Which cognitive domain may be affected in individuals with spina bifida, especially involving higher-order functions?

• A. Executive function
• B. Short-term memory
• C. Motor planning
• D. Verbal ability

Answer: (A)

Executive function refers to higher-order cognitive control processes that help you plan, organize, stay on task, switch between ideas, and regulate impulses. In individuals with spina bifida, especially when hydrocephalus or brain malformations are involved, the frontal-subcortical circuits that support these control processes can be affected. That makes tasks requiring multi-step planning, holding and manipulating information in working memory, and adjusting strategies in response to feedback more challenging. So executive function is the domain most closely tied to these higher-order abilities and tends to show the characteristic profile seen in spina bifida. Short-term memory focuses on holding information briefly, motor planning deals with coordinating movements, and verbal ability relates to language skills; while these may be affected to some degree, they do not capture the same pattern of higher-order cognitive control that executive function represents.
