Depersonalization Derealization Disorder
Diagnosis of Depersonalization Derealization Disorder
Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) criteria Medical and psychiatric examination to rule out other causes Diagnosis of depersonalization/derealization disorder is clinical, based on the presence of the following criteria in the DSM-5-TR: Patients have persistent or recurrent episodes of depersonalization, derealization, or both. Patients know that their dissociative experiences are not real (ie, they have an intact sense of reality). Symptoms cause significant distress or significantly impair social or occupational functioning. Also, the symptoms cannot be better accounted for by another medical or psychiatric disorder (eg, seizures, ongoing substance use disorder, panic disorder, major depressive disorder, another dissociative disorder). MRI and electroencephalography (EEG) are performed to rule out structural causes, particularly if symptoms or progression is atypical (eg, if symptoms begin after age 40 years). Urine toxicology tests may also be indicated. Psychologic tests and special structured interviews and questionnaires, such as the Multidimensional Inventory of Dissociation ( Diagnosis reference ), are helpful. 1.Simeon D, Knutelska M: The Multidimensional Inventory of Dissociation (MID) in Depersonalization Disorder: General Findings with a clinical emphasis on memory and identity disturbances.J Trauma Dissociation24:185-196, 2023. doi: 10.1080/15299732.2022.2119634
