ILAE classification of epilepsy syndromes

The efforts of the International League against Epilepsy (ILAE) to devise classifications of the epilepsies has greatly improved communication among epileptologists and influenced both basic and clinical research. Several classifications have been proposed since 1970; the most recent classification of epilepsy syndromes and epilepsies was published in 1989. Since 1997, the ILAE Task Force on Classification and Terminology has been evaluating this classification and some modifications have been recommended. Although the 1989 classification can be criticized and needs to be updated, it has been widely accepted and is universally employed. Consequently, the Task Force has agreed not to propose a replacement until a clearly better classification can be created. (c) 2006 Elsevier B.V. All rights reserved.
