Dissociative disorder not otherwise specified (DDNOS) is a mental health diagnosis for pathological dissociation that matches the DSM-IV criteria for a dissociative disorder, but does not fit the full criteria for any of the specifically identified subtypes, which include depersonalization disorder, dissociative amnesia, dissociative fugue, and dissociative identity disorder.[1] The International Statistical Classification of Diseases and Related Health Problems (ICD-10) refers to the diagnosis as dissociative disorder unspecified.[2]

Examples of DDNOS include Ganser's syndrome, disorders similar to dissociative identity disorder, chronic dissociative states as a result of being exposed to coercive persuasion, and derealization unaccompanied by depersonalization.[3] DDNOS is the most common dissociative disorder and is diagnosed in 40% of dissociative disorder cases.[4] It is often co-morbid with other mental illnesses such as complex posttraumatic stress disorder, major depressive disorder, personality disorders, substance abuse disorders and eating disorders.[5]
