The classification of childhood seizures and epilepsy syndromes. The classification of seizures and the epileptic syndromes is particularly relevant to those who treat children, as most syndromes are age related, with onset between the neonatal and adolescent periods. Whereas seizures are characterized by ictal behavior and EEG findings, epilepsy syndromes are defined by seizure type, etiology, age of onset, natural history, possible genetic factors, and prognosis. Limitations exist, but attempts to use these classifications typically lead to a better understanding of the patient and allow for more precise evaluation and treatment.
