Language in differential diagnosis of a teenage schizophrenic girl with aspects of multiple personality.

Diagnosis of a teenage schizophrenic girl showed many features of her language and behavior mimicked the presentation of a Dissociative Personality Disorder. These aspects were secondary to the primary schizophrenic disorder and treated via a multimodal approach combining pharmacotherapy, individual, family, and milieu therapy. Implications are drawn for tailoring verbal interventions to such overdetermined conditions.
