[A case of incest with dissociative amnesia and post traumatic stress disorder].

Incest is a kind of sexual abuse that causes serious disorders during childhood and adulthood. In order to overcome the trauma, abuse victims frequently use dissociative defence mechanisms. Post traumatic stress disorder, dissociative disorders, major depression and borderline personality disorder can be seen in the victims of childhood sexual abuse. In this article we present an adolescent who was found and brought to our clinic by the Children's Police Department while she was wandering around aimlessly. She could not remember anything about her identity or personal history. She had no apparent physical disturbances, marks of beating or wounds which could be seen externally. Her physical and neurological examinations were both normal. In her laboratory tests, there was nothing abnormal. No sign of intoxication or infection was detected. EEG and CT were also normal. After the family was found, we learned about the sexual and physical abuse and the patient was diagnosed with dissociative amnesia. The psychometric evaluations also supported our diagnosis. When the dissociation began to disappear, post traumatic stress disorder symptoms became more apparent. After she described her traumatic memories, PTSD symptoms began to recede. Through this case presentation we would like to emphasize the relationship between childhood physical and sexual abuse and dissociative disorders.
