Anencephaly is a rare condition where a baby’s brain and skull do not fully develop during early pregnancy. This occurs when the neural tube, which forms the brain and spine, doesn’t close completely.
This means the baby cannot develop higher brain functions and typically survives only a short time after birth. This is a heartbreaking and overwhelming diagnosis, and your CHRISTUS care team is here to provide compassionate care and support during this time.
Anencephaly is caused by a neural tube defect when the baby’s skull and brain do not form properly during early pregnancy.
A combination of genetic and environmental factors can cause anencephaly. These factors include insufficient intake of folic acid or other nutrients before and during pregnancy, exposure to some drugs or toxins, and certain infections during pregnancy.
Anencephaly is typically diagnosed during pregnancy through routine ultrasounds, which can detect abnormalities in the baby’s brain and skull development. Additional tests, like maternal blood work may be recommended to confirm the diagnosis. These early screenings allow your family to receive the information and support you need to navigate this challenging time.
