ICD-11 Criteria for Dissociative Disorders (6B60 )

ICD-11 Criteria for Dissociative Disorders (6B60 )

Dissociative disorders are characterised by involuntary disruption or discontinuity in the normal integration of one or more of the following: identity, sensations, perceptions, affects, thoughts, memories, control over bodily movements, or behaviour. Disruption or discontinuity may be complete, but is more commonly partial, and can vary from day to day or even from hour to hour. The symptoms of dissociative disorders are not due the direct effects of a medication or substance, including withdrawal effects, are not better explained by another Mental, behavioural, or neurodevelopmental disorder, a Sleep-wake disorder, a Disease of the nervous system or other health condition, and are not part of an accepted cultural, religious, or spiritual practice. Dissociative symptoms in dissociative disorders are sufficiently severe to result in significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

Coded Elsewhere:  Secondary dissociative syndrome (6E65)

6B60      Dissociative neurological symptom disorder

Dissociative neurological symptom disorder is characterised by the presentation of motor, sensory, or cognitive symptoms that imply an involuntary discontinuity in the normal integration of motor, sensory, or cognitive functions and are not consistent with a recognised disease of the nervous system, other mental or behavioural disorder, or other medical condition. The symptoms do not occur exclusively during another dissociative disorder and are not due to the effects of a substance or medication on the central nervous system, including withdrawal effects, or a Sleep-Wake disorder.

  • Factitious disorders (BlockL1‑6D5)

6B60.0    Dissociative neurological symptom disorder, with visual disturbance

Dissociative neurological symptom disorder, with visual disturbance is characterised by visual symptoms such as blindness, tunnel vision, diplopia, visual distortions or hallucinations that are not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and do not occur exclusively during another dissociative disorder.

6B60.1    Dissociative neurological symptom disorder, with auditory disturbance

6B60.2    Dissociative neurological symptom disorder, with vertigo or dizziness

Dissociative neurological symptom disorder, with vertigo or dizziness is characterised by a sensation of spinning while stationary (vertigo) or dizziness that is not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and does not occur exclusively during another dissociative disorder.

6B60.3    Dissociative neurological symptom disorder, with other sensory disturbance

Dissociative neurological symptom disorder, with other sensory disturbance is characterised by sensory symptoms not identified in other specific categories in this grouping such as numbness, tightness, tingling, burning, pain, or other symptoms related to touch, smell, taste, balance, proprioception, kinesthesia, or thermoception. The symptoms are not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and do not occur exclusively during another dissociative disorder.

6B60.4    Dissociative neurological symptom disorder, with non-epileptic seizures

Dissociative neurological symptom disorder, with non-epileptic seizures is characterised by a symptomatic presentation of seizures or convulsions that are not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and do not occur exclusively during another dissociative disorder.

6B60.5     Dissociative neurological symptom disorder, with speech disturbance

Dissociative neurological symptom disorder, with speech disturbance is characterised by symptoms such as difficulty with speaking (dysphonia), loss of the ability to speak (aphonia) or difficult or unclear articulation of speech (dysarthria) that are not consistent with a recognised disease of the nervous system, a neurodevelopmental or neurocognitive disorder, other mental, behavioural or neurodevelopmental disorder, or other medical condition and do not occur exclusively during another dissociative disorder.

6B60.6     Dissociative neurological symptom disorder, with paresis or weakness

Dissociative neurological symptom disorder, with paresis or weakness is characterised by a difficulty or inability to intentionally move parts of the body or to coordinate movements that is not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and does not occur exclusively during another dissociative disorder.

6B60.7     Dissociative neurological symptom disorder, with gait disturbance

Dissociative neurological symptom disorder, with gait disturbance is characterised by symptoms involving the individual’s ability or manner of walking, including ataxia and the inability to stand unaided, that are not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and do not occur exclusively during another dissociative disorder.

6B60.8     Dissociative neurological symptom disorder, with movement disturbance

Dissociative neurological symptom disorder, with movement disturbance is characterised by symptoms such as chorea, myoclonus, tremor, dystonia, facial spasm, parkinsonism, or dyskinesia that are not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and do not occur exclusively during another dissociative disorder.

6B60.80     Dissociative neurological symptom disorder, with chorea

Dissociative neurological symptom disorder, with chorea is characterised by irregular, non-repetitive, brief, jerky, flowing movements that move randomly from one part of the body to another that are not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and do not occur exclusively during another dissociative disorder.

6B60.81    Dissociative neurological symptom disorder, with myoclonus

Dissociative neurological symptom disorder, with myoclonus is characterised by sudden rapid jerks that may be focal, multifocal or generalised that are not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and do not occur exclusively during another dissociative disorder.

6B60.82     Dissociative neurological symptom disorder, with tremor

Dissociative neurological symptom disorder, with tremor is characterised by involuntary oscillation of a body part that is not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and does not occur exclusively during another dissociative disorder.

6B60.83     Dissociative neurological symptom disorder, with dystonia

Dissociative neurological symptom disorder, with dystonia is characterised by sustained muscle contractions that frequently causing twisting and repetitive movements or abnormal postures that are not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and do not occur exclusively during another dissociative disorder.

6B60.84     Dissociative neurological symptom disorder, with facial spasm

Dissociative neurological symptom disorder, with facial spasm is characterised by involuntary muscle contractions or twitching of the face that is not consistent with a recognised disease of the nervous system, other mental, behavioural or neurodevelopmental disorder, or other medical condition and does not occur exclusively during another dissociative disorder.

6B60.85     Dissociative neurological symptom disorder, with Parkinsonism

Dissociative neurological symptom disorder, with Parkinsonism is characterised by a symptomatic presentation of a Parkinson-like syndrome in the absence of confirmed Parkinson disease that does not occur exclusively during another mental, behavioural or neurodevelopmental disorder, other medical condition, or another dissociative disorder. Dissociative neurological symptom disorder, with Parkinsonism can be distinguished from Parkinson disease by features such as abrupt onset, early disability, bilateral shaking and slowness, nondecremental slowness when performing repetitive movements, voluntary resistance against passive movement without cogwheel rigidity, distractability, ‘give-way’ weakness, stuttering speech, bizarre gait, and a variety of behavioural symptoms.
