Münchausen Syndrome is a psychiatric factitious disorder wherein those affected feign disease, illness, or psychological trauma with predominantly physical signs and symptoms. People affected by this disorder will also have a history of recurrent hospitalization, and dramatic, untrue, and extremely improbable tales of their past experiences. The motivation for this behaviour is unclear, but it presumably fills a psychological need to feel cared for. Risk factors for developing Münchausen syndrome include childhood trauma and growing up with parents/caretakers who were emotionally unavailable due to illness or emotional problems. In a similar disorder called Münchausen syndrome by proxy, a parent or guardian may fake an illness in a child.
