Abstract

Hepatic encephalopathy (HE) is a metabolically induced neuropsychiatric syndrome that is not always reversible that can result in significant morbidity and mortality. The incidence is unknown, but it is estimated that most individuals with cirrhosis develop some degree of HE, and advanced age is a risk factor. Cognitive, behavioral, and motor dysfunction are the characteristic features of HE, although the pattern and severity differ among grades. Neuropsychologists are most likely to encounter HE in the context of liver transplant evaluations. The current chapter reviews the classification and pathogenesis of HE and diagnosis and treatment considerations and also provides clinical cases as examples and reviews practical issues that will arise for neuropsychologists involved in the care of patients with HE.
