Clinical Intervention in Alcohol Use Disorder

tDCS will be performed with Neuroelectrics Starstim Enobio 20, a non-invasive investigational device that has been labeled as a non-significant risk device by the FDA. This study is regulated by the FDA as an Abbreviated IDE. It has built-in safety mechanisms which allow for immediate cessation of stimulation if the subject becomes uncomfortable. The current will be administered via two electrode sponges for 25 mins with 1-2 milliamperes. These administration protocols are in line with protocols that have outlined safe administration (Nitsche 2007; 2008). No side-effects have been reported with the exception of slight itching under the electrode and occasional occurrence of headache, fatigue, or nausea (Poreisz 2007). Electrodes placement: dorsolateral prefrontal cortex (DLPFC); cathode on left DLPFC, anode on right DLPFC.
