Multimodal Electrophysiological Study of Cortico-subcortical Biomarkers of Tics in Tourett
Tourette syndrome (TS) is a complex neurodevelopmental disorder characterized by the occurrence of involuntary movements (motor tics) and vocalizations (phonic tics). The onset of TS is usually in childhood, and the prevalence of TS is estimated between 0.3 and 0.9% before the age of 18, decreasing progressively after

| Summary | Tourette syndrome (TS) is a complex neurodevelopmental disorder characterized by the occurrence of involuntary movements (motor tics) and vocalizations (phonic tics). The onset of TS is usually in childhood, and the prevalence of TS is estimated between 0.3 and 0.9% before the age of 18, decreasing progressively after that age. Most patients also suffer from associated psychiatric comorbidities (ADHD, OCD, mood disorders). Although the cause of TS remains unknown, the preferred hypothesis is the interaction of predisposing genetic factors and precipitating environmental factors (perinatal accidents, infectious diseases). From a pathophysiological point of view, it is widely demonstrated by structural, electrophysiological studies, functional neuroimaging, as well as by different animal mod |
