Abstract

Neonatal seizures are common, occurring in 2 to 5 of 1,000 live births in the United States. The neonatal brain is thought to be predisposed toward seizures due to a combination of excessive excitatory and deficient inhibitory neuronal activity. The seizures tend to be focal or multifocal without secondary generalization, resulting in subtle seizure appearance. There are five main categories of neonatal seizures: focal clonic, focal tonic, myoclonic, subtle, and generalized tonic. An electroencephalogram is recommended to diagnose and treat neonatal seizures due to poor reliability of the clinical examination. Causes of neonatal seizures are broad, including trauma, structural brain anomalies, infections, metabolic disorders, drug withdrawal or intoxication, and neonatal epilepsy syndromes. Treatment of neonatal seizures involves management of cardiorespiratory status, correction of metabolic derangements, and antiepileptics as needed. The most common antiepileptics used in neonates are phenobarbital, levetiracetam, and fosphenytoin. The long-term risk of neurodevelopmental disability varies depending upon the etiology of neonatal seizures. Close attention to developmental milestones and neurology follow-up is recommended for a...Continue Reading
