Why do anencephaly occur, and if anencephaly, what are the characteristics?

All dharmas are born from the heart. All causes arise, and all causes perish.

Everyone knows that when a girl is pregnant, she actually needs to pay attention to many aspects, not only in her own dressing and travel. At the same time, it is necessary to do some prenatal check-ups regularly, so that some problems can be found in time and then solved in time. It will not cause much harm to the pregnant woman and the baby in the womb, but even this will not avoid some problems.

So you can often see the phenomenon of anencephaly on the news, so what we are going to talk about today is what are the characteristics of anencephaly?

Severe vomiting in pregnant mothers is first of all anencephaly, which can also be said to be one of the fetal malformations, then fetal malformations, that is, some abnormalities in some structures or chromosomes of the fetus in the mother's uterus. Then these abnormalities will lead to some serious deformities in the fetus, and will also lead to the death of the newborn baby. Then if you are pregnant with anencephaly, pregnant mothers will also have some symptoms.

The first is that pregnant mothers will vomit violently, because it is very normal to vomit during pregnancy. However, these vomiting are only mild vomiting, but if the pregnant mother has severe vomiting, it should be taken seriously.

Continuous high fever is followed by if the pregnant woman has a high fever, and the temperature of this high fever once reached more than Celsius. And when the fever lasts for a week or more than a week, it is necessary to take the pregnant woman to the hospital for a relative examination, because in this case, it is very likely that the child in the pregnant woman's womb is brainless. Only after the examination can the mother of the pregnant woman be relieved, and if this happens, it can be decided earlier.

The second genetic factor is that if I am so brainless, it can also be said to be a genetic disease. And when pregnant women are pregnant, they must think in advance about whether they have had anencephaly in their family genetic history, or they should ask whether their husband's family genetic history has been anencephaly. In this case, it should be considered carefully, especially before pregnancy, so as to avoid the appearance of anencephaly.

Anencephaly is a severe developmental defect of the central nervous system, with severe malformations of the brain and cranial vaults. The brain and cerebellum are reduced or absent, but anencephaly is present in the hindbrain as part of the neural tube defect (NTD) spectrum. When the neural tube does not close during the third to fourth week of development, it can lead to fetal loss, stillbirth, or neonatal death.

Anencephaly babies are characterized by polyhydramnios in the mother, a larger abdominal circumference during pregnancy than in the months of pregnancy, inability to touch the fetal head, unclear fetal position, and distant fetal heart sounds. And they can't survive after birth.

It may be due to congenital nutritional deficiencies, or it may be due to malformations, or it may be caused by polyhydramnios, some disorders in brain development, or there may be some problems with the facial nerves, all of which can cause him to have this condition.

It will be found that the child's reaction ability is relatively poor, basically the eyes are blank, and the head is relatively large, the facial features are relatively abnormal, the limbs are unable to move normally, and some characteristics that are obviously not normal people will be seen.

The symptoms of anencephaly are that they look like a frog's face, their neck is relatively short, they can't see the position of their neck, they don't have a brain, and they don't have any changes in their expressions.

Pregnant women will have polyhydramnios, an abdominal circumference larger than the gestational month, the position of the fetal head cannot be fetal, the fetal position is not clear, and the fetal heart sound is distant.

Pregnant women will vomit violently during pregnancy, and pregnant women will also be poisoned due to diabetes, and pregnant women will also have fever, even as high as 38 degrees or more, and if pregnant women have genetic diseases, they will also give birth to such children. Therefore, pregnant women must go to the hospital to see a doctor, must do some examinations in time, avoid giving birth to deformed children, and must be responsible for their own children. Pregnant women can also catch colds, and pregnant women usually work in front of electronic devices, are often exposed to radiation, and take some medicines that pregnant women cannot take when they are just pregnant, causing vomiting and diarrhea.

There will be miscarriages, and there will be certain obstacles in brain development, and the face will be unrefreshed, and it will also be stillborn.

This situation has not happened until now, and this is a very special thing, and it may also be because of the very imperfect development in the womb of the pregnant woman, which will lead to this brainless situation.

These children are likely to be stillborn, or they may be miscarried, or they will be underdeveloped or missing, and there will be abnormal fetal position, or there will be more amniotic fluid.

