Uncontrolled head movement, also called spasms, twitch or tic, may not be noticeable to others, unlike the twitch sufferer who is aware of it no matter how slight. Tic occurs due to sudden muscle contraction and relaxation. Medical treatment and lifestyle changes can help contain the disorder.
Everyone should have experienced twitches that affect parts of the body such as eyelids, cheeks, and lips but not limited to these areas only.Muscle fatigue can cause spasms and also a stressed out nervous system, a drug reaction, fatigue, alcohol and even after waking up. I've noticed one more head twitch occurring. And that is due to staring at certain websites on a computer.
There are some sites with so many things going on at the same time it causes one's head to twitch. Moving signs, flashing signs, moving menus, message boxes, ads to the right top and left, sliding flags, sliding signs and then there is the slide bar that your head moves to in unison.
This type of site causes the head or eyes to move left, right, up, down, sideways, diagonally, back and forth. No matter how subtle, head twitches are; will result in an early exit from a site if the tic was brought on by that site.
