I have had some experience with ADD, ADHD, HG/PG and HG/PG+ADD/ADHD. What I have noticed is that if it is ADD, the medicine will be a noticeable improvement, immediately. In the case of HG/PG if the medication doesn't work, it's probably due to something else. It could be boredom or sensory issues of spectrum type of issue, anxiety, ect. Just being HG/PG can cause anxiety that can manifest in ADHD type of symptoms, like arguing, outbursts, friendship issues etc. If you go the medicine route, you have to be patient and try different doses/meds, but if ultimately you never notice a difference in behavior it's probably not ADHD. Best of luck! It's never easy. :-)
