Hepatic encephalopathy (HE) is a reversible syndrome observed in patients with liver disease. The syndrome is characterised by a spectrum of neuropsychiatric abnormalities resulting from the accumulation of neurotoxic substances in the bloodstream and ultimately in the brain. HE is a huge burden to patients, caregivers, and the healthcare system. Common treatments for HE, including rifaximin and lactulose, have been shown to reduce the risk of recurrence, frequency of hospitalisations, hospital costs, and mortality. New research and therapeutics exist, including faecal transplants and small-molecule therapies such as branched-chain amino acids. This review article provides a general overview of the current understanding of HE.
