**Core Concept:** Posttraumatic stress disorder (PTSD) is a psychiatric condition that occurs in individuals who have experienced or witnessed an extremely distressing event. PTSD is characterized by intrusive memories, avoidance behaviors, negative alterations in cognition and mood, and hyperarousal symptoms.
