Using brain stimulation and cognitive training to help treat substance use disorders

Neuromodulation and Cognitive Training for Substance Use Disorders

Not applicable Interventional University of Minnesota · NCT04426214

This study is testing a new way to help people who have recently stopped using drugs or alcohol by combining brain stimulation with cognitive training to see if it can reduce the chances of relapse.

What this trial studies

This study aims to address the high relapse rates associated with substance use disorders by testing a novel intervention that combines transcranial direct current stimulation (tDCS) with cognitive training. The approach focuses on engaging specific brain biomarkers linked to relapse vulnerability to enhance cognitive function and improve treatment outcomes. Participants will be individuals who have recently abstained from substance use, and the study will monitor changes in brain activity and cognitive performance throughout the intervention.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 18 to 65 who have been abstinent from substances for at least three weeks and meet the diagnostic criteria for stimulant use disorder or alcohol use disorder.

Not a fit: Patients who have been abstinent for over nine months or have a primary substance use disorder diagnosis other than stimulant or alcohol may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce relapse rates and improve long-term recovery outcomes for individuals with substance use disorders.

How similar studies have performed: Other studies have shown promise in using neuromodulation techniques for treating substance use disorders, suggesting that this approach may be effective.
