Simple tics are sudden, brief movements that involve a limited number of muscle groups.
They occur in a single or isolated fashion and are often repetitive. Sometimes people with TS can suppress their tics for a short time, but the effort is similar to that of holding back a sneeze. Eventually the tension mounts to the point where the tics escapes. In most cases, tics decrease remarkably during sleep. Gender also plays an important role in TS gene expression.
