Psychological and neurodevelopmental outcome of high risk newborn infants
Insights
This study followed 111 high-risk newborns to age 3. Most outcomes were normal, but neurological sequels and developmental issues were significantly more common than in the general infant population.
Area of Science:
- Neonatal neurology
- Developmental pediatrics
- High-risk infant follow-up
Background:
- High-risk newborns face increased risks for neurodevelopmental deficits.
- Long-term outcomes require systematic monitoring to identify potential issues early.
Purpose of the Study:
- To assess the neurodevelopmental outcomes of high-risk newborns up to three years of age.
- To identify risk factors influencing long-term prognosis in this vulnerable population.
Main Methods:
- Longitudinal follow-up of 111 high-risk newborns to three years of age.
- Clinical assessment of neurological status and developmental milestones.
- Analysis of factors including neonatal cerebral distress and transient tone abnormalities.
Main Results:
- 71% of infants were normal; however, 28% exhibited neurological sequels or developmental abnormalities.
- Neonatal cerebral distress was strongly associated with poor neurodevelopmental prognosis (73.6%).
- Transient abnormalities of tone and socio-cultural factors also impacted developmental outcomes.
Conclusions:
- Systematic, long-term follow-up is crucial for high-risk newborns.
- These infants show a significantly higher incidence of neurological sequels and developmental abnormalities compared to normal infants.
- Early identification and intervention are vital for improving long-term outcomes.
Abstract:
Among 142 high-risk-newborns, 111 could be regularly followed-up to 3 years of age. 79 (71%) are normal, 6 (5.5%) have minor neurological sequels, 9 (8.1%) have major neurological sequels, associated in 4 cases with mental deficiency, 16 (14.5%) have developmental abnormalities (speech delay, behavioral problems, perceptual-motor and praxis disturbances), and one mental deficiency without neurological sequels. Neonatal cerebral distress proved to be the most dangerous clinical situation with regard to the ultimate neurodevelopmental prognosis (73.6% of neurological sequels or developmental abnormalities). The presence of transient abnormalities of tone in the course of the first year of life was associated with ultimate developmental abnormalities in 33.3% of the cases. Social and cultural status seemed to play a role in the intellectual, linguistic and perceptual-motor performance of this group of infants. In spite of these encouraging results, the need for a systematic long term follow-up of high risk newborns is stressed, since neurological sequels and developmental abnormalities are approximately 4 times more frequent in this group than in a normal infantile population.
