NCT03842137

Brief Summary

In the current proposal, the investigators will measure behavioral and brain responses following transcranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex (DLPFC) (anode on right DLPFC, cathode on the left DLPFC) delivered during cognitive control network (CCN) priming. Participants with opioid dependence, in the first month of prescribed buprenorphine or methadone, will be assessed twice using electroencephalographic (EEG), once prior to tDCS+CCN priming and again at the completion of 5 sessions of tDCS+CCN priming (one week later). EEG will provide validation of expected changes in these networks following tDCS stimulation of the DLPFC.

Outcome Measures

Primary Outcomes (1)

  • Opioid Craving

    Penn Alcohol Craving (Modified for Opioids). This is a 5-item measure, with each item scored 0 to 6. Items are summed for a total score from 0 to 30. Higher scores = more craving.

    2 week

Secondary Outcomes (1)

  • EEG Theta Brainwave Activity

    2 weeks

Study Arms (2)

tDCS

ACTIVE COMPARATOR

Each participant will undergo 5 consecutive (i.e., business days) sessions of active tDCS delivered to the DLPFC. During each session, participants are engaging in tasks that activate the cognitive control network.

Device: tDCS

sham tDCS

SHAM COMPARATOR

Each participant will undergo 5 consecutive (i.e., business days) sessions of sham tDCS delivered to the DLPFC. During each session, participants are engaging in tasks that activate the cognitive control network.
