A report on revised terminology and concepts for organization of seizures and epilepsies proposed by International League Against Epilepsy (ILAE) Commission on Classification and Terminology in 2010 has revised concepts, terminology, and approaches for classifying seizures and epilepsy, aiming to establish the international consensus on classification and terminology, reflect the fundamental relation between the classification and the terminology, and provide guidance on making appropriate treatment protocols in clinical practice. Generalized seizures and focal seizures are redefined for seizures as occurring in bilaterally distributed networks (generalized) and within networks limited to one hemisphere (focal), respectively. Furthermore, genetic, structural-metabolic and unknown which represent modified concepts are used to replace idiopathic, symptomatic, and cryptogenic categories. Organization of forms of epilepsy is first described by specificity: electroclinical syndromes, constellation, and epileptic encephalopathies. This paper interprets the key changes in terminology and concepts for organization of seizures and epilepsies in the revised terminology and concepts for organization of seizures and epilepsies of the ILAE.
