Oppositional defiant disorder (ODD) is a behavior disorder in children and teens. They show angry and defiant behaviors much more than most people of the same age. These behaviors interfere with the person’s relationships. It also has an impact on their ability to do well in school, work, and family situations.
The cause of ODD is unknown. ODD may be a mix of genes, family, and social factors.
A chemical imbalance in the brain may be responsible for ODD.
