RT info:eu-repo/semantics/article T1 Review of Prevalence Studies of Tic Disorders: Methodological Caveats A1 Cubo Delgado, Esther K1 Epidemiology K1 Prevalence studies K1 Tics K1 Movement disorders K1 Screening in epidemiology K1 Sistema nervioso-Enfermedades K1 Nervous system-Diseases K1 Medicina K1 Medicine AB Tic disorders are neurodevelopmental disorders of childhood associated with psychiatric comorbidity and academic problems. Estimating the prevalence and understanding the epidemiology of tic disorders is more complex than was once thought. Until fairly recently, tic disorders were thought to be rare, but today tics are believed to be the most common movement disorder, with 0.2–46.3% of schoolchildren experiencing tics during their lifetime. Tentative explanations for differing prevalence estimates include the multidimensional nature of tics with a varied and heterogeneous presentation, and the use of different epidemiological methods and study designs.
