1. Specify whether dissociative symptoms are present as manifested by either of the following :

1. 1. 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).
   2. 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:
