What is dissociative amnesia and its causes

Dissociative amnesia is a type of dissociative disorder that involves inability to recall important personal information that would not typically be lost with ordinary forgetting. It is usually caused by trauma or stress. Diagnosis is based on history after ruling out other causes of amnesia.

Dissociative amnesia has been linked to overwhelming stress, which may be caused by traumatic events such as war, abuse, accidents, or disasters. The person may have suffered the trauma or just witnessed it.
