ObjectiveTo evaluate the efficacy of an early multidisciplinary (neurology and psychiatry) intervention for conversion disorder (CD).MethodsConsecutive patients newly diagnosed with CD from 2005 to 2007 were compared to a control group of newly diagnosed CD patients receiving usual care. At 3 years, a questionnaire evaluated self‐rated subjective outcome, symptom severity, SF‐36 scores, employment status and medical care use.ResultsData from 12 cases (mean age 25.5 ± 8.2; 9 females) and 11 controls (mean age 34.7 ± 13.5; 10 females) showed that 83% of cases had a good subjective outcome (symptom improved or cured) when only 36% of controls had a good outcome (p < 0.05). Cases significantly improved their SF‐36 scores on subscales involving physical complaints compared to controls. A minority (20%) of cases reduced or ceased professional activity when 70% of controls did (p < 0.001). Only 16% of cases sought further medical advice for the initial symptom when 73% of controls did. Both groups accepted psychiatric referrals (83% of cases and 73% of controls) and found it beneficial.ConclusionsEarly intervention involving both neurologists and psychiatrists is effective for CD in alleviating physical complaints, reducing sick leave and health care use.
