Bright child can't retain letter names?

Still sounds like it "could" be some sort of dyslexia (there are 100's of forms). Under this umbrella is dygraphia and a few more I won't even begin to spell. I'll give you an example of what I'm talking about (I have it, so this is 1st hand). I was making a poster. Had the word "The" just like that and wanted to put it all in caps (this was in a wp programs with spell check!). I could not tell what was on the screen! I'm in my 30's, graduated sum cum laude in college, A/B student, 99%tile on tests, and I couldn't read the word THE! It wasn't that I couldn't read it... I literally had no clue what the letters were that were staring back at me! I just shook my head, shut the computer down, and went home! My eyes/brain had had enough for that day! With my son T (age 8, grade 2, severe dyslexia), he cannot remember letters from page to page, moment to moment at times. He's just barely starting to read. It could be other things, but don't dismiss dyslexia.
