I have ADHD and have never been able to use flash cards for memorization. What I do for things that I need to memorize is to rewrite them as a children's book (with pictures and all). You need to know the material very well to be able to explain it in a way a child can understand. The thing is that I can just jump right into it and I will research as I go to fill in any blanks in the information. By the time it's done, I know the information inside and out.
