Which description best summarizes the link between folic acid, neural tube defects, and spina bifida?

• A. Neural tube defects such as spina bifida
• B. Cleft lip
• C. Down syndrome
• D. Clubfoot

Answer: (A)

Folic acid is essential for DNA synthesis and rapid cell division in early fetal development, especially as the neural tube forms and closes within the first month of gestation. If folate levels are insufficient, the neural tube may fail to close properly, leading to neural tube defects such as spina bifida. Adequate folic acid intake before conception and in early pregnancy reduces the risk of these defects. So the link is that neural tube defects, including spina bifida, are associated with folate status, and proper folic acid intake helps prevent them. Clinically, this underpins recommending folic acid supplementation for women of childbearing age and during early pregnancy.
