Deep Brain Stimulation of Nucleus Accumbens for Opioid Relapse Prevention

Deep Brain Stimulation of Nucleus Accumbens for Opioid Relapse Prevention:A Multicenter Randomized Double-Blind Sham-stimulation Controlled Clinical Trial

Nucleus accumbens plays important roles in the process of opiate addiction and initial of relapse after detoxification.According to the single-centered preliminary open-labeled prospective trial results, the investigators hypothesize that bilateral stimulation of the NAc will effectively reduce the relapse of the opiate dependence.
