Neuropsychiatric performance in patients with cirrhosis: Who is “normal”?

Abstract

In patients with cirrhosis a normal neuropsychiatric performance has been traditionally defined by the absence of any degree of hepatic encephalopathy and/or the absence of psychometric or neurophysiological abnormalities, compared with data from the healthy population. As the understanding and management of end-stage liver disease continues to change, it is our impression that the concept of normal neuropsychiatric performance also needs updating. This review explores novel and more pragmatic interpretations of neuropsychiatric “normality” compared with top personal performance, in terms of risk of overt hepatic encephalopathy or brain failure and in relation with events such as liver transplantation, decompensation, acute-on-chronic liver failure and transjugular intrahepatic portosystemic shunt placement.
