Prevalence of some level of conduct disorder is about 10%. Onset is usually during late childhood or early adolescence, and the disorder is much more common among boys than girls.

Symptoms and Signs of Conduct Disorder
Children or adolescents with conduct disorder lack sensitivity to the feelings and well-being of others and sometimes misperceive the behavior of others as threatening. They may act aggressively, by bullying and making threats, brandishing or using a weapon, committing acts of physical cruelty, or forcing someone into sexual activity, and have few or no feelings of remorse. Sometimes their aggression and cruelty is directed at animals. These children or adolescents may destroy property, lie, and steal. They tolerate frustration poorly and are commonly reckless, violating rules and parental prohibitions (eg, by running away from home, being frequently truant from school).
Aberrant behaviors differ between the sexes: Boys tend to fight, steal, and vandalize; girls are likely to lie, run away, and engage in prostitution. Both sexes are likely to use illicit drugs and have difficulties in school. Suicidal ideation is common, and suicide attempts Suicidal Behavior in Children and Adolescents Suicidal behavior includes completed suicide, attempted suicide (with at least some intent to die), and suicide gestures; suicidal ideation is thoughts and plans about suicide.

Diagnosis of Conduct Disorder
Diagnostic and Statistical Manual of Mental Disorders, Fifth edition (DSM-5-TR) criteria
Conduct disorder is diagnosed in children or adolescents who have demonstrated ≥ 3 of the following behaviors in the previous 12 months plus at least 1 in the previous 6 months:
Aggression toward people and animals
Destruction of property
Deceitfulness, lying, or stealing
Serious violations of parental rules
Symptoms or behaviors must be significant enough to impair functioning in relationships, at school, or at work.
Treatment of Conduct Disorder
Medications to treat comorbid disorders
Sometimes placement in a residential center
Treating comorbid disorders with medications and psychotherapy may improve self-esteem and self-control and ultimately improve control of conduct disorder. Medications may include stimulants, mood stabilizers, and atypical antipsychotics, especially short-term use of risperidone.
Moralization and dire admonitions are ineffective and should be avoided. Individual psychotherapy, including cognitive therapy and behavior modification, may help. Often, seriously disturbed children and adolescents must be placed in residential centers where their behavior can be managed appropriately, thus separating them from the environment that may contribute to their aberrant behavior.
Prognosis for Conduct Disorder
Usually, disruptive behaviors stop during early adulthood, but in about one third of cases, they persist. Many of these cases meet the criteria for antisocial personality disorder Antisocial Personality Disorder (ASPD) Antisocial personality disorder is characterized by a pervasive pattern of disregard for consequences and for the rights of others. Diagnosis is by clinical criteria. Treatment may include cognitive-behavioral... read more . Early onset is associated with a poorer prognosis.
Some children and adolescents subsequently develop mood or anxiety disorders, somatic symptom or related disorders, substance-related disorders, or early adult–onset psychotic disorders. Children and adolescents with conduct disorder tend to have higher rates of physical and other psychiatric disorders.
Children with conduct disorder repeatedly act aggressively, violating the rights of others and/or societal norms or rules; they have few or no feelings of remorse.
Disruptive behaviors continue into adulthood in about one third of patients; many of these cases then meet the criteria for antisocial personality disorder.
