My son was diagnosed with ADHD at 5. He went on meds immediatly after that and has been since current age of 10. Meds are always a problem to get doseing right,80mgs ritilin, adderall don't remember dose, now doseing changed to concerta 36mgs (2)(76mgs) in the morning.With all the different doseing i have tried, the meds seem to stop working in 2-4 weeks. 72mgs of concerta daily seems to work but what if there is something else wrong?? What if there is something physical, like brain disorder. He has such problems in sentence comprehension, spelling word,forgetting info almost immediatly,angry feelings, frustration to the point of clenching fists and refusing to participate with the class room. I have worked daily with him, with math, i have told him over and over and over 6+6=12 and he still uses his fingers. I know with ADHD repeating things over and over is usually the key but it's almost as if he really can't retrieve the info in his brain,like something is stopping it. So thats my question, could it NOT be ADHD but something else and what could it be ,if so ,What kinds of Dr. do i see, and also What about all this meds?? Can it someday hurt him, the strongness of mgs?? Prozac, cloudidine, zyprexa,were also added to help him. But none of seems to work. He is so anxious without meds, i have tried to not give him any meds but he is so hyper. pls help!! What should i do?? I want him to do well in school and in life.
