This chapter focuses on the classification of seizures and epilepsy syndromes based on the International League Against Epilepsy's classification systems from 1981 and 1989, respectively, which are still used today in clinical practice and have formed the basis for a worldwide standardized approach to diagnosing, treating, and studying seizure disorders. This classification system is based on clinical seizure semiology and EEG correlation and makes a distinction between focal and generalized seizures. The clinical semiology and localization of simple partial, complex partial, and generalized seizures are discussed. Some common partial and generalized epilepsy syndromes are also highlighted.
