Anencephaly is a rare birth defect in which the baby's brain and skull do not fully form. Babies with this birth defect die during pregnancy or soon after being born.
Anencephaly is a type of neural tube defect. Neural tube defects are birth defects of the brain, spine, or spinal cord. These birth defects happen early in pregnancy, often before a woman knows she is pregnant.

We do not know the specific causes of Anencephaly. However, women can reduce their risk by getting enough folic acid, especially if you are able to get pregnant. The best way to get enough folic acid is to take a daily multivitamin with 400 µg folic acid. Some women may need higher amounts of folic acid, so check with your doctor. Women should also eat foods with folate. Foods with naturally high amounts of folate include beans, lentils, cereals, breads, oranges, avocados, seeds, nuts, spinach, dark leafy greens, and broccoli.
Visit the Centers for Disease Control and Prevention webpage for more information about folic acid.
For women not planning on becoming pregnant:
- Even if you are not trying to become pregnant, folic acid is an important part of a healthy diet.
- The fact is that about half of pregnancies are not planned. Getting enough folic acid helps make sure your body is healthy and ready if you become pregnant.
- All women ages 11-49 years with Apple Health (Medicaid) can get free multivitamins.
