Trial Summary

What is the purpose of this trial?

This trial uses a non-invasive magnetic pulse therapy to help Tourette Syndrome patients by improving their brain's ability to control movements and reduce tics. This therapy has shown promising results in reducing tic severity in Tourette Syndrome.

Do I need to stop my current medications for the trial?

The trial protocol does not specify if you need to stop your current medications. However, you must not have changed your psychotropic medications or increased their dosage in the last 14 days before starting the TMS treatment.

What data supports the idea that Theta Burst Stimulation for Tourette Syndrome is an effective treatment?

The available research shows that Theta Burst Stimulation (TBS) has been used to treat conditions like tinnitus, which is a persistent ringing in the ears, often linked with depression. In one case, a woman's tinnitus intensity decreased significantly after TBS treatment, and her depression symptoms also improved. However, the research does not provide specific data on TBS for Tourette Syndrome. Therefore, while TBS shows promise for other conditions, more research is needed to confirm its effectiveness for Tourette Syndrome. ^{1 2 3 4 5}

What safety data exists for Theta Burst Stimulation in treating Tourette Syndrome?

The provided research does not contain specific safety data for Theta Burst Stimulation (iTBS) in treating Tourette Syndrome. The studies focus on other treatments like Deep Brain Stimulation (DBS) and medications such as valbenazine and aripiprazole. To find safety data for iTBS, further research specifically targeting this treatment would be necessary. ^{6 7 8 9 10}

Is iTBS a promising treatment for Tourette Syndrome?

iTBS, or Intermittent Theta Burst Stimulation, is a promising treatment because it has shown positive effects in improving motor functions and mood in other conditions like Parkinson's disease, multiple sclerosis, and depression. It is a newer form of therapy that can be delivered quickly and has been effective in helping patients with treatment-resistant depression. ^{11 12 13 14 15}

Treatment Details

Interventions

• iTBS (Non-invasive Brain Stimulation)

Trial Overview The trial tests a non-invasive brain stimulation technique called intermittent theta-burst repetitive TMS (iTBS). It's designed to improve motor control by targeting a specific part of the brain involved in movement regulation. The study compares real iTBS treatment to a sham (fake) procedure to see if it can reduce tics in TS patients.

Participant Groups

Group I: iTBS Experimental Treatment 1 Intervention

Each participant will have two separate study days in the TMS lab. On one day, the participant will receive active pre-SMA iTBS. On the other day, the patricipant will receive sham pre-SMA iTBS. The order that active versus sham is given will be randomized and the participant will be blinded. After each iTBS session, blinding assessment will be performed. To avoid contamination of results, a minimum of 5 days between study days will be required.

Group II: Sham iTBS Placebo Group 1 Intervention

Each participant will have two separate study days in the TMS lab. On one day, the participant will receive active pre-SMA iTBS. On the other day, the patricipant will receive sham pre-SMA iTBS. The order that active versus sham is given will be randomized and the participant will be blinded. After each iTBS session, blinding assessment will be performed. To avoid contamination of results, a minimum of 5 days between study days will be required.

Findings from Research

Transcranial magnetic theta burst stimulation (TBS) effectively reduced tinnitus intensity in a 54-year-old woman, with scores decreasing from 84 to 59 points after three cycles of treatment.

TBS also significantly alleviated symptoms of severe depression, as indicated by a drop in the Hamilton Rating Scale for Depression score from 44 to 23 points, demonstrating its potential as a practical and well-tolerated intervention for patients with tinnitus and depression.

In a study involving 40 patients with chronic tinnitus, both the active treatment group and the placebo control group showed significant improvements in tinnitus functional index (TFI) scores after treatment, indicating a strong placebo effect.

However, there was no significant difference in TFI score improvements between the active treatment and sham groups, suggesting that theta burst repetitive transcranial magnetic stimulation may not be an effective therapeutic option for chronic tinnitus.

The study involved 15 patients with tinnitus who underwent multiple daily rounds of continuous theta burst stimulation (cTBS) over five days, and the treatment was completed without any adverse events, indicating safety.

