Seizure classifications across the years: A translation table

Abstract In 2025, the International League Against Epilepsy introduced a revised seizure classification, building on user feedback and increased knowledge of seizure mechanisms, as an update to the 1981 and 2017 classifications previously established. Given the expectation of slow adoption, with continued use of the previous terminology in published literature, education, regulatory bodies, and even clinical practice, we provide a translation table of seizure terminology classifications.
