This disorder is a neural tube defect and involves incomplete development of the brain, spinal cord, and/or their protective coverings.
There is good evidence now that women who have had a baby with anencephaly or spina bifida should take higher dose folic acid in subsequent pregnancies and that this considerably reduces the risk of a second baby being affected.
anencephaly -- a type of neural tube disorder where the baby's brain does not form. This is caused by a failure of the neural tube to close properly very early in the baby's development.
Anencephaly: A neural tube defect involving severe structural defects of the brain and skull. Fetuses with anencephaly do not survive.
Anesthesia: Loss of sensation, or general insensibility to pain, induced by an anesthetic.
Anencephaly: Defective development of the brain combined with the absence of the bones normally surrounding the brain.
Angioma: Tumor, usually benign, or swelling composed of lymph and blood vessels.
Anencephaly - A birth defect resulting in the abnormal development of the baby's brain and skull.
Anesthesia - A partial or complete loss of sensation or consciousness, with absence of pain sensation, produced by an anesthetic ...
Anencephaly: This is the most severe form of Spina Bifida and affected babies have a high mortality rate. Still birth or death shortly after birth is the expected outcome. This is because anencephaly is the result of minimal brain development.
Anencephaly: A neural-tube defect wherein the baby’s skull and brain do inside the uterus. The baby usually remains alive while growing inside the uterus, but dies soon after birth.
Anencephaly: A severe congenital defect in which the fetus has no brain.
Anesthesia: Medically induced loss of sensation. General anesthesia involves the entire body; local anesthesia involves only a particular area.
A birth defect resulting in the absence of a major portion of the skull and brain. Anencephaly results when the upper portion of the neural tube fails to close.
Anencephaly - Defect resulting in the absence of most of the brain and spinal cord.
Anesthesia - A medication that causes unconsciousness or a loss of general sensation.
Anencephaly: A rare birth defect in which the baby has a malformed skull and little or no brain.
Anencephaly. A defect in which the neural tube fails to close. The neural tube is a narrow channel that normally closes about the fourth week of pregnancy to form the brain and spinal cord.
One of several neural tube defects. The neural tube is a embryonic structure in the developing fetus that forms the spinal cord and brain.
Anencephaly and spina bifida are the two most common NTDs. Anencephaly is a fatal condition in which the upper end of the neural tube fails to close. In these cases, the brain fails to develop completely or is entirely absent.
Anencephaly and spina bifida are the most common types of ONTD, while encephalocele (in which there is a protrusion of the brain or its coverings through the skull) is much rarer.

Anencephaly - A neural tube defect in which the the head end of the neural tube does not close. Normally, the neural tube will fold and close during the 3rd to 4th week of pregnancy.
We had a history of anencephaly in our family, and had had the AFP test with Hilary. SInce it came back saying that everything was fine, we didn't even question wether or notto do it again.

You reduce your chances of giving birth to a baby with a neural tube defect (for example, anencephaly or spina bifida) by 50% to 70% if you start taking at least 0.4 mg of folic acid each day two to three months before you start trying to conceive.
Two common tubal defects are: Spina bifida, which results when the column surrounding the spinal cord is not formed, and anencephaly, which occurs when the brain is not completely formed.
Alpha fetoprotein: a protein produced by the baby that can be measured prenatally, by taking a tube of your blood, to identify possible neural tube disorders and other potential problems, such as Down's Syndrome or anencephaly.
For example, one child could be born with anencephaly, while the second child could have spina bifida and not anencephaly.
The neural tube closes 28 to 32 days after conception, before many women are aware they are pregnant.

The technical names of the two major neural tube birth defects reduced by adequate folate intake are anencephaly and spina bifida. Babies with anencephaly do not develop a brain and are stillborn or die shortly after birth.
Other Neural tube defects can be hydrocephalus(water on the brain) and anencephaly which is a cephalic disorder that results when the cephalic (head) end of the neural tube fails to close, usually between the 23rd and 26th day of pregnancy, ...
There are two main birth defects that folic acid helps to prevent: Spina bifida and anencephaly. Spina bifida is a condition in which the spinal cord doesn't fully develop; it results in permanent disability.
Folic acid deficiency is linked to such neurologic birth defects as spina bifida and anencephaly.
Other forms of birth defect, such as anencephaly, which is a serious incomplete development of the brain, and encephalocele, which is when brain tissue abnormally protrudes through an opening in the skin, ...
MSS can detect babies at higher risk of Down's syndrome and the neural tube defects - NTDs - anencephaly, where the brain is very underdeveloped, and spina bifida, where the spinal cord coverings are incomplete and the lower body may be paralysed.
It can detect such problems as spina bifida, anencephaly and possibly Down's Syndrome. If the test comes back as abnormal, you can have it confirmed with another AFP test or it's possible your provide may recommend you have amniocentesis.
Using a combination of MSAFP screening and ultrasonography, almost all cases of anencephaly can be found and most cases of spina bifida.

open neural tube defects (ONTDs) - defects in the primitive spine, called the neural tube, such as spina bifida (open spine) and anencephaly (open skull).
"p" arm - the top half, or shorter arm of a chromosome.
If the neural tube does not close at the top, the baby will have anencephaly (without a brain). If the neural tube does not close at the bottom, the baby will have spina bifida.
While researchers don't know why folic acid helps prevent birth defects, it has been shown to decrease the risk of the most common NTDs: spina bifida (the leading cause of childhood paralysis) and anencephaly (a fatal condition in which an infant is ...
Also, without enough folic acid, your baby's brain may not form or may only partly form -- a condition called anencephaly. All of these defects occur during the first 28 days of pregnancy -- usually before a woman even knows she's pregnant.
Elevated MSAFP correlates with different fetal anomalies such as neural tube defects (anencephaly and spina bifida) and abdominal wall defects, as well as with fetal death, multiple gestations, and certain abnormalities of the placenta.
Low folate levels have been linked to serious birth defects, especially anencephaly and spina bifida. Good sources of folate: dark-green leafy vegetables, dry beans, peas, fortified cereal and whole-grain products.
It can also pick up several hundred other genetic disorders, such as cystic fibrosis, sickle cell disease, and Tay-Sachs disease, as well as neural tube defects (such as spina bifida and anencephaly).
Women who ate the healthiest were 55% less likely to have a baby with anencephaly, 28% less likely to have a baby with spina bifida and 36% less likely to have a baby with a cleft lip, as compared to women with the worst diets.
Folic acid is instrumental in preventing neural tube defects (NTDs) - serious birth defects of the spinal cord (such as spina bifida) and the brain (such as anencephaly)." This article gives the facts and details on folic acid during pregnancy.
the March of Dimes found that overweight and obese women were reported to be 30 to 40 percent more likely than healthy-weight women to deliver a baby with a major birth defect, in particular a neural tube defect, which affects the brain (anencephaly) ...
for 4 biochemical markers, (AFP, HCG, estriol, DIA), has a detection rate of 75% - 80% for aneuploidy. It will also detect 80% of open neural tube defects, which is incomplete closure of the fetal spine that can cause spina bifida or anencephaly.
It is ordered to help evaluate the risk that a fetus has certain abnormalities, including Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), and neural tube defects such as spina bifida or a condition called anencephaly.
