The progress on diagnosis and treatment of functional tics

Abstract

Functional tics is one type of functional movement disorders (FMD) with overlapping clinical manifestations of primary tics. It is difficult to distinguish them in clinical practice. In this text, we will introduce the epidemiology, risk factors, clinical features, diagnosis and treatment of functional tics by comparing with primary tics (especially Tourette's syndrome), with the aim to improve the rate of accurate diagnosis, and avoid misdiagnosis and mistreatment.
