The combined type of ADHD is actually the most common among ADHD sufferers. They are also the individuals most at risk for other negative problems in their lives due to the nature of the disorder. First of all, children with Combined Type ADHD have higher rates of conduct disorder. Parents who have a child with this type must constantly be on the lookout for problems in other arenas of their lives besides specific symptoms of ADHD. Just keep in mind that problems in the emotional, psychological and social domains are a result of a response to having ADHD, and not the disorder itself. The way your child acts can be changed with time and work.
