Neuromodulation and Cognitive Training for Substance Use Disorders

Recruiting

The relapsing nature of Stimulant 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. The overarching goal of this project is to expand the traditional expertise in non-invasive neuromodulation at the University of Minnesota towards developing novel paired-neuromodulation approaches using transcranial direct current stimulation (tDCS) for new addiction treatments that support long-term abstinence. This study will allow us to investigate whether the pairing of dorsolateral prefrontal cortex (DLPFC) stimulation and cognitive training can lead to improved treatment outcomes as it pertains to executive functioning and maintenance of abstinence. This paired-neuromodulation approach can potentially be used as a therapeutic intervention to decrease relapse probability in addiction. The long term goal is to develop new addiction treatments that support long-term abstinence.
