ILAE_1989_2.3_Symptomatic_Generalized_Epilepsy_Syndrome

ILAE 1989 Symptomatic generalized epilepsies and syndromes Symptomatic generalized epilepsies, most often occurring in infancy and childhood, are characterized by generalized seizures with clinical and EEG features different from those of idiopathic generalized epilepsies. There may be only one type, but more often there are several types, including myoclonic jerks, tonic seizures, atonic seizures, and atypical absences. EEG expression is bilateral but less rhythmical than in idiopathic generalized epilepsies and is more or less asymmetrical. Interictal EEG abnormalities differ from idiopathic generalized epilepsies, appearing as suppression bursts, hypsarrhythmia, slow spike-waves, or generalized fast rhythms. Focal abnormalities may be associated with any of the above. There are clinical, neuropsychologic, and neuroradiologic signs of a usually diffuse, specific, or nonspecific encephalopathy.
