Post Traumatic Stress Disorder (PTSD) is a disorder that can develop after an individual experiences an event that produces a sense of overwhelming helplessness and/or powerlessness such as childhood abuse and neglect, rape, war combat, car accidents, or hurricanes. PTSD is said to be "a normal response to abnormal events." Symptoms of PTSD include re-experiencing or reliving the trauma through flashbacks or nightmares, avoidance of situations or people that are reminders of the traumatic event, negative change in beliefs and feelings, and hyperarousal (feeling 'on edge'). PTSD is treated through different modalities of psychotherapy such as Eye movement desensitization and reprocessing (EMDR) and Cognitive Processing Therapy (CPT) as well as pharmacotherapy.
