I guess my first question is, Is he inattentive and active in other places besides school? Is he just as active at home, in the store, at church, at Grandma's? BEcause ADD/ADHD doens' happen just in school. If it's only confined to that setting, then I would believe that ADHD is not the problem, but there might be learning disabilities. My second questions would be, Who has diagnosed him? A child psychiatrist? A teacher? BEcause it's really not the school's purview to diagnose a neurological disorder. And they sure as heck can't require you to give him medications.
While the stimulant meds that are used to treat ADD/ADHD can be very helpful, they can also have serious side effects. My oldest has severe ADD w/learning disabilities. He couldn't sit still ANYWHERE. And he didn't learn to read until he was 8--third grade! But once he matured a little more he turned into a good reader. His learning disability is not in language arts, however, it's math--he excels in reading and writing.
John took Ritalin, Adderall, and Strattera. Ritalin worked the best for him, but it took his appetite away completely. He ate breakfast, took his pill, and never ate again until his meds wore off around 8pm. I chose to give him med breaks just so he could catch up on growth. Adderall worked well at low doses, but the higher doses that he needed to concentrate in school caused him to be extremely angry and explosive. Strattera did absolutely nothing.
The thing that worked best for John was homeschooling. Really! I took him out of school in third grade and taught him to read and write. He couldn't sit down so he stood at the table and rocked from foot to foot for an entire year (and that was WITH ritalin.) We found that in the home setting he needed far less medication and he was a lot less distractible. I'm not saying thats what your grandson needs, but it was the answer to our prayers. In fact, John did go back to school a few times,but he always ended up returning to homeschool to catch up. He ultimately graduated from homeschool and went to college for 2 years. He still has ADD,although he no longer takes meds because he doesn't like the way they make him feel. But he uses ADD to his advantage writing music, producing plays in community theater, working with computers. Anything that doesn't involve a lot of math.
