title: The role of cirrhosis in memory functioning of alcoholics.
abstract: The effects of alcoholism and liver disease on memory functioning in alcoholics were studied by comparing four groups: normal healthy controls, alcoholics without liver disease, alcoholics with biopsy-confirmed cirrhosis, and nonalcoholics with postnecrotic cirrhosis. Memory capacity was evaluated employing the Benton Visual Retention Test (BVRT), the Rey-Osterreith Complex Figure Test, Digit Span, and the Brown Peterson four-word short-term memory test. A 2 x 2 ANOVA revealed significant main effects for both alcohol and cirrhosis on Digits Forward and the total score on the Brown Peterson test. Additionally, there were significant main effects for cirrhosis on the BVRT. The Brown Peterson test was analyzed using a repeated measures 2 x 2 ANOVA. Significant effects for cirrhosis were observed at all three interpolation periods. The effects for alcohol approached significance at the 30-sec (most difficult) interpolation period. Analysis of error patterns on the Brown Peterson test indicated that overall omission errors were most commonly made among all groups. Significant effects were found for alcohol on omissions and intrusion, while the cirrhosis factor yielded significant effects for phonemic, perseverative, and omission errors. This study demonstrates the importance of liver disease underlying the etiology of memory impairments in alcoholics. The results confirm our earlier findings that neuropsychologic deficits seen in alcoholics may be the result of the combination of alcohol abuse and liver disease.
