About this study

Official title: Integrative Examination of Neurobehavioral Mechanisms in Tic Suppression

The purpose of this study is to examine how the brain and environment interact to influence children's ability to suppress tics using a medical technology called Transcranial Magnetic Stimulation (TMS).

Read the detailed description

Objectives: This study will recruit youth with chronic tics. Chronic tics are the most common movement disorder in children. The goal of the study is to learn how the brain and environment influence children's ability to suppress tics. Specifically, we want to learn how tics are influenced by a certain part of the brain called the supplementary motor area (SMA). This part of the brain is thought to be more active in people with tics. This will be the first study to look at the relationship between SMA, tic suppression, and urges to tic.

Research Procedures: The study will take place over the course of three days within a week (about 5 hours total). The study will examine the relationship between the SMA and tic suppression using a non-invasive medical technology called Transcranial Magnetic Stimulation (TMS). Participants will have a diagnostic interview, MRI brain scan (used to find the location of the SMA), and TMS. Participants will be asked to try to suppress tics before and after TMS. The information that will be collected from participation includes information about tic symptoms, emotional and behavioral functioning, and brain activity (from MRI brain images and TMS results).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Active TMSOther

    There will be one, 30-minute TMS session. Participants randomly assigned to this group will receive 1hz "active" TMS. Tics and urges will be monitored immediately before and after TMS.

  • Sham TMSOther

    There will be one, 30-minute TMS session. Participants randomly assigned to this group will receive inactive ("sham") TMS. Tics and urges will be monitored immediately before and after TMS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Tic frequency

    Tics will be observed and counted

    Measured: Day 3

Secondary outcomes (1)
  1. Urge to tic

    The participant will be asked to give subjective ratings of premonitory urge intensity

    Measured: Day 3

Questions about this trial

What is this clinical trial studying?

An observational study of Tourette's Syndrome and Chronic Motor Tic Disorder, run by University of Minnesota at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Tic frequency (time frame: Day 3). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jul 2020.
