A novel approach to seizures in neonates

Recognition of seizures in neonates remains the foremost challenge to overcome. All neonates at risk for seizures, especially the critically ill, should undergo video-EEG monitoring. The initial step toward an accurate diagnosis is the accurate description and interpretation of the electro-clinical phenotype. THE IMPORTANCE OF SEIZURE SEMIOLOGY AND ASSOCIATION WITH ETIOLOGY: The early distinction between acute provoked seizures and neonatal-onset epilepsies serves as the primary determinant for guiding management, treatment choices, and duration. Seizures in neonates should be seen as a symptom, not a disease, and their semiology may suggest the etiology.

Neonates with hypoxic-ischemic encephalopathy respond best to phenobarbital, while levetiracetam is a better choice for neonates with congenital heart diseases. Anti-seizure medication can be discontinued after 72 h of seizure freedom, before discharge from the hospital.

Neonates with epilepsy usually require a personalized, etiology-based approach in terms of choice and duration of treatment. Neonates with channelopathies tend to respond to sodium channel blockers such as carbamazepine, oxcarbazepine, or phenytoin. The surgical option should be considered early in cases of large brain malformations, such as hemimegalencephaly.
