Exploring the neurological impact of prematurity: Shared mechanisms in periventricular leukomalacia (PVL), intraventricular hemorrhage (IVH), and hydrocephalus.

The earlier a baby is born, the greater the risk for developing complications, particularly relating to the development of the brain and neurological development. Common conditions seen with premature infants are periventricular leukomalacia (PVL), also known as white matter injury, intraventricular hemorrhage (IVH), and hydrocephalus. These conditions may result in varying degrees of structural damage to the brain parenchyma. This paper aims to discuss the shared pathophysiological mechanisms, clinical presentation, and current treatment approaches for PVL, IVH and hydrocephalus in premature infants with a focus on future research directions at improving neurodevelopmental outcomes. While the basic science continues to evolve rapidly, it is essential that future work prioritizes clinical translatability. Our review highlights an urgent need for therapies that balance efficacy and safety in these vulnerable patient populations. Collaborative efforts between clinicians and researchers will be vital to bridge this gap and ultimately improve outcomes for preterm infants affected by PVL, IVH, and hydrocephalus.
