Estimating the number of people with Tourette syndrome and persistent tic disorder in the United States

Estimates of the number of people in the U.S. with Tourette syndrome or other persistent tic disorders can inform service provision planning. Based on available prevalence estimates applied to 2020 population data from the U.S. Census, we estimated that 350,000-450,000 U.S. children and adults have Tourette syndrome and about one million have other persistent tic disorders. Variation across studies makes estimating the total number of people in the United States affected by these disorders challenging. More precise measurement could ensure that prevalence estimates accurately reflect all who are impacted by these disorders and who could benefit from evidence-based services.

Automated summary

Estimates suggest that there are 350,000 to 450,000 children and adults with Tourette syndrome, and approximately one million individuals with other persistent tic disorders in the United States. Variation across studies makes it challenging to accurately determine the total number of people affected by these disorders.
