Neurocircuitry models of panic disorder have hypothesized that the panic attack itself stems from loci in the brainstem including the ascending reticular system and respiratory and cardiovascular control centers. Voxel-based morphometry with acobian modulation was used to examine gray matter volume changes in 10 panic disorder patients and 23 healthy controls. The panic disorder patients had a relatively increased gray matter volume in the midbrain and rostral pons of the brainstem. Increased ventral hippocampal and decreased regional prefrontal cortex volumes were also noted at a lower significance threshold. This finding has implications for pathophysiologic models of panic disorder, and provides structural evidence for the role of the brainstem in neurocircuitry models of panic disorder

The primary objective of this study was to examine unresolved trauma as assessed by the Adult Attachment Interview and current psychiatric symptoms, focusing on posttraumatic stress disorder (PTSD) and dissociation, in a group of adult female childhood abuse survivors. The authors examined psychiatric symptoms and attachment representations in a group with (n = 30) and without (n = 30) abuse-related PTSD. The findings revealed that unresolved trauma carried a 7.5-fold increase in the likelihood of being diagnosed with PTSD and was most strongly associated with PTSD avoidant symptoms rather than dissociative symptoms. The utility of a PTSD framework for understanding unresolved trauma and the role of intentional avoidance of trauma cues in the maintenance of traumatized states of mind are discussed

The immediate and long-term consequences of children's exposure to maltreatment and other traumatic experiences are multifaceted. Emotional abuse and neglect, sexual abuse, and physical abuse, as well as witnessing domestic violence, ethnic cleansing, or war, can interfere with the development of a secure attachment within the caregiving system. Complex trauma exposure results in a loss of core capacities for self-regulation and interpersonal relatedness. Children exposed to complex trauma often experience lifelong problems that place them at risk for additional trauma exposure and cumulative impairment (e.g., psychiatric and addictive disorders; chronic medical illness; legal, vocational, and family problems). These problems may extend from childhood through adolescence and into adulthood. This article describes a new theoretical framework for understanding complex trauma in children, explains how to apply the new framework to assessment of traumatized children and families, and discusses intervention models designed specifically for traumatized children and their families.

(from the journal abstract) Women who have PTSD related to childhood abuse have significant deficits in the areas of emotion regulation and interpersonal skills. These problems are associated with impaired functioning in social, work, and home life. In addition, there is substantial clinical concern that limited emotion-regulation skills puts this population at risk for early dropout and symptom exacerbation in treatment focusing on emotional processing of traumatic memories. Skills Training in Affective and Interpersonal Regulation plus Modified Prolonged Exposure (STAIR/MPE) is an evidence-based, 2-phase cognitive behavioral treatment designed to address these concerns. Specifically, this treatment targets PTSD symptoms, emotion-regulation deficits, and interpersonal difficulties. The purpose of this article is to describe the rationale for and clinical application of STAIR/MPE, detailing the essential clinical components and presenting relevant case examples.

This study sought to determine the relative contribution of problems in emotion regulation and interpersonal functioning compared to PTSD symptoms in predicting functional impairment among women with childhood abuse histories. One hundred sixty-four treatment-seeking women completed measures of emotion regulation, interpersonal problems, PTSD symptoms, and social adjustment. Severity of PTSD symptoms was a significant predictor of functional impairment. In addition, after controlling for the effects of PTSD symptomatology, emotion regulation and interpersonal problems were both significant predictors and together made contributions to functional impairment equal to that of PTSD symptoms. These data indicate that emotion regulation and interpersonal problems play an important role in functional impairment among women with a history of childhood abuse. These factors should be taken into account in treatment planning to ensure successful rehabilitation from the long-term effects of chronic childhood trauma. (journal abstract)

Functional magnetic resonance imaging in association with an instructed fear/anticipatory anxiety paradigm was used to explore sex differences in the human fear response. During anticipation of mild electrodermal stimulation, women, as compared with men, demonstrated increased activity in the subgenual anterior cingulate cortex and functionally related regions of the insula and brainstem. The subgenual anterior cingulate cortex is a region critical for emotional control implicated in the pathogenesis of psychiatric disease. Present findings suggest a contributory neural substrate for the greater susceptibility of women to anxiety and affective disorders, and emphasize the importance of considering participant sex when designing and interpreting functional neuroimaging studies

BACKGROUND: Previous neuroimaging studies have demonstrated exaggerated amygdala responses to negative stimuli in posttraumatic stress disorder (PTSD). The time course of this amygdala response is largely unstudied and is relevant to questions of habituation and sensitization in PTSD exposure therapy. METHODS: We applied blood oxygen level dependent functional magnetic resonance imaging and statistical parametric mapping to study amygdala responses to trauma-related and nontrauma-related emotional words in sexual/physical abuse PTSD and normal control subjects. We examined the time course of this response by separate analysis of early and late epochs. RESULTS: PTSD versus normal control subjects have a relatively increased initial amygdala response to trauma-related negative, but not nontrauma-related negative, versus neutral stimuli. Patients also fail to show the normal patterns of sensitization and habituation to different categories of negative stimuli. These findings correlate with measured PTSD symptom severity. CONCLUSIONS: Our results demonstrate differential time courses and specificity of amygdala response to emotional and control stimuli in PTSD and normal control subjects. This has implications for pathophysiologic models of PTSD and treatment response. The results also extend previous neuroimaging studies demonstrating relatively increased amygdala response in PTSD and expand these results to a largely female patient population probed with emotionally valenced words

This study examined the related contributions of the therapeutic alliance and negative mood regulation to the outcome of a 2-phase treatment for childhood abuse-related posttraumatic stress disorder (PTSD). Phase 1 focused on stabilization and preparatory skills building, whereas Phase 2 was comprised primarily of imaginal exposure to traumatic memories. Hierarchical regression analyses indicated the strength of the therapeutic alliance established early in treatment reliably predicted improvement in PTSD symptoms at posttreatment. Furthermore, this relationship was mediated by participants' improved capacity to regulate negative mood states in the context of Phase 2 exposure therapy. In the treatment of childhood abuse-related PTSD, the therapeutic alliance and the mediating influence of emotion regulation capacity appear to have significant roles in successful outcome.
