Objective To investigate the characteristics of TCM syndromes of Tourette syndrome （TS） to find out the basis for its TCM treatment. Methods Based on the preliminary studies

the TCM syndrome scale of TS is designed to investigate the general data

main symptoms and syndromes of 126 cases of TS children to find out the frequency of each syndrome. Results Of the 126 TS cases

97 were males

accounting for 77%; the average age was 8.31 years; and 32 had a positive family history

accountting for 25.4%. In the tic behavior

the facial twitching and limb twitching occupied 91.6% of the muscular stereotyped tic. In the vocal behavior

the throat and nasal sound occupied 42.1%. In the accompanied symptoms

the inattention occupied 69.8%. In the personality offset

the willfulness occupied 49.2%

irritable hyperactivity occupied 78.6%

and silence occupied 7.1%. More than 50% of the patients had red or dark red tongue with thick or sticky coating. Nearly 70% of them had string-taut or rolling pulse. As for the syndromes

heart-liver deficiency with deficiency wind stirred up

and liver-kidney yin deficiency with yang hyperactivity stirring up wind were common

being 41.3% and 34.1% respectively. Conclusion TS takes the heart-liver deficiency with deficiency wind stirred up and liver-kidney yin deficiency with yang hyperactivity stirring up wind as the common syndromes. The basic treating principle is enriching yin and reducing yang

and smoothing the liver to stop wind. At the same time

reinforcing the spleen and nourishing the heart

and dissolving phlegm and enlightening the brain should be applied for treatment.
