Sybil was the first major book to tie "MPD" to child abuse. Published in 1973, it was followed by a compelling 1976 movie. Sybil played a substantial role in the cultural and psychiatric tsunami, later known as the "false" or "recovered" memory debate. According to author Debbie Nathan "In the entire history of Western civilization, there had been less than 200 cases over a period of centuries. But after the book and film, suddenly there were hundreds and thousands. And by the late 1980s there were 40,000 cases diagnosed in the United States alone." See Sybil Exposed
