Consecutively ascertained prepubertal & early adolescent bipolar disorder (with or without comorbid attention deficit hyperactivity disorder) outpatients (n=93) were blindly assessed by research nurses. No significant differences were found by gender, puberty, or comorbid attention deficit hyperactivity disorder on rates of mania criteria, mixed mania, psychosis, rapid cycling, suicidality, or comorbid oppositional defiant disorder, with few exceptions. Findings support the prepubertal & early adolescent bipolar disorder phenotype is homogeneous except for differences that mirror normal development. (23 refs.)
