Which factor is associated with greater cognitive ability in spina bifida patients?

• A. Early closure
• B. Antibiotic interventions
• C. CSF shunt intervention
• D. High-fat diet

Answer: (A)

Early closure reduces ongoing damage to the developing brain by limiting exposure of neural tissue to the harmful environment of an open spinal defect. When the defect is closed early, there’s less risk of brain structures being affected by pressure changes, hindbrain herniation (Chiari II), and hydrocephalus. This gentler, more stable environment supports better brain development, which translates into higher cognitive abilities later on.

Antibiotic interventions don’t inherently boost cognitive function; they are about infection management and don’t change brain development in the same way. CSF shunt interventions treat hydrocephalus rather than improve cognition directly, and a high-fat diet has no proven positive effect on cognition in spina bifida.
