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.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Meet the Diagnostic and Statistical Manual of Mental Disorders diagnostic criteria for AUD\n* Abstinent from alcohol use\n* Must have the intention to remain in the Lodging Plus program until the end of the intervention portion of the study.\n\nExclusion Criteria:\n\n* Any medical condition or treatment with neurological sequelae (i.e. stroke, tumor, loss of consciousness\\>30 min, HIV)\n* A head injury resulting in a skull fracture or a loss of consciousness exceeding 30 minutes (i.e., moderate or severe TBI)\n* Any contraindications for tDCS or MRI scanning (tDCS contraindication: history of seizures; MRI contraindications; metal implants, pacemakers or any other implanted electrical device, injury with metal, braces, dental implants, non-removable body piercings, pregnancy, breathing or moving disorder)\n* Any primary psychotic disorder (e.g. schizophrenia, schizoaffective disorder); Participants with other treated and stable psychiatric disorders will be included\n* Presence of a condition that would render study measures difficult or impossible to administer or interpret\n* Primary current substance use disorder diagnosis on a substance other than alcohol except for caffeine or nicotine\n* Clinical evidence for Wernicke-Korsakoff syndrome\n* Left-handedness\n* Entrance to the treatment program under a court mandate'}, 'identificationModule': {'nctId': 'NCT05062369', 'briefTitle': 'Tdcs And cogNitive traininG cOmbined for AUD (TANGO)', 'organization': {'class': 'OTHER', 'fullName': 'University of Minnesota'}, 'officialTitle': 'Tdcs And cogNitive traininG cOmbined for AUD (TANGO)', 'orgStudyIdInfo': {'id': 'STUDY00013676'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Participants receiving active transcranial direct current stimulation (tDCS)', 'description': '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.
