Forty male ADS in-patients (18\u201350 years), diagnosed with ICD-10 DCR F10.24 and clinical institute withdrawal assessment for alcohol-revised (CIWA-Ar) &lt;10, were assigned to active or sham HD-tDCS (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 20 each). Participants received cathodal HD-tDCS over the insula for 10 consecutive days, with assessments conducted immediately post-intervention and at 4 weeks post-baseline to evaluate sustained effects on craving and neural activation. Brain activation was measured with Philips Ingenia CX 3T fMRI through the visual image induced craving for ethanol (VICE) task. Severity of craving and dependence was rated with the alcohol craving questionnaire (ACQ), obsessive compulsive drinking scale (OCDS), and Severity of Alcohol Dependence Questionnaire (SADQ).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Result:<\/jats:title>\n                    <jats:p>\n                      Baseline characteristics did not show any significant differences between groups.
