Association Between Sleep Reactivity, Pre-Sleep Arousal State, and Neuroendocrine Hormones in Patients with Chronic Insomnia Disorder

The purpose of this study was to look into the relationship between pre-sleep arousal state, sleep reactivity, and serum levels of neuroendocrine hormones (cortisol, copeptin, and corticotropin-releasing hormone) in patients with chronic insomnia disorders (CID), and whether the effects of sleep reactivity and pre-sleep arousal on insomnia are related to the levels of these neuroendocrine hormones.
