Aggressive Behavior in Children and Adolescents With Bipolar Spectrum Disorder: A Systematic Review of the Prevalence, Associated Factors, and Treatment.

OBJECTIVE

Bipolar disorder (BD) in childhood and adolescence is associated with aggressive behaviors, which might be common and in turn associated with poor clinical outcomes. This is the first systematic review to provide a comprehensive view of the current status of the knowledge about aggressive behaviors in youth with BD.

METHOD

We conducted a PRISMA-compliant systematic review of studies investigating aggressive behaviors in children and adolescents with BD (PROSPERO: CRD42023431674). A systematic multi-step literature search was performed on PubMed and the Web of Science. Literature search and data extraction were carried out independently. We provided a systematic synthesis of the findings from the included studies We assessed risk of bias using a modified version of the Newcastle-Ottawa Scale for cross-sectional and cohort studies.

RESULTS

Of the 2,277 identified records 35 were included; mean age was 12.4 years, and 57.1% were male individuals. 7 studies reported on the prevalence of aggressive behavior among BD children and adolescent population, with 5 of them reporting a prevalence of over 69.0%. Aggressive behaviors were more common in children and adolescents with BD than in those with ADHD or depression. Aggressive behaviors were associated with borderline personality disorder features and poor family functioning. Valproic acid received empirical support for its efficacy in reducing aggressive behavior in BD.

CONCLUSION

Aggressive behaviors are prevalent among youth with BD and warrant clinical attention and specific evidence-based management. Further research on prognostic factors and psychosocial interventions evaluated prospectively is required.
