The journey from survival to thriving begins in the Neonatal Intensive Care Unit. As we witness remarkable advances in neonatal care, our focus has evolved beyond immediate survival to encompass the quality of life and long-term developmental outcomes of our most vulnerable patients. This presentation explores comprehensive approaches to neurodevelopmental assessment, highlighting the critical importance of early identification, systematic evaluation, and comprehensive follow-up for high-risk newborns.
"Every child deserves the opportunity to reach their full developmental potential"
Five decades of remarkable progress in neonatal neurodevelopmental care
Key Point: Shift from just survival to quality of life
Key Point: Standardized protocols across centers
Key Point: First modern standardized assessment tool
Key Point: Current gold standard (excludes at-risk from norms)
From "Will they survive?" to "How well will they develop?"
50 years of progress = Better survival + Better quality of life
Increase in Extremely Low Birth Weight survival since 1980s
26-27 week survival now >85%
Reduction in severe neurodevelopmental impairment with modern care
Therapeutic interventions proven effective
Programs now include family-centered care
Parents as essential team members

Focus on Survival → Developmental Support → Family Partnership → Individualized Outcomes
From treating disease to optimizing each child's potential
Comprehensive criteria and outcome data for at-risk newborns
A high-risk infant is any neonate who has an increased chance of morbidity or mortality due to conditions or circumstances associated with birth and the perinatal period.
These infants require specialized follow-up through High-Risk Infant Follow-up (HRIF) programs to monitor neurodevelopmental outcomes
| Gestational Age | Survival Rate | Neurodevelopmental Impairment in Survivors | Cerebral Palsy | Median LOS |
|---|---|---|---|---|
| 22 weeks | 10-30% | 40-50% | 25-35% | >120 days |
| 23 weeks | 30-50% | 30-40% | 20-30% | 100-120 days |
| 24 weeks | 50-70% | 25-35% | 15-25% | 80-100 days |
| 25 weeks | 70-85% | 20-30% | 10-20% | 60-80 days |
| 26-27 weeks | 85-90% | 15-25% | 8-15% | 40-60 days |
Recommendation: Include late preterm infants in structured follow-up programs

| Grade | Description | Cerebral Palsy Risk | Cognitive Risk |
|---|---|---|---|
| Grade I-II | Minor hemorrhage | 5-10% | 5-10% |
| Grade III | >50% ventricular filling | 25-35% | 30-40% |
| Grade IV (PVHI) | Periventricular hemorrhagic infarction | 50-70% | 60-80% |
Note: Progressive ventricular dilatation requiring intervention: 40-60% major neurodevelopmental impairment
20-30% Cerebral Palsy risk
25-40% learning difficulties
60-90% spastic diplegia
70-85% cognitive impairment
Medical Necrotizing Enterocolitis: 15-25% increased neurodevelopmental impairment risk
Surgical Necrotizing Enterocolitis: 30-45% increased risk
Short gut syndrome: 50-70% developmental delays and growth problems
Neurodevelopmental abnormalities
60-90%Developmental delays
30-50%ADHD, learning disabilities

Best combined with General Movements Assessment for optimal prediction
Brain development continues at the same rate whether inside or outside the womb. A baby born at 28 weeks has missed 12 weeks of crucial brain development compared to a term baby.
Using chronological age would unfairly compare a premature baby to term babies. Corrected age ensures we assess development based on the expected maturation level.
Corrected age is typically used until 24 months (or 36 months for very preterm infants)
Born at: 28 weeks
Current age: 6 months
Prematurity: 12 weeks
Corrected Age = 3 months
Born at: 32 weeks
Current age: 18 months
Prematurity: 8 weeks
Corrected Age = 16 months
