Treatment Options for Covert Hepatic Encephalopathy

  • Chapter
  • First Online:

Abstract

Hepatic encephalopathy, even in its mildest form, can lead to significant deterioration in quality of life, lower overall survival, and add to caregiver burden. However, due to a paucity of symptoms, covert hepatic encephalopathy (CHE) is often ignored or neglected by physicians as well as patients. The lack of consensus among experts for both diagnosis as well as treatment of CHE adds to this problem. Treatment options for CHE include lactulose, rifaximin, ammonia scavengers, branched-chain amino acids, and probiotics. In this chapter we review the existing evidence on these agents and explain treatment decisions using a case-based approach.
