Clinical use of Electroencephalography in the Diagnosis of Partial Seizures
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 2
Abstract
Introduction: Electroencephalography (EEG) remains the most important investigative modality in the diagnostic evaluation individuals with epilepsy. Although the diagnosis of epilepsy is clinical, EEG helps establish the diagnosis of epilepsy, distinguish epileptic seizures from other non-epileptic events, determine the site of seizure origin and the classifi cation of epilepsy and epilepsy syndromes. Aim: The aim was to study the role of EEG in localizing the lesion in partial seizure and to identify clinical clues which predict a structural lesion in partial seizure. Materials and Methods: Prospective observational study was conducted in Department of Neurology, Government Rajaji Hospital, Madurai. Detailed history and clinical examination are carried out to ensure the organic nature of epilepsy. EEG and computed tomography (CT) were done; results are critically analyzed for the presence of focal, localized, or generalized changes by montage-wise analysis. Conclusion: Even though yield of EEG in making a diagnosis in epilepsy is low-lateralizing changes and localizing if present gives more idea of the presence of a structural lesion in the brain.
