Will become abnormal pain, require the baby to keep enough attention to accept the treatment of this disease, neural tube malformation, is due to in the embryonic period, affected by genetic and environmental factors, resulting in incomplete neural tube closure, thus forming anencephaly, spina bifida and so on.

What symptom does pregnant have brainless child

First, medical research has known that there are more than 600 kinds of chemical substances that can enter the fetal body through the placental barrier of pregnant women. They can lead to the failure of implantation of fertilized eggs, delayed embryonic development, or chromosome mutation or gene mutation, which may lead to abortion, stillbirth, and more importantly, incomplete embryonic development.

Second: although mental and emotional factors have an impact on pregnant women and fetuses, they do not directly affect the development of embryonic nervous system and are not the direct causes of anencephaly.

Third: pregnant women emotional fluctuations, or during pregnancy and others quarrel, will not produce anencephaly. There is no scientific basis for the theory of "watching monkeys play tricks" and "watching people build new houses".

matters needing attention

1. Folic acid should be supplemented 3 months before pregnancy and 3 months in advance. During pregnancy, the folic acid content in the body will reach an ideal level, and it should be taken all the time until 3 months after pregnancy, so as to ensure the development needs of the baby. 2. Men should also supplement folic acid. Women should not only supplement folic acid, but also men. This is because folic acid can help the synthesis of DNA. If men lack folic acid, it will increase the risk of chromosomal defects in their babies. 3. Pay attention to the dosage of folic acid. The best dosage to prevent neural tube defects is 400 micrograms per day, one tablet per day. 4. Folic acid is widely distributed in animal and plant foods. Foods rich in folic acid include green vegetables, fresh fruits, animal liver and kidney, eggs, beans, nuts and grains. However, in the food intake of folic acid, we need to pay attention to: because folic acid is a water-soluble vitamin, unstable to heat and light, easy to lose activity, which requires you to change some cooking habits in daily life, try not to put the food too long, as far as possible to reduce the loss of folic acid.
