[Dissociative identity disorder in adolescents: From self-diagnosis to transient illness].

The category of dissociative identity disorder (DID) has puzzled medical science and fascinated popular culture for almost 200 years. Its occurrence in young people raises at least two new questions addressed by science studies and embedded philosophy: self-diagnosis (related to cyberchondria and mass media-induced illness) and transient disease (related to looping effect and identity claim specific to adolescence). In an attempt to refine the sociocognitive model, we analyze the impact of these notions in understanding the local ecological niche in which contemporary adolescent DID occurs.
