Background
Previous studies of very preterm (VPT) infants have shown a wide range of seizure prevalence and association with intraventricular hemorrhage (IVH), white matter injury (WMI), and death. However, the impact of seizures on neurodevelopment is not well known. We hypothesized that seizures in the first 3 d after VPT birth would be associated with increased radiographic brain injury and later neurodevelopmental risk.

Methods
For 72 h after birth, 95 VPT infants underwent amplitude-integrated electroencephalogram monitoring. High and low seizure burdens were related to radiographic brain injury, death in the neonatal period, and children’s Bayley III (Bayley Scales of Infant Development) performance at 2 y corrected age in a subgroup of 59 infants.

Results
The overall incidence of seizures in this sample was 48%. High seizure burden was associated with increased risk of IVH on day 1; IVH, WMI, and death on day 2; and high-grade IVH on day 3. The presence of seizures on any day was associated with decreased language performance at age 2, even after controlling for family social risk.

Conclusion
Seizures during the first 3 d after birth are common and are associated with an increased risk of IVH, WMI, and death. They were also associated with poorer early language development.
