Otherwise Specified Dissociative Disorder (OSDD) is a diagnosis within the DSM-V covering severe dissociative symptoms that do not fit any other diagnosis. There are five listed types of OSDD.

Subtypes[edit | edit source]

OSDD-1a[edit | edit source]

OSDD-1a is missing the distinct alters found in DID, preventing a diagnosis. Headmates are more blurry between one another and often have a core or shell identity. The identities with an OSDD-1a system may very similar or diverse; one common presentation is one individual within different "modes" or ages, like an angry self, a 12-year-old self, etc. OSDD-1a is different than typical mood changes due to the amnesiac barriers between headmates.

OSDD-1b[edit | edit source]

OSDD-1b is missing the amnesia found in DID, preventing a diagnosis. There is no amnesia related to switching. There may still be memory loss relating to trauma, but not between headmates.

OSDD-2[edit | edit source]

OSDD-2 is characterized by identity alteration due to brainwashing, programming, torture, thought reform, or otherwise coercion-based dissociation. Examples include being indoctrinated into a cult, programming, being held captive, etc.

OSDD-3[edit | edit source]

OSDD-3 is a transient diagnosis in which severe dissociative symptoms are present directly after a traumatic event. Depersonalization and derealization, amnesia, sudden loss of skills or coordination, etc and other signs usually last around a month. This diagnosis may last longer if this symptom (severe dissociation) occurs after every time a traumatic event happens to a patient.

OSDD-4[edit | edit source]

OSDD-4 is described as dissociative trances that do not have any other cause (including other conditions, spiritual practices, or drug use). Individuals slip in and out of these trance states, often unaware of their environment while in them, and may "come to" confused and missing memories of their time while dissociating.

Related Terms[edit | edit source]

OSDD is one of multiple dissociative disorders listed within the DSM-V, including DID, UDD, and depersonalization/derealization.

Systems that experience both a lack of distinct headmates and a lack of amnesia while still being plural may identify as a median system.

Only OSDD-1 is considered an inherently-plural disorder, but the others often intersect with other forms of plurality.

History[edit | edit source]

In earlier iterations of the DSM, the term DDNOS (Dissociative Disorder Not Otherwise Specified) many other experiences that were later sorted into existing diagnoses. This graphic explains the shift.
