We have established a multisite, international database of 3500 individuals diagnosed with Tourette syndrome (TS). The male:female ratio is 4.3:1 for the total sample, with wide variation among sites; the male excess occurs at every site. Anger control problems, sleep difficulties, coprolalia, and self‐injurious behavior only reach impressive levels in individuals with comorbidity. Anger control problems are strongly correlated with comorbidity, regardless of site, region, or whether assessed…

Progress in Genetic Studies of Tourette’s Syndrome
The main purpose for this review will be to summarize the new genetic discoveries of TS based on novel genetic methods and strategies, such as genome-wide association studies (GWASs), whole exome sequencing (WES) and whole genome sequencing(WGS) and compared with other major psychiatric disorders to understand the current status of TS genetics and its relationship with other psychiatric disorders.
The Need for a Proper Definition of a “Treatment Refractoriness” in Tourette Syndrome
