 In Europe, the ESSTS published the first European clinical guidelines for Tourette syndrome and tic disorders in 2011.As of 2011, the only other guidelines in Europe were for Germany.In an editorial that accompanied the release of the guidelines, its authors said that in spite of a "high level of clinical experience, particularly in specialized centers", relative to other childhood-onset disorders, TS had been neglected in the research, possibly because TS had historically been viewed as a rare disorder, and due to the "high rate of relatively mild cases and an often favorable course with good chance of spontaneous remission".
