Causes & Risk Factors
Several factors can contribute to Spina Bifida.
Causes
Spina bifida occurs during the earliest stages of pregnancy, often before a woman even knows she's pregnant. Between the third and fourth week after conception, the neural tube that will become the baby's brain and spinal cord should close completely. When this process doesn't happen properly, spina bifida results. Scientists don't know exactly why this closure fails in some pregnancies, but they've identified several contributing factors. The most significant factor is inadequate folic acid during early pregnancy. Folic acid, a B vitamin, plays a crucial role in neural tube development. When mothers don't get enough folic acid before conception and during the first trimester, the risk increases substantially. This is why doctors recommend folic acid supplements for all women of childbearing age. Genetic factors also play a role, though no single gene causes spina bifida. Families with one affected child have a slightly higher chance of having another child with the condition. Environmental factors, certain medications, and maternal health conditions like diabetes can also increase the risk. Some research suggests that elevated body temperature during early pregnancy, whether from fever or hot tub use, might contribute to neural tube defects.
Risk Factors
- Inadequate folic acid intake before and during early pregnancy
- Previous pregnancy affected by neural tube defect
- Family history of spina bifida or neural tube defects
- Maternal diabetes (Type 1 or Type 2)
- Maternal obesity before pregnancy
- Taking certain anti-seizure medications during pregnancy
- Elevated body temperature in early pregnancy
- Hispanic ethnicity (slightly higher prevalence)
- Maternal age over 35 years

Diagnostic Process
Doctors can often detect spina bifida before birth using routine prenatal screening tests. Between 15 and 20 weeks of pregnancy, a blood test called the maternal serum alpha-fetoprotein (MSAFP) can reveal elevated levels of a protein that suggests a neural tube defect. If this screening suggests a problem, doctors typically recommend more detailed testing, including a specialized ultrasound and possibly amniocentesis, where a small sample of amniotic fluid is tested for genetic abnormalities. Ultrasound imaging has become increasingly sophisticated and can usually provide a clear picture of the spine and any openings. During these detailed scans, doctors can determine the type and severity of spina bifida, which helps families prepare for their baby's needs. Some specialized centers even offer fetal surgery to repair certain types of spina bifida before birth, though this remains a complex procedure with specific criteria. If spina bifida isn't detected before birth, it becomes obvious immediately after delivery. Doctors will thoroughly examine the baby's back and perform neurological tests to assess movement and sensation. Additional tests like MRI or CT scans help determine the extent of spinal cord involvement and check for hydrocephalus, which occurs in about 80% of children with the most severe form of spina bifida.
Complications
- People with spina bifida may face various complications throughout their lives, though many can be successfully managed with proper medical care.
- Hydrocephalus affects about 80% of those with myelomeningocele, the most severe form, and requires lifelong monitoring of shunt function to prevent dangerous increases in brain pressure.
- Kidney and urinary tract problems develop frequently due to neurogenic bladder, potentially leading to infections, kidney stones, or kidney damage if not properly managed through regular catheterization and medical monitoring.
- Mobility challenges vary widely depending on the level and severity of the spinal defect.
- Some people walk independently, others use braces or crutches, and some rely on wheelchairs for mobility.
- Skin problems can develop due to decreased sensation, making regular skin checks and pressure relief important to prevent dangerous sores.
- Learning difficulties affect many children with spina bifida, particularly in areas like attention, executive function, and mathematical concepts, though most attend regular schools with appropriate support.
- Latex allergies develop in up to 75% of people with spina bifida, likely due to repeated exposure to latex products during medical procedures, requiring careful avoidance of latex-containing items.
- Despite these potential complications, many people with spina bifida lead fulfilling lives, attend college, pursue careers, and start families of their own.
Prevention
- The most effective way to prevent spina bifida involves ensuring adequate folic acid intake before conception and during early pregnancy.
- All women of childbearing age should take 400 micrograms of folic acid daily, even if they're not planning to become pregnant, since neural tube development occurs so early that many women don't yet know they're pregnant.
- Women with a higher risk, such as those who've had a previous pregnancy affected by spina bifida or take certain medications, need higher doses of 4,000 micrograms daily under medical supervision.
- Many foods are now fortified with folic acid, including cereals, breads, and pasta, but supplements ensure adequate intake.
- Natural food sources of folate include leafy green vegetables, citrus fruits, beans, and fortified grains, though these alone may not provide sufficient amounts for prevention.
- Women planning pregnancy should also maintain a healthy weight, manage diabetes effectively if present, and avoid medications that might interfere with neural tube development.
- Some anti-seizure medications increase the risk, but women shouldn't stop taking necessary medications without consulting their doctors, who can often suggest safer alternatives or adjust dosing.
Treatment
Treatment for spina bifida requires a coordinated team approach involving multiple specialists throughout a person's life. For babies born with an open neural tube defect, surgery within the first 48 hours is usually necessary to close the opening, protect the spinal cord from further damage, and reduce infection risk. This initial surgery doesn't restore lost neurological function, but it prevents additional complications and allows for better long-term outcomes. Many children with spina bifida also develop hydrocephalus, requiring a shunt system to drain excess fluid from the brain and prevent dangerous pressure buildup. Physical therapy typically begins in infancy to maintain joint flexibility, strengthen muscles, and help children reach their maximum potential for movement and mobility. Occupational therapists work with families to adapt daily activities and recommend assistive devices like braces, crutches, or wheelchairs as children grow. Bladder and bowel management becomes a central focus of care since most people with spina bifida have some degree of neurogenic bladder and bowel. This often involves intermittent catheterization, medications, and sometimes surgical procedures to prevent kidney damage and maintain continence. Educational support helps address learning difficulties that can accompany spina bifida, while regular monitoring by various specialists ensures early detection and treatment of complications. Recent advances include fetal surgery performed while the baby is still in the womb, which has shown promise in reducing the severity of symptoms and the need for shunts in carefully selected cases. Ongoing research into stem cell therapy and nerve regeneration offers hope for future treatments that might restore some lost function.
Living With Spina Bifida
Daily life with spina bifida involves developing routines and strategies that promote independence while managing medical needs. Many families find that establishing consistent schedules for catheterization, medications, and therapy helps create a sense of normalcy. Children benefit from age-appropriate explanations of their condition and gradual involvement in their own care, building confidence and self-advocacy skills they'll need as adults. Schools play a crucial role in supporting children with spina bifida through individualized education programs that address both academic and physical needs. Key daily considerations include: - Learning proper catheterization techniques for bladder management - Performing regular skin checks to prevent pressure sores - Maintaining physical activity appropriate to individual abilities - Following up regularly with the medical team for preventive care - Using assistive devices or mobility aids as needed - Staying current with vaccinations and health screenings Building a strong support network makes a significant difference in quality of life. Many families connect with local spina bifida associations, which provide resources, social opportunities, and connections with other families facing similar challenges. Adults with spina bifida often pursue higher education and careers, though they may need workplace accommodations or accessibility modifications. Relationships and family planning remain possible, with genetic counseling available for those considering having children. The key to thriving with spina bifida lies in focusing on abilities rather than limitations, maintaining open communication with healthcare providers, and celebrating achievements along the way.
