There's a good little adult test on the site here:
http://psychcentral.com/quizzes/adultaddquiz.htm and the scoring is followed with where to find informational articles that are good also. Maybe something will catch your eye there, Max?
My brother's 61 GoodMama, and my sister-in-law swears he's ADD/ADHD :-) I just sent her the test to see if she could test him when he wasn't paying attention, LOL.
