Oppositional Defiant Disorder



Oppositional defiant disorder (ODD) is a behavior disorder in children and teens. Those with this disorder show negative, angry, and defiant behaviors much more often than most people of the same age. These behaviors begin to adversely affect the person’s relationships and ability to perform successfully in school, work, and family situations.


The cause of ODD is unknown. Like other psychiatric disorders, ODD results from a combination of genetic, family, and social factors. Children with ODD may inherit chemical imbalances in the brain that make them more likely to have the disorder.
