This PedsCases Note provides a one-page infographic on Functional Tic-like Behaviours. Functional Tic-Like Behaviors (FTLBs) are a heterogeneous spectrum of abnormal, involuntary movements or vocalizations that resemble tics but are manifestations of a functional neurologic disorder rather than a primary tic disorder such as Tourette Syndrome. It was created by Julia Dyck (Pediatric Neurology Resident, University of Alberta) and Dr. Colin Wilbur (Pediatric Neurologist, University of Alberta).
