Neurophysiologic and psychometric changes in patients with liver cirrhosis

ABSTRACT

Because of its prognostic and socioeconomic relevance, interest has focused on SHE, which describes a poorly defined syndrome found in the grey zone between normality and manifest HE. the aim was to study the neurophysiologic and nero psychologic changes in chronic liver diseases to diagnoses subclinical heptic encephalopathy [SHE]. Sixty patients with chronic liver disease 30 had cirrhosis due to chronic HCV [group 1], and 30 patients had liver fibrosis due to Schistosomiasis [alone or with hepatitis] [group2]. and 20 healthy subjects as control [group 3], all were subjected to, clinical examination, assessment of liver function, routine tab., investigations, Abd, US. and EEG and psychometric assessment by [NCT] and symbol [SDT]. NCT abnormal score was found in 46.7% group2. ranging from 42.3% to 75% in Child-Pugh grade A, B respectively, however the control group had normal NCT score. Positive EEG changes were in [60%]and [50%] ranging from [47.05% to 76.92%] and from [46.15% to 75.0%], in group 1 and group 2 in Child-Pugh grade A and B, respectively, while in group 3 EEG was normal in [90%] and non specific changes found in[10%]. EEC changes and psychometric defects were detected in considerable percentage of cirrhotic patients and were related to the severity of liver cirrhosis, so psychometric tests and EEG may be suitable tools for diagnosis of SHE
