Filter by:The primary purpose of this study is to investigate the effect of deep brain stimulation (DBS) in patients with Treatment-refractory Tourette's syndrome (TR-TS) implantation targeting the Antero-medial globus pallidus interna (GPi), Antero-medial globus pallidus interna (amGPi), Postero-ventrolateral GPi (pvGPi), Centromedian nucleus, substantia periventricularis and nucleus ventro-oralis internus (Cm-Spv-Voi), Centre median nucleus and nucleus ventro-oralis (Cm-Voi), or Nucleus Accumbens/ Anterior Limb of Internal Capsule (NA-ALIC), or other unreported nuclei targets.
This study is designed to evaluate the efficacy and safety of gemlapodect (NOE-105) on reducing tics associated with Tourette Syndrome (TS) in adults with TS. Adolescents will be enrolled after a sentinel cohort of adults is complete.
The goal of this study is to evaluate the proportion of assertiveness difficulties in Tourette syndrome. Participants will complete several e-questionnaires (on assertiveness, Tourette severity, quality of life, self-esteem and comorbidities like depression, anxiety...).
There are currently no approved medications for the treatment of anxiety in children and youth with neurodevelopmental disorders (NDDs), both common and rare. Sertraline, a selective serotonin reuptake inhibitor, has extensive evidence to support its use in children's and youth with anxiety but not within NDDs. More research is needed to confirm whether or not sertraline could help improve anxiety in children and youth with common and rare neurodevelopmental conditions. This is a pilot study, in which we plan to estimate the effect size of reduction in anxiety of sertraline vs. placebo. across rare and common neurodevelopmental disorders, and determine the best measure(s) to be used as a primary transdiagnostic outcome measure of anxiety, as well as diagnosis specific measures in future, larger-scale clinical trials of anxiety in NDDs.
Tourette disorder (TD) is a neurodevelopmental disorder characterized by motor and vocal tics. It is often associated with multiple psychiatric comorbidities involving a high degree of impulsivity such as obsessive-compulsive disorders (OCD), attention-deficit hyperactivity disorders (ADHD), and intermittent explosive disorders (IED). Although a substantial body of clinical studies have emphasized the role of the dopamine system in motor symptoms, little is known about how the serotonergic (5-HT) system modulate both cognitive and affective abilities in TD. Several lines of evidence suggest that different 5-HT receptor subtypes may constitute a crucial factor in the development and maintenance of different symptoms. Because abnormal 5-HT2A receptor bindings have been reported in patients with TD and aripiprazole (drug of first choice) is a 5-HT2A antagonist, we hypothesize that 5-HT2A receptors may play an important role in regulating psychiatric symptoms in TD such as those characterized by impulsive behaviors. To investigate the involvement of 5-HT2A receptors in TD, we propose to perform a multimodal imaging study with 20 adult patients (ON and OFF treatment). Neuroimaging data will be collected with a hybrid system that simultaneously combines the positron emission tomography (PET) and the functional magnetic resonance imaging (fMRI). A highly selective PET radiotracer ([18F]-altanserin) will map 5-HT2A receptor bindings in the whole brain, while fMRI will provide detail information regarding the altered brain activities.
Tourette syndrome (TS) is a disabling neurodevelopmental disorder characterized by motor and phonic tics. The studies proposed in this application will explore the endocrine mechanisms underlying two of the least well-understood biological characteristics of TS, namely its marked male predominance and stress susceptibility. In particular, our exploratory studies will characterize the steroid profile in TS-affected boys and girls to identify novel potential biomarkers and therapeutic targets for this disorder.
A 12-week clinical study to evaluate the safety and efficacy of T92 in pediatric patients with Tourette Syndrome.
A 28-week single-arm trial to evaluate the efficacy, safety and tolerability of TSupport (a Traditional Chinese Medicine) for adults with Tourette Syndrome.
To evaluate the efficacy, safety and tolerability of the cannabinoid-based medication SCI-110 compared to placebo in subjects with Tourette syndrome.
In children with neurodevelopmental disorders, adolescence is usually associated with a reshaping of the clinical picture and symptomatology. Tourette syndrome (TS) is a paradigmal neurodevelopmental syndrome characterised by involuntary paroxysmal movements (motor tics) and vocalisation (vocal tics) often associated with various psychiatric disorders. The neuronal and cognitive mechanisms associated with TS symptoms improvement during adolescence, or the persistence in adulthood remains unknown, and this is what we aim to address in this study.
