<![CDATA[Background: Electrolyte imbalances can manifest with diffuse brain dysfunction, seizure and consequently EEG abnormalities. Electrolyte disturbances is crucial for assessing the level of EEG abnormality. Objective: This study investigated the difference in the level serum electrolyte in idiopathic and symptomatic epilepsy. It also correlated the serum electrolyte levels with abnormality EEG. Methods: This is an analytical observational study employing a cross-sectional design. The study analyzed secondary data collected from medical records of patients who fulfilled the inclusion and exclusion criteria. The subjects are all epileptic patients undergoing EEG examination at Gambiran General Hospital from June-August 2024. The subject was grouped into idiopathic and symptomatic epilepsy. The results of EEG were grouped into normal, abnormal II and III. The examination of serum electrolyte levels was conducted on within one hour before the EEG examination. Results: We recruited 90 subjects (38 males and 52 females) were diagnosed epilepsy, 65 idiopathic and 25 symptomatic. The age 12-68 years old. Among 90 patients, 69 had normal EEG and 21 had abnormal EEG (8 abnormal II and 13 abnormal III). Only the mean serum calcium in symptomatic epilepsy patients was higher than in the idiopathic (2,32±0,39 mmol/L vs 2,23±0,34 mmol/L). All of the mean serum electrolyte was lower in patient with abnormal EEG than the normal one. Kruskal-Wallis Correlation Test showed no significant difference between mean serum electrolyte levels with EEG result. Conclusion: There is no relationship between serum electrolyte levels with abnormality EEG in idiopathic and symptomatic epilepsy patients.]]>
