TS-EUROTRAIN: A European-Wide Investigation and Training Network on the Etiology and Pathophysiology of Gilles de la Tourette Syndrome
نویسندگان
چکیده
Gilles de la Tourette Syndrome (GTS) is characterized by the presence of multiple motor and phonic tics with a fluctuating course of intensity, frequency, and severity. Up to 90% of patients with GTS present with comorbid conditions, most commonly attention-deficit/hyperactivity disorder (ADHD), and obsessive-compulsive disorder (OCD), thus providing an excellent model for the exploration of shared etiology across disorders. TS-EUROTRAIN (FP7-PEOPLE-2012-ITN, Grant Agr.No. 316978) is a Marie Curie Initial Training Network (http://ts-eurotrain.eu) that aims to elucidate the complex etiology of the onset and clinical course of GTS, investigate the neurobiological underpinnings of GTS and related disorders, translate research findings into clinical applications, and establish a pan-European infrastructure for the study of GTS. This includes the challenges of (i) assembling a large genetic database for the evaluation of the genetic architecture with high statistical power; (ii) exploring the role of gene-environment interactions including the effects of epigenetic phenomena; (iii) employing endophenotype-based approaches to understand the shared etiology between GTS, OCD, and ADHD; (iv) establishing a developmental animal model for GTS; (v) gaining new insights into the neurobiological mechanisms of GTS via cross-sectional and longitudinal neuroimaging studies; and (vi) partaking in outreach activities including the dissemination of scientific knowledge about GTS to the public. Fifteen partners from academia and industry and 12 PhD candidates pursue the project. Here, we aim to share the design of an interdisciplinary project, showcasing the potential of large-scale collaborative efforts in the field of GTS. Our ultimate aims are to elucidate the complex etiology and neurobiological underpinnings of GTS, translate research findings into clinical applications, and establish Pan-European infrastructure for the study of GTS and associated disorders.

The Genetic Etiology of Tourette Syndrome: Large-Scale Collaborative Efforts on the Precipice of Discovery
Gilles de la Tourette Syndrome (TS) is a childhood-onset neurodevelopmental disorder that is characterized by multiple motor and phonic tics. It has a complex etiology with multiple genes likely interacting with environmental factors to lead to the onset of symptoms. The genetic basis of the disorder remains elusive. However, multiple resources and large-scale projects are coming together, laun...

Gilles de la Tourette Syndrome (TS) is a neuropsychiatric disorder that is caused by a likely complex genetic basis, interacting with environmental factors. Just as multiple large scale collaborative projects for TS are starting out and the first ever genomewide association study for TS has been published, this review provides a synthetic overview of more than two decades of active research.

متن کاملEvent-related brain potentials show changed attentional mechanisms in Gilles de la Tourette Syndrome.
In many patients the Gilles de la Tourette Syndrome (TS) is associated with the childhood Attention Deficit Hyperactivity Disorder. To gain a general view of attentional processes in TS we recorded event-related brain potentials (ERPs) in 12 TS patients and in a matched control group. Four visual attention experiments with different levels of complexity were done (oddball task, pop-out experime...

Gilles de la Tourette's syndrome (TS) is a neurobehavioral disorder. Although the etiology and the pathophysiology of TS are still unknown, the involvement of the basal ganglia has long been postulated. On the other hand, saccadic eye movement was shown to be a useful measure to assess order and disorder of the function of the basal ganglia. To investigate the dysfunction of the basal ganglia o...

BACKGROUND Genome-wide association studies have not revealed any risk-conferring common genetic variants in Tourette syndrome (TS), requiring the adoption of alternative approaches to investigate the pathophysiology of this disorder. METHODS We obtained the basal ganglia transcriptome by RNA sequencing in the caudate and putamen of nine TS and nine matched normal control subjects. RESULTS W...
