Oppositional Defiant Disorder or ODD is one of the many diagnoses under the umbrella of autism spectrum disorders. This disorder manifests itself as a pattern of angry, irritable, defiant, nonaggressive yet vindictive behavior. Teens especially tend to refuse to comply with rules and restrictions.
And a great many children with ADHD ultimately adjust. Some -- about 20% to 30% -- have learning problems that ADHD treatment may not help, though. As they grow older, some teens who've had the disorder since childhood may have periods of anxiety or depression. When there are more demands at school or home, symptoms of ADHD may get worse. A child with hyperactive behavior may get symptoms of other disruptive disorders, like oppositional-defiant disorder.
