Summary

This study tests whether combining a gentle brain stimulation technique called tDCS with computer-based cognitive training can help people with stimulant or alcohol use disorders stay abstinent. Participants, who have already been abstinent for at least three weeks, will receive cognitive training along with either active or sham tDCS. The goal is to see if this combination can improve cognition and reduce the likelihood of relapse.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
transcranial direct current stimulation (tDCS) combined with computer-based cognitive training
What this could lead to
If effective, this approach could offer a new way to reduce relapse rates and improve treatment outcomes for people with stimulant or alcohol use disorders.
What could go wrong
This is an early-stage trial with a small number of participants, so results may not be conclusive. The effects of tDCS can vary, and the sham-controlled design means some participants may not receive the active stimulation.
