Someone here on this board recommended the schwablearning.org site, ( I wish I knew who , so I could thank them ) On this site there is a great article by Dr.Berkley on AD/HD , it was under adhd diagnosis. the Article is 40 pages of pdf file, but it is informative on every aspect a parent could ask for. There are even classroom strategies as well, I am sharing the article with my son's teacher to help her understand him. I certainly have a much better picture now.
