Definition & Classification
Current Definitions and Classifications
The ILAE strives to provide definitions for key concepts and classification schemes that will help the world epilepsy community in developing a common language to communicate effectively regarding the many facets of epilepsy. It is also hoped that the clear terminology, based on available evidence, will help develop treatments adapted to each condition.
