Filter by:The present study aims to assess the effects of non invasive electrical stimulation of the vagus nerve via transcutaneous vagus nerve stimulation (tVNS) on cognitive functions, inhibitory and tic control in patients with tic disorders. Taking into account the role that GABA plays in inhibitory control, the presence of alteration of GABA neurotransmission in Tic disorders and the possibility to increase GABA release with tVNS, the investigators hypothesized that tVNS might improve behavioral control in Tic disorders. Moreover, as suggested by previous studies investigating the effects of tVNS in other patient populations, the investigators expected that tVNS will be safe and well tolerated. Such results would encourage the use of tVNS in Tic disorders.
The purpose of this study is to develop the adult tic disorders registry in order to characterize the relationship between tic severity and tic-related impairment in women compared to men with tic disorders.
The purpose of this pilot trial is to examine the preliminary efficacy of online-delivered Comprehensive Behavioral Intervention for Tics - Enhanced (CBIT-E). In the study, 30 children with persistent tic disorders (PTDs) will be recruited via information provided to patients of the Marquette University (MU) Tic Disorders Specialty Clinic (TDSC) and information conveyed via local medical health professionals, with the goal of randomizing 10 participants to each group. For those randomized to CBIT-E, treatment will be administered according to the standard CBIT manual, but there will be two modifications. CBIT typically consists of the implementation of strategies to help manage the environment related to tics and the implementation of an exercise to engage in when an individual feels the urge to tic. CBIT-E will include these same techniques, plus additional in-session and out of session practice of the exercises, called competing responses, that individuals use when they feel the urge to tic. Treatment will be delivered over Microsoft Teams, which is a secure video conferencing system. The therapist will administer treatment from a private room in the Marquette University Tic Disorder Specialty Clinic, while the parent and child will be at their home. Treatment will include a screening visit, baseline assessment, 11 weeks (9 sessions) of CBIT-E, a post treatment assessment, and a three-month follow up assessment. Further, starting after session 3, there will be four 15-minute practice periods scheduled each week between sessions. During these practice periods, the child and therapist will meet over Microsoft Teams and the therapist will administer an enhanced reward task. Children randomized to the waitlist control (WLC) will not receive treatment during the 11-week period. Instead, they will be placed on a waitlist to receive standard CBIT following the end of the study period. Participants in this group will complete a screening visit, baseline assessment, and a final assessment, which will occur approximately 11 weeks after baseline.
Although behavior therapy is recognized as a first-line intervention for Tourette's Disorder (TD), less than 40% of adults with TD respond to this evidence-based treatment. Limited tolerance for aversive premonitory urges and affective states that accompany tics may be one likely factor that impedes behavior therapy outcomes. This study examines the relationship between distress tolerance and tic inhibition among adults with TD, and investigates the mechanism and effect of therapeutic skills training to enhance distress tolerance abilities. Findings will determine the optimal approach to enhance distress tolerance among adults with TD and ultimately lead to better behavior therapy outcomes.
Tic disorders, including Tourette's Disorder (TD) and Chronic Motor or Vocal Tic Disorder (CTD), are neurodevelopmental motor disorders characterised by motor and/or vocal tics. TD/CTD are impairing conditions with onset during childhood that often persist into adulthood. Behaviour therapy (BT) is an effective treatment for TD/CTD and is recommended as a first-line intervention in both in children and in adults. However, most adults with TD/CTD do not have access to BT due to a lack of trained professionals and geographical barriers. The objective of the study is to adapt and extend existing face-to-face BT treatment protocols for adults with TD/CTD to an internet-delivered format and evaluate its feasibility and preliminary efficacy. A total of 30 adult TD/CTD adult patients deemed eligible for the study through the recruitment process involving both psychologist and physician assessment will be enrolled in the project. The 8-modues treatment program, mainly based on exposure with response prevention with addition of other techniques will be made available for the participants in a secure treatment platform. The participants will keep in touch with a therapist using two-ways written communication in the same platform. The therapist's role will be to introduce the treatment and its modules, give feedback on the homework assignments and open the new modules as well as monitor the participants psychiatric symptoms and activity in the plattform. The measures will include tic severity secifically and disease severity in general, anxiety and depression symptoms, quality of life, treatment credibility and therapeutic alliance. The measures will be administrated at baseline, min- and post-tretment, as well at 3 and 12 months follow-up. Upon completion, this project will be the first crucial step towards the implementation of internet-delivered behaviour therapy (I-BT) for adults with TD/CTD in regular health care.
The purpose to the current study was to examine the efficacy of a telehealth, group-based, combined and intensive intervention for youth with tic disorders (TDs) and common co-occurring diagnoses. Families seeking treatment for TDs and common co-occurring diagnoses will be randomly assigned to receive treatment immediate (enrollment in the next group) or remain on a 1-month waitlist, and then receive treatment. Outcomes will be assessed across the treatment phase, immediately following treatment (post), as well as 1-month following the end of treatment.
Results from the University of Nottingham suggested that rhythmic median nerve stimulation (MNS) improves tic symptoms in Tourette syndrome (TS). The investigators will (1) provide a first replication of their study, (2) test the hypothesized electrophysiological mechanism and rule out a placebo effect as cause for the symptomatic benefit, and (3) gather information on the duration of effect after the end of stimulation and on individual characteristics that predict improvement with simulation. Completion of these Aims will give a clear go/no-go signal for a future clinical trial of chronic MNS delivered by a yet-to-be-developed wristwatch-style device. NOTE: This study is not intended to evaluate a specific device for future use. Rather it is a study to determine the action of pulsed electrical stimulation on tic symptoms and to gain early evidence of effectiveness. This is a non-significant risk device study.
Tics are unwanted, repetitive movements or sounds that are either simple or complex in appearance. Tic disorders often have a huge impact on children's life. The investigators have previously shown a positive outcome of tic training combining habit reversal training (HRT) and exposure response prevention (ERP) either as an individual therapy or in a group setting. However, young people and families are often busy, and having to use a full day as to attend to tic training often is difficult both for the young person and their families. Therefore, the present study focuses on the clinical outcome of combining virtual training with training at the hospital
Chronic tic disorder (CTD) may have a huge impact on life quality. Habit Reversal Training (HRT) and Exposure Response Prevention (ERP) are effective therapeutic modalities. This study examined the effect of a combined treatment using both HRT and ERP in children and adolescents with CTD. The treatment outcome was examined as an individual treatment compared to a group setting. There was no control group. The study examined both acute outcome and outcome at one year of follow-up. Predictive factors for treatment outcome were evaluated.
The study will examine whether combining Comprehensive Behavioral Intervention for Tics (CBIT) with inhibition of the supplementary motor area (SMA) using transcranial magnetic stimulation (TMS) normalizes activity in the SMA-connected circuits, improves tic suppression ability, and enhances CBIT outcomes in young people with tic disorder. The study will also examine different TMS dosing strategies.
