Breaking the Stigma: A Systematic Review of Antipsychotic Efficacy in Children and Adolescents with Behavioral Disorders

Background/Objectives: Oppositional defiant disorder (ODD) and conduct disorder (CD) are important behavior disorders in children and adolescents, often linked with long-term psychosocial problems. Antipsychotics are frequently prescribed to manage severe symptoms and improve behavior, but their efficacy in this population is still unclear and a lot of physicians are remittent in prescribing them. This systematic review aims to assess the effectiveness of antipsychotic treatment in reducing symptoms associated with ODD and CD in children and adolescents. Methods: Studies that investigated how effective antipsychotic treatments are for children and teens diagnosed with oppositional defiant disorder (ODD) and conduct disorder (CD) were reviewed. Only studies that met a few main criteria were included: participants were between 5 and 18 years old with an ODD or CD diagnosis; the treatment could be any type of antipsychotic, whether typical or atypical; the accepted study designs were randomized controlled trials (RCTs), cohort studies, systematic reviews with meta-analysis, or observational studies. The outcomes of interest were reductions in aggressive or defiant behaviors, improvements in social functioning, and the occurrence of any adverse effects from the medications. There was no restriction on the language of publication, and studies published from 2000 to 2024 were considered. Studies that focused only on non-antipsychotic drugs or behavioral therapies, as well as case reports, expert opinions, and non-peer-reviewed articles did not meet the inclusion criteria. Results: The review consisted of 13 studies. The results suggest that some antipsychotic drugs—especially atypical antipsychotics—can substantially reduce aggressive and defiant behavior in children and adolescents who have oppositional defiant disorder (ODD) or conduct disorder (CD). Common side effects of these medications include weight gain, sedation, and metabolic problems. Conclusions: Although adverse effects are a concern, the potential of these medications to manage disruptive behaviors should not be overlooked. When used in combination with behavioral therapy and other forms of treatment, antipsychotics can markedly improve the outcomes of these very difficult-to-treat patients. Clinicians who treat these patients need to consider antipsychotics as a serious option. If they do not, they are denying their patients medication that could greatly benefit them.
