Area of Science:

  • Psychiatry
  • Neurology
  • Psychology

Background:

  • Conversion disorder subtypes are poorly defined in existing literature.
  • Research often focuses narrowly on pseudoseizures, neglecting other presentations.
  • DSM-IV outlines four subtypes, but empirical differentiation is limited.

Purpose of the Study:

  • To investigate empirical differences between the four DSM-IV conversion disorder subtypes.
  • To explore the potential for reclassifying conversion disorder subtypes based on distinct characteristics.
  • To analyze demographic and psychometric variations across conversion disorder subtypes.

Main Methods:

  • Ninety-five patients diagnosed with conversion disorder were evaluated.
  • Subtypes were classified according to DSM-IV criteria.

  • Patients completed the Patients Information Form and the Dissociative Experience Scale (DES).

    • Main Results:

    • Prevalence: Motor (25.2%), Sensory (5.2%), Seizures (24.2%), Mixed (47.3%).
    • Significant differences observed in occupation, psychiatric family history, hospitalization rates, and settlement location.
    • Dissociative Experience Scale (DES) scores varied significantly across the subtypes.

    Conclusions:

    • The four conversion disorder subtypes exhibit distinct clinical and demographic profiles.
    • Findings support the need for re-evaluating and potentially reclassifying conversion disorder subtypes.
    • Dissociative experiences are a key differentiating factor among conversion disorder presentations.
