Gilles de la Tourette’s Syndrome and Tic Disorders
Tics can be characterized as repenitive, usually rapid and brief darting movements (motor tics) or sounds made through the nose, mouth, or throat (vocal tics). Unlike many other movement disorders, tics are not constantly present and naturally wax and wane. The disorder can be very severe for short periods and then abate and even transiently disappear. Exacerbation of tic activity can occur when the patient is anxious, excited, or sleep-deprived. However, tics tend to decrease when the patient is involved in a focused activity and become more prominent during relaxation. Whereas any body part can be affected, the eyes, face, and neck are the most common areas of tic involvement. An important characteristic of tics is voluntary suppression, and patients, especially adults, can often keep their tics suppressed for minutes at a time.
