In general, amniocentesis cannot screen for cerebral palsy. Amniocentesis is a procedure in which a puncture needle is passed through the belly and uterine wall of a pregnant woman one by one under ultrasound guidance to enter the amniotic cavity and extract a small amount of amniotic fluid, which is subsequently examined for fetal chromosomes and DNA. The main purpose of the amniocentesis test is to clarify whether there is any chromosomal abnormality in the fetus. The symptoms of cerebral palsy are more 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 chromosomal abnormalities are detected by amniocentesis, there is no way to determine whether the fetus has cerebral palsy. Although it is difficult to diagnose cerebral palsy during the fetal period, there are some problems that can be detected through examination, which suggests that the fetus may have a combination of cerebral palsy. In addition to the chromosomal abnormality mentioned above, the enlarged lateral ventricles and obvious hydrocephalus detected by abdominal ultrasound also suggest abnormalities in the functioning of the fetal nervous system, which may lead to cerebral palsy after birth. Pregnant women are advised to consult their doctors to make a reasonable decision, and terminate the pregnancy early if necessary. In order to prevent fetal cerebral palsy, pregnant women should increase their nutrition, and are advised to consume foods rich in high quality protein and vitamins as well as high calcium content. In addition, pregnant women should avoid external stimuli, such as radiation and toxic substances, which may cause abnormal brain development and cerebral palsy in the fetus.
