What is Dissociative Disorder NOS?

A dissociative disorder NOS (Not Otherwise Specified) is a disorder which is characterized by dissociative symptoms, such as a disturbance in the typically integrated functions of consciousness, memory, identity, or perception and these disruptions may be abrupt or slow, transient or chronic. 1 Dissociation is the detachment of memories or thoughts from reality and usual consciousness.

Dissociative disorder NOS can be utilized if it does not meet the criteria for any specific dissociative disorders 2 which includes dissociative amnesia, dissociative fugue, depersonalization disorder and dissociative identity disorder, which is formerly known as multiple personality disorder. These disorders are different from each other. They are unique based on the kind and length of the stressors. Additionally, the type and severity of their symptoms also differ from one another. 3

This disorder has a combination of 4 other types of dissociative disorders which might have similar characteristics to other disorders. Dissociative disorder NOS is not a mental illness but rather a disorder, so a person with this disorder is usually sane, very intelligent, and has a high need to live and carry on. 4 Types of Dissociative Disorders include the following:

  • Dissociative Amnesia.

People usually forget things, places, or events, but in dissociative amnesia, the person has difficulty remembering important personal information that is traumatic and stressful in nature. Unlike the usual type of amnesia, dissociative amnesia is not a result from a head trauma or other psychological conditions.

  • Dissociative Fugue.

This disorder is a rare because it is characterized by a sudden departure from usual residence and forgetting about the past which is linked with confusion. A person has abruptly departed his/her identity when traveling or on a journey. He/she will assume and adopt a new identity in a new place or setting. This might last for a short period of time or can last for a few months but no longer than that.

  • Depersonalization Disorder.

This disorder describes an abrupt feeling of detaching your body, thoughts, and experience from your own but still in touch with reality. This may last for a few moments or might continue for years.

  • Dissociative Identity.

Also known as multiple personality disorder and the most well-known from all dissociative disorders; this disorder illustrates two or more separate identities in a person, each with different way of thinking or memory.
