Oppositional Defiant Disorder ODD
Many children with ADHD display oppositional behaviors at times.
Oppositional defiant disorder is defined in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) as including persistent symptoms of “negativistic, defiant, disobedient, and hostile behaviors toward authority figures.”
A child with ODD may argue frequently with adults; lose his temper easily; refuse to follow rules; blame others for his own mistakes; deliberately annoy others; and otherwise behave in angry, resentful, and vindictive ways.
He is likely to encounter frequent social conflicts and disciplinary situations at school.
In many cases, particularly without early diagnosis and treatment, these symptoms worsen over time—sometimes becoming severe enough to eventually lead to a diagnosis of conduct disorder.
