Conversion hysteria is a term commonly used in psychology to describe a medical condition where a person experiences physical symptoms that cannot be fully explained by a medical diagnosis. However, this term has been criticized for its gendered history and questionable scientific basis. As such, several more neutral and inclusive terms have been suggested to describe this condition. Some of these synonyms include "functional neurological disorder," "psychogenic disorder," and "somatic symptom disorder." These terms aim to more accurately reflect the medical complexity of the condition while avoiding stigma and prejudice associated with conversion hysteria.
