- W2891867670 abstract "Background Deep brain stimulation (DBS) is currently used to treat addiction, with the nucleus accumbens (NAc) as one promising target. The anterior limb of the internal capsule (ALIC) is also a potential target, as it carries fiber tracts connecting the mesocorticolimbic circuits that are crucially involved in several psychiatric disorders, including addiction. Stimulating the NAc and ALIC simultaneously may have a synergistic effect against addiction. Methods Eight patients with a long history of heroin use and multiple relapses, despite optimal conventional treatments, were enrolled. Customized electrodes were implanted through the ALIC into the NAc, and deep brain stimulation (DBS) treatment began two weeks after surgery. The patients were followed for at least 24 months. The duration of drug-free time, severity of drug cravings, psychometric evaluations, and PET studies of glucose metabolism before and after DBS were conducted. All adverse events were recorded. Results With DBS, five patients were abstinent for more than three years, two relapsed after abstaining for six months, and one was lost of follow-up at three months. The degree of cravings for drug use after DBS was reduced if the patients remained abstinent (p < 0.001). Simultaneous DBS of the NAc and ALIC also improved the quality of life, alleviated psychiatric symptoms, and increased glucose metabolism in addiction-related brain regions. Moreover, stimulation-related adverse events were few and reversible. Conclusions Simultaneous DBS of the NAc and ALIC appears to be safe, with few side effects, and may prevent long-term heroin relapse after detoxification in certain patients. (This trial was registered at ClinicalTrials.gov, NCT01274988)." @default.
