ICD-11

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.

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.
