Neonatal Seizures: Diagnosis, Etiologies, and Management

Area of Science:

• Neonatal neurology
• Pediatric epilepsy
• Clinical neurophysiology

Background:

• Neonates possess unique physiological factors and risks tied to gestation, delivery, and the postnatal period, rendering them highly susceptible to seizures.
• Identifying neonatal seizures is challenging, necessitating a high index of clinical suspicion based on history or encephalopathy, with or without abnormal movements.

Purpose of the Study:

• To review the challenges in identifying and classifying neonatal seizures.
• To discuss the distinct etiologies of acute symptomatic neonatal seizures versus neonatal-onset epilepsy.
• To highlight the importance of early diagnosis and treatment for optimizing outcomes.

Main Methods:

• Literature review of neonatal seizure pathophysiology, diagnosis, and management.
• Analysis of current understanding of acute symptomatic seizures and neonatal-onset epilepsies.
• Discussion of emerging trends in genetic medicine and personalized treatment approaches.

Main Results:

• Neonatal seizures stem from acute brain injury or underlying structural, metabolic, or genetic disorders.
• Initial acute treatment strategies are similar, but long-term prognosis depends heavily on the seizure's cause.
• Genetic advancements are enhancing the understanding and personalized treatment of neonatal-onset epilepsies.

Conclusions:

• Early identification and prompt treatment are vital for improving outcomes in acute symptomatic neonatal seizures.
• Further research is needed to define optimal seizure control and treatment duration.
• Personalized medicine, driven by genetic discoveries, holds promise for improving outcomes in this vulnerable population.
