The International League against Epilepsy (ILAE) published, in the April 2017 edition of Epilepsia, three companion articles on the classiﬁcation of seizures and the epilepsies. These represent a long-awaited update on the original 1981 and 1989 publications and provide a modern descriptive template.
The new classiﬁcation presents three levels of terminology, involving seizure types, epilepsy types, and syndromes. In this fourth paper, we present an interpretation of these new concepts for people with epilepsy and those who care for them, as well as for young medical doctors not specialized in epilepsy and nurses. My goal, as President of the IBE, in writing this paper is to ensure that everyone is speaking and understanding the same language, which is fundamental to the optimal management of people with epilepsy.
