The diagnosis of subclinical hepatic encephalopathy in patients with cirrhosis using neuropsychological tests and automated electroencephalogram analysis
J C Quero, I J Hartmann, J Meulstee, W C Hop, S W Schalm – 1 September 1996 – Neuropsychological tests used for the assessment of subclinical hepatic encephalopathy (SHE) may overdiagnose SHE because scores are usually not corrected for age. The aim of this study was to estimate the prevalence of SHE using two easy administrable psychometric tests (Number Connection Test part A [NCT‐A], Symbol Digit Test [SDT]) with age‐related normal values. In addition, spectral electroencephalogram (EEG) was used, which is the in‐house electrophysiological method for quantifying encephalopathy.
