My husband wasn't diagnosed as a child, but it's very evident to me that he has some kind of reading disability that the chaotic NYC public schools of the 70's didn't identify. He told me he was functionally illiterate till he was 17 and became interested in science fiction. He is much, much better today than when I met him, but I'm not sure he reads passively, at least under stress, even though he reads a lot. So, I agree with pp's that it may be a lifelong process. Good luck!
