Anybody familiar with this? My precious 3 year old grandson is being tested for this tomorrow. He's basically fine, but seems stressed when there's lots of noise, and he hates getting his hands dirty like with paint, clay, etc. He's way ahead verbally and plays well with others but only in small groups. He's kind of a loner and not a joiner. He's been tested for Austism, ADHD, etc., and he's ok there. He also loves to crash into things-walls, other kids, and he loves to roll back and forth from one side to the other incessantly. In the old days, my daughter says he'd just have been called "a hyper boy." But, he does have some stress, and we want to find out how we can help him. He is extremely happy most of the time, but quite manic. His Pre-K teachers say he's extremely smart (but of course! ) I'm not actually worried, but I wouldn't be surprised, after reading on the web site about this disorder, that he's got some of it. I just wondered if anyone else has had experience with it. I went to my first source-my FSU-ers!
