Task Force On Classification
and Terminology Commission Members
|Jerome Engel, Jr., Chair
Buenos Aires, Argentina
New Hampshire, USA
This Taskforce was created to review the international classification for seizures and for epilepsies, and to recommend changes.
Commission Activities June 30, 2004 until August 31, 2005
The Classification Core Group met for the last time in Los Angeles 28-29 May 2005. Considerable progress was made in revising the Taskforce report and devising approaches for categorizing epileptic seizures and epilepsy syndromes. Subsequently, a final report was accepted by the Executive Committee and published in Epilepsia. It is important to recognize that the contents of this report do not represent a new classification, and that the 1981 Classification of Epileptic Seizure Types and the 1989 Classification of Epilepsy Syndromes will not be discarded unless, and until, clearly better classifications have been devised, although periodic modifications to the current classifications have been suggested. The new report has focused on establishing scientifically rigorous criteria for identification of specific epileptic seizure types and specific epilepsy syndromes as unique diagnostic entities, and plans for an evidence-based approach for future validation are outlined. The list of seizure types and syndromes included in this report should be considered as testable working hypotheses, subject to verification, falsification, and revision. If sufficient evidence subsequently becomes available to disprove any hypothesis, the seizure type or syndrome will be reevaluated and revised or discarded, with Executive Committee approval. This, therefore, represents an ongoing dynamic process, and a major purpose of this approach is to identify research necessary to clarify remaining issues of uncertainty, and to pave the way for new classifications. This is the final report of the Core Group of the Taskforce on Classification and Terminology, which completed its work in December 2005. A new Commission on Classification, chaired by Anne Berg, was formed in January 2006 and will continue these efforts.
