3. What Causes Anencephaly?

The reason most infants develop anencephaly is unknown. Some develop the condition due to gene or chromosome mutations. In the majority of cases, the baby's family doe not have any history of anencephaly. The mother's contact with certain environmental factors, such as toxins, medications, and even food and drinks, may also play a part in anencephaly. However, scientists do not currently know enough about these potential risk factors to extend any warning or guidelines to pregnant women. Exposure to high temperatures from a high fever or a hot tub or sauna may increase the risk of neural tube defects. Additionally, the Cleveland Clinic asserts that specific prescription medications, including those for diabetes, may increase the risk of anencephaly. An inadequate intake of folic acid during pregnancy is a significant risk factor for having a baby with anencephaly or other neural tube defects.
