- Abstract
Aim: To report the prevalence and clinical characteristics of children with rapid onset functional tic‐like behaviours during the COVID‐19 pandemic. Methods: Single centre, retrospective cohort study of children (<18 years) referred to the tic clinic from January 2018 to July 2021. We calculate the prevalence of newly diagnosed functional tics, and compare the clinical features to chronic tic disorder/Tourette syndrome (CTD/TS). Results: A total of 185 new patients were referred to the tic clinic between 2018 and 2021. There was a significant increase in the percentage of functional tics in 2020 and 2021 (2% in 2018, 5.6% in 2019, 10.6% in 2020 and 36% in 2021). Differences between functional tics (n = 22) and CTD/TS (n = 163) include female predominance (100 vs. 28%, P < 0.0001), later age of onset (mean age 13.8 vs. 6.8 years, P < 0.0001) and higher rates of anxiety/depression (95 vs. 41%, P < 0.0001). The functional tic group were more likely to present with coprolalia‐like behaviours (77 vs. 10%, P < 0.0001), complex phrases (45 vs. 0.6%, P < 0.0001), copropraxia (45 vs. 2%, P < 0.0001), self‐injury (50 vs. 4%, P < 0.0001), hospitalisation/emergency visits (36 vs. 2%, P < 0.0001) and school absenteeism (56 vs. 7%, P < 0.0001). A total of 18.2% of patients with functional tics reported preceding exposure to social media content involving tics. Conclusions: There is an increase in adolescent females presenting with rapid onset functional tic‐like behaviours during the COVID‐19 pandemic. We highlight differences in clinical features between the functional tic group and CTD/TS to aid diagnosis and management in the community. Based on our findings, we propose a mixed model of neuropsychiatric vulnerability and social media contagion in this group of adolescents with functional tics.
