Reduced heart rate variability during sleep: a candidate PTSD biomarker with implications for health risk: Commentary on Ulmer et al., “Posttraumatic stress disorder diagnosis is associated with reduced parasympathetic activity during sleep in US veterans and military service members of the Iraq and Afghanistan wars”

[摘要] Since the initial designation of posttraumatic stress disorder (PTSD) in the DSM-III, heightened arousal has been a core construct operationalized by symptom cluster criteria that have included insomnia symptoms, vigilant behaviors, poor concentration (perhaps as a consequence of the prior two symptoms), irritability, and startle reactivity [1]. The conceptualization underlying this cluster criterion has invoked that increasing arousal is an adaptive response to threat that can persist maladaptively after a period of trauma exposure, manifesting in the aforementioned symptoms. The most consistent validation of this construct has come from numerous demonstrations of conditioned reactivity to trauma-related stimuli (including stimuli with more generalized...
