I am sure that if they had had all the fancy diagnoses for things when I was a kid, I would have had them all. There were a number of things that I did as a kid that drove my mother batty. One of them was eyerolling, I remember well. As far as I know, it was just a habit, and it eventually went away. I remember a long time when I made this little noise in my throat to "test" my voice, while I was reading or whatever, that my mom continually tried to make me stop. I would trace patterns in my head, moving my fingers to the pattern. I chewed on my hair. I can't even remember them all, but they went away and weren't anything important, I guess.
God only knows what I would be diagnosed with these days!
I recently had a weird thing going on with my eyes where I was squinting at things all the time like trying to focus hard, for no reason, and blinking hard all the time. And it made my head hurt. I figured out that it was just plain stress. I'm not the sort to get stressed out, but I was freaking about my job going away and having nothing to back it up, and I guess it just turned into a physical reaction. It's mostly gone now that I have a new job.
So I'd say don't worry too much about the eyerolling--it will probably wander off and be replaced by something equally annoying.
