title: Is it a medical error if we do not screen cirrhotic patients for minimal hepatic encephalopathy?
abstract: Minimal hepatic encephalopathy (MHE) refers to subtle neurocognitive and neurophysiological defects in patients with liver cirrhosis without clinical signs of hepatic encephalopathy. Using appropriate diagnostic methods the prevalence of MHE is approximately 25-30%. MHE has clinical significance as it results in a diminished daily functioning, precedes overt hepatic encephalopathy and is associated with a poor prognosis. Treatment with non-absorbable disaccharides can reverse the neurocognitive and neurophysiological defects found in MHE. The failure to diagnose MHE in apparently normal cirrhotic patients could, therefore, be considered a medical error. However, whether treatment also improves patients' quality of life and prognosis remains to be determined.
