The ILAE has released an updated classification of epileptic seizures, building upon the framework established in 2017. The update, published in Epilepsia, aims to enhance clarity, consistency, and clinical utility across global settings.
The revised classification includes four main seizure classes and 21 seizure types—down from 63 in the 2017 version. Key updates include the use of “consciousness” over “awareness,” a focus on observable features, and a clear distinction between classifiers and descriptors.
The changes support improved clinical communication, research, and patient understanding. The update was shaped by global expert consensus, public feedback, and a rigorous review process.
