Abstract

Non-alcoholic fatty liver disease (NAFLD) is now characterized as the hepatic manifestation of metabolic syndrome, is the leading cause of liver cirrhosis and currently affects a quarter of the world's population. A number of recent studies have focused on the prevalence of neurodegeneration, including dementia and cognitive impairment in NAFLD. Various risk factors, including insulin resistance, cerebrovascular dysfunction, intestinal dysbiosis, hyperammonemia, neuroinflammation and etc. Given the prevalence of NAFLD, its negative impact on cognitive function is a medical problem with enormous social and economic consequences.
