses

    Â. P. Barbosa, T. M. Oliveira, P. Trindade, et al. · 2024 · Animals : an Open Access Journal from MDPI · 12 citations

    Simple Summary Little is known about how incomplete sleep affects a horse’s memorization. Like most mammals, horses need sleep to fully function, with differences in the total sleep time needed. The literature shows that horses need about three to four hours divided between two phases: the REM (rapid eye movement) phase and the NREM (non-rapid eye movement) phase. The aim of this study was to better understand how interference with the REM phase can affect the memory skill of horses. For this study, 10 horses were filmed in their stall to characterize their sleep patterns for 48 h. Afterwards, horses that experienced REM sleep interference and horses that did not experience REM sleep interfe

  19. Cognitive performance during exposure to moderate normobaric hypoxia after sleep restriction: relationship to physiological and stress biomarkers.

    P. Fabries, A. Pontiggia, Ulysse Comte, et al. · 2024 · Physiology & behavior · 6 citations

    INTRODUCTION Exposure to moderate levels of simulated hypoxia has subtle cognitive effects relative to ground level, in healthy individuals. However, there are few data on the cognitive consequences of the combination of hypoxia and partial sleep deprivation, which is a classic military or civilian operational context. In this study, we tested the hypothesis that exposure to moderate hypoxia while sleep-restricted impairs several domains of cognition, and we also assessed physiological parameters and salivary concentrations of cortisol and alpha-amylase. METHOD Seventeen healthy males completed two sessions of cognitive tests (sustained attention using the PVT psychomotor vigilance task an

  21. Intelligence predicts better cognitive performance after normal sleep but larger vulnerability to sleep deprivation

    L. Balter, T. Sundelin, B. Holding, et al. · 2022 · Journal of Sleep Research · 2 citations

    Fluid intelligence is seen as a beneficial attribute, protecting against stress and ill‐health. Whether intelligence provides resilience to the cognitive effects of insufficient sleep was tested in the current pre‐registered experimental study. Participants (N = 182) completed the Raven's test (measuring fluid intelligence) and a normal night of sleep or a night of total sleep deprivation. Sleepiness and four cognitive tests were completed at 22:30 hours (baseline), and the following day after sleep manipulation. At baseline, higher fluid intelligence was associated with faster and more accurate arithmetic calculations, and better episodic memory, but not with spatial working memory, simple

  22. Memory impairments observed after a half night sleep restriction are not mediated by working memory, attention, or inhibitory control mechanisms.

    Pim R. A. Heckman, R. Havekes, Arjan Blokland · 2025 · Neurobiology of learning and memory · 2 citations

    Sleep restriction is a growing issue in our modern society and thus it is crucial to uncover its neurocognitive consequences. Especially declarative memory is negatively affected by sleep loss due to its critical dependence on the hippocampus, a brain area known to be susceptible to sleep loss. Studies have shown that even a half night sleep restriction is sufficient to induce impairments in a range of hippocampus-dependent forms of memory. Nevertheless, memory performance is, at least to some extent, dependent on other cognitive functions. The aim of the current study was to reveal whether memory deficits observed after one night sleep deprivation, as observed in animal studies, translate t
