    Conduct disorder is a childhood emotional and behavioral disorder characterized by disruptive behavior. Children with conduct disorder have difficulty following rules and behaving in a socially acceptable manner.

    While no specific cause of conduct disorder has been identified, the following are thought to possibly contribute to the development of conduct disorder:
    • Brain damage
    • Genetics

  • Risk Factors

    Conduct disorder is more likely in male children younger than 18 years old, usually 7-8 years and older.
    The following factors are thought to increase the risk of conduct disorder:
    • A history of child abuse
    • Poor family functioning
    • Family members with substance abuse problems
    • Failure in school
    • Traumatic life experiences
  • Symptoms

    Symptoms of conduct disorder may include:
    • Bullying behavior
    • Physical fights
    • Use of a weapon
    • Physical cruelty to people or animals
    • Stealing or lying
    • Forced sexual activity
    • Deliberate destruction of property
    • Serious violations of rules
    • Starting fires
  • Diagnosis

    You will be asked about your child’s symptoms and medical history. A physical exam will be done. Your child may be referred to a mental health professional for evaluation. Diagnosis is based on behaviors that violate social norms or the basic rights of others.
  • Treatment

    Talk with your doctor about the best treatment plan for your child. Treatment options include:
    Parent Training
    Experts can help parents learn to manage their child’s behavior and emotional problems.
    Behavior therapy and psychotherapy can help children learn to appropriately express and control their anger.
    Psychiatric medications may benefit children with conduct disorder when used in combination with some form of therapy.
  • Prevention

    If you are concerned your child may be at risk for conduct disorder, talk with your child's doctor about early intervention options.
