Combining tDCS with cognitive training for people on buprenorphine for opioid use disorder

Combined tDCS and Cognitive Training as an Adjunctive Treatment in Opioid Use Disorder

NA · University of Minnesota · NCT07158853

This study will test whether adding mild brain stimulation (tDCS) combined with cognitive training helps people on buprenorphine for opioid use disorder reduce cravings and support recovery.

What this trial studies

Adults receiving buprenorphine maintenance for opioid use disorder will receive either active transcranial direct current stimulation (tDCS) paired with cognitive training or a sham stimulation paired with the same training. The intervention is delivered over multiple sessions while participants remain in their addiction treatment program. Outcomes will focus on clinical measures related to substance use, cognitive functioning, and retention in treatment. Participants with unstable psychotic disorders, certain neurological injuries, or contraindications to tDCS/MRI are excluded.

Who should consider this trial

Good fit: Adults diagnosed with opioid use disorder who are currently on buprenorphine maintenance and able to consent and comply with study procedures are eligible.

Not a fit: People with contraindications to tDCS or MRI, a history of seizures or certain neurological injuries, or active psychotic disorders are excluded and unlikely to benefit from the intervention.

Why it matters

Potential benefit: If successful, this approach could offer a non-drug adjunct to buprenorphine that helps reduce cravings and improve recovery outcomes.

How similar studies have performed: Previous small clinical and pilot studies combining neuromodulation or cognitive training in substance use disorders have shown mixed but sometimes promising results, while larger confirmatory trials remain limited.
