Proposal for Revised Classification of Epilepsies and Epileptic Syndromes

  author={Kayoko Yoshimura and Fumihiko Hamada and Ichiro Nomura and Takanobu Kurashige},
We reported results of a clinico-encephalographic study using proposal for classification of epilepsies and epileptic syndromes (1989 ILAE). Fifty-three patients belonged to localization-related epilepsies (LE) and syndromes; forty-one patients belonged to generalized epilepsies and syndromes (GE); one patient belonged to epilepsies and syndromes undetermined, focal or generalized; and we could not classify 4 patients. No patients with the onset after 2 years of age belonged to idiopathic LE… 

[Idiopathic generalised epilepsy. The value of semiology and EEG scanning in its classification].

The 2001 ILAE classification is more useful in order to classify patients with IGE because includes patients previously considered unclassifiable in the syndrome of generalised epilepsy with different phenotypes.

The revised classification scheme is generally useful for pediatric patients, but to make it more inclusive and clinically meaningful, some local customizations are required.

Classification of Epilepsies and Epileptic Syndromes in Young Children

Of the patients with LE, 47 had idiopathic, 35 symptomatic and 8 patients cryptogenic LE, 2 had a clear-cut syndrome of benign childhood epilepsy with centro-temporal spikes and one Childhood epilepsy with occipital paroxysms.

Neuroepidemiological Study of Childhood Epilepsy by Application of International Classification of Epilepsies and Epileptic Syndromes (ILAE, 1989)

Summary: A population‐based survey of childhood epilepsy was made in 1975 on the total population of children aged >10 years living in Okayama Prefecture (n = 2,378 patients). Using the data

Is the underlying cause of epilepsy a major prognostic factor for recurrence?

In adults, partial epilepsy is more difficult to treat than idiopathic generalized epilepsy, and in patients who have partial epilepsy, the location of the epileptogenic zone does not seem to be a determining factor.

Epidemiology of Idiopathic Generalized Epilepsies

IGEs are a relatively new category of disorders defined by strict clinical and electroencephalogram (EEG) features proposed by the International League Against Epilepsy (ILAE) classification of epileptic syndromes, but many epidemiologic studies still confuse the cryptogenic and idiopathic groups.

Experience with the International League Against Epilepsy Classifications of Epileptic Seizures (1981) and Epilepsies and Epileptic Syndrome (1989) in Epileptic Children in a Developing Country

Despite various limitations, the ILAE classification can be used in developing countries so that comparison can be made with other studies, and most cases were able to be classified.

Epilepsy syndromes: the 2022 ILAE definition and classification

The ILAE has approved the following definition of the epileptic syndrome: a characteristic cluster of clinical and EEG features, often supported by specific etiological findings (structural, genetic, metabolic, immune, and infectious)”.

Predictors of Outcome in Juvenile Myoclonic Epilepsy

The onset of JME at age <16 years, febrile seizures and epileptiform runs ≥3 s s might be associated with poor long-term seizure outcome in patients with JME.



Proposal for Revised Clinical and Electroencephalographic Classification of Epileptic Seizures

The history of the work which represents a milestone in efforts at classifying epileptic seizures and has led to world-wide adoption is related, and the majar portions of the version of the International Classification of Epileptic Seizures are proposed.
