Objectives :The goals of the present study are to assess children with tic disorders, their clinical characteristic and to prove the effectiveness of herbal treatments of tic disorders. Methods :The present study was conducted from January 2006 to April 2011, with 200 out-patient children between the age of 6 to 12 diagnosed with tic disorder (after excluding 10 children who could not be clearly diagnosed) at the "H’herbal medicine clinic located in Seoul. Of these 200 children, we have evaluated the epidemiology and clinical manifestation,and analyzed the results of herbal medicine treatments. Results :1. Among the children diagnosed with tic disorder, TTD was most prevalent (43.3%) and males were more likely than females to express tics (5.45:1). Children with TD sought help significantly later (average age of 9.03 years) than the other types. 2. The analysis results of herbal medicine treatments are as follows. Compared to the pre-treatment assessment, children who received herbal medicine treatment for more than three months (n=52) showed a marked decrease in symptoms of motor tics (the number of motor tics, frequency, severity, complexity) and vocal tics (the number of vocal tics, frequency, severity), in the impairment level of combined tics (motor and vocal tics together)and in the overall score. Conclusions :In conclusion, we apprehended demographic and clinical characteristics of tic disorder patients who visited a Korean traditional medicine clinic by analyzing the psychological assessment results. Furthermore, we identified the effectiveness of herb formula in tic disorder.
