EEG changes in patients with intracranial tumors and seizures symptom at Mohammad Hoesin Hospital Palembang

This study was conducted to determine the EEG changes in intracranial tumor patients with symptoms of seizures and the correspondence between the location of tumor by the location of the EEG abnormality. This is a cross-sectional descriptive study using primary and secondary data. Samples were collected consecutively over a period of 1 year. Of the 35 samples, abnormal EEG in patients with primary intracranial tumors obtained 68,2%, whereas in metastatic intracranial tumors obtained in 84,6%. From the abnormal EEG, in primary intracranial tumors description focal slowing in 60.0%, epileptic activity 20.0%, accompanied focal epileptic activity and focal slowing in 13.3%. Whereas in patients with intracranial tumor metastasis overview the form of a focal slowing in 36.4%,epileptic activity in 18.2%, and deceleration focal epileptiform activity accompanied by 45.5%. Presence of the EEG abnormality locations in tumor area 23.1%, non-tumor area by 38.5%, tumor and non-tumor area area by 38.5%. In this study, most patients have an abnormal EEG which more common in the form of a focal slowing compared epileptic activity, and some abnormalities are located in non-tumor areas. This indicates that the seizures that occur may be more due to irritation lesions than for the formation of epileptic focus.
