Neural correlates of response bias: Larger hippocampal volume correlates with symptom aggravation in combat-related posttraumatic stress disorder
Posttraumatic stress disorder (PTSD) is a complex and debilitating psychiatric disorder, caused by exposure to traumatic events. PTSD is characterized by hyperarousal, avoidance, and re-experiencing, including intrusive memories and sensory flashbacks of the traumatic event (American Psychiatric Association, 2013). Diagnosis of PTSD is made by a clinical assessment of the nature of the traumatic event, the duration since the event, the symptoms experienced, and the level of functional impairment.
