Our current description of seizures is guided by the 2017 International League Against Epilepsy, (ILAE) revised classification of seizure types. A seizure is first described by type of onset, which includes focal, generalized, or unknown. A seizure of unknown onset may have defining characteristics; however, due to lack of information, it cannot be confidently classified as focal or generalized.
