tDCS to Decrease Opioid Relapse (UH3)

NCT06432465 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 100

Summary

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.

Conditions

Interventions

DEVICE

active tDCS

The anode will be placed over the right DLPFC (F4 on the EEG 10-20 system) and the cathode over the left DLPFC65 (F3) using 25cm2 sponges at an intensity of 2mA. Stimulation will be delivered for 20 minutes via two saline-soaked surface sponge electrodes and a battery-driven, constant current stimulator (NeuroConn DC Stimulator Plus).

DEVICE

sham tDCS

Same device and procedures as active tDCS with the exception that the device includes a study mode, in which subject-specific codes are entered to deliver active or sham stimulation, keeping the administrator blinded. Sham stimulation will use a method in which stimulation will be ramped up and back down over a 30-second period at the beginning and end of sham tDCS.
