INTRODUCTION

Depersonalization/derealization disorder (DDD) is characterized by persistent or recurrent depersonalization and/or derealization that causes clinically significant distress. Reality testing remains intact [1].

DDD has a lifetime prevalence in the general population of approximately 2 percent and is associated with significant morbidity, but often goes undetected or misdiagnosed, leading to delays in treatment.

This topic discusses psychotherapy for DDD. The epidemiology, pathogenesis, clinical manifestations, course, and diagnosis of DDD are discussed separately. Pharmacotherapy for DDD is also discussed separately. (See "Depersonalization/derealization disorder: Epidemiology, pathogenesis, clinical manifestations, course, and diagnosis" and "Pharmacotherapy of depersonalization/derealization disorder".)

DEFINITIONS

Depersonalization — Depersonalization is a persistent or recurrent feeling of detachment or estrangement from one’s self. An individual experiencing depersonalization may report feeling like an automaton, as if in a dream, or as if watching himself or herself in a movie. Depersonalized individuals may report the sense of being an outside observer of their mental processes or their body. They often report feeling a loss of control over their thoughts, perceptions, and actions. (See "Depersonalization/derealization disorder: Epidemiology, pathogenesis, clinical manifestations, course, and diagnosis", section on 'Clinical manifestations'.)

Derealization — Derealization is a subjective sense of detachment or unreality regarding the world around them (eg, other individuals or objects are experienced as unreal, dreamlike, foggy, lifeless, or visually distorted). (See "Depersonalization/derealization disorder: Epidemiology, pathogenesis, clinical manifestations, course, and diagnosis", section on 'Clinical manifestations'.)
