A Wisconsin woman is suing her former psychiatrist for malpractice. Nadean Cool alleges her doctor convinced her she had 120 personalities. Dr. Kenneth Olson reportedly billed Ms. Cool's insurance company for group therapy since he had to deal with some of the personalities individually. Cool charges that her $300,000 treatment left her suicidal and haunted by false memories. Among the myriad personalities Olson detected were Satan and a duck.
