factitious disorder
in DSM–IV–TR, a disorder in which the patient intentionally produces or feigns physical or psychological symptoms solely so that he or she may assume the sick role. Physical symptoms may include pain, vomiting, blackouts, seizures, or infections (see Münchausen syndrome). Psychological symptoms may include depression, suicidal thoughts following the (unconfirmed) death of a spouse, hallucinations, or delusions. DSM–5 defines the disorder similarly but divides it into two subtypes characterized by (a) the falsification of symptoms or induction of injury or disease imposed on oneself, and (b) the same deceptions or harm imposed on others (e.g., a dependent). The latter is a proxy disorder that is synonymous with Münchausen syndrome by proxy. Compare malingering.