In general, there are no obvious symptoms, and it is necessary to be screened and confirmed, and it is not possible to confirm it by other means.

Most of the children are not intellectually adept, and there will be certain problems, and at the same time, intelligence will no longer grow, and they should go to the hospital in time.

Be sure to go to the hospital in time, listen to professional advice, and sometimes you need to consider giving up your child. It may also be done with medications**.

You should go to the hospital immediately for a check-up and then have an abortion to remove the baby.

Anencephaly is a malformation that occurs in the early stages of the fetus. Anencephaly is a malformation in which the top of the baby's head and skull are not well developed, and most of the brain is not well developed. Anencephaly often dies in the mother's womb before the malformation, and although a few survive at birth, they usually die within a few days, and there are no cases of survival.

Causes: Genetic factors: Genetic diseases are diseases that can be passed on to future generations, and are diseases caused by harmful changes in the person's genetic material, including genetic mutations, chromosome number and structural abnormalities, the most common diseases are trisomy 21 and trisomy 18.

Environmental factors: including biological factors, chemical factors, physical factors and drug factors.

Biological factors: It is one of the more important causes of birth defects, especially when the mother is infected by certain pathogens during pregnancy (including viruses, bacteria, parasites, etc.), these pathogens can infect the fetus through the placental villous barrier or the cervix, mainly torch pathogen group, what is the doctor talking about torch? They are Toxoplasma, Rubella Virus, Cytomegalovirus, Herpes Simplex Virus, in addition to chickenpox, herpes zoster virus, hepatitis virus and Treponema pallidum, among others.

Chemical factors: pesticides such as dichlorfon, trichlorfon, organochlorine, organic mercury, oxyoxyacid herbicides, dibromochlorohydrin, dichloride, lead, cadmium, mercury, manganese, aluminum and other heavy metals and vinyl chloride, chloroprene, acrylonitrile and other polymer compounds.

Physical factors: Physical factors refer to the meteorological conditions, radiation noise and vibration that exist in people's daily life and production labor. Teratogenesis is mainly caused by radiation, such as X-rays and various other rays. Radiation can cause chromosomal aberrations that can cause malformations in the fetus.

Drug factors: Most antineoplastic drugs are toxic, and embryonic cells are more sensitive to antineoplastic drugs than mature and differentiated cells, so most of these drugs cause greater damage to the embryo at lower doses. Antibiotics such as streptomycin, kanamycin, most anti-tuberculosis drugs, hormones, and live vaccines are teratogenic when used in the first trimester, that is, during the teratogenic sensitive period.

Others: such as smoking, alcohol, the risk of fetal malformations after drinking a lot of alcohol is very high, which is characterized by developmental retardation, microcephaly, multiple small malformations, etc., smoking can cause miscarriage, premature birth, congenital heart disease and low birth weight of newborns.

There are also brain cell necrosis caused by severe hypoxia in the production process, which is also a kind of anencephaly! The precapsule of the head is sunken, unresponsive, and the gaze is glazed!

It is related to genetics, environment, food, drugs, maternal and child blood group incompatibility, etc.

1. 无encephal (wú nǎo): anencephaly is a malformation that exists in humans and various vertebrates, in which the neural plates of the brain remain in an open state without atresia, and the formation of brain tissue is severely inhibited, often accompanied by cleft palate and partial absence of spinal cord. This malformation can be caused by the lack of oxygen in the embryogenesis of amphibians and chickens.

2. Brainless is often used to describe stupid people, which basically means to describe people who do things without going through the brain, and behave very stupidly.

Disease analysis: Hello, the survival rate of anencephaly children is low, the brain plays a coordinating role in the whole body organ system, anencephaly children will inevitably have dementia, will inevitably lose their ability to exercise and live, and the severity of the symptoms is related to the condition of normal brain tissue.

Suggestions: Suggestion: If the ultrasound shows that the fetus is anencephaly, the reexamination should be considered, and the reexamination results still indicate that the anencephaly should be considered as soon as possible.

No brains, do things without thinking.

There is no thought, and life depends on instinct.

My understanding is: there is no idea of your own.

Don't use your brain, it's like you don't have a brain.
