Current pathogenetic aspects of hepatic encephalopathy and noncirrhotic hyperammonemic encephalopathy

摘要

Hepatic encephalopathy is a medical phenomenon that is described as a neuropsychiatric manifestation of chronic or acute liver disease that is characterized by psychomotor,intellectual and cognitive abnormalities with emotional/affective and behavioral disturbances.This article focuses on the underlying mechanisms of the condition and the differences between hepatic encephalopathy and noncirrhotic hyperammonemic encephalopathy.Hepatic encephalopathy is a serious condition that can cause neurological death with brain edema and intracranial hypertension.It is assumed that approximately 60%-80% of patients with liver cirrhosis develop hepatic encephalopathy This review explores the complex mechanisms that lead to hepatic encephalopathy.However,noncirrhotic hyperammonemic encephalopathy is not associated with hepatic diseases and has a completely different etiology.Noncirrhotic hyperammonemic encephalopathy is a severe occurrence that is connected with multiple pathogeneses.
