NCT02168400

Brief Summary

Long-term abstinence from alcohol is supported by a compensatory mechanism in functional brain connectivity, a potential brain biomarker that could be an intervention target. These findings provide a compelling case to explore whether this brain biomarker can be modulated to enhance patients' ability to remain abstinent. There is a need to investigate methods that can be used to increase functional brain connectivity. The overall objective of this proposal is to enhance brain functional connectivity in short-term abstinent alcoholics as a therapeutic intervention that supports abstinence.

Outcome Measures

Primary Outcomes (1)

  • Intervention Effects on Brain Functional Connectivity

    Compared mean change in brain functional connectivity (measured at two timepoints, at pre-intervention and at post-intervention) between Active tDCS and Sham groups.

    1 week

Secondary Outcomes (1)

  • Correlation Between Functional Connectivity Change and Clinical Outcome (Length of Abstinence)

    8 months

Study Arms (2)

active tDCS

EXPERIMENTAL

Subjects that are randomly assigned to this arm will receive 10 active transcranial direct current stimulation (tDCS) sessions

Device: Transcranial Direct Current Stimulation (tDCS)

sham tDCS

SHAM COMPARATOR

Subjects randomly assigned to sham-tDCS (transcranial direct current stimulation) will receive very low current stimulation at beginning and end of session, mimicking the feeling of current stimulation in the scalp, but not reaching levels that will stimulate brain function.

Device: Transcranial Direct Current Stimulation (tDCS)

Interventions

tDCS will be performed with Neuroelectrics Starstim Enobio 20, a non-invasive investigational device that has been labeled as a non-significant risk device by the FDA. This study is regulated by the FDA as an Abbreviated IDE. It has built-in safety mechanisms which allow for immediate cessation of stimulation if the subject becomes uncomfortable. The current will be administered via two electrode sponges for 25 mins with 1-2 milliamperes. These administration protocols are in line with protocols that have outlined safe administration (Nitsche 2007; 2008). No side-effects have been reported with the exception of slight itching under the electrode and occasional occurrence of headache, fatigue, or nausea (Poreisz 2007). Electrodes placement: dorsolateral prefrontal cortex (DLPFC); cathode on left DLPFC, anode on right DLPFC.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • up to 75 abstinent individuals (18-65 years old; 2 weeks of abstinence) who meet DSM-V criteria for alcohol use disorder (AUD) will be recruited from the Lodging Plus Program, part of University of Minnesota Medical Center
  • This 28-day program provides a supervised environment to treat alcoholism in which patients receive random drug/alcohol screenings daily. Lodging Plus has 50 beds and admits an average of 20 patients per week and 59% of patients admitted have a diagnosis of alcohol use disorder.
  • ability to provide written consent and comply with study procedures
  • meet the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) diagnostic criteria for AUD. Subjects may have current comorbid drug use, but their primary substance use disorder diagnosis needs to be based on alcohol use. Subjects must have the intention to remain in program until the end of the study (3 weeks). Vulnerable populations will not be included

You may not qualify if:

  • any medical condition or treatment with neurological sequelae (i.e. stroke, tumor, loss of consciousness of more than 30 min, HIV)
  • a head injury resulting in a skull fracture or loss of consciousness exceeding 30 minutes (i.e., moderate or severe TBI)
  • any contraindications for tDCS or MRI scanning (tDCS contraindications: 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.)
  • any primary psychotic disorder (e.g. schizophrenia, schizoaffective disorder). Participants with other treated and stable psychiatric disorders will be included.
  • presence of a condition that would render study measures difficult or impossible to administer or interpret
  • age outside the range of 18 to 65
  • primary current substance use disorder diagnosis on a substance other than alcohol except for caffeine or nicotine
  • clinical evidence of Wernicke-Karsakoff syndrome
  • left handedness
  • entrance to the treatment program. under court mandate
