Conduct disorder

Overview


Plain-Language Overview

Conduct disorder is a mental health condition that affects children and adolescents, involving persistent patterns of behavior where the individual violates social norms and the rights of others. It primarily impacts the behavioral and emotional regulation systems of the brain, leading to difficulties in controlling impulses and emotions. People with this disorder may show aggressive behavior, such as bullying or fighting, and may engage in destructive acts like vandalism or theft. These behaviors can cause significant problems at school, home, and in social settings. The condition can affect overall health by increasing the risk of injury, legal issues, and difficulties in relationships.

Clinical Definition

Conduct disorder is characterized by a repetitive and persistent pattern of behavior in children or adolescents that violates the basic rights of others or major societal norms. The core pathology involves impairment in emotional regulation and impulse control, often linked to neurodevelopmental and environmental factors. It is associated with increased risk for antisocial personality disorder in adulthood. The disorder manifests as aggression to people and animals, destruction of property, deceitfulness or theft, and serious violations of rules. The etiology is multifactorial, including genetic predisposition, adverse childhood experiences, and dysfunctional family environments. Early identification is crucial due to its impact on social, academic, and legal outcomes.
