neural tube defect

Neural tube defects (NTDs) are birth defects of the brain, spine, and spinal cord that usually occur during the first month or trimester of pregnancy, often before a woman realizes she is pregnant. This is why women of childbearing age are advised to take a multivitamin with 400 micrograms of folic acid a day, as this is proven to help prevent NTDs.
