In general, amniocentesis does not screen for cerebral palsy. Amniocentesis is a procedure in which a puncture needle is passed through the belly and uterine wall of the pregnant woman one by one under ultrasound guidance to enter the amniotic fluid cavity, extract a small amount of amniotic fluid, and subsequently check the chromosomes and DNA of the fetus in it. The main purpose of amniocentesis is to determine whether the fetus has any chromosomal abnormalities. The symptoms of cerebral palsy are insidious and difficult to detect during the fetal period, and need to be determined after birth based on the condition of the newborn. Chromosomal abnormalities do not always lead to cerebral palsy. Therefore, even if a fetal chromosomal abnormality is detected by amniocentesis, it is not certain that the fetus has cerebral palsy. Although it is difficult to diagnose cerebral palsy during the fetal period, there are some problems found through the examination that suggest the fetus may be combined with cerebral palsy. In addition to the chromosomal abnormalities mentioned above, the finding of enlarged lateral ventricles and significant hydrocephalus through abdominal ultrasound also indicates abnormal fetal nervous system function, which may lead to cerebral palsy after birth. It is recommended that pregnant women make a reasonable decision after consulting a doctor and, if necessary, terminate the pregnancy early. In order to prevent fetal cerebral palsy, pregnant women should increase nutrition, and it is recommended to eat foods rich in high quality protein and vitamins and high in calcium. In addition, pregnant women should avoid external stimuli, such as radiation and toxic substances, which can easily cause abnormal fetal brain development and cerebral palsy.
