Addiction
About this trial
This is an interventional health services research trial for Addiction focused on measuring Brain stimulation
Eligibility Criteria
Inclusion Criteria:
- 40 treatment-seeking opioid-dependent subjects (between the ages of 21 and 65) with at least 30 days of abstinence under maintenance treatment will be included in this single blind study.
Exclusion criteria includes:
- history of seizures,
- receiving any medications known to lower seizure threshold,
- pregnancy,
- metal implants above the waist,
- brain lesions or tumors,
- a history of negative reactions to TMS, and
- a positive opioid urine screen (except methadone and suboxone

Applying active tDCS AND active TMS will reduce cue induced craving and opioid use, more than sham TMS AND sham tDCS and also either active TMS OR active tDCS alone. We will apply 10 daily sessions of brain stimulation (1 hour total treatment time). This is composed of 20 minutes active tDCS (anode on F3 EEG positioning and cathode on contra shoulder), followed by 4000 pulses of real rTMS (10Hz over left Dorsolateral Prefrontal Cortex(DLPFC) for 20 minutes at 120%MT). There will be 10 minutes rest between each module. We will test for cue-induced craving scores using VAS and urine drug screens for opioid abuse in comparison to the control group of sham TMS AND sham tDCS and the groups with only active tDCS OR active TMS.
Applying sham tDCS AND active TMS will reduce cue induced craving and opioid use, more than will sham TMS AND sham tDCS. We will apply 10 daily sessions of brain stimulation (1 hour total treatment time). This is composed of with 20 minutes sham tDCS (anode on F3 EEG positioning and cathode on contra shoulder), and 4000 pulses of real rTMS with (10Hz over left DLPFC for 20 minutes at 120%MT. There will be 10 minutes rest between each module. We will test for cue-induced craving scores using VAS and urine drug screens for opioid abuse in comparison to the control group of sham TMS AND sham tDCS.

Applying sham tDCS AND sham TMS will not reduce cue induced craving and opioid use. We will apply 10 sessions of one hour of brain stimulation.
