Okay, let me say that all my teachers thought I was (then) ADD because I could not stay on task. I also did very well in school. Went through testing, and it turns out, I was no where near ADD, but I was bored because my IQ was high and I was flying through the work ahead of my peers and was bored and trying to stimulate my brain in any way I could. So my first suggestion is try IQ testing. (p.s. most of those who have high intellegence have also have poor handwriting because we think faster than we can write, so we are rushing to get through the writing to get the idea down.)
I have worked in social service and I feel that ADHD is WAY too over diagnosed. If a child is energetic, then they must be ADHD. There are cases in new york state where kids were forced on medication then tested later to find out, they were not ADHD.
Also a tip you can use is to listen to her sleep. If she is snoring, then that might be your key. Some cases of ADHD have been traced back to sleep. When they snore, they often snore loud enough to wake themselves up a few times a night causing a lack of sleep and the behaviors are actually from being overtired. (Think about it, don't the behaviors mimic someone who is overtired and trying to keep themselves awake. If they sit still for one second they will proabably be out.) The rememdy to this is to keep track of her snoring, and then take it to your psych (if you do not have one, then the diagnosis is definitely suspect), or your PCP. Ask for a sleep study. If she shows this snoring or sleep apnia, they will remove tonsils and adnoids and you will find that the undesireable behaviors will dissappear. If you want the supporting studies, I will find and forward to you.
Ritalin is not as affective as it is told to be, and any anti-depressants, anti-anxiety medications have not been tested long term on the developing brain and are dangerous.
Good luck, and stick to your guns. Your daughter might not have any learning disability, she may have dyslexia, or she might be overly tired. Until you get a definitive diagnosis stick to your instict about not giving her any meds.
