Neurostimulation for Addiction
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests new brain stimulation technologies to help people with opioid use disorders (OUDs). Researchers aim to observe how different brain areas respond to these treatments and whether they can reduce or disrupt addiction. Participants may receive various forms of brain stimulation, including traditional transcranial direct current stimulation (tDCS) and a newer method called temporal interference non-invasive deep brain stimulation (TI-NDBS). Ideal candidates are adults who smoke at least three-quarters of a pack of cigarettes daily and have a phone with internet access. As an unphased trial, this study offers participants the chance to contribute to groundbreaking research that could lead to new treatments for OUDs.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are on certain medications for ADHD, mental illness, cancer, epilepsy, migraines, or other neurological conditions.
What prior data suggests that this neurostimulation technology is safe for treating opioid use disorders?
Research shows that both treatments in this study, TI-NDBS and tDCS, are generally safe for people.
For TI-NDBS (temporal interference non-invasive deep brain stimulation), studies suggest it is well-tolerated. This method uses gentle electrical currents on the scalp to reach deep brain areas without surgery. Although it's a newer technique, no major safety issues have been reported so far.
For tDCS (transcranial direct current stimulation), extensive safety information is available. Reviews and studies indicate that tDCS does not cause lasting harm or permanent side effects. It is considered safe, even with repeated use.
Both treatments have shown minimal side effects, making them promising options for those considering participation in a clinical trial.12345Why are researchers excited about this trial?
Researchers are excited about the new neurostimulation approaches being tested for addiction because they offer innovative ways to engage the brain. Unlike traditional medications that alter brain chemistry, these treatments use electrical stimulation to directly influence brain activity. Temporal interference non-invasive deep brain stimulation (TI-NDBS) targets specific brain regions without invasive procedures, potentially offering a safer alternative with fewer side effects. Additionally, transcranial direct current stimulation (tDCS) is non-invasive and can be administered repeatedly over several days, potentially providing quick results. These approaches might open new pathways for treating addiction by altering brain circuits associated with cravings and compulsive behaviors.
What evidence suggests that this trial's treatments could be effective for opioid use disorders?
This trial will compare different neurostimulation techniques for addiction treatment. Research has shown that temporal interference non-invasive deep brain stimulation (TI-NDBS), which participants in this trial may receive, can target specific brain areas linked to addiction. Studies have found that stimulating the nucleus accumbens (NAcc) can help people stop using opioids. Non-invasive deep brain stimulation has been tested in humans and can reach deep brain areas to alter their activity.
Another method tested in this trial is transcranial direct current stimulation (tDCS). Research supports that tDCS can reduce both cravings and withdrawal symptoms in opioid addiction. Both TI-NDBS and tDCS show potential in altering brain activity related to addiction, offering hope for those struggling with opioid use disorders.13678Are You a Good Fit for This Trial?

Experimental Treatment
Active Control
Placebo Group
Participants assigned to this condition will receive active temporal interference non-invasive deep brain stimulation for 60 minutes for 5 days and will be compared to sham stimulation and tDCS.
Participants assigned to this condition will receive active temporal interference non-invasive deep brain stimulation. Participants will receive stimulation for 60 minutes on one day.
Participants assigned to this condition will receive traditional transcranial direct current stimulation for 60 minutes for 5 days.
Participants assigned to this condition will receive sham temporal interference non-invasive deep brain stimulation, in which they will have electrodes attached to the scalp but the device is only turned on for a few seconds. Participants will be in the scanner for 60 minutes for 5 days. This will be used as the control condition and compared with TI-NDBS and tDCS.
Participants assigned to this condition will receive sham temporal interference non-invasive deep brain stimulation, in which they will have electrodes attached to the scalp but the device is only turned on for a few seconds.
