The authors describe a neurodevelopmentally relevant, clinically derived model for understanding and treating aggressive behavior in youth. Based on case experience and literature review, the authors divide aggressive behavior into five symptomatic domains with respective neurobiological/neurodevelopmental underpinnings. These five symptom domains (impulsivity, affective instability, anxious/hyperarousal, cognitive disorganization, and predatory aggression) emerge as logical and clinically useful targets for treatment. The authors aim to establish a relationship between these symptom domains and brain structure and function that offers a clinically relevant approach to the complexities of understanding aggression and its treatment.
