Caffeine and brain development in very preterm infants

Abstract

Objective: Caffeine improves neurological outcome in very preterm infants, but the mechanisms responsible for this neurological benefit are unknown. The objective of this study was to assess whether caffeine influenced brain macro- or microstructural development in preterm infants. Methods: Seventy preterm infants <1,251 g birthweight randomly allocated to either caffeine (n = 33) or placebo (n = 37) underwent brain magnetic resonance imaging (MRI) at term-equivalent age; white and gray matter abnormalities were qualitatively scored, global and regional brain volumes were measured, and white matter microstructure was evaluated using diffusion-weighted imaging. Results: There were no signific..
