Predictability of cerebral palsy in a high-risk NICU population
Insights
This study developed a predictive model to identify infants at high risk for cerebral palsy (CP). The model uses perinatal factors and brain imaging to accurately predict CP development in newborns.
Area of Science:
- Neonatal neurology
- Pediatric neurology
- Medical imaging
Background:
- Cerebral palsy (CP) is a leading cause of motor disability in children.
- Early identification of high-risk infants is crucial for timely intervention.
- Predictive models can improve risk assessment for CP.
Purpose of the Study:
- To develop a predictive model for individual risk assessment of cerebral palsy (CP).
- To identify key perinatal characteristics and neonatal brain injuries associated with CP development.
Main Methods:
- A cohort of 1099 NICU-admitted high-risk infants was studied up to 12 months corrected age.
- Logistic regression analysis was used, incorporating perinatal data and neonatal cerebral ultrasound findings.
- CP was categorized by subtype, distribution, and severity.
Main Results:
- Independent predictors for CP included perinatal asphyxia, prolonged mechanical ventilation, white matter disease, intraventricular hemorrhage (grades III-IV), cerebral infarction, and deep gray matter lesions.
- The model achieved 95% accuracy in identifying children with CP at a 4.5% probability cut-off.
- Specific factors predicted CP subtypes: gestational age, asphyxia, and deep gray matter lesions for non-spastic vs. spastic CP; gestational age, cerebral infarction, and parenchymal hemorrhagic infarction for unilateral vs. bilateral spastic CP; asphyxia for severe vs. mild/moderate CP.
Conclusions:
- A predictive model integrating perinatal factors and neonatal ultrasound-detected brain injuries effectively identifies infants at risk for CP.
- This tool aids in pinpointing specific high-risk infants for targeted management.
Aim:
This study aims to create a predictive model for the assessment of the individual risk of developing cerebral palsy in a large cohort of selected high-risk infants.
Patients And Methods:
1099 NICU-admitted high-risk infants were assessed up to the corrected age of at least 12 months. CP was categorized relative to subtype, distribution and severity. Several perinatal characteristics (gender, gestational age, multiple gestation, small for gestational age, perinatal asphyxia and duration of mechanical ventilation), besides neonatal cerebral ultrasound data were used in the logistic regression model for the risk of CP.
Results:
Perinatal asphyxia, mechanical ventilation>7 days, white matter disease except for transient echodensities<7 days, intraventricular haemorrhage grades III and IV, cerebral infarction and deep grey matter lesions were recognized as independent predictors for the development of CP. 95% of all children with CP were correctly identified at or above the cut-off value of 4.5% probability of CP development. Higher gestational age, perinatal asphyxia and deep grey matter lesion are independent predictors for non-spastic versus spastic CP (OR=1.1, 3.6, and 7.5, respectively). Independent risk factors for prediction of unilateral versus bilateral spastic CP are higher gestational age, cerebral infarction and parenchymal haemorrhagic infarction (OR=1.2, 31, and 17.6, respectively). Perinatal asphyxia is the only significant variable retained for the prediction of severe CP versus mild or moderate CP.
Conclusion:
The presented model based on perinatal characteristics and neonatal US-detected brain injuries is a useful tool in identifying specific infants at risk for developing CP.
