ODD has a strongly genetic component. It runs in families and several people in the same family may be affected. It often begins in childhood with patterns of rebellion against adults and their rules. Some children with ODD outgrow the condition by age eight or nine. But about half of them continue to experience symptoms of ODD through adulthood. | ODD has a strongly genetic component. It runs in families and several people in the same family may be affected.
