Abstract :

Objective: To study the EEG changes in patients with hepatic encephalopathy (HE) and correlate them according to the grade of encephalopathy. Method: This study was carried out at Civil Hospital, Ahmedabad from January 2014 to October 2015. A total 35 patients with hepatic encephalopathy were taken and examined for clinical and laboratory parameter. EEG recording was done for every patient with standard international 10–20 electrode placement system. Data was analyzed and results obtained. Results: 7 (20%) patients had grade 1 hepatic encephalopathy, 11 (31.42%) patients had grade 2 HE, 11 (31.42%) patients had grade 3 HE and 6 (17.14%) patients had grade 4 HE. In EEG finding, alpha wave was in majority in grade 1 HE (85.71%). Grade 2 HE predominantly had theta wave (81.82%), grade 3 HE had predominantly triphasic wave (81.82%) and delta wave was predominant in grade 4 HE. Conclusion: As the grade of hepatic encephalopathy increases frequency of wave decreases and waves with slower frequency i.e. theta, delta or triphasic wave begin to appear in EEG. Further studies are required in community on large scale, for the analysis of EEG changes in patients with hepatic encephalopathy
