Dissociative disorders: Recognition within psychiatry and RAINS
As medical students in the 1950s, we learned during the course on psychiatry that there was a rare condition known as hysterical multiple personality, which occurred almost exclusively in young women. My student psychiatric text book stated that:
`Double' and `Multiple' personality are the terms applied when the same individual at different times appears to be in possession of entirely different mental content, disposition and character, and when one of the different phases shows complete ignorance of the other, an ignorance which may be reciprocal. Each `sub-personality' . . . is said to be `dissociated' from the total personality.
