Which disorder involves depersonalization and derealization?

The disorder that specifically involves experiences of depersonalization and derealization is Depersonalization/Derealization Disorder. This condition is characterized by a marked sense of detachment from one’s thoughts, feelings, or sense of self (depersonalization) and/or a sense of unreality or distance from one’s surroundings (derealization). Individuals may feel as though they are observing themselves from outside their body or feel as if the world around them is not real.

This diagnosis is distinct and focuses on these specific experiences, which can be disruptive and distressing for those affected. The symptoms can be acute or chronic and may occur in response to stress or traumatic events, but the presence of depersonalization and derealization is essential for the diagnosis, distinguishing it from other disorders. In other conditions like Dissociative Identity Disorder, Major Depressive Disorder, or Post-Traumatic Stress Disorder, while dissociative symptoms may be present, the primary features differ significantly, which is why they do not specifically focus on depersonalization and derealization as their core symptoms.
