Got my wife.S test done. Neural tube defects came positive. Radiologist said that spine and head r fine. Now my daughter is 15 days old. Any worries?

Neural tube: If there was a neural tube defect it would have been seen at the time of birth. At 15 days of age if nothing is present on examination then likely the original testing was not entirely accurate which can happen. ...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

Afp normal, enlarged brain ventricles, could it be a neural tube defect?

Afp normal, enlarged brain ventricles, could it be a neural tube defect?

Neural tube defect: If AFP is normal there is likely not a neural defect, but the test is not 100% positive. ...Read more

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

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

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

What is the chance of having another child with a neural tube defect?

8x greater risk: It has been shown that having a child with a neural tube defect increases the chance of having a second child with a similar defect. The recurrence risk in this situation is 8 times greater than the risk if no such history was present. Also if there is any family history of neural tube defects there is an increased risk of an affected pregnancy even if not immediate relative (2cd or 3d degree). ...Read more

I have a high positive for increased open neural tube defect, now what?

Additional screening: A positive initial screening test should be followed by a more involved and dependable test looking for this possibility.A diagnostic high resolution ultrasound can be performed that can evaluate baby from top to bottom and see if there is any direct evidence of a problem. Discussion of these findings with a geneticist or perinatologist may then be needed if the problem is not excluded by the test. ...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

Which is the chance of having more then one child with a neural tube defect?

Which is the chance of having more then one child with a neural tube defect?

NT defect: This depends on the cause of the defect, but overall, your risk for a second child with a neural defect increases after you have a child with a defect. Your OB will likely suggest taking a higher dose of folic acid when you are thinking of conceiving. ...Read more

What kind of likelihood is there of having more then one child with a neural tube defect?

It varies: If parents have had one child with a neural tube defect their risk of having another child with a defect is about 3 %. If they have had two children with the defect their risk increases to about 7 %. A parent who has a neural tube defect also has about a 3 % risk of having a child with a neural tube defect. All of these risks can be lowered significantly by maternal Folic Acid ingestion. ...Read more
