Other causes of neurocognitive impairment than covert hepatic encephalopathy (CHE) are very frequent, either alone or associated with CHE, in cirrhotic patients with cognitive complaints.

Summary: Background/Aims: Although it is well admitted that cirrhotic patients display various causes of neurocognitive impairment (NI) hampering the diagnosis of covert hepatic encephalopathy (CHE), those are almost never investigated per se. The aims of this study were, in cirrhotic patients displaying cognitive complaints explored by a complete multimodal work‐up, to assess: (1) the prevalence of CHE and/or that of other causes of NI and (2) their outcomes, according to the cause of NI. Methods: Prospective cohort of cirrhotic patients referred in a dedicated clinic because of cognitive complaints. Work‐up included a complete neuropsychological assessment, electroencephalogram (EEG) and brain magnetic resonance imaging with spectroscopy. The diagnosis of CHE was made by an adjudication committee involving the physicians/neuropsychologist. Results: One hundred and twenty‐three patients were included (alcohol/MASLD/virus in 63/53/14%, MELD = 11). Sixty‐six per cent of them were diagnosed with CHE; among them, 73% exhibited also other causes of NI, mainly cerebrovascular diseases/psychiatric. Among patients without CHE, 48% and 59% displayed pathological Psychometric Hepatic Encephalopathy Score and animal naming test, respectively. Clinical improvement was observed in 77% of the patients re‐evaluated after specific management. CHE, but not the other causes of NI, was independently associated with OHE occurrence. Conclusion: Other causes of NI than CHE are frequent in patients with cirrhosis, and not ruled‐out by the classical tests dedicated to CHE. Prognosis was influenced by the cause of NI. The management of patients even without CHE led to clinical improvement, underlining the need for a multifaceted approach of cirrhotic patients with cognitive complaints. [ABSTRACT FROM AUTHOR]
