ABSTRACT

Introduction: The currently accepted classification of the International League Against Epilepsy is not a semiologic classification of the epileptic seizures. Objective: To determine whether it is possible to obtain a semiologic classification of the epileptic seizures based on history taking and by this, to estimate location and laterality of the epileptic zone. Methods: A cross-sectional multicenter double-blind study was performed on 189 patients referred to surgical evaluation from 2007 to 2011. A standardized-structure questionnaire and video-telemetry was used to collect the main information. Results: Auras, focal seizures, aphasia, ictal psychosis, postictal confusion, head version, hemicranea and peri-ictal amnesia allowed identification of the seizures onset. The time sequence in which typical temporal auras appeared, focal frontal seizures followed by focal or generalized hemiconvulsion, or with lower-limb automatisms without oral automatisms associated with confusion, depression and the existence of a latency period allowed clear differentiation of epileptic zone. Conclusion: Peri-ictal symptoms evaluated by video-EEG can be obtained by a detailed history taking, which associated with seizures signs and symptoms and analyzed in strict temporal order could allow estimation of the laterality and location of the epileptic zone.
