Introduction: Neurocognitive dysfunction is common in patients with liver cirrhosis who have no evidence of overt hepatic encephalopathy and is usually associated with impairment of activities of daily living in the patients. Materials and Methods: Forty patients with liver cirrhosis without overt hepatic encephalopathy were studied along with forty-one healthy controls. Blood samples were taken from the patients for liver function tests and Hepatitis B and C screening. Liver disease severity was graded using the Child-Pugh scoring system. Community Screening Interview for the Dementia (CSID) questionnaire was administered to all subjects. The CSID questionnaire assesses the cognitive functions of the subjects in the domains of language, memory, orientation, attention/calculation, and praxis. The data were collated and analyzed with the aid of SPSS 15.0 software for frequency, means, and comparison of means using Student's t-test and one-way ANOVA. Significant level was put at P< 0.05. Results: The mean age ± SD of the patients was 46.15±15.31 years and the controls was 45.66±11.54 years. There were 30 males and 10 females in the patients group while the control had has 26 males and 15 females. Majority of the patients had secondary level of education. Nine out of 40 patients (23%) had abnormally low total CSID score. The patients with liver cirrhosis performed poorly in the domains of language, memory, attention/calculation, and praxis. There was no difference in the orientation scores between the patients and the normal controls. The type of Hepatitis virus infection, serum liver enzyme, serum albumin, serum bilirubin, prothrombin time and Child Pugh class of the patients did not influence cognitive performance in the patients. Conclusion: Patients with liver cirrhosis have significant cognitive impairment compared with controls and liver function tests/ clinical parameters in the patients did not correlate with their cognitive functions.
