[Conduct disorder and antisocial personality disorders: challenges for treatment in adolescence and young adulthood].

Aggressive behaviour is a typical phenomenon in childhood and adolescence. Aggression is one of the frequent reasons for parents to seek child and adolescent psychiatric and psychotherapeutic treatment. Disorders with increased aggressive behaviour, such as conduct or oppositional defiant disorder, carry an increased risk for long-lasting negative impact on well-being, especially when comorbid with substance abuse or affective symptoms. Barriers for treatment are frequently a lack of insight into consequences and non-compliance with intervention shown by adolescents. In addition, interdisciplinary intervention needs to combine psychiatric and psychotherapeutic interventions as well as complex interventions supported by the youth welfare system, and in particular including families. Further research is needed for the implementation of evidence-based treatments in routine care as well in special populations, such as girls with conduct disorders or youth with substance abuse.