Despite the safety of the treatment, the study did not find significant therapeutic effects on tinnitus symptoms, suggesting that more research with a larger sample size is necessary to evaluate the effectiveness of cTBS.

In a study involving 20 patients with chronic tinnitus, theta-burst stimulation (TBS) applied to the inferior temporal cortex was found to be safe, but did not show significant overall effectiveness in reducing tinnitus perception compared to different TBS types.

While some patients experienced slight improvements, only continuous TBS (cTBS) resulted in a significant short-term reduction in symptoms, indicating that TBS may not be a promising treatment option for tinnitus based on this study's findings.

The 'activate & fire' treatment combining acoustic stimulation with continuous theta burst stimulation (cTBS) was well tolerated by most tinnitus patients, suggesting it could be a promising approach for treatment.

However, the study did not find statistical superiority of this new method over traditional low-frequency rTMS in alleviating tinnitus symptoms, indicating that further research with larger sample sizes is needed to confirm its efficacy.

Deep brain stimulation (DBS) has shown promising efficacy in improving tics and some comorbidities in treatment-resistant patients with Tourette syndrome, based on 34 studies involving over 90 patients.

The safety profile of DBS indicates that serious adverse events are rare and typically do not lead to significant impairment, but more randomized controlled trials are needed to draw definitive conclusions about its effectiveness.

Deep brain stimulation (DBS) significantly reduces Tourette syndrome (TS) symptoms more effectively than pharmacotherapy or psychotherapy, with a reduction of 49.9% in YGTSS scores compared to 22.5% and 20.0% for medications and therapy, respectively.

DBS has a low complication rate of 0.15 adverse effects per case, indicating it is a safe option for adults with refractory TS compared to higher rates associated with pharmacotherapy (1.13/case) and psychotherapy (0.60/case).

Thalamic deep brain stimulation (DBS) showed significant long-term tic reduction in some patients with Tourette syndrome, with one patient experiencing an 88.9% improvement over 78 months, indicating potential for sustained efficacy.

However, the long-term follow-up revealed increasing side effects, such as reduced energy and visual disturbances, leading some patients to switch off the stimulator or require additional surgeries to change the stimulation target.

Valbenazine, a VMAT2 inhibitor, showed a trend towards reducing tics in Tourette syndrome patients compared to placebo, but this difference was not statistically significant across six trials involving both adult and pediatric subjects.

The medication was generally well-tolerated, with side effects consistent with its use in treating tardive dyskinesia, but due to not meeting the primary efficacy endpoint, further development of valbenazine for Tourette syndrome is unlikely.

Intermittent theta-burst stimulation (iTBS) is safe for patients with mild to moderate Parkinson's disease, showing no significant increase in cortical excitability or adverse effects during the treatment.

While iTBS improved mood in patients, it did not lead to any significant improvements in motor symptoms such as gait or bradykinesia, based on a study of 26 participants over 2 weeks.

In a study involving 36 multiple sclerosis patients, intermittent theta burst stimulation (iTBS) significantly improved manual dexterity, as shown by faster completion times in the nine-hole peg test and increased performance in the Box and Block Test.

However, iTBS did not have a significant impact on hand motor imagery abilities, indicating that while it can enhance physical tasks, it may not affect cognitive aspects of motor function.

Intermittent theta-burst stimulation (iTBS) significantly improves hand function in stroke patients, particularly in those with higher baseline motor function and the presence of motor-evoked potentials (MEPs).

The study of 72 stroke patients showed that those with MEPs and better grip strength (Group A) had the greatest improvement in motor function, suggesting that iTBS effectiveness can be predicted by these factors, allowing for more tailored neurostimulation strategies.

Intermittent theta burst stimulation (iTBS) is as effective as standard high-frequency (10 Hz) rTMS for treating treatment-resistant depression, showing non-inferiority in improving depression scores over 4-6 weeks in a study with 414 participants.

Both iTBS and 10 Hz rTMS had similar safety profiles and dropout rates, with headaches being the most common side effect, indicating that iTBS can be a viable alternative that allows for more patients to be treated in a shorter time without losing effectiveness.
