Two or more distinct identities that take over the individual at different times: original personality = host", other personalities = alters". Often host is not aware of alters but the alters know about the host: alters also usually know about each other. # of alters can range 2 to 100+ Alters may be completely different from each other: different speaking style, different gender, different temperament. Pre-1970 did was exceptionally rare: only about 100 cases total reported, since then, numbers have skyrocketed and then shrank again. Possibility for skyrocket more awareness = more easily diagnosed by therapists. Prevalence: 0. 5%-1, more likely in females (9:1 ratio, diagnoses at 20s and 30s mainly.
