What I have noticed so far:

Easily agitated
Lowered comprehension
Inability to put thoughts to words - although I have always had a difficulty with that
Used to type 65-70 words per minute, now I find myself always looking at the keyboard, I know where the key is but my hands want to go somewhere else, I guess I would say that is procedural memory
Easy discouragement

I am sure I could come up with more but I am having a bit of a blank moment right now, just looking at the curser blink, which is so discouraging. Maybe they will come to me later.
