Dissociative neurological symptom transtorno 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 com a recognised disease of the nervous system, other mental or behavioural transtorno, or other medical condition. The symptoms do not occur exclusively during another dissociative transtorno and are not due to the effects of a substance or medication on the central nervous system, including abstinência effects, or a Sleep-Wake transtorno.
