AbstractIn this update we review our past publications on this topic and add new information onTourette syndrome (TS) and speech and language disorders. The phenotype for TS is comprised of vocal and motor tics. The vocal tics are expressed as simple and complex, and in nearly all cases share the same neurolinguistic mechanisms of speech and language for insertion into speech and discourse. The tics are typically inserted into ongoing speech at pauses, points of change in inflection, and are typically without meaning. Adherence to segmental, lexical, and suprasegmental rules of linguistics suggest the role of tic selection; expression and elimination of tics involves multiple linguistic mechanisms which are poorly understood. TS increases the risk for clinically signif-icant speech and language disorders. KeywordsVocal tics.Coprophenomena.Tic selection. Dysfluencies.Phonology. Pragmatics.Expressive language.
