Dissociative fugue, or psychogenic fugue, formerly known as fugue state, is a rare schizophrenic disorder that causes amnesia of personal identity, including memories, personality, and other distinguishing features of the individual, but it is treatable. The condition may last days, months, or perhaps longer, and is usually accompanied by symptoms such as unplanned travel or wandering, and sometimes the creation of a new identity. According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), this disorder is one aspect of dissociative amnesia. Memories can usually be restored as they were after recovery from the fugue state, and no further treatment is required. In addition, a fugue episode is not classified as a mental disorder if it is due to taking psychotropic drugs, exposure to physical trauma, dissociative identity disorder, flatulence, dementia, or if it is a general medical condition. A series of long-term traumatic episodes causes fugue states, which are common in victims of childhood sexual abuse who learn over time to separate the memory of the abuse. Symptoms of dissociative fugue include mild confusion, and once the person recovers from the fugue state, they may develop depression, feelings of sadness, shame, and discomfort. People with the disorder have also experienced post-fugue anger. Loss of identity may also be a symptom of the fugue state. A doctor may suspect dissociative fugue when a person appears confused about their identity, feels confused about their past, or denies in interviews their new identity or denies the existence of one or both identities. The doctor also reviews symptoms and performs a physical examination to rule out any physical disorders that could contribute to or cause amnesia. Sometimes, dissociative fugue can only be diagnosed when the person regains their previous identity before the fugue and is distressed by finding themselves in unfamiliar circumstances, and sometimes by realizing “lost time.” The diagnosis is usually made retrospectively, i.e., the doctor reviews the history and collects information that documents the patient’s condition before they traveled and left their home country and before establishing their alternative life. Functional amnesia can also be specific to a particular case, which differs from all forms and types of trauma or experiences of violence in general, in which the person suffers from severe amnesia as a result of being exposed to a specific trauma. All of the following cause specific amnesia: committing murders or committing or being exposed to a violent crime such as rape and torture, or experiencing anti-violence work or attempting suicide. Or being in car accidents or disasters, and he noted that caution should be exercised when diagnosing cases of psychogenic amnesia when there are convincing motives to pretend to have a memory deficit for legal or financial reasons, and although a small proportion of cases of psychogenic amnesia can be explained in this way, it is generally accepted that true cases are not rare, and both general amnesia and amnesia specific to a particular condition are often distinguished from organic amnesia syndrome in that the ability to store memories and new experiences in them remains the same, and usually a concerted effort is made to help the person regain his identity and history, due to the very sensitive nature of amnesia in such cases, which are sometimes dramatic as well, and sometimes this will help to resolve the matter automatically when treated with certain treatments. The cause of the fugue state is related to dissociative amnesia, which has a number of other subtypes: selective amnesia, generalized amnesia, persistent amnesia, organized amnesia, as well as the subtype "dissociative fugue". Unlike retrograde amnesia, dissociative amnesia is not due to the direct physiological - i.e., functional - effects of a substance or to a neurological or other general health condition; it is a complex neuropsychological process. The emergence of a defensive personality in a person suffering from dissociative fugue is considered by some to be a rational fear of the situation; Because this person may have recently experienced a recurrence of an event or person that was a traumatic event in their life. Accordingly, the term “fugue state” may carry a slight semantic distinction from “dissociative fugue,” as the former indicates a greater degree of “movement.” For the purposes of this article, a “fugue state” occurs during an “enactment” of a “dissociative fugue.” The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) defines “dissociative fugue” as: The Merck Manual defines “dissociative fugue” as: One or more episodes of amnesia in which a person is unable to recall some or all of his or her past, either with the loss of his or her identity or with the formation of a new identity, which occurs with sudden, unexpected travel intended to be away from home. To support this definition, dissociative amnesia is also defined as: The inability to recall important personal information, usually of a traumatic or stressful nature, for a period so long that it cannot be explained by ordinary forgetfulness. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV-TR) states that the period of fugue may last from days to months, and recovery is usually rapid, but some cases are resistant to treatment, and the individual often experiences only one episode.
