e way in which the brain produces neurotransmitters, which control how signals are sent along the nerve cells. One possible cause is the abnormal metabolism of the neurotransmitters dopamine and seratonin. Usually dopamine helps control inappropriate impulses to move or speak, but, in this case, the dopamine receptors do not work properly. Because of this, impulses to move or speak are not suppressed, resulting in verbal and motor tics (Burleigh, 100). Other studies have considered noradrenaline to be the most important stimulant associated with Tourette's. These conclusions were made when researchers found that medications that mimic noradrenaline may cause tics in susceptible patients (Cramer 1).
             The symptoms of Tourette Syndrome can be classified as mild, moderate, or severe based on their frequency, complexity, and the degree to which they cause impairment or disruption of the patients' ongoing action and daily life. Although this disorder may impair a patient socially or physically, it does not impair thinking or intelligence.
             The main symptoms of Tourette Syndrome are motor, vocal, and mental tics, which tend to get better and worse in cycles. The most common initial symptom is a facial tic, and others follow. Contrary to popular belief, the tics associated with Tourette's are not completely involuntary. They are not spasms, but strong urges to make a certain motion or sound (Cramer, 1). The longer the urge to carry out an action is suppressed, the stronger the outburst becomes. Symptoms of the disorder generally do not appear until about 6 years of age (Burleigh 101).
             Motor tics are repeated, jerky, stereotyped, purposeless muscle movements in any part of the body, that o
