Spina bifida is a neural tube defect—a birth defect where the spine does not form or close properly early in fetal development WikipediaCDC. It can range from mild to severe depending on how much the spinal cord and nerves are affected.
Main Types of Spina Bifida
There are three primary forms, often taught in educational quizzes and worksheets:
1. Spina Bifida Occulta
-
Definition: The mildest and most common type. A small gap exists in the vertebrae, but the spinal cord and nerves remain within the spinal canal WikipediaNYU Langone HealthHealthline.
-
Symptoms: Typically no noticeable signs. Some individuals may have a tuft of hair, dimple, dark spot, or birthmark on their lower back NYU Langone HealthWikipediaVerywell Health.
-
Prevalence: Occurs in about 12% of people, often incidentally found via imaging Verywell Health.
-
Complications: Rarely, tethered cord syndrome may develop, leading to neurological symptoms later NYU Langone HealthWikipediaVerywell Health.
2. Meningocele
-
Definition: A sac of spinal fluid protrudes through an opening in the spine, but the spinal cord remains intact within the canal Mayo ClinicHealthyChildren.orgHealthline.
-
Symptoms: May include mild bladder or bowel issues, but serious nerve damage is uncommon Mayo ClinicCleveland Clinic.
-
Severity: Less common, with limited neurological involvement.
3. Myelomeningocele
-
Definition: The most severe form. The spinal canal remains open, and a sac protrudes containing both spinal fluid and neural tissue (cord and nerves) Mayo ClinicHealthlineHealthyChildren.org.
-
Symptoms: Typically results in significant leg weakness or paralysis, bladder and bowel dysfunction, orthopedic issues (clubfoot, scoliosis), and often hydrocephalus (fluid buildup in the brain) WikipediaHealthlineWikipediaJohns Hopkins MedicineHealthyChildren.org.
-
Interventions: Often requires surgical repair, possibly prenatal or postnatal, and ongoing multidisciplinary care WikipediaMayo ClinicMayo ClinicVerywell Health.
Other Related Variants (Closed Neural Tube Defects)
-
Lipomyelomeningocele and lipomeningocele are closed forms (sometimes called closed spinal lesions) that fall under spina bifida occulta but may involve tethering of spinal cord or fatty masses attached to neural tissue NINDSshinecharity.org.ukJohns Hopkins Medicine.
-
Diastematomyelia, another closed variant, involves a split spinal cord and may present with hair, dimples, or neurological deficits, often detected later in childhood
📊 Summary Table
| Type | What Happens | How Serious? |
|---|---|---|
| Occulta | Gap in bones, no nerve damage | Mild |
| Meningocele | Fluid sac, no nerves in sac | Moderate |
| Myelomeningocele | Sac has nerves, spinal cord, and fluid | Most severe |
| Other (Closed forms) | Fatty tissue, split cord, nerve pulling | Varies |
🧠What is Hydrocephalus?
💧 Too much fluid in the brain
-
Common in people with myelomeningocele
-
Can cause headaches, vision problems, or learning difficulties
-
Treated with a shunt (a tube to drain fluid)
⚠️ What is Tethered Cord Syndrome?
⛓ The spinal cord gets stuck and stretched
-
Can cause pain, weakness, or bladder problems
-
Might happen with spina bifida occulta
🛡 How to Lower the Risk
-
Take folic acid before and during pregnancy
-
Go to prenatal appointments and scans
-
Doctors can see spina bifida in a baby using special tests

<p>
Spina bifida is a condition where the spine does not form properly in the womb. It is a type of neural tube defect that can affect movement, nerves, and how the body works.
