Cerebral palsy can be detected by a labor and delivery test before birth, but cerebral palsy caused by fetal nerve damage during delivery cannot be detected by a labor and delivery test. Cerebral palsy is a movement disorder that occurs in newborns and is often caused by lack of oxygen in the womb before birth or nerve damage during birth, making it a more serious brain problem. The risk of cerebral palsy is increased by prenatal infections in the uterine cavity, intrauterine distress caused by structural abnormalities of the placenta and umbilical cord or by umbilical cord wrapping around the neck, and abnormalities of craniocephalic development such as hydrocephalus, and can be detected early in some cases through close prenatal checkups. However, more children with cerebral palsy develop cerebral palsy as a result of neurological damage to the brain due to obstructed labor, intrauterine hypoxia, amniotic fluid embolism, umbilical cord entrapment, or placental abruption or placenta previa, which cannot be predicted or detected by prenatal checkups.
