  1. Neurocognitive Consequences of Sleep Deprivation

    Jeffrey S. Durmer, David F. Dinges · 2005 · Seminars in Neurology · 1,473 cites

    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 cites

    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 · 341 cites

    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 · 170 cites

    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 cites

    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.
