Brief Summary:
Yigansan was used in Ming dynasty by Xue Kai as a remedy for restlessness and agitation in children. We expect that the total YGTSS scores of Yigansan-treated subjects will be significantly reduced compared to that of placebo-treated subjects.
Detailed Description:
Tourette's disorder (TD) is a chronic, childhood-onset neuropsychiatric disorder. It is characterized by multiple motor and vocal tics, including involuntary or semivoluntary, sudden, brief, intermittent, repetitive movements or sounds. Yigansan was used in several clinical trials, like dementia, pervasive developmental disorder, schizophrenia and Huntington's disease, with good results. So the investigators choose Yigansan as a Chinese medicine formula in this study. After the participants signed the consent form, they have to stop taking any Chinese medicine or western medicine for treating Tourette's disorder for two weeks and then are randomly assigned to Yigansan group or placebo group. Our hypothesis is that Yigansan will be expected to improve motor tics and vocal tics, and YGTSS scores will decrease after 4-weeks treatments; secondary outcomes are measured by CGI-TS (Clinical Global Impression-Tourette Syndrome) scale and GTS-QOL (The Gilles de la Tourette syndrome-quality of life scale), and the investigators will also proceed the basic research of metabolomics and biochemistry(GOT、GPT、BUN、Creatinine、K+). In order to ensure the relationship of Tourette's disorder and allergic rhinitis, the investigators will detect IgE. Besides, the investigators will collect blood and urine from every child or adolescent when a participant visits our clinic at week 0 and week 4. In order to find these biomarkers related to TD, the investigators will use ELISA kits to detect and quantitate significantly changeable concentration of cytokines associated with YGTSS scores. In addition to specific cytokine targets, the investigators will also find these metabolites involved in TD between two groups before and after taking YGS. The serum and urine samples will be prepared and subjected to LC-MS/MS analysis. In summary of the experimental designs and expected results, the therapy and background information will be more clarified on the therapeutic efficacy and safety by Yigansan treatment for TD. Most importantly, this study will provide a kind of Chinese medicine formula to relieve such a disorder that most doctors feel difficult to treat.
