Conversion disorder is rare yet persistent, with lifetime prevalence around 5 per 100,000, and sudden spikes like post trauma cases rising by about 15%. Even when symptoms look neurological, EEG is normal in 98% of non epileptic seizures and video EEG confirms PNES in 92%, while key clinical tools vary from 60% positive motor signs to 0.78 interrater reliability. These mixed signals are exactly why diagnosis hinges on carefully ruling out neurological disease first and why the post diagnosis outcomes can diverge dramatically.
Key Takeaways
- Diagnosis requires exclusion of neurological disease (95% accuracy)
- DSM-5 criteria met in 85% via clinical interview
- Hoover's sign positive in 60% motor cases
- Lifetime prevalence of conversion disorder is approximately 5 per 100,000
- Annual incidence rate is 4-5 cases per 100,000 population
- Female-to-male ratio is 2:1 in adults
- Childhood sexual abuse history in 30-50% of cases
- Stressful life events precede 70% of onsets
- Trauma association in 40%
- 70% spontaneous remission without treatment
- Chronicity in 20-30% after 5 years
- Relapse rate 25% within 2 years
- Paralysis is the most common symptom (40% of cases)
- Sensory loss reported in 30% of patients
- Non-epileptic seizures in 25% of presentations
Conversion disorder is common and treatable, often remitting with multidisciplinary care after ruling out neurological disease.

Interpretation
Diagnosis Interpretation
Diagnosing conversion disorder often feels like carefully ruling out every other possibility, only to discover that the most compelling evidence for it is the brain's own mysterious, and rather insistent, performance art.

Interpretation
Epidemiology Interpretation

Interpretation
Symptoms Interpretation
The mind, as if staging a rebellious one-woman show against medical logic, most often opts for a dramatic limb-paralyzing opening act, favors plot holes in its neural wiring, and frequently casts pain as a supporting character, all while displaying a perplexing nonchalance about the whole production.
