Brief summary
Minimal hepatic encephalopathy (MHE) is a covert form of hepatic encephalopathy associated with cognitive and psychomotor impairment in patients with compensated liver cirrhosis. Early detection of MHE is crucial to prevent progression to overt encephalopathy. The Psychometric Hepatic Encephalopathy Score (PHES) is a validated neuropsychological test battery for diagnosing MHE. This study aims to screen for MHE among compensated cirrhotic patients using PHES and to compare performance with healthy matched controls.
Detailed description
This cross-sectional case-control study will include compensated cirrhotic patients aged 18-70 years attending Sohag University Hospital, as well as a control group of healthy volunteers matched for age and education. All participants will undergo clinical evaluation, laboratory investigations, abdominal ultrasound, and psychometric assessment using the PHES battery (NCT-A, NCT-B, DST, SDT, LTT). PHES performance will be compared between cases and controls. The diagnostic accuracy of PHES for detecting MHE will be evaluated using sensitivity, specificity, PPV, NPV, and AUROC. Correlation analyses will explore associations between PHES scores and liver disease severity.
Interventions
A standardized paper-and-pencil neuropsychological test battery used to detect minimal hepatic encephalopathy. It includes: 1. Number Connection Test A (NCT-A) 2. Number Connection Test B (NCT-B) 3. Digit Symbol Test (DST) 4. Serial Dotting Test (SDT) 5. Line Tracing Test (LTT) Tests are administered in a quiet environment between 8 AM and 3 PM by trained personnel. Performance is recorded as completion time, error score, or point score depending on test type.
