Key Takeaways
Spina bifida is a birth defect where the spine and spinal cord don't form properly during early pregnancy
It affects about 1 in 2,800 babies born in the United States each year
Taking folic acid before conception and during early pregnancy can substantially reduce the risk of spina bifida and other neural tube defects, but it cannot prevent every case.
The condition ranges from mild (spina bifida occulta) to severe (myelomeningocele)
Early treatment and ongoing care can help people with spina bifida live full, active lives
Overview
Spina bifida is a neural tube defect that occurs when a baby's spine and spinal cord don't develop properly in the womb. The neural tube is the structure that forms the brain and spinal cord. When this tube doesn't close completely during the first month of pregnancy, spina bifida develops.
This condition affects the backbone and sometimes the spinal cord itself. The word "spina bifida" means "split spine" in Latin. It happens in about 1 out of every 2,800 babies born in the United States. Spina bifida is one of the most common birth defects affecting the central nervous system.
The condition varies greatly in severity. Some people have mild forms that cause few problems, while others face significant challenges with mobility and daily activities. With proper medical care and support, many people with spina bifida lead independent, fulfilling lives. There are three main types of spina bifida: occulta, meningocele, and myelomeningocele. Each type affects the body differently. Medical teams can help families understand which type their child has and what to expect. Understanding Spina Bifida: Causes, Symptoms, and Treatment Options provides detailed information about this complex condition.
Symptoms & Signs
The symptoms of spina bifida depend on the type and severity of the condition. Some people may have no visible signs, while others have obvious physical differences at birth.
Primary Symptoms
Visible opening or sac on the back: In severe cases, there may be a fluid-filled sac protruding from the spine
Weakness or paralysis in the legs: This can range from mild weakness to complete inability to move the legs
Bowel and bladder problems: Difficulty controlling urination and bowel movements is common
Learning difficulties: Some children may have problems with attention, memory, or processing information
Fluid buildup in the brain (hydrocephalus): This can cause head enlargement and increased pressure in the skull
Not everyone with spina bifida shows all these symptoms. Some people have only a few signs, while others experience many challenges. The location of the spine opening affects which symptoms appear. Lower spine openings usually cause less severe symptoms than upper spine openings.
When to Seek Care
Watch for signs of infection at the spina bifida site, such as redness, swelling, or discharge. Also monitor for symptoms of hydrocephalus, including vomiting and irritability. Contact the child’s doctor promptly about new or worsening symptoms, and seek urgent medical care for repeated vomiting, unusual sleepiness, or changes in consciousness.
When to Seek Immediate Care
Seek urgent medical care for signs of infection, sudden changes in neurological function, severe headache, repeated vomiting, unusual sleepiness, or changes in consciousness. Call emergency services for severe or rapidly worsening symptoms.
Causes & Risk Factors
Age
The relationship between maternal age and spina bifida risk is uncertain, and age alone is not considered a major established risk factor.
Genetics
Previous child with spina bifida increases risk to 3-5%
Lifestyle
Low folic acid intake, obesity, and diabetes increase risk
Other Conditions
Certain medications and high fever during pregnancy

Diagnosis
Diagnosis
Medical History & Physical Examination
Doctors often diagnose spina bifida before birth through routine prenatal screenings. During pregnancy, blood tests can detect elevated levels of alpha-fetoprotein, which may indicate a neural tube defect. Ultrasound imaging can show the spine and detect openings or abnormalities. If spina bifida isn't detected during pregnancy, doctors diagnose it at birth through physical examination of the baby's back and spine.
Diagnostic Testing
Ultrasound during pregnancy: Shows images of the developing baby's spine and can detect spina bifida as early as 16 weeks
Alpha-fetoprotein blood test: Measures protein levels in the mother's blood that may be elevated with spina bifida
MRI after birth: Provides detailed images of the spine and spinal cord to determine the extent of the condition
CT scan: May be used to check for hydrocephalus or other complications

