Risperidone for children with attention-deficit/hyperactivity disorder and severe behavioral dysregulation: a randomized placebo-controlled assessor-blinded trial

Background

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in childhood, and treatment of children with severe behavioral dysregulation remains challenging. This study evaluated the efficacy and safety of adjunctive risperidone specifically in children with ADHD and clinically significant behavioral dysregulation - including irritability, impulsive aggression, and oppositional symptoms - refractory to behavioral intervention alone.
