Résumé
Pharmaco-psychiatric techniques remain the mainstay, first line treatments in substance use disorders (SUD), assisting in detoxification but largely ineffective at reducing dependence. The path to rehabilitation and freedom from addiction often proves uncertain and laborious for both patients and their significant others. Relapse rates for multiple substances of abuse are considerable and the number of SUD patients is on the increase worldwide. To assess efficacy of deep brain stimulation (DBS) as a therapeutic solution for SUDs. A systematic electronic database search of PubMed and EMBASE retrieved DBS addiction-focused studies on humans, of which a total of 26 (n = 71) from 2007 to 2023 were deemed eligible, including the first randomized controlled trial (RCT) in this field. This review was prospectively registered with PROSPERO: CRD42023411631. In addressing SUDs, DBS targeting primarily the nucleus accumbens (NAcc), with or without the anterior limb of the internal capsule, presented encouraging levels of efficacy in reducing cravings and consumption, followed by remission in some subjects, but still reporting relapses in 73.2% of patients. For treatment-refractory addictions DBS use seems limited to reducing cravings with a satisfactory degree of success, yet not clinically consistent in inducing abstinence, suggesting involvement of factors unaffected by DBS intervention. Furthermore, costs and the scale of the problem are such that DBS is unlikely to have a significant societal impact. Nevertheless, DBS may provide insight into the biology of addiction and is worthy of further research using increased methodological rigor, standardized outcome measures, and pre-established surgical protocols.

BACKGROUND
BACKGROUND
Pharmaco-psychiatric techniques remain the mainstay, first line treatments in substance use disorders (SUD), assisting in detoxification but largely ineffective at reducing dependence. The path to rehabilitation and freedom from addiction often proves uncertain and laborious for both patients and their significant others. Relapse rates for multiple substances of abuse are considerable and the number of SUD patients is on the increase worldwide.
OBJECTIVE
OBJECTIVE
To assess efficacy of deep brain stimulation (DBS) as a therapeutic solution for SUDs.
METHODS
METHODS
A systematic electronic database search of PubMed and EMBASE retrieved DBS addiction-focused studies on humans, of which a total of 26 (n = 71) from 2007 to 2023 were deemed eligible, including the first randomized controlled trial (RCT) in this field. This review was prospectively registered with PROSPERO: CRD42023411631.
RESULTS
RESULTS
In addressing SUDs, DBS targeting primarily the nucleus accumbens (NAcc), with or without the anterior limb of the internal capsule, presented encouraging levels of efficacy in reducing cravings and consumption, followed by remission in some subjects, but still reporting relapses in 73.2% of patients.
CONCLUSIONS
CONCLUSIONS
For treatment-refractory addictions DBS use seems limited to reducing cravings with a satisfactory degree of success, yet not clinically consistent in inducing abstinence, suggesting involvement of factors unaffected by DBS intervention. Furthermore, costs and the scale of the problem are such that DBS is unlikely to have a significant societal impact. Nevertheless, DBS may provide insight into the biology of addiction and is worthy of further research using increased methodological rigor, standardized outcome measures, and pre-established surgical protocols.
