Oppositional defiant disorder (ODD) is a childhood disorder described by the Diagnostic and Statistical Manual of Mental Disorders (DSM) as an ongoing pattern of anger-guided disobedience, hostility, and defiant behavior toward authority figures that goes beyond the bounds of normal childhood behavior. Children suffering from this disorder may appear very stubborn and often angry. A diagnosis of ODD cannot be given if the child presents with conduct disorder (CD).[1]
