Want to raise a happy & healthy Baby?
Updated on 3 November 2023
In every pregnancy, there is a chance of congenital disabilities. One of the most serious and rarest forms of congenital disability is Anencephaly. This disorder affects the development of the brain and the skull and is usually fatal. Babies born with this disability often die shortly after birth. A combination of genetic and environmental factors also causes the condition.
Anencephaly is surprisingly a quite rare condition. Awareness of the causes and risk factors is essential to preventing this disorder. Here, we will explain Anencephaly meaning, its causes, and symptoms, along with risk factors and treatments.
Anencephaly, also known as "open skull," is a developmental disorder of the neural tube that causes serious alterations in the growth of the fetus.
In Anencephaly, the brain and skull do not develop as expected. The neural tube fails to close completely, resulting in an absent or incomplete brain, skull bones, and scalp.
This rare disorder occurs in only one out of every 5,000 to 10,000 births. It is more common among newborn baby girls than boys.
Anencephaly is a serious congenital disability. In most cases, it can be detected before delivery using prenatal tests.
Mothers aged 26-30 years and older are more likely to give birth to babies with the disorder.
The symptoms of Anencephaly can vary from one baby to another. They may include:
Absent or incomplete brain development
Missing cranial bones
Incomplete scalp and skull formation
Small head circumference
Brain matter is exposed at the top of the head
No development of the frontal lobe
The cerebellum may be absent or underdeveloped
Subnormal reflexes and movements
Missing or deformed facial features
Absence of skull bones
Anencephaly can be diagnosed before the baby is born through prenatal tests. Ultrasound and amniocentesis are two common tests used to diagnose babies with Anencephaly.
Ultrasound is a non-invasive test that uses sound waves to create images of the baby in the womb. It can help to detect missing or deformed skull bones, an absence of brain tissue, and other anomalies.
A small sample of the amniotic fluid around the baby is collected and tested in amniocentesis. This test can detect the presence of a specific enzyme released by anencephalic babies.
Till now, there has been no known Anencephaly treatment available. Babies born with this condition usually die within a few hours or days after birth. However, supportive care can make the baby more comfortable for some time.
Sometimes, a baby born with Anencephaly may be kept alive on life support. This allows family members to spend time with the baby and say their goodbyes.
Anyone can have a baby with Anencephaly, but certain risk factors increase the chances.
Below are the possible Anencephaly causes & risk factors:
Inherited genetic factors
Sometimes, Anencephaly can be inherited. It can be a genetic mutation of parents that affects the development of the baby.
Folic acid deficiency
Inadequate levels of folic acid (vitamin B9) in the body during pregnancy can increase the risk of Anencephaly.
Certain medications, such as valproic acid, can increase the risk of this disability.
Pregnant women with diabetes are at a higher risk of having a baby with this disability.
Infections such as rubella during pregnancy can increase the risk of Anencephaly.
Exposure to environmental toxins
Exposure to hazardous materials such as radiation, alcohol, or drugs can increase the risk of this disability.
As there is no known treatment for Anencephaly, it is important to focus on prevention.
Here are a few steps that can help reduce the risk:
Take folic acid supplements before and during pregnancy
Folic acid can reduce the risk of neural tube defects. Speak to the doctor about the recommended dosage and when to begin taking folic acid.
These have all been linked to a higher risk of Anencephaly and other birth defects.
Maintain a healthy diet before, during, and after pregnancy
Eating a balanced diet with the recommended intake of vitamins and minerals can help reduce the risk of Anencephaly.
Avoid any hot, steamy environments.
High temperatures can increase the risk of Anencephaly and other neural tube defects. So, avoid any hot, steamy environments, such as hot tubs, saunas, or steam rooms.
Weight and health management
Health management and maintaining a healthy weight before and during pregnancy can help reduce the risk.
No scientific evidence suggests stress can increase the risk of Anencephaly in a fetus. One should reduce stress levels as much as possible during pregnancy. Stress can affect overall health, which can cause complications with pregnancy and delivery.
No, it is a fatal condition and babies with this condition do not survive long after birth.
