Brief Summary
This one-arm pilot study aims to evaluate the preliminary clinical, behavioral, and neurophysiological effects of high-intensity transcranial alternating current stimulation (HI-tACS) in individuals with alcohol use disorder (AUD). Participants will receive HI-tACS and undergo clinical and neurophysiological assessments before and after the intervention.

Outcome Measures
Primary Outcomes (1)
The change of alcohol craving
Alcohol craving will be measured by the alcohol craving Visual Analog Scale (VAS). The total score of VAS ranged from 0 to 10, in which higher scores mean a higher level of alcohol craving.
Baseline, immediately after completion of the 2-week intervention
Secondary Outcomes (9)
The change of drinking urge
Baseline, immediately after completion of the 2-week intervention
Change of the compulsive drinking behavior
Baseline, immediately after completion of the 2-week intervention
Side effects of the modulation
Immediately after each of the 20 HI-tACS sessions during the 2-week intervention period
Change of depressive symptoms.
Baseline, immediately after completion of the 2-week intervention
Change of anxiety symptoms
Baseline, immediately after completion of the 2-week intervention
- +4 more secondary outcomes
Other Outcomes (2)
Individualized Electric Field Simulation
Baseline, immediately after completion of the 2-week intervention
Change of the molecular-level neurochemistry
Baseline, immediately after completion of the 2-week intervention
Study Arms (1)
HI-tACS
EXPERIMENTALA 40-minute 15mA transcranial alternating current stimulus intervention with 77.5 Hz of real stimulus is conducted twice a day (at least 3 hours apart) for a total of 10 days in the intervention group of AUD.
