Total of 12 subjects from two centers ( Shanghai Mental Health Center and The Second Xiangya Hospital of Central South University ) who meet inclusion and don't meet exclusion criteria are recruited to undergo neurosurgical implantation of dual-target DBS in bilateral nucleus accumbens (NAcc) and anterior limb of internal capsule (ALIC) on Day 0. The DBS system will be turned on for stimulation and parameter adjustment will be conducted on day 10-14 after implantation. The efficacy and safety evaluation will be conducted in 9-32 weeks after implantation. The indicators on efficacy are heaving drinking rate, uncontrolled alcohol consumption days, maximum consecutive alcohol abstinent days. The indicators for safety are adverse events (AE) and device related AE, serious adverse events (SAE) and device related SAE, device deficiencies (DD) and device malfunction, physical examination and vital signs, laboratory examination, ECG, imageological examination, scale evaluation and early drop out ratio due to AE.
This is a multi-center, single arm, prospective, open-label, extendable study for the efficacy and safety of dual-target deep brain stimulation for treatment-resistant alcohol use disorder.
