[Neurodevelopmental examination of high risk infants (author's transl)]
Insights
A new standardized neurological exam for high-risk infants shows significant differences between full-term and premature babies. This tool helps assess neurological function, with scores improving by six months, indicating developmental catch-up.
Area of Science:
- Neonatal neurology
- Developmental pediatrics
- High-risk infant assessment
Context:
- Modern neonatal intensive care improves outcomes for high-risk infants.
- Premature birth, low birthweight, and perinatal complications remain significant risk factors for neurological sequelae.
- Existing assessment methods yield variable neurological sequelae rates (4.4-28%) in high-risk infants.
Purpose:
- To introduce a new standardized neurological examination for high-risk infants.
- To evaluate neurological function, maturation, and integrity in infants.
- To compare neurological status between full-term and premature infants, and between those with minimal risk versus perinatal brain distress.
Summary:
- A cohort of 163 high-risk infants was assessed at 3 and 6 months corrected age using a novel neurological examination based on Touwen's (1976) and Prechtl's (1968) concepts.
- Statistically significant differences in neurological status were observed between full-term and premature infants, and between infants with minimal risk and perinatal brain distress.
- A rapid increase in neurological optimality scores by 6 months suggests significant self-repair or maturational catch-up in the infant nervous system.
Impact:
- Highlights the need for effective screening instruments to evaluate neurological development in high-risk infants.
- Provides evidence for distinct neurological trajectories in premature versus full-term infants.
- Suggests that while extrauterine stimulation may not accelerate brain function development in preemies, it might influence maturation rates.
Abstract:
While the high risk infants' prognosis for normal development has been greatly improved by modern neonatal intensive care, premature birth, low birthweight and perinatal complications involving compromised brain function still represent major risk factors. Different criteria for admission and assessment methods are the reason that recent publications cite neurological sequelae in high risk infants that range from 4.4 to 28%. The need for an effective screening instrument enableing the pediatrician to test and evaluate neurological function, maturation and integrity, is quite obvious. The author has selected a group of neurological items according to results of Touwen's (1976) longitudinal study on neurological maturation in infancy. In addition, Prechtl's (1968) optimality concept was applied in our study. This new standardized neurological examination was used to evaluate 163 high risk infants with a corrected age of 3 and 6 months. The results demonstrate statistically significant differences between the neurological status of full-term and premature infants, and similarly between those with minimal risk and perinatal brain distress. The rather steep increase of neurological optimality scores by age of 6 months implies a high rate of self-repair or catch-up in maturation of the nervous system. We speculate that early extrauterine stimulation of the premature does not accelerate the development of brain function in a similar way as it does other organ functions, but it may slow down maturation.
