Comparative Characteristics of Dissociative Disorders ( DSM-IV )
Symptoms
| Dissociative amnesia | Dissociative fugue | Dissociative Identity Disorder | Depersonalization disorder |
|---|---|---|---|
| Loss of memory, usually sudden. The patient is aware of memory loss. Before and after memory loss, consciousness is not impaired. | Travel, often over long distances. Amnesia of its past. The patient is often not aware of memory loss. Often assigns new personal qualities. During the fugue period, the behavior does not differ from the behavior of a mentally healthy person. | The coexistence of two or more personalities in one person, each of which periodically determines his behavior and way of thinking. A sudden transition from one person to another. Usually does not remember the existence of other personalities in which he reincarnated. | A steady experience of the unreality of your body and self. Assessment of external reality does not suffer. |
Epidemiology
| Dissociative amnesia | Dissociative fugue | Dissociative Identity Disorder | Depersonalization disorder |
|---|---|---|---|
| The most common dissociative disorder. More often occurs in people who survived natural disasters, the war. It is more common in women. It occurs more often in adolescence and young age. | It is rare. Most often occurs in people who survived natural disasters, the war. Prevalence by gender and age varies. | It is not as rare as previously thought. It is determined in 5% of all patients with mental disorders. It occurs in adolescence and young age (possibly at a much earlier age). In women, it is more common. Increased risk of illness in close relatives. | As an independent disorder, it is rare; periodic episodes of depersonalization are noted. Rarely observed in people over 40 years old. Perhaps more common among women. |
Etiology
| Dissociative amnesia | Dissociative fugue | Dissociative Identity Disorder | Depersonalization disorder |
|---|---|---|---|
| Emotional trauma (for example, violence by family members). Somatic or neurological etiology is excluded. | Emotional trauma. Intense alcohol consumption may predispose to the disorder. Predisposing factors are various personality disorders (for example, schizoid). Somatic or neurological etiology is excluded. | Cruel psychological or physical (often sexual) violence in childhood. Lack of support from significant individuals. May coexist with epilepsy. Somatic or neurological etiology is excluded. | Predisposing factors - severe stress, trauma, depression. Somatic causes are excluded. |
Current and Forecast
| Dissociative amnesia | Dissociative fugue | Dissociative Identity Disorder | Depersonalization disorder |
|---|---|---|---|
| Sudden end to the disorder. A few relapses . | Usually short-term - from several hours to several days. Sometimes it lasts for months and is accompanied by movement, often over long distances. Recovery usually occurs spontaneously and quickly. Rare relapses. | The most severe of dissociative disorders with the greatest likelihood of a chronic course. Incomplete recovery. | The onset is usually sudden. Has a tendency to chronic course. |
