Abnormal metabolite concentrations and amygdala volume in patients with recent-onset posttraumatic stress disorder

Posttraumatic stress disorder (PTSD) is a psychiatric disorder affecting people who are exposed to extraordinary distress events, whose main symptoms are reliving the traumatic event, avoiding trauma-related cues, negative alterations in thinking and feeling, and hyperarousal (American Psychiatric Association, 2013). The lifetime prevalence of PTSD is reported as 2% to 9% (Bisson et al., 2015). Patients with PTSD are at increased risk of suicide, which is as high as 13% in one study of 431 veterans (Jakupcak et al., 2010; Sareen et al., 2007).
