About this trial

The overall goal of this study is to investigate the added benefit of a neuromodulation intervention in individuals taking medication for treatment for Opioid Use Disorder(OUD).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Ability to provide consent and comply with study procedures

Diagnostic and Statistical Manual of Mental Disorders criteria for OUD

Undergoing medication treatment for OUD. Participants may have current comorbid drug use, but primary diagnosis must be OUD

Intention to remain in the study until intervention completion.

Disqualifiers

Any medical condition with neurological sequelae

Head injury resulting in skull fracture or loss of consciousness of >30 minutes

Any tDCS or MRI contraindication (tDCS: history of seizures, metallic cranial plates/screws or implanted device, history of eczema on scalp. MRI: unapproved metallic implants, pacemakers or any other implanted electrical device, shrapnel, metallic braces, non-removable body piercings, pregnancy, breathing or movement disorder, or claustrophobia)

Any psychotic disorder (participants with other treated and stable psychiatric disorders will be included)

Trial design

Design model

Single group

Treatments tested in this trial

  • Transcranial Direct Current Stimulation (tDCS)

    Device

    We will deliver 2-mA tDCS current intensity during a 30 minute stimulation period (including a 30-second ramp-up and 30-second ramp-down period) to the dorsolateral prefrontal cortex. Electrodes will be fixed on marked locations based on the 10-20 EEG system. Anodal stimulating electrode will be over the left DLPFC (F3) and cathodal electrode over the right DLPFC (F4).

Trial outcomes

Primary outcomes

1

tDCS effect on circuit-based target engagement of a prefrontal-incentive salience network

Compare change in correlation value (which represents the functional connectivity between pre-frontal cortex and prefrontal-incentive salience network) via paired t-test, from pre- to post-intervention

Time frame
immediately after the intervention
2

tDCS effect on executive functioning

Measure change in cognitive performance via repeated measured t-test from pre- intervention cognitive assessment to post- intervention cognitive assessment (post-intervention mean cognitive score minus pre-intervention mean cognitive score)

Time frame
immediately after the intervention

Secondary outcomes
