Cluster of dissociative disorders

Other specified dissociative disorder
(OSDD) is a mental wellness diagnosis for pathological dissociation that matches the DSM-v criteria for a dissociative disorder, but does non fit the full criteria for any of the specifically identified subtypes, which include dissociative identity disorder, dissociative amnesia, and depersonalization/derealization disorder, and the reasons why the previous diagnoses were not met are specified. “Unspecified dissociative disorder” is given when the clinician does non give a reason.[one]
The International Statistical Classification of Diseases and Related Health Bug (ICD-ten) refers to the diagnosis as “Other dissociative and conversion disorders”.[2]
Under the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM), information technology was known every bit
“Dissociative disorder not otherwise specified” (DDNOS).

Examples of OSDD include chronic and recurrent syndromes of mixed dissociative symptoms, identity disturbance due to prolonged and intense coercive persuasion, disorders like to dissociative identity disorder, astute dissociative reactions to stressful events, and dissociative trance.[1]

In that location are currently 4 examples of OSDD given in the DSM. OSDD is a “catch-all” category for whatsoever presentation that is abnormal but doesn’t meet the diagnostic criteria for any of the dissociative disorders, and therefore the examples given are not the only presentations of OSDD possible. OSDD is simply diagnosed when it is known that another dissociative disorder isn’t present; if the diagnosis is yet being clarified, or if there is not plenty fourth dimension to brand an informed diagnosis (such as in an emergency room setting), a diagnosis of Unspecified Dissociative Disorder may exist given.

It is worth noting that a person volition not be diagnosed with “OSDD blazon 4” (for example); instead they volition simply be diagnosed with OSDD. The diagnosing clinician may specify in the client’due south file that the diagnosis is “OSDD (dissociative trance)”, but in general the uncomplicated diagnosis of OSDD will be given.

OSDD blazon one


OSDD-1 is diagnosed when a person is experiencing sub-threshold dissociative identity disorder (DID).

The DSM states that “This category includes identity disturbance associated with less-than-marked discontinuities in sense of self and agency, or alterations of identity or episodes of possession in an individual who reports no dissociative amnesia.[1]“.

The ICD-11 describes OSDD-1 equally “Partial dissociative identity disorder

OSDD type two


OSDD-2 describes a dissociative identity disturbance caused past “prolonged and intense coercive persuasion”.[1]
The DSM gives the examples of “brainwashing, thought reform, indoctrination while captive, torture, long-term political imprisonment, recruitment by sects/cults or by terror organizations.” People with OSDD-2, as a issue, feel pitiful changes to and/or questioning of their identity.[one]

OSDD type iii


OSDD-iii is diagnosed when a person experiences acute dissociative reactions to stressful events. These reactions final anywhere from a few hours to weeks, but typically less than a month. The dissociative conditions are characterised by “constriction of consciousness”, including “depersonalization; derealization; perceptual disturbances (east.g., time slowing, macropsia); micro-amnesias; transient shock; and/or alterations in sensory-motor performance (e.g., analgesia, paralysis).[i]

OSDD type 4


OSDD-4 is characterised past a dissociative trance; “an acute narrowing or consummate loss of awareness of immediate surroundings that manifests as profound unresponsiveness or insensitivity to ecology stimuli.”[1]
The DSM specifies that “The dissociative trance is not a normal function of a broadly accepted commonage cultural or religious practise”.

In the ICD-11, this status warrants a carve up diagnosis of
Trance disorder.[viii]
