A pattern of intact verbal abilities and impaired visuospatial abilities has led to a hypothesis of alcohol-induced right-hemisphere dysfunction in male chronic alcoholics. The applicability of this hypothesis to chronic female alcoholics was examined by administering the WAIS-R, Stark Paired Associates Tasks, and dichotic listening tasks to 15 male and 10 female alcoholics and 15 male and 10 female controls of similar age and education. Alcoholics had significantly lower Full Scale IQ scores on the WAIS-R but neither sex had a Verbal-Performance IQ difference indicative of right-hemisphere dysfunction. Male alcoholics showed deficits on both the Verbal and Visuospatial Stark Tasks, the deficit being greater on the Visuospatial Task. Male alcoholics showed an increased right-ear superiority on the verbal dichotic listening task and a decreased left-ear superiority on the musical dichotic listening task, both indicative of right-hemisphere dysfunction. The results, except for the WAIS-R, support the hypothesis that male but not female chronic alcoholics exhibit right-hemisphere dysfunction. Females, alcoholic or not, appear to be less lateralized in function.

Alcohol Use Disorder
Alcohol use disorder involves a pattern of alcohol consumption that includes compulsive use and a loss of control over intake of alcohol. The impact on physical health, socioeconomic factors, and psychiatric health is profound. Find the latest research on alcohol use disorder here.
