In your son's case this is very important, since you feel your son may have emotional issues. A thorough work-up by a child psychiatrist, who is familiar with ADHD and other "look alike" conditions, is a must. You ask if defiant behavior is a sign of ADHD or if ADHD can cause emotional issues. The answer to both is sometimes. That's why it's important to have your son seen by someone who is experienced in the art of differential diagnosis. In order to treat the condition properly, it's important to know if your son has oppositional defiant disorder, depression, ADHD, or a combination of these disorders or other conditions. Ask your pediatrician for a referral to a pediatric psychopharmacologist. This is a psychiatrist/MD who is trained in helping you have more confidence in the diagnosis.
