Posttraumatic stress disorder (PTSD), that might emerge as a result of exposure to a recognizable man made or natural disaster has recently been the focus of attention of professionals working in the area of psychiatry. Most of the information available on the onset, course, treatment and prognosis of the disorder comes from the results of studies executed with the traumatized adult population. Studies made with the child and adolescent victims of trauma are far less common. This paper aims to review the available limited information on the course of PTSD in children and adolescents.
