Brief Summary

The relapsing nature of substance use disorder is a major obstacle to successful treatment. About 70% of those entering treatment will relapse within one year. To improve treatment outcome, new interventions targeting the underlying brain biomarkers of relapse vulnerability hold significant promise in reducing this critical public health problem. This study is testing a new intervention, namely tDCS-Augmented Cognitive Training, to engage these brain biomarkers to improve cognition and improve treatment outcomes.
