How do you know if your baby has a neural tube defect before birth?

How do you know if your baby has a neural tube defect before birth?

MSAFP and ultrasound: Maternal serum Alpha fetoprotein at 16 weeks and detailed ultrasound at 18-20 weeks should detect fetal open neural tube defects with 96% accuracy. Closed neural tube defects are more difficult to diagnose but are more innocuous too. ...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

Can you tell me how is neural tube defect diagnosed after birth (not prenatally)?

Can you tell me how is neural tube defect diagnosed after birth (not prenatally)?

Physical exam: NTD's can form from one end of the nervous system to the other. The most common is spina bifida cystica with a sac of the inferior spinal cord and a skin opening near the lower end of the spine.Hidden defects in the area may be suspected on close exam. NTD at the neck can have a sac of neural tube coverings, Anencephaly, with an open skull is also obvious. ...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

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

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

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

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 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

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 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 more

Is it a neural tube defect if your sacral dimple is bottomless?

Is it a neural tube defect if your sacral dimple is bottomless?

Depends: If the dimple is deep and not skin covered at the deepest level than spina bidida or other defects may be present. Imaging studies such as ultrasound or spine films may be required. ...Read more

Are there effective natural treatments for neural tube defects?

No: There are no natural treatments for neural tube defects. The presence of a neural tube defect in a fetus requires surgical closure either in utero or after delivery. Closure of the defect can be associated with accumulation of fluid in the brain and shunting is sometimes necessary. ...Read more

If a sacral dimple is closed and is just a skin dimple, does this mean the child has a neural tube defect underneath?

If a sacral dimple is closed and is just a skin dimple, does this mean the child has a neural tube defect underneath?

Sacral dimple: Most of the time, sacral dimples are harmless and don't require any treatment. Rarely, a sacral dimple may indicate a serious underlying abnormality of the spine or spinal cord. To rule out any abnormality, your child's doctor may recommend an imaging test. If an abnormality is discovered, treatment depends on the underlying cause. ...Read more

I tested positive for neural tube defect (I'm 20 weeks). I had my level 2 ultrasound and everything is normal. Should I still be worried?

I tested positive for neural tube defect (I'm 20 weeks). I had my level 2 ultrasound and everything is normal. Should I still be worried?

Yes: Vigilant is a better term. All tests have a certain propensity for false positive and false negative results. While the ultrasound is reassuring, don't let it bring down your guard. Remember to communicate the findings with staff at the hospital/delivery environment as well as to the NICU/well-baby staff as relevant. A focused post-partum physical exam (baby) is important. ...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 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

I want to know what's the neural tube defect test?

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

What is the definition or description of: Neural tube defect?

Neural tube defect: 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 bifida, anencephaly, and encephalocele. ...Read more

Today I found out that I had a high risk for open neural tube defect/ what do I do next ?

How did you find out: Are you pregnant. or was it from reviewing your family history? Before pregnancy, the risk of an NTD can be reduced to the general population risk by taking 4 mg of folic acid daily before you know that you are pregnant. NTDs occur before a woman knows that she is pregnant,so starting folate then is shutting the barn door after the horse is gone. If pregnant, you require appropriate diagnostics ...Read more
