EEG in liver transplantation: visual and computerized analysis

Electrophysiological and neuropsychological tests for the diagnosis of subclinical hepatic encephalopathy and prediction of overt encephalopathy

“…Quantitative EEG analysis has been advocated to improve the sensitivity of EEG in detecting latent stages and for measuring subtle changes in the clinical grades of encephalopathy (17). However, visual EEG analysis scores have been found to correspond well with quantitative EEG (16,41), the difference being that the latter is amenable to statistical analysis and is better suited for comparative purposes (41).…”

New Methods of Testing and Brain Imaging in Hepatic Encephalopathy

“…44 It has been reported that there is prognostic value of the EEG findings for the development of HE and mortality in cirrhotic patients. 45 Marked improvement in EEG findings has also been demonstrated in the post-transplant setting 46 and may play a role in the evaluation of post-transplant neurologic complications. 47 …”

Clinical Neurophysiology of Hepatic Encephalopathy

“…Eye opening reactivity can be reduced analysis of the digitalized EEG provides grading based on the exact quantification of the EEG components. 7,10,14,15,[22][23][24][25] Based on the relative power of frequency bands and MDF over approximately 60 s of EEG over posterior derivations, a classification was obtained that has prognostic value both in terms of survival and risk of development of overt HE 14 ( Table 2). The value of such approach was recently confirmed 26 and a large, validated observational study proved that the use of the MDF of the EEG improves the predictive value of the MELD score.…”
