Neuromotor development of graduates of the neonatal intensive care unit: patterns encountered in the first two years of life.
The neurodevelopmental course of 219 Neonatal Intensive Care Unit graduates followed prospectively over 2 years was determined on retrospective chart review. Mild neuromotor abnormalities during the first year were identified in 50%, three-quarters of which proved transient with normal development at 2 years of age. Moderate abnormalities were identified in 7%, half of which proved transient. Severe neuromotor abnormalities were identified in 20%, two-thirds of whom had cerebral palsy at 2 years. Persistent noncerebral palsy neuromotor abnormalities remained in one-third of those in the severe abnormality group, one-half of those in the moderate abnormality group, and one-quarter of those in the mild abnormality group. As birthweight decreased, the incidence of always normal development and transient neuromotor abnormalities decreased while the incidence of persistent neuromotor abnormalities increased. Small for gestational age infants demonstrated a slightly higher incidence of persistent abnormalities than their appropriate for gestational age counterparts. No significant sex differences were observed.
