"Encephalopathy and Nitrogen Metabolism in Liver Failure" is a specialized book that offers a comprehensive collection of research reports and current overviews presented during the 11th International Symposium on Hepatic Encephalopathy and Nitrogen Metabolism in relation to liver diseases. This symposium took place from May 30 to June 1, 2002, in Amsterdam, Netherlands. The book addresses key topics such as the metabolism of ammonia and amino acids in connection with liver diseases, the assessment of hepatic encephalopathy (HE), minimal HE, experimental animal models of HE, and neuropsychiatric dysfunctions in patients with chronic liver diseases. Additionally, it covers the pathogenesis of HE, the role of astrocytes in liver diseases, acute liver failure, and cerebral edema, as well as treatment options and artificial liver support systems. This work serves as an essential resource for new research findings and ideas for professionals working in the fields of HE and nitrogen metabolism related to liver diseases.
