High maternal caffeine consumption is associated with ADHD-like behavior at 11 years old.
Danish researchers found a significant trend associating increasing levels of coffee consumption during pregnancy and the risk of having children with a behavioral profile that fits ADHD. The strongest correlation was between caffeine consumption at 15 weeks gestation, suggesting a developmental window when fetal brains may be more sensitive to the effects of caffeine. More research is needed before cause and effect can be determined.
PositiveTip: Pregnant women might want to avoid caffeine, especially during the early weeks of pregnancy!
