Once epilepsy is diagnosed, the [[International League Against Epilepsy|ILAE]] recommends a three-level framework to guide further classification and management:<ref name="Scheffer2017" />

* Identify the seizure type, based on clinical features and EEG (e.g., focal aware seizure, generalized absence)
* Determine the epilepsy type, such as focal, generalized, combined, or unknown
* Identify an epilepsy syndrome, if applicable

Not all levels can always be determined; in some cases, only the seizure type is identifiable. The etiology — whether structural, genetic, infectious, metabolic, immune, or unknown — should be considered at each stage of classification, as it often influences treatment and prognosis.<ref name="2011rec">{{cite journal |vauthors=Shorvon SD |date=June 2011 |title=The etiologic classification of epilepsy |journal=Epilepsia |volume=52 |issue=6 |pages=1052–1057 |doi=10.1111/j.1528-1167.2011.03041.x |pmid=21449936 |doi-access=free}}</ref><ref name="Scheffer2017" />
