“…It is possible that the need for acute antidepressant drug treatment and sleep problems that persist following remission are clinical markers of a biologically distinct depressive subtype that is characterized by hyperarousal and a recurrent or chronic course. Hyperarousal is a state of abnormally high alertness in the sleep environment characterized by the failure to appropriately modulate the metabolic activity of the prefrontal cortex (Nofzinger et al 2004) and the brain's electrical activity during sleep (Krystal et al 2002;Merica et al 1998;Perlis et al 2001), by the sympathetic cardiovascular response (Bonnet and Arand 1997), hypercortisolemia (Rodenbeck et al 2002;Vgontzas et al 2001), and increased systemic metabolism (Bonnet and Arand 1995). Hyperarousal and, more broadly, disruption of the circadian cycle, appears to play a particularly important role in depressed women (Armitage 2007); it may interfere with mood regulation and thus precipitate new depressive episodes in these patients.…”

“…There is some evidence to suggest that there is a bidirectional interaction between sleep and stress physiology [44,45]. A review of the interaction between stress and sleep suggests that hyperactivity of the hypothalamo-pituitary adrenal axis can result in sleep fragmentation, decreased slow wave sleep and reduced total sleep time [46].…”

“…Hypothalamic-pituitary-adrenal (HPA) axis activity plays a role in hypertension and diabetes development 9,10 . However, data suggesting that HPA hormone levels are higher in insomnia are still inconclusive 11,12,13 .…”
