Introduction: Epilepsy is a neurological disorder marked by sudden recurrent episodes of sensory disturbance, loss of consciousness, or convulsions, associated with abnormal electrical activity in the brain. Epileptic seizures are episodes that can vary from brief and nearly undetectable to long periods of vigorous shaking. These episodes can result in physical injuries to the patients. Aim: To study the correlations of CT scan Brain and EEG in epileptic patients. Materials and methods: This study was done at Mahatma Gandhi Memorial Hospital (MGM), Warangal, and Telangana State. Duration of the study is from 2002 to 2003.The patients admitted with seizures were included after considering the exclusion of metabolic causes and infective causes. The seizures in these patients were classified as per the classification of International classification of epileptic seizures. Results: Out of 150 cases subjected to CT scan brain 90 (60 %) cases were normal and 60 cases (40%) showed focal lesions on CT scan. All 150 patients of epilepsy were subjected to EEG which was recorded using 18-channel instrument, Normal EEG was observed in 83 cases (55%), and Generalized epileptic potentials were seen in 41 cases (27.3%) and epileptic foci was seen in 26 cases (17.3%). Conclusion: A significant correlation was observed between focal EEG changes and focal lesions in CT scan brain.
