Is neonatal infection linked to cerebral palsy?

Is neonatal infection linked to cerebral palsy? Yes, infections in newborns or during pregnancy can harm the developing brain and raise the risk of cerebral palsy, a condition that affects movement and muscle control.

Cerebral palsy often starts from brain damage early in life. One key trigger is neonatal infection, which means infections in babies right after birth. These can inflame the brain or cut off oxygen, leading to lasting harm. For example, meningitis attacks the membranes around the brain and spinal cord. It spreads from nearby infected spots or through the blood. Group B streptococcus and E coli bacteria are common causes in newborns. If doctors miss or fail to treat these, the infection can cause brain injury and cerebral palsy.

Infections during pregnancy also play a role. Maternal infections like chorioamnionitis infect the amniotic fluid and uterus. Bacteria travel from the vagina or across the placenta. This can pass to the baby, sparking brain swelling or sepsis, a body-wide inflammation. Other risks include cytomegalovirus, herpes, HIV, German measles, chickenpox, toxoplasmosis, and syphilis. These can trigger encephalitis, which inflames the brain itself, or jaundice from high bilirubin levels. Even high fevers from flu in early infancy might lead to movement problems like cerebral palsy later.

Post-birth infections matter too. Meningitis directly hits the brain with germs. Neonatal sepsis after delivery ups the odds, especially in premature babies with low birth weight. Studies link these to white matter damage seen on MRI scans, a common cerebral palsy sign.

Not every infection causes cerebral palsy. Factors like genetics or asphyxia can combine with infections. Early treatment of infections lowers the risk. Quick diagnosis helps babies get care to limit brain damage.
