Could the 2017 ILAE and the four-dimensional epilepsy classifications be merged to a new "Integrated Epilepsy...

Area of Science:

• Neurology
• Epileptology
• Clinical Classification Systems

Background:

• The International League Against Epilepsy (ILAE) classification for seizures and epilepsies (ILAE-EC) has undergone revisions to improve diagnostic accuracy and understanding of epilepsy etiology.
• Despite updates, the ILAE-EC has faced challenges in universal acceptance and routine clinical adoption.
• Concurrently, the "Four-dimensional epilepsy classification" (4D-EC) emerged, focusing on ictal symptomatology for seizure classification.

Purpose of the Study:

• To review and assess the concordance between the ILAE-EC and 4D-EC systems.
• To explore the feasibility of a unified classification system integrating the strengths of both approaches.
• To propose a novel "Integrated Epilepsy Classification" that bridges existing systems.

Main Methods:

• Comparative analysis of the ILAE-EC and 4D-EC systems.
• Review of historical arguments and evolving concordance between the two classification approaches.
• Development of a concrete proposal for an integrated classification framework.

Main Results:

• Past debates often highlighted incompatibilities between the ILAE-EC and 4D-EC, focusing on their respective shortcomings.
• A review reveals an evolving concordance between the two systems over time.
• A proposal for an "Integrated Epilepsy Classification" is presented, synthesizing elements from both systems.

Conclusions:

• An integrated epilepsy classification is feasible and desirable for improved clinical practice.
• The proposed "Integrated Epilepsy Classification" offers a compromise by incorporating key aspects of both the ILAE-EC and 4D-EC.
• This new framework aims to enhance usability and comprehensiveness in epilepsy diagnosis and management.
