So, do some kids have ADHD but have the ability to focus well when by themselves? Because DS is more affected by environmental distractions over spacing out or just drifting.Um-- I have no real experience directly with ADHD children, but I can tell you that HG people with over-excitability, or just people with sensory sensitivities.... most certainly DO have a great deal of trouble with environment this way.
Make the environment better, and the "ADHD" magically vanishes.
Oh, and I second what Polarbear says about one's mind. I hardly miss mine at all now.
