Is spina bifida hereditary?

Is spina bifida hereditary?

Studies show that : the incidence of neural tube defects (NTD's) like open Spina Bifida would decrease by 70% if all women took 0.4mg of Folic Acid daily from menarche to menopause. However, this dose does not prevent NTD's in offspring of women with variations in several genes involved in folate (folic acid) & homocysteine metabolism. There are also inheritable genetic causes of NTD's that are not related to folate (folic acid) metabolism. ...Read more

Spina Bifida (Definition)

A birth defect involving incomplete development of the spinal cord or its coverings. The exact cause of the condition is unknown, but a risk factor appears to be low levels of folic acid in a woman's body before ...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

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

Who discovered spina bifida?

Although depictions : of people with Spina Bifida go back 12,000 years, Amsterdam's Dr. Nicholas Tulp named the disorder between 1618-1652. Dr. Giovanni Battista Morgagni an Italian, linked lower-limb deformity & hydrocephalus to Spina Bifida in 1761. Studies show that the incidence of NTD's could decrease by as much as 70% if all women were to take a daily Folic Acid supplement from menarche to menopause. ...Read more

What is spina bifida?

Spinal cord disorder: The spinal cord forms as an open tube that starts to close from the middle out to the two ends. The entire closure is done by about ten weeks. If the closure is not normal than a condition known as spina bifida occurs. Open spina bifida is when there is an opening in the spinal column to the skin. Closed spina bifida is when there is an opening in the spinal column but it has a thin cover. ...Read more

Later side afects of low spina bifida occulta? Incontinence?

Possible: Spina bifida and occulta an be associated with urinary dysfunction. Incontinence and/or urinary retention can occur. Recommend further evaluation with urologist, urogynecologist or neuro-urologist. Additional testing can clarify causes such as urodynamic testing. ...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

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

Later side afects of occult spina bifida?

Later side afects of occult spina bifida?

No: Spina bifida occulta results from failure of the two lamina of one vertebra to make a solid bony fusion. The defect is generally bisecting the spinous process vertically. No instability is present. No neurologic dysfunction is present because neural elements are not affected. But associated neurological problems which may be symptomatic are more common in association with spina bifida occulta. ...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

Are congenital heart defects hereditary?

Are congenital heart defects hereditary?

Depends on variables: There are a few syndromes with high frequency of specific heart defects that can have inheritance risk up to 50%. Most, however, are part of a complex inheritance pattern with around 5% risk.This 5% would include any pattern of congenital heart defect, not necessarily the same one. ...Read more

Old mom. Is closed spina bifida deformity a risk to offspring?

Old mom. Is closed spina bifida deformity a risk to offspring?

Is it simple?: Spina bifida includes a spectrum of anatomical problems ranging from the most severe (but fortunately rarest) called myelomeningocele wherein the coverings of the spinal nerve sac (dura & arachnoid) are absent allowing nerve roots to herniate sometimes through bony & skin defects to the outside world. Spina bifida occulta is most common & most benign-failure of 2 bones (lamina) to completely unite. ...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

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

Why do spina bifida patients have a myelomeningocele repair later?

Why do spina bifida patients have a myelomeningocele repair later?

Myelomeningocele: Usually the repair of a myelomeningocele is delayed several days after birth to ensure that the child is stable for surgery and to also get a better assessment of potential neurologic deficits. As an adult, some patients develop spinal cord symptoms from tethering of the spinal cord prompting a procedure to release the tension on the spinal cord. ...Read more

What's the difference between spinal bifida and spinal bifida occulta?

What's the difference between spinal bifida and spinal bifida occulta?

Type of spina bifida: The mildest form of spina bifida is spina bifida occulta and is a small separation or gap in one or more of the vertebral bones of the spine. Most people with spina bifida occulta have no signs or symptoms because their spinal nerves are undamaged. Signs sometimes occur in the skin on top of the spinal defect, such as a clump of hair, a dimple, a birthmark, or a lump of fat. ...Read more
