Filter by:The primary objective of this study is to evaluate the long-term safety and tolerability of ecopipam tablets in children (greater than or equal to [>=] 6 and less than [<] 12 years of age), adolescents (>=12 and <18 years of age), and adults (>=18 years of age) with Tourette's Syndrome (TS).
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.
This pilot study will investigate the clinical and neurophysiological effects of repetitive transcranial magnetic stimulation (rTMS) followed by comprehensive behavioral intervention for tics (CBIT) in adult patients with Tourette's Syndrome (TS). Two groups of moderate disease severity will be randomized to receive active or sham rTMS targeted to the supplementary motor area (SMA) followed by eight CBIT sessions. The change in tic frequency and severity (primary outcome) and neurophysiological changes (secondary outcome) will be compared between the two groups. The central hypothesis is that low frequency rTMS will augment the effects of CBIT through favorable priming of the SMA network.
The goal of this qualitative study is to understand the challenges of stigmatization and discrimination in children and young adults with Chronic Tic Disorders (CTD), including Tourette Syndrome. Measuring and understanding how stigma affects those with CTD will help inform future work.
Decades of Tourette Syndrome (TS) neuroimaging research has revealed abnormal cortical and subcortical motor system network, hypothesized to result from maladaptive plasticity. Repetitive transcranial magnetic stimulation ([r]TMS) is a promising technology that utilizes the concept of neuroplasticity to modulate brain circuits. TMS modulation has the distinct advantage in terms of its non-invasive nature. Furthermore, unique stimulation paradigms such as intermittent theta-burst repetitive TMS (iTBS) allows for short stimulation time (<3 min). Using a sham-controlled protocol, the investigators propose modulating pre-SMA output using iTBS, based on our prior data of abnormal pre-SMA-mediated motor system regulation. hypothesize pre-SMA modulation results in increased pre-SMA-mediated motor inhibition. Enhancing these inhibitory measures with pre-SMA-iTBS provides the basis for improving inhibitory function in TS patients, leading to our long-term goal of neuro-stimulation to achieve clinical tic reduction.
This Phase 3 multicenter study evaluates the maintenance of efficacy, safety and tolerability of ecopipam tablets in children, adolescents and adults in the treatment of Tourette's Disorder (TD). The study includes an open-label period followed by double-blind, placebo-controlled, randomized withdrawal period.
The findings of resting-state functional magnetic resonance imaging and diffusion spectrum imaging in subtypes of tics-related disorders
The purpose of this research is to investigate the effectiveness of using an evidence-based board game scheme to improve the tics and interpersonal interactions of adolescents with Tourette syndrome.
This is a clinical trial where adolescents aged 10-16 years old with Tourette Syndrome (or chronic tic disorder) are randomized to receive either real-time functional magnetic resonance imaging (fMRI) neurofeedback targeting the supplementary motor area (for the experimental intervention) or real-time fMRI neurofeedback (NF) from a control region (for the control intervention).
Tic disorders are a class of childhood-onset neuropsychiatric disorders that occur in 1-3% of the population. Studies have shown that a non-drug treatment known as Comprehensive Behavioral Intervention for Tics (CBIT) is more effective than supportive therapy for reducing tics in children and adults. Although CBIT is now recommended as a first-line intervention for tic disorders, many patients do not have access to CBIT, in part due to a lack of trained therapists. Currently, the only option available for training therapists in CBIT is an intensive, two day, in-person behavior therapy training institute (BTTI). This study will compare the traditional in-person training approach to a recently developed online, self-paced CBIT therapist training program called CBIT-Trainer with regard to (1) therapists' ability to accurately administer CBIT and (2) change in the severity of patients' tic symptoms after being treated by a CBIT-trained therapist.
