How prenatal folic acid and vitamin B12 levels affect early brain development

Folic Acid, B12, and Neurodevelopmental Risk

NIH-funded research University of California at Davis · NIH-11332783

This project looks at whether too much or too little folic acid, and low vitamin B12 during pregnancy, change brain development and behavior in babies and young children.

What this research studies

From a patient point of view, the team is using animal models to mimic high and low prenatal folic acid intake and vitamin B12 deficiency to see how these changes affect the developing cerebral cortex. They will measure brain structure, cellular development, biochemical markers, and later behavior that relates to neurodevelopmental disorders like autism and anxiety. The work aims to connect specific prenatal nutrient levels to patterns of abnormal brain growth and function. Findings are intended to help shape safer prenatal nutrition recommendations in the future.

Who could benefit from this research

Good fit: People who are pregnant or planning pregnancy, parents of infants, and families with a history of neurodevelopmental disorders may find the results most relevant.

Not a fit: People who are not pregnant, not planning pregnancy, or whose concerns are unrelated to prenatal nutrition are unlikely to gain direct benefits from this preclinical project right now.

Why it matters

Potential benefit: If successful, the work could inform safer prenatal folic acid and B12 guidelines to lower the chance of neurodevelopmental problems in children.

How similar studies have performed: Previous human and animal studies have shown folate and B12 affect neural development and neural tube defects are prevented by folic acid, but the effects of excess folic acid on cortical development are less well established and this work is relatively novel.
