- Jean-Martin Charcot (1825 - 1893) : Jean-Martin Charcot concluded that Hysteria was a real disorder, unlike most of the physicians of his day. He theorized the inherited predisposition toward Hysteria could become actualize d when traumatic experience or hypnotic suggestion causes an idea or a complex of ideas to become dissociated from consciousness. Isolated from rational control, such dissociated ideas become powerful enough to cause the symptoms associated with hysteria, for example, paralysis.
