Need Informative Article about ADHD

I am the non-ADD spouse and have read Melissa's book and two of Dr. Hallowell's books. I have finally convinced my undiagnosed husband to also read about ADHD, but he told me he is unable to read an entire book and needs a shortened article.

 

Anyone out there know of any informative, but brief articles that explain ADHD? If not, then I will try to compile excerpts out of the books for him to review.
