My son's school was pushing ADHD and meds (although they couldn't come out and say it directly). We pushed back and did alternatives, but finally tried the meds. Made him worse. We found a doc that specializes in pediactric neurology and she said the stimulants made him worse because he didn't have ADHD, but rather a "mood regulation disorder."
