This program considers the risks, prevalence, and functional consequences of dissociative disorders, focusing primarily on dissociative identity disorder, dissociative amnesia, and depersonalization/derealization disorder as defined in the DSM-5 TR and the ICD-10 system (F40-F49). These disorders don’t seem as easily distinguished from one another by degree or duration, and the program looks at the larger dissociative symptoms common among this grouping of disorders.
