I agree that ADHD and ADD are way overdiagnosed, and that there are many kids taking meds that shouldn't be. When my son's teacher first suspected it, we took him to our family doctor who literally looked at him (didn't examine him or anything) and said "Well, he looks well adjusted to me, but if the school thinks he needs Ritalin, I'll write the prescription." I took him out of there and we found a pediatrician who spent two hours with him on the first visit. We went to meds as a last resort.
And the first day he went to school with the meds, he came home and said "I did all my math, and it was easy." But by the end of 5th grade, it was no longer working so we took him off the meds. We struggle every night with homework issues.
If we had honestly thought there as another solution, of course we wouldn't have chosen the meds. But we're upper-middle income, suburbia living, church-attending, community supporting, conservative, boy scout den leader, pta board member and stay-at-home mom (then) parents. It was not environmental with him.
