Seventy subjects were selected and assigned into four groups:
Group I : ten healthy age matched controls.
Group II : ten patients with liver cirrhosis with evidence of OHE stage I and II .
Group III :twenty patients with liver cirrhosis with no clinical evidence of OHE but with positive psychometric evaluation.
Group IV :thirty patients with liver cirrhosis with no clinical evidence of OHE and negative psychometric evaluation.
