Children with spina bifida are at risk of progressive deterioration in which two domains?

Children with spina bifida are at risk of progressive deterioration in which two domains?

• A. Neurologic impairments and CNS deterioration
• B. Endocrine changes and renal impairment
• C. Muscle hypertrophy and joint stiffness
• D. Respiratory failure and liver dysfunction

Answer: (A)

The main concept is that spina bifida can lead to ongoing changes in the nervous system, not just static physical findings. Children with this condition are at risk for progressive deterioration in two related areas: neurologic impairments, meaning increasing weakness, sensory loss, or changes in reflexes and coordination; and central nervous system deterioration, which reflects evolving problems in the brain and spinal cord itself, such as hydrocephalus progression, Chiari II malformation effects, or syringomyelia. Over time, issues like tethered cord syndrome can cause the spinal cord to be stretched as a child grows, leading to new or worsening motor and sensory deficits. Syringomyelia can form a syrinx within the spinal cord, producing gradual changes in sensation and strength. Concurrent CNS changes, including worsening hydrocephalus or hindbrain herniation, can produce headaches, cognitive or balance problems, and other central nervous system signs. Together, these processes explain why deterioration may appear in both functional neurologic abilities and central nervous system structure and function. In contrast, the other options describe problems that aren’t the primary progressive domains linked to spina bifida in the same way: endocrine or renal changes, or purely musculoskeletal or visceral failures, don’t capture the dual risk to both neurologic function and CNS integrity that characterizes progression in this condition.
