B. Geller et al., One-year recovery and relapse rates of children with a prepubertal and early adolescent bipolar disorder phenotype, AM J PSYCHI, 158(2), 2001, pp. 303-305
Objective: The study examined 1-year recovery and relapse rates for mania i
n subjects who met criteria for a prepubertal and early adolescent bipolar
disorder phenotype.
Method: Outpatients identified by consecutive new-case ascertainment were a
ssessed by means of separate child and parent interviews, consensus confere
nces, and blind best estimates. The definition of the prepubertal and early
adolescent bipolar disorder phenotype was DSM-LV mania with elation and/or
grandiosity as one criterion.
Results: Of 93 subjects seen at baseline, 89 were seen at 1 year (95.7% ret
ention). The rate of recovery from mania was 37.1%, and the rate of relapse
after recovery was 38.3%. No covariates were significantly associated with
recovery or relapse.
Conclusions: The low recovery and high relapse rates supported the study hy
pothesis of poor outcomes, which was made on the basis of similarity betwee
n the characteristics of the prepubertal and early adolescent bipolar disor
der phenotype (long episode duration and high prevalence of mixed mania, ps
ychosis, and rapid cycling) and those of severe bipolar disorder in adults.
