Detailed Description

As a major global public health issue, the core therapeutic goal of alcohol use disorder (AUD) is to reduce alcohol craving and prevent relapse. In recent years, transcranial ultrasound stimulation (TUS) has emerged as a reliable non-invasive neuromodulation technique. Studies have shown that abnormalities in neural activity and structure in the ventromedial prefrontal cortex (vmPFC) of AUD are closely associated with alcohol craving and dysregulation of the reward system. However, existing research on non-invasive neuromodulation techniques for AUD has primarily focused on other brain regions, with limited exploration of interventions targeting the vmPFC. This study aims to evaluate the efficacy of a TUS intervention targeting the vmPFC through a randomized controlled trial, assessing its potential to reduce alcohol craving and prevent relapse, thereby providing a theoretical foundation for clinical translation.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention group
The active group will receive active transcranial ultrasound stimulation.
Device: Active TUS-vmPFC
Participants in the active stimulation group will receive the transcranial ultrasound stimulation (TUS) targeted the left ventromededial prefrontal cortex (vmPFC), localized via the FP1 electrode position of the International 10-20 EEG system. The TUS will be delivered in the form of pulsed sinusoidal waves, with a fundamental frequency of 0.5 MHz and an intensity of 8 W/cm² (spatial peak pulse average intensity [Isppa]). The pulse duration will be 500 microseconds, and the sonication bursts will consist of 50 tone bursts per session, with a duty cycle of 5%. Each burst (pulse repetition frequency: 100 Hz) was followed by an 8-second inter-burst interval, yielding a total session duration of 15 minutes. Participants underwent one daily session for 10 consecutive days.
Sham Comparator: Control group
The sham group will receive shame transcranial ultrasound stimulation.
Device: Shame TUS-vmPFC
The sham stimulation protocol maintained identical parameter settings to the active treatment group with equivalent application of ultrasound coupling gel at the left vmPFC site localized via the FP1 electrode. Crucially, the ultrasound transducer's output trigger was disabled during sham sessions, ensuring identical device operation procedures without acoustic energy delivery. Participants received daily 15-minute sham sessions matching the active group's 10-day treatment schedule.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The change of alcohol craving
Time Frame: baseline, immediately after the intervention, two weeks after the intervention, one month after the intervention, two months after the intervention, three months after the intervention
Alcohol craving was assessed using the Visual Analog Scale (VAS; 0-10 points, higher scores indicating greater craving) during dual-condition olfactory exposure. Participants completed sequential 1.5-minute sniffing trials with alcohol cues and neutral stimuli (water), with the final craving score calculated as the alcohol-induced VAS score minus the neutral-state baseline.
baseline, immediately after the intervention, two weeks after the intervention, one month after the intervention, two months after the intervention, three months after the intervention
The change of relapse behaviors with alcohol
Time Frame: baseline, immediately after the intervention, two weeks after the intervention, one month after the intervention, two months after the intervention, three months after the intervention
Alcohol consumption and related behaviors were assessed using the Alcohol Use Disorders Identification Test (AUDIT,10 item). Each item is scored from 0 to 4 points, with higher scores indicating greater alcohol consumption.
baseline, immediately after the intervention, two weeks after the intervention, one month after the intervention, two months after the intervention, three months after the intervention
The change of drinking symptom
Time Frame: baseline, immediately after the intervention, two weeks after the intervention, one month after the intervention, two months after the intervention, three months after the intervention

baseline, immediately after the intervention
The Change of Functional Connectivity
Time Frame: baseline, immediately after the intervention
Resting-state functional magnetic resonance imaging (fMRI) will be used to evaluate changes in functional connectivity between the ventromedial prefrontal cortex (vmPFC) and the nucleus accumbens (NAC), key regions within the brain's reward network. Functional connectivity will be quantified using correlation coefficients between the vmPFC and NAC time series. Data will be aggregated to assess group-level changes in connectivity strength, with a focus on intervention-induced alterations.
baseline, immediately after the intervention
The change of EEG
Time Frame: baseline, immediately after the intervention
Electroencephalography (EEG) data were acquired using a Neuroscan SynAmps2 amplifier and a 64-channel Quick-Cap electrode system.
