Abstract:
During 2020, an increase of functional tics in children and adolescents has been observed. In this review, we present phenotypes, differential diagnosis and treatment for functional tics. We discuss potential contributing causes, like the COVID-19 pandemic and the focus on tics on social media. Functional tics are more complex than tics seen in Tourette syndrome and develop more suddenly in relation to stressors mainly in teenage girls. Psychosocial issues and comorbidities must be addressed and treated by a multidisciplinary team through psychoeducation and if necessary, cognitive-behavioural therapy.
