“…In addition, many clinicians erroneously believe that coprolalia must be present for the diagnosis to be made, and the diagnosis is still not made fairly frequently by inexperienced clinicians. It is well known that many patients with GTS have attracted a wide variety of incorrect diagnoses (e.g., myoclonic epilepsy) before the correct diagnosis by an expert specialist [12,13], and even in the 21st Century, patients are not given a diagnosis because of incorrect perceptions as to the "core" features of GTS. Secondly, there are possible problems brought about by GTS comorbidities such as attention deficit hyperactivity disorder (ADHD), obsessive-compulsive behaviors (OCB) and disorder (OCD), oppositional defiant disorder (ODD), conduct disorder (CD), autistic spectrum disorder (ASD), learning difficulties, and self-injurious behaviors (SIB) [3,7], which may "mask" tics, as the difficulties which other disorders pose may be much more of a problem to the individual and family.…”

“…The study shows that percentage of the patients with TS delayed to be diagnosed is 78.6% (with a lag time from 1 to 8 years) and the leaking diagnosis rate 42.9% (18/42), and the misdiagnosing rate 23.8% (10/42), all of which are compatible with the previous report [12]. Such relatively high misdiagnosis indicates that the medical workers in Wenzhou did not have complete understanding of this disease or the parents who did not recognize their children's abnormal behavior and illness.…”

An epidemiological survey on Tourette syndrome (TS) in a developing country is relatively scarce. This study was conducted to investigate the prevalence and distribution of TS in children and juveniles aged 7-16 years in Wenzhou of P.R. China. A total of 9742 children and adolescents were included in this survey. Cross-sectional study with stratified-cluster sampling method was used. The prevalence of TS among school-age children was estimated to be an average of 0.43%. The ratio of male to female was 10.6 to 1 (0.74% for males and 0.07% for females). Pupils in the age range of 7-16 years are more likely to have comorbid disorders. The mean age at onset of TS was 7.7+/-2.7 years, with 45.2% of them at the age of 6-7. The rate of delayed diagnosis, misdiagnosis and misclassification of the syndrome were 78.6, 42.9 and 23.8%, respectively. This survey supports that TS is a common disease prevalent amongst children and juveniles in Wenzhou area of P.R. China, and its incidence was correlated with age and sex and often misdiagnosed and misclassified.
