Dissociative Amnesia is a condition where a person cannot recall important personal information. It can be caused by stress or trauma and can result in memory loss that can last for days or even years. Synonyms for the term include Psychogenic Amnesia, Functional Amnesia, and Traumatic Amnesia. Other related terms include Fugue State, which is a type of dissociative amnesia where a person temporarily loses their sense of identity and may wander away from their usual environment. Another related condition is Depersonalization Disorder, which involves feeling detached from one's body or the world around them. These conditions can be treated with psychotherapy and other forms of counseling.
