Classification of epileptic seizures and the epilepsies.

Recent activity in the classification of epileptic seizures and in the classification of the epilepsies has been based on the ability to identify accurately (1) individual seizure types, (2) the progression of one type of seizure into another during the course of a single seizure, and (3) the repertoire of different seizures and other symptoms allowing the identification of epileptic syndromes. Much of this activity has resulted from the technologic advances in video recording, long-term electroencephalographic monitoring, and the incorporation of both into the clinical armamentarium.
