Overt neonatal seizures: outcome at one year

Area of Science:

• Neonatal neurology
• Pediatric neurology
• Developmental neuroscience

Background:

• Neonatal seizures represent a critical neurological event in infants.
• Understanding long-term outcomes is crucial for clinical management and parental counseling.

Purpose of the Study:

• To investigate the survival rates and neurodevelopmental outcomes of infants experiencing seizures in the neonatal period.
• To identify factors associated with mortality and neurological sequelae in this cohort.

Main Methods:

• Longitudinal follow-up of 65 infants with neonatal seizures to one year of age.
• Multivariate stepwise analysis to identify significant predictors of outcomes.
• Assessment of mortality (neonatal and postneonatal) and neurological status at one year.

Main Results:

• 27 out of 65 infants did not survive to one year.
• Low birthweight and the number of anticonvulsants used were significantly associated with nonsurvival.
• Longer seizure duration was linked to neurodevelopmental sequelae in survivors.
• 13.2% of survivors experienced seizures at one year of age.

Conclusions:

• Neonatal seizures have a substantial impact on infant mortality and long-term neurological health.
• Risk factors like low birthweight and seizure characteristics necessitate targeted interventions.
• Early identification and management of neonatal seizures are vital for improving neurodevelopmental outcomes.
