factitious disorder

Explanation:

factitious disorder is a condition in which an individual, without any motive, acts as if they are sick by deliberately producing, feigning, or exaggerating symptoms, purely to attain (for themselves or for another) a patient's role. People with a factitious disorder may produce symptoms by contaminating urine samples, taking hallucinogens, injecting fecal material to produce abscesses, and other similar behaviour. It is also called Munchausen syndrome

Factitious Disorder

Explanation:

A factitious disorder is a condition in which a person, without a malingering motive, acts as if they have an illness by deliberately producing, feigning, or exaggerating symptoms, purely to attain (for themselves or for another) a patient's role. People with a factitious disorder may produce symptoms by contaminating urine samples, taking hallucinogens, injecting fecal material to produce abscesses, and similar behaviour.

Criteria for diagnosis includes intentionally fabricating to produce physical or psychological signs or symptoms and the absence of any other mental disorder. Motivation for their behavior must be to assume the "sick" role, and they do not act sick for personal gain as in the case of malingering sentiments. When the individual applies this pretended sickness to a dependent, for example a child, it is often referred to as "factitious disorder by proxy"
