Impact of Cirrhosis on the Neuropsychological Test Performance of Alcoholics

Alcoholics and nonalcoholics with biopsy-proven cirrhosis were compared to each other and to a normal control group on a comprehensive battery of neuropsychological tests. No systematic differences were found between the two liver disease groups. These results indicate that a history of alcoholism does not substantially contribute to the manifest neuropsychological deficits beyond that due to a coexistent hepatic encephalopathy.
