1. Chronic and recurrent syndromes of mixed dissociative symptoms. This category includes identity disturbance associated with less than marked discontinuities in sense of self and agency, or alterations of identity or episodes of possession in an individual who reports no dissociative amnesia.
2. Identity disturbance due to prolonged and intense coercive persuasion: Individuals who have been subjected to intense coercive persuasion (e.g., brainwashing, thought reform, indoctrination while captive, torture, long-term political imprisonment, recruitment by sects/cults or by terror organizations) may present with prolonged changes in, or conscious questions of, their identity.
3. Acute dissociative reactions to stressful events: This category is for acute, transient conditions that typically last less than 1 month, and sometimes only a few hours or days. These conditions are characterized by constriction of consciousness; depersonalization; derealization; perceptual disturbances (e.g., time slowing, macropsia); micro-amnesias; transient stupor; and/or alterations in sensory-motor functioning (e.g., analgesia, paralysis).
4. Dissociative trance: This condition is characterized by an acute narrowing or complete loss of awareness of immediate surroundings that manifest as profound unresponsiveness or insensitivity to environmental stimuli. May be accompanied by minor stereotyped behaviors of which the individual is unaware and/or that he or she cannot control, as well as transient paralysis or loss of consciousness.
