- reported incidence of conversion symptoms varies widely depending on the
population studied
- studies have estimated that 20 to 25 percent of patients in a general
hospital setting have individual symptoms of conversion, and five percent
of patients in this setting meet the criteria for the full disorder
- medically unexplained neurological symptoms account for approximately
30 percent of referred neurology outpatients
- in a study of 100 randomly selected patients from a psychiatry clinic,

- studies have estimated that 20 to 25 percent of patients in a general
hospital setting have individual symptoms of conversion, and five percent
of patients in this setting meet the criteria for the full disorder
- with respect to incidence of conversion disorder
- among adults, women diagnosed with conversion disorder outnumber men by a 2:1 to 10:1 ratio
- less educated people and those of lower socioeconomic status are more likely to develop conversion disorder
