DSM-IV mania symptoms in a prepubertal and early adolescent bipolar disorder phenotype compared to attention-deficit hyperactive and normal controls.
OBJECTIVE
To compare the prevalence of Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) mania symptoms in a prepubertal and early adolescent bipolar disorder phenotype (PEA-BP) to those with attention deficit hyperactivity disorder (ADHD) and normal community controls (CC).


METHODS
To optimize generalizeability, subjects with PEA-BP and ADHD were consecutively ascertained from outpatient pediatric and psychiatric sites, and CC subjects were obtained from a random survey. All 268 subjects (93 with PEA-BP, 81 with ADHD, and 94 CC) received comprehensive, blind, baseline research assessments of mothers about their children and of children about themselves. PEA-BP was defined by DSM-IV mania with elation and/or grandiosity as one criterion to ensure that subjects had one of the two cardinal symptoms of mania and to avoid diagnosing mania only by criteria that overlapped with those for ADHD.


RESULTS
Five symptoms (i.e., elation, grandiosity, flight of ideas/racing thoughts, decreased need for sleep, and hypersexuality) provided the best discrimination of PEA-BP subjects from ADHD and CC controls. These five symptoms are also mania-specific in DSM-IV (i.e., they do not overlap with DSM-IV symptoms for ADHD). Irritability, hyperactivity, accelerated speech, and distractibility were very frequent in both PEA-BP and ADHD groups and therefore were not useful for differential diagnosis. Concurrent elation and irritability occurred in 87.1% of subjects with PEA-BP. Data on suicidality, psychosis, mixed mania, and continuous rapid cycling were also provided.


CONCLUSIONS
Unlike late teenage/adult onset bipolar disorder, even subjects with PEA-BP selected for DSM-IV mania with cardinal symptoms have high rates of comorbid DSM-IV ADHD. High rates of concurrent elation and irritability were similar to those in adult mania.