Treatment Options
Treatment for spina bifida focuses on managing symptoms and preventing complications. The approach depends on the type and severity of the condition.
Conservative Treatments
Physical therapy: Helps maintain muscle strength and improve mobility through exercises and stretching
Occupational therapy: Teaches daily living skills and helps adapt activities for individual needs
Bladder and bowel management: Includes catheterization techniques and bowel programs to maintain continence
Assistive devices: Braces, wheelchairs, and other equipment help with mobility and independence
Advanced Treatments
Surgery to close an open myelomeningocele: Usually performed within 24-48 hours after birth. For selected pregnancies, specialized centers may also discuss surgery before birth, which has potential benefits and important risks.
Shunt placement for hydrocephalus: A drainage system diverts excess fluid from the brain to prevent complications
Orthopedic surgery: May be needed to correct bone and joint problems that develop over time
Treatment plans work best when they're customized for each person. Doctors consider the individual's age, severity of condition, and personal goals. Regular check-ups help doctors adjust treatments as the person grows and changes. Many people benefit from working with a team of specialists to manage all aspects of their condition.
Living with the Condition
Daily Management Strategies
People with spina bifida can live independently with proper planning and support. Regular medical checkups help catch problems early. Many people benefit from working with a team of specialists including neurologists, urologists, and physical therapists.

Skin care is especially important for people with limited sensation in their legs. Checking for pressure sores and injuries daily helps prevent serious complications. Many people use wheelchairs or other mobility aids to stay active and independent. Building routines for self-care makes managing the condition easier. Having a supportive family and healthcare team also makes a big difference.
Exercise & Movement
Regular exercise is important for maintaining strength and overall health. Swimming is often recommended because it's gentle on joints while providing excellent cardiovascular exercise. Physical therapy exercises help maintain flexibility and prevent muscle contractures. People should avoid activities that could injure areas with decreased sensation.
Working with a physical therapist helps create safe exercise plans. Many people enjoy activities like basketball, wheelchair sports, and dancing. Staying active improves both physical and mental health. Exercise also helps prevent weight gain and secondary health problems.
Prevention
Take 400 micrograms of folic acid daily before getting pregnant and during the first trimester
Eat foods rich in folate, such as leafy green vegetables, citrus fruits, and fortified cereals
Avoid excessive heat exposure during early pregnancy, such as hot tubs or saunas

Starting folic acid supplementation at least one month before trying to conceive is ideal. People who have had a previous pregnancy affected by spina bifida or another neural tube defect should consult a healthcare professional before conception; 4 milligrams of folic acid daily may be recommended from at least one month before conception through the first three months of pregnancy. Maintaining a healthy weight and eating nutritious foods supports pregnancy health. Getting regular prenatal care helps monitor the developing baby throughout pregnancy.
Frequently Asked Questions
Yes, spina bifida can usually be detected during pregnancy through blood tests and ultrasound. Most cases are diagnosed between 15-20 weeks of pregnancy. Early detection allows parents to prepare and plan for specialized care.
Walking ability depends on the type and location of spina bifida. Some children walk without assistance, others use braces or crutches, and some use wheelchairs. Physical therapy and proper medical care can help maximize mobility potential.
Spina bifida has a genetic component, but it's not directly inherited. If you've had one child with spina bifida, the risk for future pregnancies increases to about 3-5%. Understanding Ventricular Tachycardia: Symptoms, Causes, Diagnosis, and Treatment discusses how genetic factors influence various health conditions.
Many people with spina bifida live well into adulthood, but life expectancy varies with the type and severity of the condition and complications such as hydrocephalus, infection, and kidney problems. The severity of the condition and presence of complications like hydrocephalus can affect outcomes.
No, spina bifida is a birth defect that occurs during fetal development. However, some people may not be diagnosed until adulthood if they have a mild form called spina bifida occulta that causes few symptoms.
