The most common disruptive behaviour disorders in children include oppositional defiant disorder (ODD), conduct disorder (CD) and attention deficit hyperactivity disorder (ADHD). Treatment can include therapy, education and medication.
These three behavioural disorders share some common symptoms, so diagnosis can be difficult and time consuming. A child or adolescent may have two disorders at the same time. Other exacerbating factors can include emotional problems, mood disorders, family difficulties and substance abuse.
