New Simple and Fast Digital Screening Method for Minimal Hepatic Encephalopathy in Cirrhotic Patients

Résumé fourni par la source

Covert hepatic encephalopathy (CHE) is a subtle yet significant neurological complication of liver diseases, especially in patients with cirrhosis. Although it lacks overt clinical signs, CHE severely impacts quality of life, increases accident risks, and has serious prognostic implications. It is characterized by neurocognitive symptoms detectable only through specialized neuropsychometric tests. CHE affects 30%-80% of cirrhotic patients and represents the early stage of hepatic encephalopathy, which is a predictor of mortality. Early diagnosis is essential to improve patient outcomes. The Psychometric Hepatic Encephalopathy Score (PHES) is the gold standard for diagnosing CHE, but it is time-consuming and requires specialized training. Other tests, like the Animal Naming Test (ANT), are simpler and more practical for screening minimal hepatic encephalopathy (MHE), though they lack specificity. The Stroop test shows promise as a quicker and reliable diagnostic tool, but still has limitations. Recent innovations include a smartphone-based self-screening method developed by Dobbermann et al., combining three digital tests: the Tip Test, Number Connection Test, and Modified Stroop Test. This approach correlates well with PHES, is independent of language skills, and is accessible for a diverse patient population, including those with color vision deficiencies. This tool offers a rapid and reliable way to screen for CHE even in home settings, potentially improving early detection and intervention. In conclusion, CHE is an underrecognized but critical condition that requires greater clinical attention. Current diagnostic tools have limitations, highlighting the need for more effective, practical methods. A multidisciplinary approach involving hepatologists, neurologists, and neuropsychologists is crucial to improve the diagnosis and management of CHE, ultimately enhancing patient outcomes.
