Summary
Prenatal risk factors for cerebral palsy (CP) are more diverse than previously thought. Advances in science reveal numerous causes of neonatal encephalopathy beyond delivery complications, impacting fetal development.
Area of Science:
- Neurology
- Genetics
- Obstetrics
Context:
- Cerebral palsy (CP) is increasingly understood to originate from diverse prenatal factors, challenging the historical focus on perinatal delivery complications.
- Scientific and clinical advancements, including fetal neuroimaging and genetic analysis, have expanded the identification of etiologies for neonatal encephalopathy.
Purpose:
- To review the expanded list of prenatal risk factors contributing to cerebral palsy (CP).
- To highlight the shift in understanding CP etiology from delivery-related events to a broader spectrum of prenatal influences.
Summary:
- Prenatal factors, including genetic causes, maternal infections, metabolic errors (e.g., diabetes), and substance exposure, are significant contributors to CP.
- Asphyxia accounts for a small percentage of CP in full-term infants (6-10%), while periventricular leukomalacia is linked to 30-50% of CP in premature births.
- The article also touches upon CP risks in multiple births where other fetuses may have died in utero.
Impact:
- This review broadens the understanding of CP's origins, emphasizing the critical role of prenatal factors in fetal brain development.
- It informs clinical practice and research by highlighting the multiplicity of causes, enabling more targeted diagnostic and therapeutic strategies for cerebral palsy.
