It's tough to say, since I really wasn't paying attention to them. Truth is I think I was trying to work through them, ignore them. I used to act with a small dinner theatre group. I never had a problem memorizing my lines. Several years after my diagnosis, I attempted to perform in a play. Fortunately I played a reporter, so carrying a notebook (with my lines and blocking) looked like nothing more than a prop. I couldn't remember my lines long enough to make it through the first half of a scene. Memory, anger, and motivation issues, plus others probably became problematic almost immediately after the concussion. Looking back, it explains so much. Wish I'd started looking into it earlier.
