Summary: 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...

Summary: 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).

Summary: This pilot study aims evaluate the feasibility and initial efficacy of behavior therapy augmented by d-cycloserine (DCS) compared to behavior therapy augmented by placebo. After an initial assessment to determine eligibility, youth with TD will be randomly assigned to receive four sessions of behavior therapy augmented by either DCS or placebo. D-cycloserine is an FDA-approved antibiotic medicatio...

Summary: The Investigators propose a two-year, longitudinal pilot study of TS adults (>18) to determine impact of lifetime environmental stress exposure on tic severity, psychiatric comorbidity severity, and health-related quality of life (HRQOL).

Summary: Aversive sensory phenomena such as premonitory urges play a central role in the behavioral treatment model of tics. Extinction learning and extinction recall are learning processes implicated within this model, but have not been directly evaluated in youth with Tourette syndrome (TS). This study examines extinction learning and extinction recall in youth with TS using an experimental task. This st...

Summary: The most pervasive sensory manifestation of TS is sensory over-responsivity (SOR). SOR is defined as excessive behavioral response to commonplace environmental stimuli. SOR is an integral but poorly understood facet of the TS phenotype, one intertwined with core elements of the disorder and worse QOL. This proposal seeks to clarify the mechanistic bases of SOR in TS. Adults with with TS will be re...

Summary: The findings of resting-state functional magnetic resonance imaging and diffusion spectrum imaging in subtypes of tics-related disorders

Summary: Patients with tics will be asked to complete a series of validated questionnaires (in electronic and/or paper format) regarding symptoms and conditions often associated with Tourette syndrome, including premonitory urges, sensory experiences, inattention, obsessive-compulsive tendencies, anxiety, and depression. Participants will also be asked to complete a quality of life assessment. This series ...

Summary: The purpose of this protocol is to examine treatment outcomes of youth receiving the Comprehensive Behavioral Intervention for Tics (CBIT) and better understand the predictors, moderators, mediators and/or mechanisms of change for this intervention.

Summary: Aversive sensory phenomena such as premonitory urges play a central role in the behavioral treatment model of tics. Extinction learning and extinction recall are learning processes implicated within this model, but are still understudied for individuals with Tourette syndrome (TS). This study examines extinction learning and extinction recall in adults with TS using an experimental task. This stud...

Summary: This research involves retrospective and prospective studies for clinical validation of a DystoniaNet deep learning platform for the diagnosis of isolated dystonia.

Summary: 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.
