Are childhood psychiatric histories of bipolar adolescents associated with family history, psychosis, and response to lithium treatment?
OBJECTIVE: To examine if childhood psychiatric diagnoses are associated with family history, psychosis, age, and lithium response. METHOD: Associations among variables, and their contributions to explaining lithium response were examined in 48 bipolar adolescents enrolled in a study of lithium. RESULTS: Presence of a childhood diagnosis was not associated with family psychiatric history or lithium response. Subjects with psychotic features, however, were less likely to have a childhood psychiatric diagnosis, were older, and had a poorer response rate to lithium than subjects without psychosis. DISCUSSION: Heterogeneity within bipolar adolescents may be based on clinical features such as psychosis rather than childhood or family history alone.
