I think a lot of hyper behavior is related to diet and nutrition. Not just high amounts of sugar but the additives in soda pop and junk food get kids ramped up. Not enough exercise is a factor. The electronic environment leads to overstimulation as well. If I were a parent with a hyperactive kid, I would not be looking to add drugs but looking to subtract some things from the diet and environment.
I agree with you about diet and electronic stimulation...when my 4 year old granddaughter gets too hyper or fresh I put on some soothing music and take out clay or a puzzle and shut off the TV or the computer...sometimes she justs need a peqaceful environment and focused attention...I also teach special needs students in a public middle school in Brooklyn...many of out ADHD kids just need a quiet room and an engaging lesson/ activity to calm down...although I have met several kids over the years who benefited greatly from medication and went off it with the advent of puberty.
