Introduction Tourette Syndrome, a widely misunderstood neuropsychiatic disorder. The varied symptoms of TS can be divided into motor, vocal, and behavioral manifestations Simple motor tics are fast, darting, meaningless muscular events . They can be embarrassing or even painful (such as jaw snapping)., Vocal tics extend over a similar spectrum of complexity and disruption as motor tics. With simple vocal tics, patients emit linguistically meaningless sounds or noises, such as hissing, coughing, or barking. Complex vocal tics involve linguistically meaningful words, phrases, or sentences, e.g., symptoms may interfere with the smooth flow of speech and resemble a stammer, stutter, or other speech irregularities. The most socially distressing complex vocal symptom is coprolalia, the explosive utterance of foul or "dirty" words or more elaborate sexual and aggressive statements. Some TS patients may have a tendency to imitate what they have just seen' heard, or said. For example, the patient may feel an impulse to imitate another's body movements, to speak with an odd inflection, or to accent a syllable just the way it has been pronounced by another person. As well as tics, there are a variety of behavioral and psychological difficulties that are experienced by many, though not all, patients with TS. Those behavioral features have placed TS on the border between neurology and psychiatry, and require an understanding of both disciplines to comprehend the complex problems faced by many TS patients. many TS patients also have obsessive-compulsive  symptoms . There is recent evidence that obsessive-compulsive symptomatology may actually be another expression of the TS gene. Up to 50% of all children with TS who come to the attention of a physician also have attention deficit hyperactivity disorder .
