Overview

Psychometric testing may be helpful in the diagnosis of hepatic encephalopathy. The number connection test (trail making test or Reitan Test) can help. The Psychometric Hepatic Encephalopathy Score (PHES) may help including a simplified version (SPHES). The SPHES drops the trail making tests and so includes digit symbol test (DST), serial dotting test (SDT), line tracing test (LTT).

Other Diagnostic Studies

  • Psychometric testing may be helpful in the diagnosis of hepatic encephalopathy.
  • The number connection test (trail making test or Reitan Test) can help[1][2][3].
  • The Psychometric Hepatic Encephalopathy Score (PHES) may help[4][5][6] including a simplified version (SPHES)[6]. The SPHES drops the trail making tests and so includes:
    • Digit symbol test (DST)
    • Serial dotting test (SDT)
    • Line tracing test (LTT)
  • The inhibitory control test (ICT) may be a faster way to diagnose hepatic encephalopathy than standard psychometric tests (average administration time of 15 minutes versus 37 minutes).[7]
  • The Mini-Mental State Examination has been tested and may[8][9] or may not[10] help diagnose encephalopathy.
