Phenomenology of prepubertal and early adolescent bipolar disorder: examples of elated mood, grandiose behaviors, decreased need for sleep, racing thoughts and hypersexuality.

Objective: Children are developmentally incapable of many manifestations of bipolar symptoms described in adults (e.g., children do not "max" out credit cards or have four marriages). To address this issue, our group investigated prepubertal and early adolescent age equivalents of adult mania behaviors.

Methods: Details of the methods appear in the companion article in this issue (Geller et al. 2002a). Subjects had a prepubertal and early adolescent bipolar disorder phenotype (PEA-BP) that was validated by reliable assessment (Geller et al. 2001b), 6-month stability (Geller et al. 2000c), and 1- and 2-year longitudinal diagnostic outcome (Geller et al. 2001a, 2002b).

Results: Examples of elation, grandiosity, decreased need for sleep, racing thoughts, and hypersexuality in PEA-BP subjects were compared to examples in prepubertal normal controls and to examples in late teenage/adult-onset mania. Because it is not intuitive that children can be pathologically happy or expansive, sections on guidelines for differentiating normal versus impairing elation and grandiosity are provided.

Conclusion: Due to the high comorbidity of PEA-BP and attention deficit hyperactivity disorder (ADHD), recognition of mania symptoms that do not overlap with those for ADHD may aid in avoiding both under- and overdiagnosis of child bipolar disorder. A discussion of how "nonoverlapping with ADHD" Diagnostic and Statistical Manual of Mental Disorders (4th ed.) mania symptoms can be useful in the differential diagnosis of irritability is also provided.
