What Are The Core Symptoms Of Neural Tube Defects
None: There are no symptoms in a pregnant woman if her baby has a neural tube defect. The blood test for maternal serum Alpha fetoprotein (msafp) is frequently elevated, if she has that testing done, but an ultrasound is necessary to diagnose a neural tube defect in the baby. ...Read moreSee 1 more doctor answer
Neural tube defects is a birth defect in which a baby is born with some splitting of his spine and/or spinal cord structures. The problem can occur anywhere along the spine, but "spina bifida" at the bottom of the spine is the more common condition. Women take folic acid (a vitamin) before and during pregnancy to decrease the chances of their babies ...Read more
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 moreSee 1 more doctor answer
2 tests: To diagnose a neural tube defect the two most useful tests are 1) The mother's blood level of a protein that lines the inner surface of the developing spinal cord in the fetus, called alpha fetoprotein, and 2) a fetal or newborn ultrasound of the spinal canal itself. Other radiologic tests such as X-Ray films, CT scans, and MRI scans help to get a clearer picture of the neural tube defect ...Read more
NTD: The "best" test is an amniotic fluid AFP concentration. That picks up about 90% of open neural tube defects. However, an ultrasound examination also picks up the majority of open neural tube defects. ...Read more
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
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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
