Phenomenology and Outcome of Subjects With Early- and Adult-Onset Psychotic Mania

OBJECTIVE: This study examined clinical differences between subjects with early-onset and adult-onset psychotic mania. METHOD: Subjects were from an epidemiologically derived, hospitalized sample who met criteria for definite bipolar disorder after 24 months of follow-up and whose index episode had been manic. Information collected regarding demographic characteristics, psychotic and depressive symptoms, childhood behavior problems and school functioning, substance alcohol use disorders, and episode recurrence for two subgroups were compared: those whose illness first emerged before age 21 (early onset) (N=23) and those whose first episode occurred after age 30 (adult onset) (N=30). RESULTS: A larger proportion of the early-onset subjects were male, had childhood behavior disorders, had substance abuse comorbidity, exhibited paranoia, and experienced complete episode remission less frequently during 24-month follow-up than the adult-onset subjects. CONCLUSIONS: These data add to the body of evidence that has suggested that many subjects with early-onset psychotic mania have a more severe and developmentally complicated subtype of bipolar disorder.
