The changing patterns of neurologic and developmental functioning between 1 and 7 years of age were studied in very low-birth-weight infants (birth weight ≤1,500 g). Subjects included 42 infants born in 1975 who were followed for 7 years. Based on the 1-year neurologic assessment, 22 infants were classified as normal, 12 as suspect, and eight as abnormal. The three groups did not differ in birth weight, gestational age, sex, or Hollingshead socioeconomic status (SES) score. The neurologic findings at 7 years of age were significantly related to the neurologic examination findings at 1 year of age. Seventy-seven percent of the normal group, 58% of the suspect group, and 100% of the abnormal group remained in the same neurologic category at 7 years of age. Children in the abnormal group had the greatest improvement in cognitive functioning between 1 and 7 years of age but did not achieve the IQ level of children in the normal group. Forty-five percent of the normal group, 75% of the suspect group, and 100% of the abnormal group had poor visual-motor integration. Fifty-eight percent of the suspect group and 87% of the abnormal group were reading below age level. Of the total sample, 54% required special education or resource help at 7 years of age, and the three groups differed significantly in their need for a special educational plan ( P .05). These data indicate that a neurologic classification at 1 year of age provides a guide for monitoring very low-birth-weight infants and can be helpful in alerting school personnel to potential needs.
