Choline Supplements Linked to Lasting Cognitive Gains in Children with FASD
A follow-up of three randomized trials found that children with fetal alcohol spectrum disorder who received choline for nine months showed better cognitive outcomes five years later. Treated children had about 7% higher nonverbal IQ and 9% higher working memory scores than those given placebo. The results suggest choline could be a scalable intervention for neurodevelopmental difficulties caused by prenatal alcohol exposure.
FASD is an umbrella term for several diagnoses, affecting roughly 1%–5% of the global population and involving physical, cognitive, and behavioral difficulties. Earlier animal and pregnancy studies indicated choline might aid brain development after prenatal alcohol exposure. Three University of Minnesota randomized trials enrolled 104 children ages 2–5; 84 completed nine months of choline or placebo.
A five-year follow-up reassessed 58 children, average age 9. Treated children averaged 7% higher nonverbal IQ and 9% higher working memory, with medium-to-large effects. Higher doses correlated with larger gains, and some benefits were not apparent immediately after the trials. No differences appeared on other global cognition, memory, or parent-rated behavior measures.
If replicated, choline could offer an accessible early intervention for children with FASD, potentially easing cognitive and behavioral challenges that may affect learning and daily functioning. Families and schools might see benefits through improved working memory and nonverbal reasoning, though dosing, timing, and long-term effects still need clarification. Because FASD affects a notable share of the population, even modest gains could have broad public-health relevance.
