Brain-Behavior Interactions in Tic Suppression

July 15, 2020 updated by: University of Minnesota

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).

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

12 years to 18 years (ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Community sample

Description

Inclusion Criteria:

  • Presence of motor and/or vocal tics for at least one year
  • English fluency

Exclusion Criteria:

  • Participants with medical conditions that are contraindicated for TMS (history of any known intracranial pathology, epilepsy or seizures, traumatic brain injury, brain tumor, stroke, implanted medical devices, current pregnancy or girls of childbearing age not using effective contraception, or any other serious medical conditions
  • Left-handedness

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Sham TMS
Participants in this group will receive one, 30 minute session of inactive ("sham") TMS.
Other: Sham TMS
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.
Active TMS
Participants in this group will receive one, 30 minute session of 1hz TMS.
Other: Active TMS
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Tic frequency
Time Frame: Day 3
Tics will be observed and counted
Day 3

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Urge to tic
Time Frame: Day 3
The participant will be asked to give subjective ratings of premonitory urge intensity

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 1, 2017

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
