Mit akar kideríteni a vizsgálat

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 treatments for alcohol use disorder (AUD) that support long-term abstinence. This study will allow the investigators to discern 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. The exploratory goal of this research is to associate genotypes and epigenetic changes with variations in intervention response and clinical outcome. Individual differences in baseline genetic profiles or epigenetic changes over the course of treatment could be associated with treatment response variability.

A vizsgálat 2 csoportja

• Participants receiving active transcranial direct current stimulation (tDCS)A vizsgált kezelés

  Participants in this group will receive 5 sessions of active transcranial direct current stimulation (tDCS) to dorsolateral prefrontal cortex (DLPFC) while in the Lodging Plus treatment program and then 5 remote sessions of active tDCS to DLPFC after discharge from the treatment program. All participants will engage in executive functioning tasks for cognitive training during tDCS intervention (active or sham) to prime the engagement of the nucleus accumbens prefrontal cortex circuit. All participants will complete 4 MRI sessions. Craving measures will be collected before the first and after the last day of tDCS sessions. Follow-up interviews will be conducted monthly during a 4-month follow-up period after intervention completion to query relapse status. The first two follow-up interviews, at approximately 1- and 2-months post-intervention, will also include collection of cognition data.
