Conversion disorder (functional neurologic symptom disorder) is characterized by neurologic symptoms (eg, weakness, abnormal movements, or nonepileptic seizures) that are inconsistent with a neurologic disease, but cause distress and/or impairment [1]. The disorder is common in clinical settings and often has a poor prognosis [2-5].

This topic reviews the epidemiology, pathogenesis, and prognosis of conversion disorder. The terminology, diagnosis, differential diagnosis, clinical features, assessment, and treatment are discussed separately, as are specific subtypes of conversion disorder (psychogenic nonepileptic seizures and psychogenic movement disorders):

(See "Conversion disorder in adults: Terminology, diagnosis, and differential diagnosis".)
