Active clinical trials for "Tourette Syndrome"

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.

The primary aim of the present research project is to investigate the preliminary effects of four weeks of forehead temperature-regulating therapy on insomnia in adults with Tourette's disorder and co-occurring insomnia disorder. This project will also examine the effects of the device on depression, anxiety, and daytime sleepiness, and explore its effects on tic severity.

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 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).

This study examines circadian rhythms and morningness-eveningness preference in youth with Persistent Tic Disorders (PTDs), including Tourette's Disorder (TD); and assesses the effects of wearable short wavelength light therapy on circadian rhythms and tic symptoms.

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.

Tics are the hallmark symptoms in Tourette Syndrome. Patients with Tourette Syndrome have difficulties controlling unwanted movements. The ability to control the motor system involves the pre-supplementary motor area (pre-SMA) in the brain. In this study, we will use Transcranial Magnetic Stimulation to modulate the pre-SMA and determine effect on the ability to stop an unwanted action in a behavior task (stop signal task).

The investigators will implant and monitor 8 research subjects with a subcortical closed-loop system for detection and suppression of tics. The project will use the FDA-approved "Medtronic Percept PC" device, which is an implantable neurostimulator capable of recording neural signals. The study will target the CM nucleus of the thalamus and the aGPi in each brain hemisphere from each subject and we will connect the two leads placed in each brain hemisphere to two Percept devices.

This is a single site, pilot double-blind, randomized, placebo-controlled, cross-over study of 10 participants comparing medicinal cannabis (THC:CBD 10:15 oil) with placebo in reducing tics in adolescents aged 12 - 18 years with severe Tourette Syndrome (TS). The primary objective of this pilot study is to evaluate all elements of the study design (recruitment strategy, study duration, study procedures, study medication tolerance and outcome measures) to assess if they are acceptable and feasible for the conduct of a full-scale randomized controlled trial of THC:CBD 10:15 oil to reduce tic severity in adolescents with TS. The secondary objective of this study is to collect preliminary data on the safety of oral THC:CBD 10:15 oil in adolescents aged 12 to 18 years with TS. As an exploratory aim data from clinician- and parent-rated measures will be compared across the phases to explore for a signal of efficacy on primary (tic reduction) and secondary (premonitory urges, obsessive compulsive behaviors, Attention Deficit Hyperactivity Disorder [ADHD] symptoms) outcome measures.

The purpose of this study is to evaluate the effectiveness and safety of deep brain stimulation (DBS) as a possible new treatment for Tourette Syndrome (TS). This investigation will (1) test the hypothesis that centromedian (CM) continuous brain stimulation will be an effective, safe method for the treatment of tics in medication refractory TS, (2) will define the intra-operative and post-operative physiological changes, and (3) will test the hypothesis that responsive brain stimulation (RBS) will provide an alternative to chronic DBS in TS.
