Seizures can be the most dramatic indication of neurologic abnormality in the newborn, yet most neonatal seizures are subtle or even silent. There are five types of neonatal seizures: subtle seizures (presenting with apnea, starring, lip smacking, chewing or eye blinking); focal clonic; multifocal clonic; tonic, and myoclonic seizures. The causes of neonatal seizures include metabolic, toxic, structural and infectious diseases.
