DIAGNOSIS / DISSOCIATION / RESEARCH
Clinical descriptions, contemporary research, and the limits of what we know.
Dissociative Identity Disorder (DID) is a recognized diagnosis in the DSM-5-TR. The World Health Organization also describes dissociative disorders in its ICD-11 framework. Recognition of the condition does not mean every proposed explanation of it has been settled.
This collection is here for curiosity, careful reading, and compassion. Research on DID remains relatively small and methodologically challenging. A paper's conclusions should be evaluated in the context of its methods, sample, and limitations. The lived experience of someone with DID is not a spectacle and not something a bibliography can reduce to a single diagram.
