Researchers are making efforts to clarify the pathophysiology of TS and develop effective treatments amidst its rising global prevalence. This study aimed to retrieve publications discussing TS in the context of the dopaminergic system from 1994 to 2023, summarize previous research, and analyze the general information and hotspots to provide references for future research and clinical applications.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Literature was filtered from the Web of Science Core Collection.

The United States has consistently led in research output, and Yale University demonstrates excellence in workload, impact, and collaboration. Harvey S. Singer has the highest number of publications.
