Conversion Disorders: Follow-up
Updated: Dec 22, 2008
Follow-up
Prognosis
- Spontaneous resolution in most - Approximately 75%
- Recurrence of same or different conversion symptoms - Approximately 25% in 15-year follow-up studies
- False-positive diagnosis of conversion disorder
- Approximately 25% are diagnosed with neurological disease in 10-year follow-up that could account for presenting symptoms.
- Multiple sclerosis, neurodegenerative diseases, structural myelopathy, peripheral neuropathy, dystonia, and myopathy accounted for the false-positive diagnoses.
- Good prognostic factors - Acute onset of symptoms, short duration of symptoms, healthy premorbid functioning, higher intelligence, absence of coexisting psychopathology, presence of an identifiable stressor, male gender, change in marital status (marriage or divorce), isolated sensory symptoms, very young age, and good premorbid medical health status.1
- Poor prognostic symptoms - Pseudoseizure (psychogenic nonepileptic seizure), psychogenic tremor, subclinical (undiagnosed) personality pathology, concomitant medical illness, the presence of a stuffed animal brought to the hospital by the patient,35 poor perception of own well-being, motor symptoms, and pending litigation.1
- Recent retrospective study of psychogenic nonepileptic seizure over a 5-year period showed 47% of patients were unemployed, 26% were not living independently, and only 16% were seizure free at 21 months post diagnosis of psychogenic nonepileptic seizure.36
- Of children with a diagnosis of conversion disorder, 85% are symptom free at 5 years with a reported improvement in status in another 5%.37
Patient Education
- Sensitively review the disorder with the patient and the family in such a way as to not place blame. During such follow-up for review of completed imaging and other studies, continue to emphasize the importance of pain or other symptoms that the patient may be having.
- Continue to reassure the patient that the negative test results are good news and bode well for their eventual recovery.
- Frequent brief office visits to ensure the expected resolution of their symptoms may be helpful.
- Web sites that may provide further information and support for patient and family education include the following:
- Johns Hopkins Medicine, Conversion Disorder
- MayoClinic.com, Conversion disorder
- Mental Health Forum
- Psych Forums
Miscellaneous
Medicolegal Pitfalls
- Delay in diagnosing organic disease due to lack of appropriate evaluation
- Unnecessary interventional or invasive diagnostic tests resulting in iatrogenic illness
- Overly direct or confrontational presentation of the diagnosis, which may entrench the symptom and lead to prolonged patient disability
