A functional disorder is a medical condition that impairs the normal function of a bodily process. Definitions vary between fields of medicine, with orthopedics using it to describe a structural defect, such as a misshapen bone, and psychiatry and neurology using it to mean an emotional disorder. Sometimes, the term functional disorder is used to describe physical manifestations of psychological problems.[1]
Generally, the mechanism that causes a functional disorder is unknown, poorly understood, or, occasionally, unimportant for treatment purposes.
Status
Whether a given medical condition is termed a functional disorder depends in part on the state of knowledge. Some diseases, including epilepsy, schizophrenia, and migraine headaches were once considered functional disorders, but are no longer generally classified that way.[1]
