dissociative trance disorder
a dissociative disorder characterized by involuntary alterations in consciousness, identity, awareness or memory, and motor functioning that result in significant distress or impairment. The two subtypes of the disorder are distinguished by the individual’s identity state. In possession trance, the individual’s usual identity is replaced by a new identity perceived to be an external force, such as a ghost, another person, or a divine being, and there is loss of memory for the episode of trance. In trance disorder, individuals retain their usual identity but have an altered perception of their milieu. These types of dissociative experiences are common in various cultures and may be part of customary religious practice; they should not be regarded as pathological unless considered abnormal within the context of that cultural or religious group. Also called possession trance disorder; trance and possession disorder
(TPD).
