Yes! This does happens to me. Like pressing a key on keyboard extra times or “stuttering” a normal motion. It’s hypothesized that Tourette’s Syndrome and Stuttering are both some sort of neurological dysfunction in the basal ganglia region of your brain. It happens to me every so often and it is these moments I really empathize with the Tourette’s crew. I can feel my brain randomly make my whole body do something it for sure doesn’t need to, again. I mean take it with a grain of salt. It’s also proposed that a stutter is caused by over activity in the right hemisphere of your brain. Or not enough blood flow to your brocha’s area. Historically, it was something defective with your tongue, throat, or voice box and of course the ol’ it’s “psychological”. I’ve been meaning to write up something about the lack and ever changing science on the causes of stuttering for some feedback but haven’t gotten around to it yet. Anyway, you are not alone!
