Conduct disorder (CD) is a mental disorder diagnosed in childhood or adolescence that presents itself through a repetitive and persistent pattern of behavior that includes theft, lies, physical violence that may lead to destruction, and reckless breaking of rules,^[1] in which the basic rights of others or major age-appropriate norms are violated. These behaviors are often referred to as "antisocial behaviors",^[2] and is often seen as the precursor to antisocial personality disorder; however, the latter, by definition, cannot be diagnosed until the individual is 18 years old.^[3] Conduct disorder may result from parental rejection and neglect and can be treated with family therapy, as well as behavioral modifications and pharmacotherapy.^[4] Conduct disorder is estimated to affect 51.1 million people globally as of 2013.^[update][5]
