To clarify the characteristics of localization-related epilepsies in early infancy, we performed an electroclinical study of 28 epileptic patients whose first seizures occurred before 6 months of age. The patients were retrospectively divided into two groups: the seizure-controlled group (8 patients) and the refractory group (20 patients). The seizure-controlled group included the patients whose seizures were suppressed within 1 year after onset; the refractory group included all other patients. The characteristics of the refractory group were as follows: (1) most patients had serious underlying pathologies; (2) the seizure type in most cases was simple partial seizure or complex partial seizure without secondary generalization; (3) the interictal EEG showed focal abnormalities and severe dysrhythmia on the basic pattern associated with multifocal spikes in most cases; and (4) in some patients, West syndrome developed after localization- related epilepsies and generalized seizures appeared later in some cases.
