A battery of cognitive tests was administered to groups of younger (34--49) and older (50--59) alcoholics and nonalcoholic control subjects. Regardless of age, alcoholics were found to be impaired on essentially all measures of learning and memory. The relevance of these findings to the premature-aging hypothesis is discussed.
