Current advances in the language research of patients with Tourette syndrome

Tourette syndrome (TS) is a neurodevelopmental disorder which onset in childhood, with an incidence of 0.6% to 1%, and the ratio of the number of boys to girls of 3 to 4. This disease can cause great effects on learning, social interaction, quality of life and psychological conditions but its symptoms may be easily ignored by parents. Many people misunderstand that TS patients can recover without treatment, which then delays diagnosis and therapy, and cause difficulty in treatment. Language is a direct and convenient method to identify and assess the disease. The present paper conducted a systematic literature review to summarize vocal tics, fluency disorder and non-tic language, and its findings may be helpful for domestic development of clinical linguistics.
