Oppositional Defiant Disorder (ODD) is a childhood behavioral disorder characterized by a persistent pattern of angry or irritable mood, argumentative or defiant behavior, and vindictiveness toward authority figures. It is more than occasional disobedience or temper tantrums that are common in children. In ODD, these behaviors are frequent, persistent, and severe enough to interfere with social, academic, and family functioning. The disorder usually begins during the preschool or early school years and, if left untreated, may progress to more serious behavioral disorders such as Conduct Disorder. According to diagnostic guidelines, the symptoms of ODD must be present for at least six months and involve interactions with at least one person who is not a sibling. Common symptoms include frequent loss of temper, being easily annoyed, persistent anger and resentment, arguing with adults, actively refusing to comply with rules, deliberately annoying others, blaming others for one's mistakes, and displaying spiteful or vindictive behavior. These behaviors occur more often than expected for the child’s developmental level and significantly impair relationships and daily functioning. The exact cause of ODD is not fully understood, but it is believed to result from the interaction of biological, psychological, and environmental factors. Genetic predisposition, abnormalities in brain functioning related to emotional regulation, and neurotransmitter imbalances may contribute to the disorder. Psychological factors include poor emotional regulation, low frustration
