Conduct disorder is a type of behavior disorder. It's when a child has antisocial behavior. They may ignore basic social standards and rules. They may also:

• Be irresponsible
• Skip school or run away (delinquent behavior)
• Steal or do other things to violate the rights of others
• Physically harm animals or other people, such as committing assault or rape

These behaviors sometimes happen together. But one or more may occur without the others.

Experts believe that many factors play a role in conduct disorder. These are:

• Brain damage
• A traumatic event
• Genes
• Child abuse
• Past school failure
• Social problems

Some children with conduct disorders seem to have a problem in the frontal lobe of the brain. This interferes with a child's ability to plan, stay away from harm, and learn from bad experiences.

Some experts believe that a series of traumatic experiences occurs for a child to develop a conduct disorder. These experiences then often lead to depressed mood, behavior problems, and involvement in a deviant peer group.

A conduct disorder is more common in boys than in girls. It's also more likely to develop in children or teens who come from homes that are:

• Disadvantaged
• Dysfunctional
• Disorganized

Children with these mental health problems are also more likely to have conduct disorder:

• Mood or anxiety disorders
• Posttraumatic stress disorder (PTSD)
• Substance abuse
• Attention-deficit/hyperactivity disorder (ADHD)
• Learning problems or learning disorders

Children or teens who are considered to have a difficult temperament are more likely to develop behavior problems.

Most symptoms seen in children with conduct disorder can also be seen at times in children without this disorder. But in children with the disorder, these symptoms occur more often. They also interfere with learning, school adjustment, and relationships with peers and adults.

Each child's symptoms may vary. But the four main groups of behaviors are described below.

• Intimidating behavior
• Bullying
• Physical fights
• Cruelty to others or animals
• Using a weapon
• Forcing someone into sexual activity, rape, or molestation

• Intentionally destroying property (vandalism)
• Arson

• Lying
• Theft
• Shoplifting
• Delinquency

• Not going to school (truancy)
• Running away
• Pranks
• Mischief
• Very early sexual activity

These symptoms may look like other mental health problems. Have your child see a child psychiatrist or qualified mental health expert for a diagnosis.

A child psychiatrist or qualified mental health expert can diagnose a conduct disorder. They will talk with parents and teachers about the child's behavior and may observe the child in different settings. In some cases, your child may need mental health testing.

If you notice symptoms of conduct disorder in your child or teen, or if trusted professionals like teachers express concern, you can help your child by seeking a diagnosis right away. Early treatment can often prevent future problems.

Treatment will depend on your child's symptoms, age, and general health. It will also depend on how severe the condition is.

Treatment for conduct disorder may include:

• Cognitive-behavioral therapy. A child learns how to better solve problems, communicate, and handle stress. They also learn how to control impulses and anger.
• Family therapy. This therapy helps make changes in the family. It improves communication skills and family interactions.
• Peer group therapy. A child develops better social and interpersonal skills.
• Medicines. These are not often used to treat conduct disorder. But a child may need them for other symptoms or disorders, such as ADHD. These other disorders often occur along with symptoms of conduct disorder.

Experts don't know exactly why some children develop conduct disorder. Things such as a traumatic experience, social problems, and biological factors may be involved. To reduce the risk for this disorder, parents can learn positive parenting strategies. They can be good role models for their children. This can help to create a closer parent-child relationship and give the child examples of how to respectfully treat other people, animals, and property. It can also create a safe and stable home life for the child.

Early treatment for your child can often prevent future problems. Here are things you can do to help your child:

• Keep all appointments with your child's doctor.
• Take part in family therapy as needed.
• Take the time to listen to your child and help them express thoughts and concerns to the team members.
• Talk to your child's doctor about other health care providers who will be involved in your child's care. Your child may get care from a team that may include counselors, therapists, social workers, psychologists, teachers, school psychologists, school counselors, school nurses, and psychiatrists. Your child's care team will depend on their needs and how serious the disorder is.
• Work closely with the staff at your child's school. Your child may benefit from an individualized educational plan (IEP) to help them succeed in school.
• Tell others about your child's conduct disorder. Work with your doctor and schools to develop a treatment plan.
• Reach out for support. Connecting with other parents who have a child with conduct disorder may be helpful. Find a support group for caregivers of children with conduct disorder. If you feel overwhelmed or stressed, talk with your doctor about individual counseling.
