What is the purpose of this trial?

This trial explores how Transcranial Magnetic Stimulation (TMS) could help people with Post-Traumatic Stress Disorder (PTSD) by easing symptoms and improving brain function. TMS is a noninvasive treatment that uses magnetic fields to stimulate specific brain areas. The trial compares real TMS sessions to sham (fake) sessions to evaluate TMS's effectiveness. It seeks participants diagnosed with PTSD, particularly those experiencing issues with arousal and reactivity. The study aims to find better ways to target brain areas for TMS and make PTSD treatments more personalized. As an unphased trial, it offers a unique opportunity to contribute to pioneering research and potentially benefit from innovative treatment approaches.

Will I have to stop taking my current medications?

You can continue taking your current medications if they are stable, meaning the type and dose haven't changed for at least 6 weeks before the study and won't change during the study.

What prior data suggests that this TMS treatment protocol is safe for PTSD patients?

Research shows that Transcranial Magnetic Stimulation (TMS) is generally safe. This noninvasive treatment uses magnetic fields to stimulate specific brain areas and has received FDA approval for treating depression unresponsive to other treatments.

Studies indicate that TMS can reduce PTSD symptoms without causing major side effects. Most people tolerate it well. Some minor side effects, like headaches or lightheadedness, might occur but usually don't last long. Research also suggests that different types of TMS, such as intermittent theta-burst stimulation, effectively treat PTSD and are well-tolerated. These findings suggest that TMS could be a promising and safe option for treating PTSD. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Transcranial Magnetic Stimulation (TMS) is unique because it offers a noninvasive approach to treating Post-Traumatic Stress Disorder (PTSD) by using magnetic fields to stimulate specific brain areas. Unlike traditional treatments for PTSD, like medication and therapy, TMS directly targets brain regions involved in mood regulation and stress response, potentially offering faster relief. Researchers are excited about TMS because it provides an alternative for those who may not respond well to conventional treatments, with the added benefits of fewer side effects and no need for medication.

What evidence suggests that Transcranial Magnetic Stimulation (TMS) might be an effective treatment for PTSD?

Research has shown that Transcranial Magnetic Stimulation (TMS), which participants in this trial may receive, can help treat PTSD symptoms. Studies have found that TMS improves PTSD symptoms as effectively as other treatments. One study noted that these improvements often occur early in the treatment. The FDA has already approved TMS for treating depression, suggesting it might also work for PTSD. Overall, TMS is considered a safe treatment that could benefit people with PTSD. ^{1 2 4 6 7}

Published Research Related to This Trial

A study involving 50 veterans with PTSD showed that intermittent theta-burst stimulation (iTBS) significantly improved social and occupational functioning after 2 weeks, indicating its potential efficacy as a treatment for PTSD.

One month after treatment, iTBS demonstrated significant reductions in both clinician- and self-rated PTSD symptoms, as well as improvements in depression and functioning, suggesting that iTBS could be a promising new approach for managing PTSD.

Bilateral sequential theta-burst stimulation (bsTBS) was well tolerated in a small study of 8 military veterans with treatment-resistant depression (TRD) and comorbid PTSD, showing promising remission rates of 25% and response rates of 38% for depression scores.

The study suggests that bsTBS may be a viable therapeutic option for patients with TRD and PTSD, indicating the need for larger studies to further evaluate its efficacy compared to other rTMS treatment paradigms.

Repetitive transcranial magnetic stimulation (rTMS) has gained popularity for its ability to modulate brain activity, but safety considerations are crucial, especially with the recent updates to safety guidelines published in 2021.

The guidelines emphasize the importance of screening for risks, monitoring for adverse events, and specific safety measures when using rTMS, particularly in patients with conditions like stroke and traumatic brain injury.

Repetitive transcranial magnetic stimulation (rTMS) is a safe treatment option for depression and shows potential for alleviating symptoms of post-traumatic stress disorder (PTSD), particularly when applied to the right dorsolateral prefrontal cortex.

High-frequency rTMS appears to be more effective than low-frequency rTMS in treating PTSD symptoms, possibly by increasing levels of brain-derived neurotrophic factor, which supports brain health and function.

In a study involving 24 PTSD patients, high-frequency repetitive transcranial magnetic stimulation (rTMS) at 10 Hz significantly improved core PTSD symptoms and alleviated anxiety over 10 daily sessions.

The results indicate that rTMS targeting the right dorsolateral prefrontal cortex is more effective than low-frequency or sham stimulation, suggesting its potential as a therapeutic intervention for PTSD.

In a safety and efficacy study involving a 26-year-old man with severe traumatic brain injury (TBI), a 6-week rTMS protocol showed no adverse events, indicating it is a safe treatment option for individuals in a minimally conscious state.

The rTMS treatment was associated with a trend toward significant neurobehavioral improvements and enhanced neural conduction, suggesting its potential to facilitate recovery in patients with severe TBI.

Theta burst stimulation (TBS) is a promising technique for altering brain excitability, with a review of studies showing that adverse events were mostly mild and occurred in only 5% of subjects, indicating a generally safe profile.

Despite its safety, TBS carries a theoretical higher risk of seizures compared to other stimulation methods, necessitating cautious application and further research into its dosing parameters to better understand seizure risks.

In a study involving 18 patients with PTSD, low-frequency repetitive transcranial magnetic stimulation (rTMS) to the right prefrontal cortex significantly improved overall PTSD symptoms, particularly in re-experiencing and total scores on the Clinician-Administered PTSD Scale (CAPS).

The results suggest that rTMS is a safe and effective treatment option for PTSD, with a notable impact on specific symptom clusters, indicating potential for further research into optimizing rTMS protocols.

Transcranial magnetic stimulation (TMS) has been found to be an effective treatment for post-traumatic stress disorder (PTSD), with a meta-analysis of three studies showing a significant reduction in PTSD symptoms.

The treatment is generally well tolerated, and right-sided TMS may be more effective than left-sided, although further research is needed to optimize treatment parameters and understand potential side effects.

In a study of 165 pediatric participants aged 6 to 18, theta-burst TMS (TBS) demonstrated a similar safety profile to single- and paired-pulse TMS (sp/ppTMS), with no severe adverse effects reported.

The overall rate of adverse effects was 10.5% for TBS and 12.4% for sp/ppTMS, with most effects rated as minimal or mild, indicating that TBS is a safe option for further investigation in children.

A study comparing intermittent theta burst stimulation (iTBS) and 5 Hz transcranial magnetic stimulation (TMS) in veterans with PTSD and major depressive disorder (MDD) found that both treatments were safe and effective, but 5 Hz TMS resulted in significantly better symptom improvement.

Veterans receiving 5 Hz TMS showed greater reductions in PTSD and MDD symptoms compared to those receiving iTBS, suggesting that while iTBS is quicker to administer, it may not be as effective for these conditions based on the current data from 20 participants.
