Dissosiativ identitetsforstyrrelse i utredning av barn og ungdom: Teori og kliniske utfordringer

Background: Clinical practice and recent research indicate that dissociative symptoms and disorders are left unidentified and undiagnosed by health professionals. Based on a clinical case from our work setting, this article describes relevant literature regarding dissociation and dissociative disorders to add to the knowledge of the theoretical and phenomenological features of complex dissociative disorders. Further, we describe differential diagnostic challenges that may arise in clinical practice. Methods: Both systematic and non-systematic literature searches were performed. Findings: Recent research shows the Trauma model to be central to understanding dissociative disorders. Symptoms can be mistaken for cognitive difficulties, oppositional issues or other somatic symptoms. Quantitative measures, systematic observations and clinical evaluations are fundamental for identifying dissociative symptoms and disorders. Implications: There is potential for identifying and evaluating dissociative symptoms at an earlier stage. Interdisciplinary and differential diagnostic evaluations are crucial to provide adequate understanding, assessment, and treatment of these patients.
