Background/Aims: Previous studies have suggested that hepatic (toxic-metabolic) encephalopathy, the major complication of cirrhosis, is a neuropsychiatric disorder typically seen in patients with liver dysfunction after exclusion of other known brain disease. This study aims to investigate the risk for parkinsonism during a 7-year follow-up period after a diagnosis of cirrhosis. Methods: In total, 1361 patients with cirrhosis and 6805 comparison patients without cirrhosis were included in this study. Each patient was then individually tracked for 7 years from the time of their initial diagnosis of cirrhosis to identify those who developed parkinsonism during the follow-up period. Stratified Cox proportional hazard regressions were conducted to calculate the hazard of parkinsonism for the two groups during the follow-up period, after adjusting for patient's age, monthly income, level of urbanization and geographic location. Results: Of the total 8166 sampled patients, 141 (1.7%) developed parkinsonism during the follow-up period, 48 from the study group (3.5% of the patients with cirrhosis) and 93 from the comparison group (1.4% of patients in the comparison group). Stratified Cox proportional hazard regressions show that the hazard for parkinsonism for patients with cirrhosis was 2.65 times as high (95% confidence interval=1.85-3.80, P
