[Neurologic outcomes for infants weighing less than 1,000 grams at birth].

We evaluated the neurologic outcomes of 107 infants with birth weights of less than 1,000g who had been admitted to our hospital from October 1981 to March 1986. Their outcomes were confirmed during a follow-up period of 20-39 years (mean: 75 years). The diagnoses were normal in 71, cerebral palsy in 13, mental retardation in 11, borderline intelligence in 11, and spinal palsy due to birth injury in 1. Only 3 infants with cerebral palsy had developed epilepsy. Among the infants with birth weights of less than 1,000g hospitalized in this tertiary care center, about one-third still had some major or minor neurologic abnormalities.
