Oneselves: Multiple Personalities, 1811-1981 (Paperback) (ISBN-13: 9780786467198)

In the 1970s some 50 cases of multiple personality were reported; there had been 90 in the previous 150 years. This book presents 28 case histories, from the earliest identifiable case in 1811 to a widely publicized one in the 1980s.

These fascinating histories illustrate a wide variety of symptoms and behavior--the very factors that make diagnosis so difficult. The cases show that the causes of multiple personality disorders can range from deep and complicated psychological traumas to a simple physical injury like a blow to the head. Associated phenomena include chronic sleepwalking, persistent time loss, epilepsy, automatic writing, hallucination and several kinds and degrees of amnesia.
