The Effectiveness of Deep Brain Stimulation for Opioid Relapse Prevention

Phase 2
Conditions
Opiate Addiction
Interventions
Device: Suzhou Sceneray® DBS System
Registration Number
NCT02440152
Lead Sponsor
Ruijin Hospital
Brief Summary

The nucleus accumbens (NAcc) has a significant role in the process of opiate addiction and the initiation of relapse after detoxification. There is evidence that deep brain stimulation (DBS) of the NAcc exerts a positive effect on individuals with severe heroin addiction via inhibitory action .

The investigators hypothesise that bilateral stimulation of the NAcc will significantly reduce withdrawal symptoms and thus enable the patients to substantially decrease their Levomethadone usage.
