Disruptive Behavior Disorder includes the following two types: conduct disorder and oppositional defiant disorder. These disorders are characterized by disruptive behaviors such as temper tantrums or physical agression. DBD (either conduct disorder or oppositional defiant disorder) often coexist with ADHD.

Types of Disruptive Behavior Disorder

Conduct Disorder

Conduct disorder is a disorder with a repetitive pattern of behaviors that violate social rules. Individuals with conduct disorder may be agressive toward others or animals, set afire, damage property, steal items, or tell a lie on a consistent basis. Typically, these symptoms start to appear around age 10.

Oppositional Defiant Disorder

Oppositional defiant disorder is a disorder with a persistent pattern of disobedience, hostility, or defiant behaviors toward authority figures. Individuals with oppositional defiant disorder easily get upset and often argue. The onset of these symptoms is usually between age 3 to 8 while some teenagers show similar behaviors during puberty.
