The causes of cerebral palsy are complex. Any cause of fetal and pediatric brain tissue ischemia, hypoxia, injury or poisoning can cause brain damage, which can lead to cerebral palsy. The common causes are summarized as follows: (1) Before delivery: Advanced pregnancy, habitual abortion, multiple births, huge babies, viral infection in the third trimester, long-term medication, intrauterine infection, pre-eclampsia, maternal poisoning, maternal exposure to X-rays, abnormalities of the placenta and umbilical cord, prenatal hemorrhage, immature fetuses, and multiple pregnancies. (2) During labor: long labor, premature water breakage, placental dysfunction, abnormal amniotic fluid, abnormal umbilical cord, umbilical cord wrapping around the neck, intrauterine hypoxia, cesarean section, fetal head suction assisted delivery resulting in cranio-cerebral trauma, or cerebral tissue hemorrhage through obstructed labor. Neonatal hypoxic-ischemic encephalopathy secondary to severe asphyxia. (3) After delivery: asphyxia, hemorrhagic jaundice, neonatal shock, intracranial injury, encephalitis, meningitis, pneumonia, and encephalopathy caused by various infections. This refers to certain diseases that damage brain tissue within the first month after birth. (4) Other: family factors: congenital genetic diseases in family members or immediate relatives, such as degenerative diseases, mental disorders, mental retardation, familial congenital malformations.
