Clinical Trial: Deep Brain Stimulation of the Nucleus Accumbens and the Ventral Anterior Internal Capsule for Severe Alcohol Addiction
Study Status: Recruiting
Recruit Status: Unknown status
Study Type: Interventional
Official Title: Deep Brain Stimulation of the Nucleus Accumbens and the Ventral Anterior Internal Capsule as a Novel Treatment in Severe Alcohol Addiction
Brief Summary:
The main objective of this study is to assess the efficacy of bilateral deep brain stimulation (DBS) of the nucleus accumbens (NAc) and the ventral anterior internal capsule (VC) as a novel treatment in severe alcohol addiction. The included patients have been treated so far with drugs that inhibits alcohol, or psychological behavior training.
Our hypothesis is that bilateral NAc-VC DBS will significantly reduce the craving for alcohol and thus enable the patients to decrease their alcohol intake substantially.
Detailed Summary: The nucleus accumbens (NAc) is considered associating with addiction. The ventral anterior internal capsule(VC) is proved a effective target to obsessive compulsive disorder(OCD). Like other addiction behaviors most alcohol addicts contain obsessive compulsive symptom. We explored an operation method, that is, in the Leksell stereotactic positioning system take VC as the point of entry, take NAc as the point of target, then make sure that the distance between entry and target points are included in the four contacts of electrode of DBS. When stimulator is ON the investigators can adjust parameters so that the coverage of electrode contains both Vc and NAc. The investigators suppose that bilateral NAc-VC DBS will significantly reduce the craving for alcohol and thus enable the patients to decrease their alcohol intake substantially.
