Which statement best reflects the range of diagnoses associated with prematurity?

• A. PVL, Hydrocephaly, Hypoxic injury, and hemorrhaging are prematurity-associated
• B. Cerebral palsy and Down syndrome are prematurity-associated
• C. ALS and MS are prematurity-associated
• D. Brain tumors are prematurity-associated

Answer: (A)

The main idea here is how prematurity affects the brain. When babies are born very early, their brain’s blood vessels are immature and fragile, especially around the ventricles. This makes them prone to injuries like periventricular leukomalacia (PVL), which is white-matter damage near the ventricles due to reduced blood flow or oxygen. Intraventricular hemorrhages can occur because the germinal matrix vessels are fragile, and these bleeds can block CSF pathways and lead to hydrocephalus. Hypoxic injury, from not getting enough oxygen around birth, also contributes to brain damage in prematurity. All of these—PVL, hydrocephalus/hemorrhaging, and hypoxic injury—are well-documented prematurity-associated diagnoses. Other options pair conditions that aren’t typically linked to prematurity. Down syndrome is a genetic condition, ALS and MS are neurodegenerative diseases, and brain tumors are not specifically tied to being born prematurely. While cerebral palsy can occur in preterm infants, the statement that includes conditions like Down syndrome or degenerative diseases doesn’t accurately reflect the prematurity-specific spectrum.
