Abstract
Hepatic encephalopathy is a reversible disorder seen in patients with advanced cirrhosis. It is manifested by wide spectrum of neurological and psychiatric abnormalities which occur due to accumulation of toxic substances specially ammonia in the brain. The common triggers include constipation GI bleeding infection, TIPS etc. it is seen in 30 to 45% of patients with cirrhosis. Presence of liver disease together with factoring out other causes of altered mental status is essential for diagnosis of HE. Management includes proper identification and treatment of underlying cause of underlying cause. Antibiotics like rifaximin, metronidazole are often given empirically to take care of infections. In addition osmotic laxatives, L-ornithine and L-aspartate (LOLA) are also used to decrease the levels of ammonia. Feacal microbiota transplant is gaining significant progress in the management of refractory hepatic encephalopathy.
