Dissociative neurological symptom disorder
A disorder characterized by motor or sensory neurological symptoms that cannot be explained by an established neurological or medical condition. Symptoms may include weakness, tremor, seizures, sensory loss, or movement disorders. There is often an association with psychological stressors.
Symptoms
- Motor symptoms inconsistent with neurological damage (also: Motor symptoms inconsistent with neurological damage, motor symptoms not neurologically explained, psychogenic motor symptoms, motor conversion symptoms, motor symptoms without neurological cause)
- Sensory symptoms without organic explanation (also: Sensory symptoms without organic explanation, sensory symptoms not neurologically explained, sensory conversion symptoms, psychogenic sensory symptoms, sensory symptoms without cause)
- Sudden loss of neurological function without organic cause (also: Sudden loss of neurological function without identifiable cause, sudden loss of neurological function, sudden neurological disorder, loss of nerve function, sudden absence of neurological function)
- Symptoms appearing or worsening after stress (also: Symptoms appearing or worsening after stress or difficult experience, symptoms worsening in stressful situations, worsening of symptoms under stress, symptoms increase with stress, stress worsens symptoms)
- Symptoms variable and inconsistent with neurological pattern (also: Symptoms variable and inconsistent with neurological pattern, inconsistency of neurological symptoms, heterogeneous neurological symptoms, variability of symptoms, inconsistent neurological picture)
- Non-organic neurological symptoms (also: Paresis, ataxia, apraxia, akinesia without correlation on MRI/EMG, functional paresis, psychogenic paralysis, dissociative ataxia, functional apraxia)
- Seizures without tongue biting, cyanosis, or injury on falling (also: PNES – psychogenic non-epileptic seizures, pseudo-seizures, seizures without loss of sphincter control, no tongue biting, seizures without involuntary urination)
- Sensory anesthesia inconsistent with peripheral nerve anatomy (also: stocking-glove distribution of sensory loss, sensory boundary at body midline, blindness with preserved responses to stimuli, psychogenic deafness, anesthesia inconsistent with dermatomes)
