ILAE 1989 Neonatal seizures Neonatal seizures differ from those of older children and adults. The most frequent neonatal seizures are described as subtle because the clinical manifestations are frequently overlooked. These include tonic, horizontal deviation of the eyes with or without jerking, eyelid blinking or fluttering, sucking, smacking, or other buccal-lingual oral movements, swimming or pedaling movements and, occasionally, apneic spells. Other neonatal seizures occur as tonic extension of the limbs, mimicking decerebrate or decorticate posturing. These occur particularly in premature infants. Multifocal clonic seizures characterized by clonic movements of a limb, which may migrate to other body parts or other limbs, or focal clonic seizures, which are much more localized, may occur. In the latter, the infant is usually not unconscious. Rarely, myoclonic seizures may occur, and the EEG pattern is frequently that of suppression-burst activity. The tonic seizures have a poor prognosis because they frequently accompany intraventricular hemorrhage. The myoclonic seizures also have a poor prognosis because they are frequently a part of the early myoclonic encephalopathy syndrome.
