Posttraumatic Stress Disorder (PTSD; F43.10) Specifiers
1. Specify whether dissociative symptoms are present as manifested by either of the following :
- With Depersonalization: Persistent or recurrent experiences of feeling detached from one’s mental processes or body (e.g., feeling as though one were in a dream).
- With Derealization: Persistent or recurrent experiences of unreality of surroundings (e.g., the world around the individual is experienced as unreal, dreamlike, distant, or distorted).
*Note: The dissociative symptoms must not be attributable to the physiological effects of a substance (e.g., blackouts, behavior during alcohol intoxication) or another medical condition (e.g., complex partial seizures).
2. Specify if:
- With Delayed Expression: If the full diagnostic criteria are not met until at least 6 months after the event (although the onset and expression of some symptoms may be immediate).
