Objective: To assess the impact of comorbid autism spectrum disorders (ASD) on the response to second-generation antipsychotics (SGA) in pediatric bipolar disorder (BPD).

Method: Secondary analysis of identically designed 8-week open-label trials of SGA monotherapy (risperidone, olanzapine, quetiapine, ziprasidone, or aripiprazole) in youth with BPD.

Results: Of the 151 BPD subjects 15% (n = 23) met criteria for comorbid ASD. There were no differences in the rate of antimanic response (YMRS change ≥30% or CGI-Improvement ≤2: 65% vs. 69%; p = 0.7) in the presence of comorbid ASD.

Conclusion: No difference observed in the rate of antimanic response or tolerability to SGA monotherapy in the presence of ASD comorbidity.
