Schizophrenia in adolescent twins: a case study.

Studies of schizophrenia in twins have historically influenced the psychiatric world in shifting the focus of the etiology of psychiatric disorders from a psychodynamic to a genetic one. Although twinning is as frequent a phenomenon as schizophrenia, clinical issues relating to the development of twins and treatment of psychiatrically sick twins are relatively infrequent in the literature. This article presents the treatment of adolescent schizophrenic twins, and focuses on specific developmental, educational and therapeutic issues that must be considered when treating twins. The recent treatment of identical schizophrenic twins has allowed us to review the literature and revisit some of these issues.
