title: Significance of seizures in very low-birthweight infants.
abstract: Of 506 very low-birthweight (VLBW) infants, the authors review data on 67 identified as having seizures. 29 survivors with seizures and 305 without were followed up at the ages of one, two and five years: statistical significance of psychological and mental impairment was evaluated. Impairment was higher in the seizure group at 66 per cent (15 per cent in non-seizure group) and 43 per cent of these were considered to be severely impaired. Infants with seizures occurring for more than seven days and lasting for more than five minutes had the poorest outcome, and infants with late onset had the best outcome. Analysis showed that 40 per cent of seizures were caused by birth asphyxia, and these were strongly prognostic, correlating with mortality and impairment rates. 60 per cent of the infants who died had the same cause for both their seizures and death, and for 57 per cent of these the cause was perinatal asphyxia. The poor outlook for the VLBW infants suggests that the seizures themselves are a serious neurological insult.
