A total of 25 studies were examined which highlighted children and adolescents with a tic disorder commonly met the criteria for a clinical anxiety disorder. While tic severity was found to be associated with higher levels of symptoms of anxiety in both children and adolescents with Tourette Syndrome (TS) or Chronic Tic Disorder (CTD), even higher levels of anxiety have been found in individuals who had an additional co-occurring diagnosis. For example, the diagnosis of having a tic disorder with OCD was more frequently associated with internalising disorders (e.g., anxiety, depressive, and somatic symptoms), whereas a diagnosis of a tic disorder and ADHD was commonly associated with externalising disorders (e.g., impulsivity disruptive conduct, substance use, and other addictive behaviours). Further studies are needed to address gender differences in anxiety, as anxiety is likely to be more prevalent in females with a tic disorder compared to both males and those with a later age of onset of tics. This review highlights the benefits of routinely screening for anxiety in children and adolescents with tics disorders, as well as the need for further considerations on how current treatments could be modified to help with anxiety and co-occurring diagnoses.
