Comment: Was the above patient unique? I don't know, since my experience is limited. All I know is that multiple personality is a diagnosis that is often missed [as I often did during my first twelve years as a psychiatrist, because, like most psychiatrists, I had never been taught its typically camouflaged presentation].
