The origins of factitious disorder
Richard A. A. Kanaan & Simon C. Wessely

10 years ago Carol Morley came to see me to talk about mass hysteria. We discussed my own theories of mass hysteria—the subject of my medical school dissertation and my first “proper” paper. She spent a couple of days in my office rummaging through my collection of accounts about episodes of mass hysteria; I had stopped my previous practice of letting journalists borrow my files since an investigative journalist took home a large box of original documents about the early years of ME, and lost them.
Richard Kanaan and I have been preoccupied with the distinctions between hysteria, Munchausen's syndrome, and malingering. For many years it has been argued that in hysteria the person has no conscious knowledge that their symptoms are not explicable by organic illness, in Munchausen's they do know they are faking but their motives for so doing remain unconscious, and finally in malingering both behaviour and motivation is conscious.
