【 摘 要 】

Sleep is an intrinsic condition of life. Although “why do we sleep” is still an elusive question, inthe last decade several studies have shown that sleep plays a key role in memory and emotionalprocessing. Yet, the specific mechanisms underlying sleep-related memory and emotional processesremain partially unknown, and studies often report contradictory results (Cordi and Rasch, 2020).From a psychopathology point of view, literature is showing how people suffering from sleepproblems, such as in insomnia, are often characterized by cognitive dysfunctions and emotiondysregulation (Jansson-Fröjmark et al., 2016; Cellini, 2017; Ballesio et al., 2018). Neuroimagingstudies are also supporting this view. As recently summarized by Schiel et al. (2020), insomniais related to altered amygdala reactivity, morphometry, and adaptation. Moreover, insomnia isassociated with aberrant connectivity in the default mode network, alterations in the saliencenetwork associated with hyperarousal, maladaptive emotion regulation, and disturbed integrationof emotional states. Considering that the ability to adaptively regulate emotions is crucial forhealthy functioning, the dysregulation of negative affect circuitry associated or due to insomnia maymediate the impact of insomnia on psychopathology. Indeed, sleep difficulties are often associatedwith other mental disorders and may be considered a transdiagnostic risk factor (Fairholme et al.,2013), although the role of the mediating factors still needs to be clarified.
