Abstract
Alcohol use is often associated with impulsive choices. Alcohol dependents also exhibit deficits in executive functions as reflected by their persistent alcohol use despite of adverse consequences. The aim of this study was to clarify the decision-making functioning in alcohol-dependent patients. We compared 19 alcohol-dependent (AD) patients with 24 age-matched healthy controls on the performance of the Iowa Gambling Task (IGT). In comparison to healthy controls, the AD group made more disadvantageous choices and had a poorer performance on the IGT. These results suggest that deficits related to emotion-based learning exist in AD patients. These results may have important implications for designing treatment programs.
