Brief Summary

This study proposes to examine both the peripheral and central nervous system responses when light social drinkers and binge/heavy social drinkers are exposed to oral ethanol. The findings will provide a greater understanding of the brain mechanisms (cerebral blood flow and functional connectivity) underlying the association between stress, cortisol release, heart rate variability, alcohol craving, and alcohol stimulant and sedative effects. This knowledge could be significant in developing new therapies for the treatment of alcoholism.

Detailed Description

This study was a single-blind, mixed Between Subjects and repeated measures across Alcohol and Placebo conditions in separate sessions in a 2 scan neuroimaging experiment. The two groups of participants were Moderate Social Drinkers and Binge/Heavy Social Drinkers, categorized on the basis of NIAA criteria for moderate non-binge and binge/heavy drinking. Subjects were randomly assigned to receive alcoholic or non-alcoholic beer in scanning condition 1 or condition 2. Before each scan, they were exposed to 3 12 Oz. alcoholic beer or 3 12 Oz. non-alcoholic beer via an Alcohol Taste Test (ATT) during which they were asked to taste the beers to determine if they were same or different. The order of the two conditions was counterbalanced and randomized across participants. Cerebral blood flow (CBF) was then measured using Arterial Spin Labeling. In addition to measuring the different effects of alcoholic beer vs. non-alcoholic beer on CBF, the investigators also measured subjective alcohol effects, alcohol craving, breath alcohol levels, cortisol, and ACTH. Statistical tests were performed to determine if these dependent measures were due to Group, Condition, or a Group x Condition interaction. Finally, the relationship between these variables and the amount of beer consumed at the second post-scan ATT was examined. The post-scan ATT only presented with the choice to drink non-alcoholic beer in order to more clearly predict behavioral motivation for alcohol from PreATT alcohol response in cortisol, CBF and subjective ratings. Data was obtained by research staff, nurse, and MRI technician who were blind to condition as were the subjects but PI and project director were not blind.
