1 INTRODUCTION Functional tics, also known as functional tic-like behaviors (FTLBs), are a subcategory of functional neurological disorders (FNDs, also called conversion disorders in the DSM-5-TR (American Psychiatric Association, 2022)) and were previously considered relatively rare (Baizabal-Carvallo & Jankovic, 2014; Demartini et al., 2015; Pringsheim et al., 2023). FNDs are believed to arise from altered brain networks rather than abnormality in brain structures.
