Overview

Hepatic encephalopathy is a syndrome observed in some patients with cirrhosis. It is defined as a spectrum of neuropsychiatric abnormalities in patients with liver dysfunction, when other known brain disease has been excluded.[1] Signs and symptoms may be debilitating, and they can begin mildly and gradually, or occur suddenly and severely.[2] They may include personality or mood changes, intellectual impairment, abnormal movements, a depressed level of consciousness, and other symptoms.[1][2] There are several theories regarding the exact cause, but development of the condition is probably at least partially due to the effect of substances that are toxic to nerve tissue (neurotoxic), which are typically present with liver damage and/or liver disease. Treatment depends upon the severity of mental status changes and upon the certainty of the diagnosis.[1]
