Abstract: The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) diagnostic criteria for conversion disorder have replaced the criterion of evidence of a "psychogenic" etiology with a criterion that patients must be "positively" diagnosed on the basis of their neurological assessment. We retrospectively studied referrals to a specialist functional neurology clinic to see how commonly the new criteria were met since DSM-5's introduction. Positive signs were reported in a quarter of referrals (26.5%), which was associated with diagnosticians' confidence (p = 0.001) and with the clinic confirming the diagnosis (p = 0.01). Our clinic found positive signs in 28.6% of the referrals. In 13 (13.3%) patients, the new criterion was not met. In conclusion, positive signs are diagnostically helpful but are only reported in a minority of assessments. A significant group of those currently believed to have conversion disorder would not meet the revised diagnostic criteria based on this.
