ICD-11 Criteria for Possession Trance Disorder (6B63)
Possession trance disorder is
characterised by trance states in which there is a marked alteration in the
individual’s state of consciousness and the individual’s customary sense of
personal identity is replaced by an external ‘possessing’ identity and in which
the individual’s behaviours or movements are experienced as being controlled by
the possessing agent. Possession trance episodes are recurrent or, if the
diagnosis is based on a single episode, the episode has lasted for at least
several days. The possession trance state is involuntary and unwanted and is
not accepted as a part of a collective cultural or religious practice. The
symptoms do not occur exclusively during another dissociative disorder and are
not better explained by another mental, behavioural or neurodevelopmental
disorder. The symptoms are not due to the direct effects of a substance or
medication on the central nervous system, including withdrawal effects,
exhaustion, or to hypnagogic or hypnopompic states, and are not due to a disease
of the nervous system or a sleep-wake disorder. The symptoms result in
significant distress or significant impairment in personal, family, social,
educational, occupational or other important areas of functioning.
Exclusions:
- Schizophrenia (6A20)
- Disorders due to use of other specified psychoactive substances, including medications (6C4E)
- Acute and transient psychotic disorder (6A23)
- Secondary personality change (6E68)
