What You Need to Know Before You Apply

What is the purpose of this trial?

Alcohol Use Disorders are currently positioned as the third leading cause of preventable death in the United States, constituting a humanitarian crisis with substantial financial burden on society and medical facilities. While several pharmacological interventions exist, 60% of individuals who seek these treatments relapse to alcohol within 6 months. These high relapse rates are due in part to elevated brain response to alcohol cues in the environment. This study seeks to evaluate the efficacy of one session of functional Magnetic Resonance Imaging (fMRI) guided transcranial magnetic stimulation (TMS) as a strategy to reduce brain reactivity to alcohol cues.

Will I have to stop taking my current medications?

The trial requires that your current medication regimen remains stable throughout the study. However, you must stop taking any medications that increase seizure risk at least two weeks before treatment.

Is repetitive transcranial magnetic stimulation (rTMS) safe for humans?

Research suggests that rTMS is generally safe for humans, including those with substance use disorders, although more detailed studies are needed to fully understand its safety in people with varying levels of substance use. ^{1 2 3 4 5}

How does the treatment TMS differ from other treatments for alcohol use disorder?

Transcranial Magnetic Stimulation (TMS) is unique because it is a non-invasive brain stimulation technique that targets specific brain areas to reduce alcohol cravings and use, unlike traditional treatments that often involve medication or therapy. It uses magnetic fields to stimulate nerve cells in the brain, particularly the dorsolateral prefrontal cortex, which is associated with addiction and cravings. ^{3 4 6 7 8}

What data supports the effectiveness of this treatment for alcohol use disorder?

Research suggests that repetitive transcranial magnetic stimulation (rTMS) may help reduce alcohol cravings and intake in people with alcohol use disorder. Some studies have shown that rTMS can influence brain activity related to addiction, potentially making it a promising treatment option. ^{2 3 7 8 9}

Published Research Related to This Trial

High-frequency repetitive transcranial magnetic stimulation (rTMS) targeting the right dorsolateral pre-frontal cortex significantly reduced alcohol craving in 45 patients with alcohol dependence, demonstrating its potential as an effective treatment strategy.

The study showed a moderate effect size for the anticraving effects of rTMS, suggesting that it could be combined with other medications to further reduce cravings and prevent relapse.

Efficacy of repetitive transcranial magnetic stimulation in alcohol dependence: a sham-controlled study. Mishra, BR., Nizamie, SH., Das, B., et al.[2022]

Transcranial magnetic stimulation (TMS) is emerging as a promising noninvasive treatment for substance dependence, potentially filling a gap in addiction therapies, as it is already FDA-approved for depression.

Repetitive TMS (rTMS) has shown potential in altering behavior and brain activity related to addiction, and future studies may benefit from combining rTMS with medications and cognitive behavioral therapies to enhance treatment outcomes.

In a pilot study involving 14 patients with alcohol use disorder (AUD), deep repetitive Transcranial Magnetic Stimulation (rTMS) of the dorsolateral prefrontal cortex led to a significant reduction in dopamine transporter (DAT) availability and alcohol intake after four weeks of treatment.

The results suggest that rTMS may modulate dopaminergic activity, indicating its potential efficacy as a therapeutic intervention for reducing alcohol consumption in AUD patients, although further research is needed to confirm these findings.

In a study involving 80 detoxified patients with alcohol use disorder, 10 sessions of high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) did not significantly increase the number of abstinent days over a 6-month follow-up compared to a sham treatment.

HF-rTMS also showed no impact on alcohol craving levels, indicating that this treatment may not be effective as an add-on therapy for reducing alcohol use or cravings in patients with alcohol use disorder.

Repetitive transcranial magnetic stimulation (rTMS) is emerging as a promising and safe treatment for alcohol use disorders (AUDs), potentially addressing the limited therapeutic options currently available.

rTMS may work by altering neurocircuitries related to alcohol addiction, with evidence from visual imaging studies and clinical pilot studies showing its effects on reducing alcohol craving and intake.

Repetitive Transcranial Magnetic Stimulation (rTMS) is generally safe and feasible for patients with neuropsychiatric disorders who also have a history of substance use, based on a review of 274 articles.

However, the impact of different levels of substance use on the safety and efficacy of rTMS remains unclear, indicating a need for further research in this area.

Repetitive transcranial magnetic stimulation (rTMS) has shown effectiveness in reducing cravings for tobacco, alcohol, and cocaine when applied at high frequencies to the dorsolateral prefrontal cortex (DLPFC), based on a review of eight studies.

Repeated sessions of high-frequency rTMS over the DLPFC may be particularly beneficial for decreasing smoking and alcohol consumption, suggesting that rTMS could be a promising treatment option for drug addiction.

In addition to reducing cravings, rTMS also effectively decreases substance consumption, particularly when using excitatory stimulation protocols, indicating its potential as a therapeutic intervention for substance dependence.

In a study involving 30 recently detoxified patients with alcohol use disorder, high-frequency rTMS applied over the right dorsolateral prefrontal cortex significantly reduced alcohol craving and use during the first three months after treatment compared to a sham treatment.

However, the effects of rTMS on craving and alcohol use diminished by the 12-month follow-up, indicating that while rTMS may be a beneficial short-term add-on treatment for alcohol use disorder, its long-term efficacy needs further investigation.
