Commission on Classification and Terminology
The history of classification has rested largely upon astute observations and expert opinions. First published in 1960 and last updated officially in 1981 for seizures (Commission on Classification and Terminology of the International League Against Epilepsy, 1981) and 1989 for epilepsies (Commission on Classification and Terminology of the International League Against Epilepsy, 1989), the ILAE classifications are based on concepts that, for the most part, predate modern neuroimaging, genomic technologies and concepts in molecular biology. The original authors foresaw that changes to the classification would be needed as new information was acquired and as new investigative technologies were developed. This is no simple task. Attempts have been made to update the 1989 and 1981 documents (Engel J, 2001, 2006); however no new proposal has been forthcoming.
During the current Commission’s term, input has been sought from experts in the genetics of epilepsy, neuroimaging, therapeutics, pediatric and adult epileptology, as well as statistics and research design. The goal has been to develop a methodologically and conceptually sound and clinically meaningful revision to the classification of the epilepsies and seizures.
