What will be an ideal response?
Posttraumatic stress disorder is an emotional disorder that follows a trauma in which one feels fear, helplessness, or horror. Victims later experience vivid memories and nightmares, display restriction or numbing of emotional responsiveness, may be unable to remember certain aspects of the event, and may remember the event.
Acute stress disorder is PTSD that occurs within the first month after the trauma. People with this disorder may display severe dissociative symptoms, amnesia for all or part of the trauma, emotional numbing, derealization, and feelings of unreality.
People with acute stress disorder experience very severe early reactions to trauma that did not meet the criteria for PTSD but over time may eventually develop PTSD.
