While it initially included only the infliction of harmful medical care, the term has subsequently been extended to include cases in which the only harm arose from medical neglect, noncompliance, or even educational interference. The term is derived from Munchausen syndrome, a psychiatric factitious disorder wherein those affected feign disease, illness, or psychological trauma to draw attention, sympathy, or reassurance to themselves. Munchausen syndrome by proxy perpetrators, by contrast, are willing to fulfill their need for positive attention by hurting their own child, thereby assuming the sick role onto their child, by proxy. These proxies then gain personal attention and support by taking on this fictitious "hero role" and receive positive attention from others, by appearing to care for and save their so-called sick child. They are named after Baron Munchausen, a literary character based on Hieronymus Karl Friedrich, Freiherr von Münchhausen (1720–1797), a German nobleman and well-known storyteller. In 1785, writer and con artist Rudolf Erich Raspe anonymously published a book in which a fictional version of "Baron Munchausen" tells fantastic and impossible stories about himself, establishing a popular literary archetype of a bombastic exaggerator.
