Neurodevelopmental Outcomes of Preterm Infants Fed Human Milk: A Systematic Review.

The neurodevelopmental benefits of breast milk feedings for preterm infants have been controversial. However, the effect on preterm infant neurodevelopment is sustained into childhood. The effects of breast milk feeding during the neonatal period and the duration of breastfeeding display effects on cognition into adolescence. The volume of breast milk received is a key factor in these effects. Additionally, emerging studies support the effects of human milk on structural brain development, such as increased white matter development and increased cortical thickness. The components of breast milk thought to mediate improved cognitive outcomes include long-chain polyunsaturated fatty acids and human milk oligosaccharides.
