Does your teenager rebel against authority figures? He must have ODD!

if your child or teen has a persistent pattern of tantrums, arguing, and angry or disruptive behaviors toward you and other authority figures, he or she may have oppositional defiant disorder (ODD). As many as one in 10 children may have oppositional defiant disorder in a lifetime.

But it's OK ... there's help!
Treatment of oppositional defiant disorder involves therapy and possibly medications to treat related mental health conditions.
I'd say it's a bit odd.
