Neonatal Seizures: Core Concepts
Seizures are the abnormal, excessive, synchronous discharge of cortical neurons that results in injury to the brain. Seizures presenting in the neonatal period may be the first and only clue to underlying neurological pathology. Despite advances in care, the mortality rate for infants experiencing neonatal seizures is still as high as 20 percent, with up to 65 percent of infants with seizures demonstrating significant morbidity. Early identification and treatment of the seizure or modifiable underlying etiology greatly reduces the extent of morbidity associated with neonatal seizures. Literature, including journal articles and relevant textbooks, was reviewed and condensed into a practical guide to neonatal seizures which includes the pathophysiology of injury associated with neonatal seizures, clinical manifestations, methods of diagnosis, and various options available for treatment.
