Abstract

OBJECTIVES: This review examined the currently available evidence of the association between liver encephalopathy and mood/anxiety disorders.

METHOD: English-language studies using the keywords "hepatic encephalopathy," "depression," and "anxiety" were searched through PubMed, Medline, Cochrane Library, and PsycINFO databases. A total of 135 articles were considered for this review, of which 9 were qualitative and quantitative research papers regarding depression and anxiety in hepatic encephalopathy (HE).

RESULTS: There is a significant discrepancy between the research method of the studies and their outcomes. The number of studies suggesting a relationship between HE and mood/anxiety disorders is slightly higher than that of studies with opposite results; however, based on the current evidence, it is difficult to conclude a significant association between these two conditions.

CONCLUSION: More longitudinal studies that include face-to-face psychiatric assessments are required to highlight any possible association between depressive/anxiety disorders and HE.
