What is the purpose of this trial?

This trial tests whether transcranial magnetic stimulation (TMS) can enhance the effectiveness of exposure therapy (ERP) for young people with Obsessive-Compulsive Disorder (OCD). Researchers aim to determine if TMS can improve brain function related to compulsive behavior and reduce compulsions during therapy. Participants will be divided into three groups to receive either one of two real TMS treatments or a sham (fake) TMS treatment before ERP sessions. Individuals with moderate to severe OCD symptoms and motor compulsions might be suitable for this trial. As an unphased trial, this study provides a unique opportunity to contribute to groundbreaking research that could improve treatment options for OCD.

Will I have to stop taking my current medications?

The trial requires that any medication you are taking must be stable, meaning you have been on the same medication and dose for at least 6 weeks with no planned changes during the study. If your medication has a high risk of causing seizures, you may need to stop taking it.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that transcranial magnetic stimulation (TMS) is safe for people with obsessive-compulsive disorder (OCD). For intermittent theta burst stimulation (iTBS), studies in similar conditions suggest it is generally well-tolerated. One study found high-dose iTBS safe for children with autism, indicating potential safety for young people.

Regarding continuous theta burst stimulation (cTBS), research suggests it can help reduce OCD symptoms. In one study, cTBS targeting a specific brain area was safe and effective in reducing OCD symptoms. Another study supports its safety, showing no significant negative effects in teenagers.

Although these treatments are still under study, research suggests they are generally safe and could help with OCD. Participants have not reported serious side effects, making these treatments promising options for those considering joining a trial. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for pediatric OCD because they combine Transcranial Magnetic Stimulation (TMS) with Exposure Therapy, potentially offering faster and more effective relief. Unlike traditional treatments like cognitive-behavioral therapy (CBT) and medications such as SSRIs, these approaches use iTBS or cTBS, targeting specific brain regions to enhance therapy outcomes. The ERP+iTBS arm targets the dorsolateral prefrontal cortex, while the ERP+cTBS arm focuses on the presupplementary motor area, both aiming to improve response to exposure therapy. This innovative combination could lead to quicker symptom reduction, offering a promising alternative to current treatment options.

What evidence suggests that this trial's treatments could be effective for OCD?

Research shows that transcranial magnetic stimulation (TMS) can help reduce symptoms of Obsessive-Compulsive Disorder (OCD). In this trial, participants in the ERP+iTBS arm will receive intermittent theta burst stimulation (iTBS), a specific type of TMS that significantly lowers OCD symptoms, with noticeable improvements within two weeks. Participants in the ERP+cTBS arm will receive continuous theta burst stimulation (cTBS), another TMS type that improves OCD symptoms, especially when focused on certain brain areas. Both iTBS and cTBS have shown promise in reducing compulsive behaviors in OCD patients, potentially making them effective treatment options when combined with exposure therapy. ^{5 6 7 8 9}

Published Research Related to This Trial

Exposure with response prevention (ERP) for youth with obsessive-compulsive disorder (OCD) has a low attrition rate of 10.24%, which is significantly lower than other treatment modalities like pharmacotherapy (17.29%) and active controls (20.63%).

The study suggests that ERP is an effective first-line treatment for OCD, as attrition is primarily due to logistical issues rather than treatment distress, indicating that concerns about distress leading to dropout are unfounded.

Metacognitive therapy (MCT) for children with obsessive-compulsive disorder (OCD) showed clinically and statistically significant improvements in symptom severity after treatment, based on a study involving 10 participants.

The benefits of MCT were maintained at both the 3-month and 2-year follow-ups, suggesting it could be a promising alternative to the traditional exposure with ritual prevention (ERP) therapy for pediatric OCD.

Exposure-based cognitive-behavioral therapy (CBT) for pediatric obsessive-compulsive disorder (OCD) does not lead to negative outcomes such as treatment attrition, poor therapeutic relationships, or low treatment satisfaction when compared to nonexposure-based treatments.

These findings support expert recommendations for using exposure-based CBT in treating pediatric OCD, helping to alleviate clinician concerns about potential adverse effects on patients and their families.

Patients with obsessive-compulsive disorder (OCD) show inhibitory deficits in motor cortex excitability compared to control volunteers, as indicated by a meta-analysis of 17 studies, suggesting a potential link to GABAergic deficits in OCD.

Repetitive transcranial magnetic stimulation (rTMS) did not significantly change resting motor threshold in OCD patients, indicating that while rTMS may influence GABAergic function, it does not affect glutamatergic synaptic transmission, which is reflected in this measure.

A systematic review of three randomized controlled trials on transcranial magnetic stimulation (TMS) for obsessive-compulsive disorder (OCD) found no significant difference in efficacy between active rTMS and sham TMS, based on standardized rating scales.

Due to insufficient data and variability in the trials, the review concluded that there is currently no strong evidence to support the use of TMS as an effective treatment for OCD.

In a study of 26 patients with obsessive-compulsive disorder (OCD), deep repetitive transcranial magnetic stimulation (dTMS) treatment resulted in a 53.9% response rate, with significant reductions in OCD severity as measured by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) after 30 treatment sessions.

The study found no significant differences in treatment response based on sex or medication status, and importantly, no adverse events were reported, suggesting that dTMS is a safe and effective option for OCD treatment in this population.

In a double-blind study involving 18 subjects with treatment-resistant OCD, repetitive transcranial magnetic stimulation (rTMS) did not show significant efficacy compared to sham treatment after 10 sessions.

After extending to 20 sessions, rTMS resulted in a significant reduction in OCD symptoms, but this effect was not maintained when accounting for depression, indicating limited effectiveness for OCD treatment.

Repetitive transcranial magnetic stimulation (rTMS) targeting the dorsolateral prefrontal cortex (DLPFC) has been shown to effectively reduce symptoms of anxiety and depression in patients with obsessive-compulsive disorder (OCD), based on a meta-analysis of 20 studies involving 688 participants.

While rTMS demonstrated a small to medium effect on reducing OCD, anxiety, and depression symptoms, the improvement in anxiety was influenced by changes in OCD severity, indicating a complex relationship between these conditions.

In a study involving 61 treatment-refractory OCD patients, all three rTMS protocols combined with exposure and response prevention (ERP) led to significant reductions in OCD symptoms, with a response rate of 57.4%.

Both high-frequency rTMS to the left dorsolateral prefrontal cortex and the left pre-supplementary motor area resulted in decreased activation in brain areas related to planning and error processing, which correlated with symptom improvement, although no significant differences in symptom reduction were found between the different rTMS groups.

Serious negative consequences (SNC) from exposure and response prevention (ERP) therapy for obsessive-compulsive disorder (OCD) are extremely rare, occurring in only 0.05% of adult clients and 0.01% of youth clients, indicating that ERP is a safe treatment option.

Despite some therapists' concerns, the study found that most therapists are willing to treat harm-related OCD, and improving communication about the safety and rationale of ERP could enhance access to this effective therapy.
