My DS is ADHD. All kids have different symptoms. There is a spectrum and you can be a little ADHD or alot ADHD. We had to fill out the questionaires, we had the bloodwork (and continue to do so yearly), we had interviews etc.
ADHD kids are almost always VERY intelligent. Some have behavioral problems in school (but mine did not). Some are very bored in school (mine was so bored he didn't feel the need to do homework EVER.)
One thing that I also did was write out specific incidences that I thought the doctor needed to know about.....
We called him the Energizer Bunny. He could go on, and on and on BUT I could pick him up, put him in bed and he would be OUT. Like he crashed. He never had real problems sleeping.
When he was little I would try to read a book to him. We may get through the first or second sentence. His brother who is not ADHD would sit with a stack of books and want me to read them all over and over and over again. ( I am not trying to compare my boys just showing the difference.)
In the middle of winter I would have him put his boots and coat on and have him do laps around the house. I would say "A" run 5 laps (as I walked back and forth between the front and back doors waving at him), sometimes he would do 4 and he would tell me that he got his enery out and he didn't need to do more. Other times he would do 6 or 7. Whatever he felt he needed.
One day he was running on the back of the couch, jumping to the ottaman, jumping onto the chair, then back to the couch. He stopped long enough to take his shirt off because he was sweating so bad. When I asked him why he didn't stop, he broke into sobs and said he couldn't.
I would write down any incidences that have happened and bring it with you. It will give the doctor an idea of what is happening in your home.
MY DS is now 15. He is still medicated but the dosage has gone down at his request. He seems to be doing well. He is learning to overcome his ADHD. We have had our good days and bad days. Lots of patience is required but his is a very sensitive, helpful, fun, social, athletic, very smart, young man who makes me proud. I wouldn't want him any other way.
