Rapid onset functional tic-like behaviours in children and adolescents during COVID-19: Clinical features, assessment and biopsychosocial treatment approach.

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.
