    Abstract:
    A new neonatal neurobehavioral examination (NNE) was designed in response to the need for a more quantitative assessment of neonatal neurological status. The NNE consists of 27 items divided into three sections: 1) tone and motor patterns, 2) primitive reflexes, and 3) behavioral responses. Each section consists of 9 items scored on a three-point scale. Fifty-four healthy full-term infants were examined at 2 days of age and demonstrated total NNE scores ranging from 70 to a maximum possible score of 81 (X = 76, s = 1.03). Mean section scores for these infants ranged from 25.3 to 26.6 (s = .59-1.79). Intertester agreement was 88% by item and 95% by total score in each section. Two hundred ninety-eight high-risk infants were then examined at 37 to 40 weeks conceptional age (gestational age plus chronological age) or at discharge from the neonatal intensive care unit, whichever occurred first. Total NNE mean scores for high-risk infants fell into discrete clusters by conceptional age at the time of examination (37-42 weeks, mean score = 66.5; 34-36 weeks, mean score = 60.7; less than 34 weeks, mean score = 51.1). Similar clustering occurred for the three section scores. Highly significant differences existed between the three conceptional age groups for total scores and section scores. No clinically significant score differences were associated with severity of illness or gestational age at birth. The results of this study suggest that the NNE easily and reliably assesses infants' neonatal neurobehavioral status at a given conceptional age. Additional studies are in progress to determine the value of the NNE in predicting subsequent developmental disabilities.
