Classification of seizures

The ILAE Classification of the Epilepsies was updated in 2017[1][2] to reflect the advances made in recent years in the understanding of the epilepsies and their pathophysiologies since the classification was last ratified in 1989[3]. The current classification is based on the 1981 classification[4] which was extended in 2010[5]. It addresses the three levels of (1) identifying epilepsy (2) identifying the epilepsy type and (3) identifying the epilepsy syndrome where possible. In addition at each level it takes into account the aetiological diagnosis.
