Which factor is associated with lower cognitive function, according to the source?

• A. Significant CNS infections
• B. Early closure
• C. CSF shunt intervention
• D. Antibiotic interventions

Answer: (A)

Significant CNS infections can cause lasting cognitive deficits because they injure the developing brain. Infections such as meningitis or ventriculitis trigger inflammation that can damage neurons and white matter, disrupting neural networks involved in attention, memory, processing speed, and executive function. This kind of injury during early development often translates into lower cognitive performance later on.

Early closure aims to reduce exposure and complications but isn’t described as a factor that directly lowers cognition. A CSF shunt indicates hydrocephalus and is part of managing brain pressure; outcomes depend on the extent of prior brain injury and any shunt-related issues, rather than the shunt itself being a primary cause of cognitive decline. Antibiotic interventions prevent infections and are protective, not associated with reduced cognitive function.
