Individuals with alcohol-related disorders have a lower intelligence test score both in young adulthood and in late midlife, and these disorders, moreover, seem to be associated with more age-related decline in intelligence test scores. Thus, low mean intellectual ability observed in individuals with alcohol-related disorders is probably a result of both lower premorbid intelligence and more intellectual decline.
