Background Tourette syndrome, first described in 1885, is a tic disorder differentiated from other movement disorders, such as myoclonic movements or transient tics of childhood. The median age at onset is seven years. In some cases, remissions occur or symptoms diminish. In other cases, the condition is lifelong. DSMIII-R diagnostic criteria are: multiple motor and one or more vocal tics prese...

Most patients with Tourette syndrome report characteristic sensory experiences (premonitory urges) associated with the expression of tic symptoms. Despite the central role of these experiences to the clinical phenomenology of Tourette syndrome, little is known about their underlying brain processes. In the present article we present the results of a systematic literature review of the published...

Background and Objectives: The prevalence of minor physical anomalies (prenatal errors of morphogenesis) was evaluated in patients with Tourette syndrome to get indirect data on the possible role of aberrant neurodevelopment in the aetiology of Tourette syndrome. No published study is known on the minor physical anomaly prevalence in this recently intensively investigated disorder, and connecti...

Recently, a genome-wide association study has indicated associations between single nucleotide polymorphisms in the Collagen Type XXVII Alpha 1 gene (COL27A1) and Tourette syndrome in several ethnic populations. To clarify the global relevance of the previously identified SNPs in the development of Tourette syndrome, the associations between polymorphisms in COL27A1 and Tourette syndrome were a...

Saccadic eye movements, fixation and smooth pursuit were studied in 28 children with Gilles de la Tourette syndrome and found to be normal. A link has been postulated between Gilles de la Tourette syndrome and other movement disorders. The results obtained in the present series do not support this hypothesis.

Investigators from Centre de Reference National Maladie Rare 'Syndrome Gilles de la Tourette' and Sorbonne University report white matter abnormalities in the pathways connecting the cerebral cortex, basal ganglia, and thalamus in a group of 49 adults with Tourette syndrome (TS).

BACKGROUND Tourette Syndrome (TS) is a neurodevelopmental disorder of childhood. Learning disabilities are frequently comorbid with TS. Using the largest sample of TS patients ever reported, we sought to identify differences between subjects with TS only and subjects with TS and a comorbid learning disability. METHODS We used the Tourette Syndrome International Consortium database (TIC) to co...

Promising results in adult neurologic and psychiatric disorders are driving active research into transcranial brain stimulation techniques, particularly transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), in childhood and adolescent syndromes. TMS has realistic utility as an experimental tool tested in a range of pediatric neuropathologies such as perinat...
