Perinatal cerebral insults: hemorrhage and ischemia
Insights
Major neurodevelopmental handicaps in special care survivors remain unchanged despite advanced perinatal care. Infants with intraventricular hemorrhage or cerebral infarction face higher risks for abnormalities.
Area of Science:
- Neonatal neurology
- Developmental pediatrics
- Perinatal medicine
Background:
- Neurodevelopmental handicaps persist in special care survivors.
- Advanced perinatal care has not reduced handicap incidence.
- Intraventricular hemorrhage and cerebral infarction are key risk factors.
Purpose of the Study:
- To review the incidence of neurodevelopmental handicaps in special care survivors.
- To identify risk factors associated with these handicaps.
- To explore the role of cerebral blood flow alterations.
Main Methods:
- Review of existing literature and clinical data.
- Analysis of neurodevelopmental outcomes in high-risk neonates.
- Correlation of brain lesions with developmental abnormalities.
Main Results:
- Incidence of major neurodevelopmental handicaps has plateaued.
- Preterm infants with intraventricular hemorrhage are at increased risk.
- Neonates with cerebral infarction show higher rates of abnormalities.
- Cerebral blood flow alterations are implicated in both lesions.
Conclusions:
- Sophisticated perinatal care has not improved outcomes for neurodevelopmental handicaps.
- Intraventricular hemorrhage and cerebral infarction significantly elevate risks.
- Further research into managing cerebral blood flow is warranted.
Abstract:
The incidence of major neurodevelopmental handicaps in the survivors of newborn special care has remained essentially unchanged over the past decade despite the development of sophisticated perinatal care. Preterm infants with parenchymal involvement of intraventricular hemorrhage and neonates of all gestational ages with cerebral infarction are believed to be at higher risk for both neurologic and developmental abnormalities than infants without these problems. Both lesions are thought secondary to alterations in cerebral blood flow to the developing brain, and many infants demonstrate evidence for both hemorrhage and ischemic insult.
