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)
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)
