“…Hence, failure to suppress an unwanted memory when sleep deprived allows both the content and affective tone of that memory (represented by hippocampus and amygdala, respectively [2]) to intrude into consciousness, prompting a deterioration of emotional well-being. Supporting this view, whereas in well-rested people repeatedly suppressing thoughts about unpleasant images reduces subjective and psychophysiological arousal responses to those images, no such salutary benefit of memory suppression is observed in sleep-deprived individuals [7].…”

“…Recent work has demonstrated that sleep-deprived individuals are ineffective at suppressing unwanted thoughts [7]. Whereas memory suppression reduces future thought intrusions in well-rested people, sleep-deprived individuals fail to exhibit the same intrusion-reducing benefit of effective memory control.…”

“… 14 For example, one previous event-related potentials (ERP) study found that poor sleep affects the speed to inhibit a motor response as well as the intensity of pre-motor inhibitory processes and task-relevant information processing, 15 while a more recent study found that sleep deprivation impairs memory control with sleep-deprived participants showing more unsuccessful suppression of intrusions of emotionally negative and neutral scenes than rested participants. 16 However, the effects of both total and partial sleep deprivation on inhibition control are not consistent. In TSD experiments, some studies have found that inhibition control is significantly diminished from baseline after TSD, 17–22 while others found no significant changes.…”

Purpose Sleep loss impairs a range of neurobehavioral functions, particularly vigilant attention and arousal. However, the detrimental effects of sleep deprivation on inhibition control and its relationship to vigilant attention impairments remain unclear. This study examined the extent to which vigilant attention deficits contribute to inhibition control performance after one night of total sleep deprivation (TSD) and two nights of partial sleep restriction (PSR). Participants and Methods We analyzed data from N = 49 participants in a one-night of TSD experiment, N=16 participants in a control experiment without sleep loss, and N = 16 participants in a two-nights of PSR experiment (time in bed, TIB = 6 h for each night). Throughout waking periods in each condition, participants completed the psychomotor vigilance test (PVT), which measures vigilant attention, and the Go/No-Go task, which measures inhibition control. Results After TSD and PSR, participants displayed significantly slower reaction times (RT) and more lapses in PVT performance, as well as slower Go RT and more errors of omission during the Go/No-Go task. PVT deficits accounted for 18.0% of the change in Go RT and 12.4% of the change in errors of omission in the TSD study, and 23.7% of the change in Go RT and 20.3% of the change in errors of omission in the PSR study. Conclusion Both TSD and PSR impaired inhibition control during the Go/No-Go task, which can be partly accounted for by vigilant attention deficits during the PVT. These findings support the key role of vigilant attention in maintaining overall neurobehavioral function after sleep loss.

“…Sleep disturbances escalate just before manic and depressive relapse in BD, and worsen during these episodes. 23 There is strong evidence detailing the negative effects of sleep disturbance on many aspects of cognition in healthy individuals 24 , including fragmented memory loss 25 and impaired suppression of unwanted thoughts 26 . Recently, evidence has emerged to suggest an association between sleep disturbance and cognitive impairment in mood disorders.…”

Background: Cognitive impairment experienced by people with bipolar disorders (BD) or major depressive disorder (MDD) is associated with impaired psychosocial function and poorer quality of life. Sleep disturbance is another core symptom of mood disorders which may be associated with, and perhaps worsen, cognitive impairments. The aim of this systematic review was to critically assess the relationship between sleep disturbance and cognitive impairment in mood disorders. Methods: In this systematic review, relevant studies which examined sleep disturbance and cognitive function in people with mood disorders were identified using electronic database searches of PsychINFO, MEDLINE, Embase and Web of Science. Findings: Fifteen studies were included; nine investigated people with BD, five investigated people with MDD, and one included both people with MDD and people with BD. One study was an intervention for sleep disturbance and the remaining fourteen studies used either a longitudinal or cross-sectional observational design. Eleven studies reported a significant association between subjectively measured sleep disturbance and cognitive impairment in people with MDD or BD after adjusting for demographic and clinical covariates, whereas no such association was found in healthy participants. Two studies reported a significant association between objectively measured sleep abnormalities and cognitive impairment in mood disorders. One study of cognitive behavioural therapy for insomnia modified for BD (CBTI-BD) found an association between improvements in sleep and cognitive performance in BD. Interpretation: There is preliminary evidence to suggest a significant association between sleep disturbance and cognitive impairment in mood disorders. These findings suggest that identifying and treating sleep disturbance may be important when addressing cognitive impairment in MDD and BD.
