Oppositional Defiant Disorder

The cause of oppositional defiant disorder is unknown but likely involves a combination of genetic and environmental factors. Symptoms generally begin before a child is eight years old. 

Oppositional defiant disorder (ODD) is a childhood behavior disorder defined by a persistent pattern of hostile, vindictive, and defiant behavior toward authority figures. Children with ODD are frequently irritable, argumentative, and disobedient. ODD may be diagnosed if this behavior lasts 6 months or longer.
