ABSTRACT
Previous studies have suggested reversibility of minimal hepatic encephalopathy in patients with liver cirrhosis after liver transplantation (LT), however, this topic is controversially discussed. We investigated this issue in a prospective study on liver cirrhotic patients listed for LT. Patients were investigated before and after liver transplantation (on average 21 months later) using a neuropsychological test battery which measured visuo-constructive and visuo-motor ability, verbal fluency, and memory function. To assess visuo-motor and visuo-constructive functions, we performed 4 tests: Rey Complex Figure Test copy, trail making tests A and B, and digital symbol test. The average percentile score of the tests, arbitrarily named the visuo-motor and visuo-constructive performance score (VMCP), was calculated. After LT, the patients did not demonstrate a significant increase of VMCP (P =.29) and additionally showed significantly lower VMCP score (P =.041) compared to control group. Analysis of individual responses showed that only 7 of 14 patients improved their VMCP values after LT. These data indicate that the cirrhosis-associated visuo-motor deficits subside or disappear only in some of the patients after LT, whereas a significant number of patients show no improvement of the visuo-motor and visuo-constructive function. We concluded that monitoring of cognitive and visuo-motor functioning is important for the post-transplant rehabilitation of patients with liver cirrhosis.
