Available data suggest the prevalence of DPDD is between 1.7 to 2.4% of the general population (Hunter et al., 2004), and prevalence studies have indicated that between 40 to 80% of psychiatric inpatients suffer from comorbid secondary depersonalization (Brauer et al., 1970 Hunter at al., 2005 Hunter et al., 2004).ĭPDD is differentiated from psychotic disorders due to its theoretical conceptualization being grounded in trauma and because reality testing remains unimpaired, meaning sufferers fully understand the difference between their internal world and the external world. Depersonalization is defined in the DSM-5 as “longstanding or recurring feelings of being detached from one's mental processes or body, as if one is observing themselves from the outside or in a dream,” and derealization as “the longstanding or recurring feeling of the external world of the individual being unreal”.

Although a consistent definition has been accepted by the psychology community since the late 1800’s, the disorder is still misunderstood and understudied, potentially because of the difficulty of non-sufferers to conceptualize the pathology and difficulty for individuals with these traits to verbalize their experiences.
