Symptoms of neural tube defects

summary

Neural tube malformation, also known as neural tube defect, is a serious malformation disease. Neural tube is the central nervous system of fetus. From the 15th to 17th day of the embryo, the nervous system began to develop. About the 22nd day of the embryo, the two sides of the nerve fold began to close to each other, forming a tube, called the neural tube. Its front end was called the anterior foramen of the neural tube, and its tail end was called the posterior foramen of the neural tube. On the 24th, 25th and 26th day of the embryo, the anterior foramen and posterior foramen were closed one after another. Symptoms of neural tube defects? Let's talk about it

Symptoms of neural tube defects

The central nervous canal is the site where the embryo develops into brain, spinal cord, back of head and spine. If the central nervous canal does not develop normally, defects may appear in the above parts at birth.

Anencephaly and spina bifida are malformations that occur during fetal development. The so-called "neural tube malformation" refers to developmental malformations such as anencephaly, encephalocele, meningocele, spina bifida / recessive spina bifida, cleft lip and cleft palate.

Spina bifida refers to that the spine bone is not well developed, resulting in the protrusion or exposure of the spinal cord which should be protected by the spine bone. Spina bifida can be completely open, and the baby can be identified by naked eye as soon as it is born; It may also be recessive. With the increase of children's age, different symptoms are produced. At this time, X-ray diagnosis is needed. The most common defect is spina bifida, which can affect one or more segments of the spine. The symptoms of the disease include: leg weakness or paralysis, leg deformation, incontinence, no pain in the skin below the lesion level, sometimes hydrocephalus, and learning disabilities in some cases.

matters needing attention

1. For pregnant women with high risk factors, prenatal genetic counseling and necessary prenatal diagnosis should be strengthened to prevent the birth of severe congenital defects. 2. Supplement folic acid and vitamin B12, pregnant women in 1 month before pregnancy to 4 months after pregnancy, oral folic acid 0.4 mg once a day, can reduce the incidence of fetal neural tube defects by 70%, but not more, in order to prevent side effects. 3. Active and reasonable treatment of pregnancy diseases.
