I'm lucky to never have had seizures but I had a constant muscular ticks when I was a teenager that mostly went away as I became an adult.

My experience is consistent with your theory of neural pathways getting set, with the exception that I still have get repetitive head ticks on multi-day periods of high anxiety. I completely believe that better and more consistent sleep as an adult (outside high-anxiety periods) also has a lot to do with it.

I have weird muscular ticks or tremors that are sudden and then stop generally over and over again in the same muscles - either the bicept or the calf - at times. I haven't figured out if it is related to stress or lack of sleep both of which I struggle with but I can say that it is pretty annoying. Sometimes I wonder if it is foreshadowing for something much less pleasant in the future.
