Hepatic Encephalopathy (HE) can occur as a result of either acute liver failure or chronic liver disease. The information provided in this brochure explains HE in adults and is intended to help individuals who suffer from HE as well as their caregivers. It is important to note that children can also develop HE, but their symptoms are different compared to adults and therefore this information is not helpful for children with HE. Parents are advised to talk with a healthcare provider if they think their child may have HE.
