[Transcranial direct current stimulation in substance use disorders: an update]. / Transcraniële gelijkstroomstimulatie bij stoornissen in het gebruik van middelen: een update.

ABSTRACT

BACKGROUND: Existing treatments for substance use disorders are often subject to drop-out or relapse. Transcranial direct current stimulation (tDCS) possibly has a positive effect on this problem. AIM: To give an updated qualitative review of existing studies investigating the clinical effects of transcranial direct current stimulation for people with a substance use disorder, considering the many recently published studies. METHOD: Extensive literature search in the electronic database PubMed. We included 43 studies on top of the 7 studies already included in the previous review of Herremans and Baeken (2017) in this journal. RESULTS: The majority of the studies showed a positive effect of transcranial direct current stimulation on clinical measures as craving and abstinence. However, there was little uniformity in used protocols. CONCLUSION: Transcranial direct current stimulation can be an effective treatment for people with a substance use disorder. Optimal parameters need to be established to make the treatment maximally effective and adapted to the individual patient.
