It is easy to cause damage to patients' social function and quality of life，especially in the children with TS.Evaluation should take multiple sources of information into consideration，combining direct observation and past information and including general information，symptom interviews，and severity assessment. The Yale Global Tic Severity Scale（YGTSS）is commonly used in clinical practice.Diagnosis is based on clinical manifestations，with attention toexcluding pseudo-refractory tic disorders. Comprehensive and thorough evaluation，early diagnosis，and comprehensive treatment are essential ways to improve patients' quality of life.
