ADOLESCENT MEDICINE :: Behavior Disorders
What is conduct disorder (CD)?
Conduct disorder is a behavior disorder, sometimes diagnosed in childhood, that is characterized by antisocial behaviors which violate the rights of others and age-appropriate social standards and rules. Antisocial behaviors may include irresponsibility, delinquent behaviors (such as truancy or running away), violating the rights of others (such as theft), and/or physical aggression toward others (such as assault or rape). These behaviors sometimes occur together, however, one or several may occur without the other(s).
What causes conduct disorder?
The conditions that contribute to the development of conduct disorder are considered to be multifactorial, with many factors (multifactorial) contributing to the cause. Neuropsychological testing has shown that children and adolescents with conduct disorders seem to have an impairment in the frontal lobe of the brain that interferes with their ability to plan, avoid harm, and learn from negative experiences. Childhood temperament is considered to have a genetic basis. Children or adolescents who are considered to have a difficult temperament are more likely to develop behavior problems. Children or adolescents from disadvantaged, dysfunctional, and disorganized home environments are more likely to develop conduct disorders. Social problems and peer group rejection have been found to contribute to delinquency. Low socioeconomic status has been associated with conduct disorders. Children and adolescents exhibiting delinquent and aggressive behaviors have distinctive cognitive and psychological profiles when compared to adolescents with other mental health problems and control groups. All of the possible contributing factors influence how children and adolescents interact with other people.
Who is affected by conduct disorder?
Approximately 6 percent of children ages nine to 17 years old have conduct disorders. The disorder is more common in boys than in girls. Children and adolescents with conduct disorders often have other psychiatric problems as well that may be a contributing factor to the development of the conduct disorder. The prevalence of conduct disorders has increased over recent decades. Aggressive behavior is the reason for one-third to one-half of the referrals made to child and adolescent mental health services.
What are the symptoms of conduct disorder?
Most symptoms seen in adolescents with conduct disorder also occur at times in adolescents without this disorder. However, in adolescents with conduct disorder, these symptoms occur more frequently and interfere with learning, school adjustment, and, sometimes, with the adolescent's relationships with others.
The following are the most common symptoms of conduct disorder. However, each adolescent may experience symptoms differently. The four main groups of behaviors include the following:
The symptoms of conduct disorder may resemble other medical conditions or behavioral problems. Always consult your adolescent's physician for a diagnosis.
How is conduct disorder diagnosed?
A child psychiatrist or a qualified mental health professional usually diagnoses conduct disorders in children and adolescents. A detailed history of the adolescent's behavior from parents and teachers, observations of the adolescent's behavior, and, sometimes, psychological testing contribute to the diagnosis. Parents who note symptoms of conduct disorder in their child or teen can help by seeking an evaluation and treatment early. Early treatment can often prevent future problems.
Further, conduct disorder often coexists with other mental health disorders, including mood disorders, anxiety disorders, post-traumatic stress disorder, substance abuse, attention-deficit/hyperactivity disorder, and learning disorders, increasing the need for early diagnosis and treatment. Consult your adolescent's physician for more information.

Prevention of conduct disorder in adolescents:
As with oppositional defiant disorder (ODD), some experts believe that a developmental sequence of experiences occurs in the development of conduct disorder. This sequence may start with ineffective parenting practices, followed by academic failure, and poor peer interactions. These experiences then often lead to depressed mood and involvement in a deviant peer group. Other experts, however, believe that many factors, including child abuse, genetic susceptibility, history of academic failure, brain damage, and/or a traumatic experience influence the expression of conduct disorder. Early detection and intervention into negative family and social experiences may be helpful in disrupting the development of the sequence of experiences that lead to more disruptive and aggressive behaviors.
