Alcohol Use Disorder Clinical Trial

Official title: Personalized Approach Bias Modification to Reduce Heavy Drinking and Improve Cognitive Control in Veterans With Mild to Moderate Traumatic Brain Injury

Status Not yet recruiting

Clinical Trial Summary

The project will examine the neural associations of alcohol approach-bias and investigate the extent to which a neuroscience-based personalized cognitive training program will remediate alcohol approach-bias and improve recovery outcomes among heavy drinking Veterans with alcohol use disorder (AUD) and a history of mild-moderate traumatic brain injury (mmTBI). Alcohol approach-bias modification (ApBM) is a cognitive training intervention designed to interrupt and modify automatic approach processes in response to alcohol cues. Modification of alcohol approach-bias and reductions in heavy alcohol use can be expected to reduce behaviors of self-harm and violence, increase adherence to medical care, reduce drinking-related medical costs, and promote healthier relationships. The long-term goal is to demonstrate the efficacy of ApBM to promote recovery from AUD in Veterans with chronic mmTBI. The investigators also aim to identify neural mechanisms associated with ApBM and other neurocognitive predictors of successful recovery. The evidence garnered from this study will be useful to inform the development of other behavioral and pharmacological treatments for Veterans with AUD with a history of mmTBI.

Clinical Trial Description

This study is the first to test if Alcohol approach-bias modification (ApBM), delivered through virtual reality, as an add-on to outpatient treatment can reduce heavy alcohol use and improve neuro-cognitive outcomes among Veterans with mild to moderate traumatic brain injury (mmTBI) engaged in outpatient treatment for alcohol use disorder (AUD). This will be a Phase II double-blind, randomized, sham-controlled clinical trial. Approximately 100 heavy drinking Veterans with alcohol use disorder (AUD) and a history of mild to moderate traumatic brain injury (mmTBI) will be randomized into the study to complete a 3-week of either personalized ApBM or sham training (9 training sessions). Immediately following the 3-week training, a post-intervention Week-4 assessment will be administered. The participants will also be re-assessed again at Week 12 as the last study visit. The aims of the study are as follows: Aim 1: Establish the efficacy of a personalized alcohol ApBM to promote recovery from AUD among heavy drinking Veterans with a history of mmTBI. Aim 2: Evaluate alcohol ApBM related change in fMRI cue-induced craving outcomes of treatment response within Default Mode Network. Aim 3: Assess alcohol approach bias modification-related improvement in cognitive executive functioning domains that typically show deficit in heavy drinking Veterans with mmTBI and replicate preliminary associations between executive function domains and alcohol approach bias. ;
