Agreed. Add to this, the changing technology of the world, and randomness of TV, video games, and the way our lives have changed from being routine to being totally random - it's no surprise people (and especially kids) are distracted! Add to that the lack of going outside to play, walking to school, or playing sports. I'm distracted too. Imagine the sensory overload of a 5 or 6 year old.That is why some have problems with how ADHD seems a catch all for what used to be called being a boy. A pediatrician who sees a person once every couple of months, even if he suspects the child is ADHD, cannot truly diagnose the child in the span of a 15 minute contact. Yet, they do. Go figure. (In other words, I don't even think a pediatrician who did not diagnose the thing could be sued for malpractice absent a lot more facts.)
If we NEVER teach our kids to focus, then why wouldn't we expect hyper, random kids. I think the point it becomes diagnosable, is where medication truly has a benefit, not just a sedation effect. We've all seen the poor zombie child, and that poor kid was never meant to be medicated.
