What Is Anger Disorder?
[Also known as oppositional defiant disorder] The essential feature of oppositional defiant disorder is a frequent and persistent pattern of angry/ irritable mood, argumentative/ defiant behavior, or vindictiveness (Criterion A). It is not unusual for individuals with oppositional defiant disorder to show the behavioral features of the disorder without problems of negative mood. However, individuals with the disorder who show the angry/ irritable mood symptoms typically show the behavioral features as well.*
