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

Pregnancy (Definition)

When your due date arrives, you will be more than ready to have your baby! Most women deliver the baby somewhere between 37 and 42 weeks. According to the American College of Obstetricians and Gynecologists, only 5% of babies arrive on the exact due date. Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...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

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

Is there a relationship between cranioschisis and neural tube defects (ntds)?

Related conditions: Open neural tube defects affect areas from the head to end of spine. Usually referred to a Spina Bifida lower on down the vertebral column. The central nervous system needs to close early in gestation before birth. "Schisis" means open or failure to close. Carino's hiatus is a very severe condition. Consult w a pediatric neurologist is recommended ...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 are the tests for neural tube defects?

Antepartum Dx.: There are screening tests available to detect neural tube defects in the fetus. The most common is called alfa fetoprotein. The levels of this substance is significantly increased if the fetus is affected with an open neural tube defect. ...Read more

Can genetic testing prevent birth defects in pregnancy?

Can genetic testing prevent birth defects in pregnancy?

Nope.: Genetic prenatal testing can detect many chromosomal or microscopic dna defects - but it cannot prevent birth defects! 2-4% of all newborns will have a minor or major birth defect and the vast majority of those have unknown genetic underpinnings at this time, although many of us are working to change that. Take Folic Acid 1-5 mg daily to prevent 75-95% of major neural/cardiac fetal anomalies! ...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

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

Do amniotic sac disorders cause birth defects?

Do amniotic sac disorders cause birth defects?

Amniotic Fluid: Best discussed with your ob. Too much or too little amniotic fluid is associated with abnormalities in development and pregnancy complications. Differences in the amount of fluid may be the cause or the result of the problem. ...Read more

What is the best neural tube defect test?

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

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

Can rubella in early pregnancy cause baby to have spina bifida ?

Can rubella in early pregnancy cause baby to have spina bifida ?

Unlikely : The neural tube defects are considered a random event and are present by ~ 28 days into the pregnancy. Rubella that occurs this early in pregnancy would more likely cause fetal loss, although a heart and eye defects would also be possible. ...Read more

Can you tell me about the relationship between cranioschisis and neural tube defects (ntds)?

Dr. Suhas Pai Dr. Pai
2 doctors agreed:

Same thing: Cranioschisis is simply a type of neural tube defect. Cranioschisis refers to when the cranial end of the neural tube does not close and the skull and brain do not form properly as a result. There are other types of neural tube defects which affect the development of the spinal cord instead of the brain. Spina bifida is an example. ...Read more

Can folic acid prevent Lamotrigine causing all birth defects during pregnancy?

Can folic acid prevent Lamotrigine causing all birth defects during pregnancy?

Any drug causing: birth defects is separate from taking a supplement to support neurological development in pregnancy. Most supplements don't and aren't designed to prevent against birth defects. If you are concerned about this, discuss it with your OB/GYN doctor, and get a full evaluation of what you're taking, and what your concerns are. So, you can have piece of mind. Taking too much folic acid is not wise too. ...Read more

What can block fallopian tubes after child birth?

What can block fallopian tubes after child birth?

Many Causes: Some times an infection develops that can block the tubes. If a woman has a cesarean delivery, sometimes scar tissues develops that blocks the tubes. It is also possible that the tubes were damaged or infection before delivery and over time the damage just got worse and eventually caused the tubes to be blocked. ...Read more

Are congenital defects the same as birth defects?

Are congenital defects the same as birth defects?

Yes: Here is a primer on the terms congenital refers to being present at birth. Anomalies, abnormalities, defects are often used interchangeably. Not all are genetic or familial. Malformation and deformation mean different things. Malformation is an anomaly due to abnormal formation of a structure. Deformation is a change in a structure due to forces like pressure, eg, in cases of low amniotic fluid. ...Read more
