The present study evaluated the independent and cumulative effects of recent life stress, previous trauma, and recent trauma exposure on salivary cortisol levels among school-aged children. Sixty-eight children (mean age=10.7 years) reported their exposure to life stressors and traumatic events in the 12 months preceding the study. Children and their(More)
BACKGROUND Recent studies have reported a high comorbidity between posttraumatic stress disorder (PTSD) and psychotic symptoms, and it has been hypothesized that PTSD with comorbid psychosis is a severe form of PTSD. Few studies have examined the neurobiology of PTSD with comorbid psychosis. If PTSD with secondary psychotic symptoms (PTSD-SP) is a severe(More)
One of the most exciting developments to emerge from the field in the past 20 years is the increasing attention to neurobiological responses to violence and trauma exposure. Although researchers have yet to identify a consensual pattern of neurobiological response to violence and trauma exposure, it does appear that some type of alteration in the(More)
Studies show high comorbidity between post-traumatic stress disorder and psychotic symptoms. Despite this fact, there has been only one published study of the neurobiology of this enigmatic disorder. This preliminary study examines the relationship between psychotic symptoms in post-traumatic stress disorder (PTSD) and schizophrenia by measuring smooth(More)
In event-related potential (ERP) studies of cognitive processes, the electrophysiological responses are typically contrasted between experimental conditions that are taken to represent discrete categories (e.g. attended vs. unattended stimuli, or real vs. nonsense words). Because categorical variation is less powerful than continuous or parametric(More)
Given the alarming frequency and severity of trauma exposure among children, identifying contextual and biologic factors that increase risk for symptomatic responses to trauma is an essential step toward preventing psychopathology. Basal functioning of the hypothalamic pituitary adrenal axis was evaluated to determine its role in relations between trauma(More)
