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
  • Child abuse
  • Genetics
  • Failure in school
  • Traumatic life experiences

Your doctor will ask about your child’s symptoms and medical history, and perform a physical exam. Your child may be referred to a mental health professional, who will evaluate your child.


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 such as lithium, risperidone, and clonidine may benefit children with conduct disorder. In some studies, lithium has helped to reduce aggression. Currently, there are no medications that have shown to be clearly effective in treating conduct disorder.


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

Studies have shown that a parenting program called Webster-Stratton Incredible Years can benefit young children who are at risk for conduct disorder.
