What are neural tube defects?

What are neural tube defects?

NTD: Neural tube defects are a host of lesions that affect the spinal cord. They vary in degree from spina bifida occulta ( mildest ) to craniorrachischis totalis ( severest), spina bifida, and myelomengocele being the most frequently encountered. They have been linked to a diet deficient in folate (folic acid) during pregnancy. ...Read more

Neural Tube Defect (Definition)

Neural tube defects are birth defects of the brain, spine, or spinal cord. They happen in the first month of pregnancy, often before a woman even knows that she is pregnant. The most common neural tube defects are spina ...Read more

Are neural tube defect babies active?

Are neural tube defect babies active?

Possibly: It depends on multiple factors. There are different degrees of neural tube defects. Some people can have a mild defect and other may have a severe defect. It also depends on the location of the defect. Your doctor might be able to better answer this question with all of the relevant information. ...Read more

Is arnold chiari malformation type one a neural tube defect?

Is arnold chiari malformation type one a neural tube defect?

No: The more accepted term is chiari malformation as arnold-chiari is an older term. This type of malformation is not a neural tube defect, but rather an abnormal migration of the cerebellar tonsils below the level of the foramen magnum (chiari type 1). This defect is attributed to a congenitally small posterior fossa, thus allowing the cerebellar tonsils to migrate downward. ...Read more

How does folic acid prevent neural tube defects?

How does folic acid prevent neural tube defects?

NEURAL TUBE DEFECTS: Are one of the most common birth defects(1 in 1, 000 live births in this country). It is an opening in the spinal cord or brain that does not close properly. Folic acid and B12 help transport the necessary materials to make this happen normally. Folate (folic acid) is needed for production and maintenance of new cells, to make normal dna and rna. ...Read more

What is neural tube defects often mentioned in pregnancy..?

Spina Bifida: "neural tube defects" is a general name for developmental problems regarding the early developing spinal cord. The most commonly known defect is called "spina bifida" -- a defect in which the developing spinal cord is open to the skin on the back of the baby. This can lead to bowel or bladder control problems, neurologic problems, and even paralysis. ...Read more

Can there be meningocele in fetus without spina bifida?

Depends: This depends on how you define it. Meningoceles as they are commonly labeled originate anywhere from the neck down to the base of the spine and involve spina bifida. When a meningocele (bag of meninges) arises from the areas above the spine, it is more often labeled an encephalocoel because it usually has brain and meninges in it. ...Read more

Difference between fetal spina bifida and anencephaly?

Difference between fetal spina bifida and anencephaly?

Very different: Anencephaly is the abscence of a closed cranial cavity (head) and implies incomplete brain development/function. Essentially, anencephaly is being born without functioning brain. Spinal bifida is an incomplete closure of the neural tube. There is no implication of brain development or brain function. While there may be paralysis in spina bifida, the brain can function normally in many cases. ...Read more

Afp normal, enlarged brain ventricles, is it still possible to have a neural tube defect ntd?

AFP: A normal AFP reduces the risk of an open neural tube abnormality. Enlarged cerebral ventricles are usually not associated with neural tube abnormalities. ...Read more

What are the tests for neural tube defect?

What are the tests for neural tube defect?

Ultrasound, MSAFP.: Prenatal ultrasound should have >90% sensitivity for open neural tube defect detection around 20 weeks. Earlier (>16 weeks) risk stratification can occur with screening maternal blood for AFP - although that is not diagnostic and has to be followed by ultrasound for confirmation and/or differential diagnosis. Fetal MRI is used as part of evaluation for possible fetal surgery to treat spina bifida. ...Read more

What causes spina bifida? Is spina bifida caused by a spinal cord injury, or a chromosomal disorder?

What causes spina bifida? Is spina bifida caused by a spinal cord injury, or a chromosomal disorder?

Spina : Spina bifida is not an injury. It is a birth defect caused by failure of the nervous system to fully develop. When the embryo is forming, the nervous system starts out as a "neural tube" that is supposed to grow in a very specific way. If it does not, you are left with "neural tube defects" like spina bifida. There is nothing we know of that causes it for sure, but certain things make it more likely. It is more common with children that have trisomy 13, 18, or 21, but that is just an association, not a cause. They are very common, and the only thing we know of that might help prevent them is for the mother to take folate (folic acid). The hard part about that is the mother has to take folate (folic acid) very early in the pregnancy, often before she even knows she is pregnant. That is why the all women of child-bearing age are advised to take at least 0.4 mg of Folic Acid every day. ...Read more

What causes meningocele / spina bifida?

What causes meningocele / spina bifida?

Genetics usually: Altho there is high correlation with genetics causing meningocele / spina bifida, drugs (especially chemotherapeutics) and low blood folate (folic acid) during gestation or abdominal / pelvic irradiation during pregnancy are known causes. ...Read more

Is spina bifida caused by a spinal cord injury or chromosomal disorder?

Is spina bifida caused by a spinal cord injury or chromosomal disorder?

No one knows : There seems to be an interplay of genetic and environmental factors that cause this disease. Women who have had one child with spina bifida, or who are obese or diabetic have an increased chance of having a child with the problem. It is known that taking Folic Acid during the fertile years decreases the chance of having this problem. ...Read more

What defines a spina bifida as spina bifida occulta?

What defines a spina bifida as spina bifida occulta?

Skin covering: Spina bifida occulta, like open spina bifida, is a congenital malformation involving a problem with closing of the neural tube during development. However, there is not exposed neural tissue in spina bifida occulta. There can be tracts connecting the skin to the spinal cord, or lipomas or bands (tight filum) which can cause neurologic deficit. There can also be bony issues. ...Read more
