The effects of glucose on the memory and attention of newborn human infants /

The objective of this randomized, double-blind, placebo-controlled trial was to determine whether glucose enhanced memory for a repeated auditory stimulus in human newborns. Infants consumed water or glucose (2-g/kg) solution. Memory test phases were: Orientation (turning towards the stimulus); Habituation (not turning towards), indicating familiarity; Delay (100 seconds); Spontaneous Recovery (stimulus representation: not turning towards indicates remembering, while turning towards indicates forgetting), and Novelty (turning towards a different word confirms wakefulness). Decreased head-turning towards during Spontaneous Recovery indicates enhanced memory. Blood glucose levels were measured after testing. / "Glucose" infants had higher blood glucose levels than "water" infants (p < 0.001). "Glucose" infants had significantly decreased turns towards during Spontaneous Recovery compared to "water" infants (p = 0.008), indicating memory enhancement. / Therefore, glucose specifically enhances memory for a repeated auditory stimulus in newborn humans. Elevating blood glucose levels by approximately 2 mmol/L appears to be sufficient for memory enhancement in healthy newborns.
