2018 Mantua and Simonelli 2019 Tai et al. While several large-scale studies have demonstrated an inverse U-shaped relationship between self-reported sleep duration and cognitive performance (poorer cognitive performance with both shorter and longer sleep durations) ( Richards et al. 2018) and appear to be differently associated with cognitive function ( Bernstein et al. Furthermore, self-report and objective sleep measures-even within the same dimension-have low-to-modest correlations ( Landry et al. This limits the interpretation of results, as self-report measures may be biased by a multitude of contextual and personal factors ( Bliwise and Young 2007 Lauderdale et al. To date, most studies on habitual sleep and cognitive function have relied on retrospective, self-report measures of singular aspects of sleep (typically sleep duration and/or quality) ( Buysse 2014 Scullin and Bliwise 2015 van Langenberg et al. 2017 Knutson and von Schantz 2018 Dong et al. Meanwhile, indicators of poorer sleep health, including short sleep duration, poor sleep quality, and later chronotype (a preference for later sleep timing), have been linked with poorer health outcomes ( Itani et al. 2017), and experiencing little or no problems with sleep or daytime alertness ( Buysse 2014 Allen et al. 2015), good sleep efficiency ( Ohayon et al. Better sleep health is characterized by a regular sleep schedule with an appropriate sleep timing, adequate sleep duration ( Hirshkowitz et al. polysomnography, actigraphy) measures ( Buysse 2014 van Langenberg et al. Sleep health is a multidimensional construct-encompassing the duration, efficiency, timing, and subjective perception of sleep-and may be assessed via self-report (e.g. sleep health ( Buysse 2014 Beattie et al. 2023).Įven in “normal sleepers” (persons without sleep or mental health complaints), there is considerable inter- and intraindividual variability in habitual sleep patterns and sleep need, i.e. However, we still lack knowledge on potential links between cognitive control function and “normal” habitual sleep in the general adult population, as most studies on this topic have focused on clinical, adolescent, or aging populations, and/or have included experimental manipulations of sleep or circadian rhythm ( Scullin and Bliwise 2015 Krause et al. 2021) and associated with negative outcomes across neurological and psychiatric disorders ( Goschke 2013 Snyder et al. Both cognitive control dysfunction and sleep–wake disturbances are transdiagnostic risk factors for developing mental health problems ( McTeague et al. Sleep is vital for brain health, everyday functioning, and quality of life ( Walker and Stickgold 2006 Mignot 2008 Palmer and Alfano 2017 Tahmasian et al. In conclusion, even in “normal sleepers,” relatively poorer sleep health is associated with altered cognitive control processing, possibly reflecting compensatory mechanisms and/or inefficient neural processing.Ĭontinuous performance test, executive function, magnetic resonance imaging, neuropsychology, sleep IntroductionĬognitive control underlies the regulation of thoughts, actions, and emotions and relies on rapid, dynamic communication between widespread brain regions ( Badre 2008 Braver 2012 Diamond 2013 Cole et al. Finally, shorter objective sleep duration was associated with lower BOLD activation with time on task and poorer task performance. Analysis of time-on-task effects showed that, with longer time on task, poorer sleep health was predominantly associated with increased proactive cognitive control activation, indicating recruitment of additional neural resources over time. Most associations were found for reactive cognitive control activation, indicating that poorer sleep health is linked to a “hyper-reactive” brain state. Multiple measures indicating poorer sleep health-including later/more variable sleep timing, later chronotype preference, more insomnia symptoms, and lower sleep efficiency-were associated with stronger and more widespread BOLD activations in fronto-parietal and subcortical brain regions during cognitive control processing (adjusted for age, sex, education, and fMRI task performance). Sleep health was assessed in the week before MRI scanning, using both objective (actigraphy) and self-report measures. BOLD fMRI data were acquired from 81 healthy adults with normal sleep (41 females, age 20.96–39.58 years) during a test of cognitive control (Not-X-CPT). This study investigated how proactive and reactive cognitive control processing in the brain was associated with habitual sleep health.
