Conversion disorder, also known as functional neurological symptom disorder (FND), is a psychiatric disorder characterized by symptoms affecting sensory or motor function. These signs and symptoms are inconsistent with patterns of known neurologic diseases or other medical conditions. Although conversion disorder has no organic basis, the symptoms significantly impact a patient’s ability to function. Moreover, the symptoms cannot be controlled at will and not considered to be feigned intentionally by the patient. The term “conversion disorder” was first mentioned in literature by Sigmund Freud (1856-1939). The Austrian neurologist and founder of psychoanalysis believed that functional symptoms that could not be explained by neurologic diseases or other underlying medical conditions reflected an unconscious conflict.[1] In this context, the word "conversion" refers to replacing a somatic symptom with a repressed idea. The understanding of conversion disorder is still largely limited and continually evolving.[2]
