Details and patient eligibility

About

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. In Phase I, the EEG provided validation of expected changes in these networks following tDCS stimulation of the DLPFC. In this current phase (II), the investigators will perform a larger randomized clinical trial (RCT) (active vs. sham control) to address long-term neurobehavioral outcomes, including opioid relapse, craving, and sustained EEG changes.

Full description

Investigators will perform an RCT in 100 opioid dependent participants who recently initiated buprenorphine or methadone. Participants will be randomized to receive five sessions of tDCS+CCN priming stimulation vs. sham tDCS+CCN priming. Participants will be assessed three times using electroencephalographic (EEG), once prior to tDCS+CCN priming, right after the completion of 5 sessions of tDCS+CCN priming (one week later), and again 10 weeks later.

This phase will address long-term (3- and 6-month) neurobehavioral outcomes, including opioid relapse, craving, and sustained EEG changes during a paradigm that challenges networks associated with craving (CR) and cognitive control (CCN). During the 24 weeks of buprenorphine or methadone maintenance treatment, the investigators will examine our primary clinical outcome, relapse (opioid use on >4 days per month and having an opioid positive urine screen), as well as days of opioid use.

100 participants in 2 patient groups

tDCS
Active Comparator group
Description:
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.
Treatment:
Device: tDCS
sham tDCS
Sham Comparator group
Description:
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.
Treatment:
Device: tDCS
