Typical symptoms of motor tics include involuntary (uncontrolled) muscular movements of the mouth or eyes, head twitching, and shoulder shrugging. Examples of less common, complex tic symptoms are bending over to touch the floor, smoothing clothing and jumping. Vocal tics are involuntary expressions, such as noises, words (sometimes obscenities) or repetitive phrases (in some cases with increasing rapidity). Symptoms vary greatly among people with tic disorders, ranging from barely observable tics to severe and incapacitating symptoms.
Tics are rapid sudden movements of muscles in your body. Tics can be vocal, too. Both kinds of tics are very hard to control and can be heard or seen by others. However, some tics are invisible (e.g., toe crunching, building up tension in your muscles). Simple tics involve just one group of muscles and are usually short, sudden and brief movements such as twitching the eyes or mouth movements. Some simple tics can be head shaking, eye blinking or lip biting. Simple vocal tics can be throat clearing, coughing or sniffing.
