Neuroeconomic Decision-Making for Alcoholism
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to understand how the brain responds to alcohol-related cues and how these responses affect drinking decisions. Participants will view images of alcoholic and non-alcoholic drinks while researchers monitor their brain activity using an fMRI (a type of brain scan). The study focuses on heavy drinkers who aren't seeking treatment and regularly consume more than average amounts of alcohol. It explores how environmental factors and personal choices influence the desire to drink. Eligible participants are those who identify as heavy drinkers but are not currently seeking help for alcohol issues. As an unphased trial, this study offers participants the opportunity to contribute to valuable research that could lead to better understanding and interventions for alcohol use.
Will I have to stop taking my current medications?
If you are currently taking psychotropic medications or medications that could affect blood flow in the brain, you would not be eligible to participate in this study.
What prior data suggests that these neuroeconomic techniques are safe for participants?
Research has shown that exposing people to alcohol-related images or scenarios, known as alcohol cue exposure, has been widely studied in relation to alcohol use disorders. One review found that this therapy can have varying effects on drinking habits, sometimes leading to small to moderate reductions in alcohol consumption. Another study discovered that using technology to assist with cue exposure significantly reduced cravings and drinking more effectively than traditional methods.
Alcohol cue exposure is a well-established approach in studying alcohol use disorder. Its long history in research supports its safety. Generally, participants handle the exposure well, with few negative effects reported. This suggests that alcohol cue exposure is safe, especially in controlled research settings.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores how different cues might influence decision-making in individuals with alcoholism. Unlike traditional treatments that focus on medication or therapy, this approach examines how exposure to alcohol-related and neutral images can affect the brain's purchasing decisions related to alcohol. The trial's unique angle lies in its use of neuroeconomics, which combines neuroscience and economic principles, to potentially uncover new ways to reduce alcohol consumption by altering decision-making processes. This could pave the way for innovative, non-invasive strategies to help people struggling with alcohol addiction.
What evidence suggests that this trial's treatments could be effective for understanding decision-making in alcoholism?
This trial will compare the effects of viewing alcohol-related images versus neutral images on participants' brain activity and decision-making. Studies have shown that pictures of alcohol can increase the desire to drink in heavy drinkers. Alcohol-related images activate brain areas associated with reward and motivation more than neutral images, such as those of water or juice. Research also shows a connection between the intensity of alcohol cravings and the severity of a person's drinking problem. Understanding these brain reactions can help explain why some people struggle to control their drinking.678910

Are You a Good Fit for This Trial?
This trial is for right-handed, English-speaking adults aged 21-55 who drink heavily (more than 14/7 drinks per week for males/females) and have at least one heavy drinking episode weekly. It's not for those seeking alcohol treatment, with other substance use disorders (except tobacco), frequent recreational drug use, certain mental health conditions, brain injuries, or MRI contraindications like metal implants.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Experimental Manipulation
Participants undergo an in-scanner alcohol cue exposure task, making decisions about alcohol consumption at various prices while brain activity is measured
Follow-up
Participants are monitored for safety and effectiveness after the experimental manipulation
What Are the Treatments Tested in This Trial?
Interventions
- Alcohol cue
- Neutral cue
Trial Overview
The study tests how the brain values alcohol when exposed to alcohol-related cues versus neutral ones using fMRI scans. Participants will make hypothetical choices about alcohol consumption at different prices while their brain activity is monitored after seeing images of alcoholic or non-alcoholic beverages.

Experimental Treatment
Participants first completed an in-scanner neutral cue exposure prior to the first two in-scanner alcohol purchase tasks runs. Participants then received an in-scanner alcohol cue exposure prior to the final two in-scanner alcohol purchase task runs. Cue exposures consisted of images of neutral (water) or alcohol (beer, wine, liquor) beverages and an imaginal script describing a drinking scenario.
