31 patients with decompensated cirrhosis were detected by IQ and visual evoked potentials. The results showed that 45.2% of patients with low IQ, 41.9% of patients with abnormal visual evoked potential. 64.5% of the patients had one or two of the above abnormalities and were diagnosed as subclinical hepatic encephalopathy (SHE). Blood ammonia and plasma amino acid values may not have a clear relationship with SHE. IQ level and simple reaction time
