Fetal Alcohol Syndrome

What Is Fetal Alcohol Syndrome?

Women who drink alcohol during pregnancy can give birth to babies with fetal alcohol spectrum disorders (sometimes known as FASD). FASD is the umbrella term for a range of disorders. These disorders can be mild or severe and can cause physical and mental birth defects. Types of FASD include:

  • fetal alcohol syndrome (FAS)
  • partial fetal alcohol syndrome
  • alcohol-related birth defects
  • alcohol-related neurodevelopment disorder
  • neurobehavioral disorder associated with prenatal alcohol exposure

FAS is a severe form of the condition. People with FAS may have problems with their vision, hearing, memory, attention span, and abilities to learn and communicate. While the defects vary from one person to another, the damage is often permanent.

What Are the Causes of Fetal Alcohol Syndrome?

Causes Icon

When a pregnant woman drinks alcohol, some of that alcohol easily passes across the placenta to the fetus. The body of a developing fetus doesn’t process alcohol the same way as an adult does. The alcohol is more concentrated in the fetus, and can prevent enough nutrition and oxygen from getting to the fetus’ vital organs.

Damage can be done in the first few weeks of pregnancy when a woman might not yet know that she is pregnant. The risk increases if the mother is a heavy drinker.

According to many studies, alcohol use appears to be most harmful during the first three months of pregnancy. However, consumption of alcohol any time during pregnancy can be harmful, according to guidelines from the American Academy of Pediatrics.

What Are the Symptoms of Fetal Alcohol Syndrome?

Symptoms Icon

Since fetal alcohol syndrome covers a wide range of problems, there are many possible symptoms. The severity of these symptoms ranges from mild to severe, and can include:

  • a small head
  • a smooth ridge between the upper lip and nose, small and wide-set eyes, a very thin upper lip, or other abnormal facial features
  • below average height and weight
  • hyperactivity
  • lack of focus
  • poor coordination
  • delayed development and problems in thinking, speech, movement, and social skills
  • poor judgment
  • problems seeing or hearing
  • learning disabilities
  • intellectual disability
  • heart problems
  • kidney defects and abnormalities
  • deformed limbs or fingers
  • mood swings

How Is Fetal Alcohol Syndrome Diagnosed?

Diagnosis Icon

The earlier the diagnosis, the better the outcome. Talk to your doctor if you think your child might have FAS. Let your doctor know if you drank while you were pregnant.

A physical exam of the baby may show a heart murmur or other heart problems. As the baby matures, there may be other signs that help confirm the diagnosis. These include:

  • slow rate of growth
  • abnormal facial features or bone growth
  • hearing and vision problems
  • slow language acquisition
  • small head size
  • poor coordination

To diagnose someone with FAS, the doctor must determine that they have abnormal facial features, slower than normal growth, and central nervous system problems. These nervous system problems could be physical or behavioral. They might present as hyperactivity, lack of coordination or focus, or learning disabilities.

What Are the Treatments for Fetal Alcohol Syndrome?

While FAS is incurable, there are treatments for some symptoms. The earlier the diagnosis, the more progress can be made. Depending on the symptoms a child with FAS exhibits, they may need many doctor or specialist visits. Special education and social services can help very young children. For example, speech therapists can work with toddlers to help them learn to talk.

At Home

Children with FAS will benefit from a stable and loving home. They can be even more sensitive to disruptions in routine than an average child. Children with FAS are especially likely to develop problems with violence and substance abuse later in life if they are exposed to violence or abuse at home. These children do well with a regular routine, simple rules to follow, and rewards for positive behavior.


There are no medications that specifically treat FAS. However, several medications may address symptoms.

These medications include:

  • antidepressants to treat problems with sadness and negativity
  • stimulants to treat lack of focus, hyperactivity, and other behavioral problems
  • neuroleptics to treat anxiety and aggression
  • antianxiety drugs to treat anxiety


Behavioral training may also help. For instance, friendship training teaches kids social skills for interacting with their peers. Executive function training may improve skills such as self-control, reasoning, and understanding cause and effect. Children with FAS might also need academic help. For example, a math tutor could help a child who struggles in school.

Parents and siblings might also need help in dealing with the challenges this condition can cause. This help can come through talk therapy or support groups. Parents can also receive parental training tailored to the needs of their children. Parental training teaches you how to best interact with and care for your child.

Alternative Treatments

Some parents and their children seek alternative treatments outside of the medical establishment. These include healing practices, such as massage and acupuncture (the placement of thin needles into key body areas). Alternative treatments also include movement techniques, such as exercise or yoga.

How Can I Prevent Fetal Alcohol Syndrome?

Prevention Icon

You can avoid fetal alcohol syndrome by not drinking alcohol during pregnancy. If you’re a woman with a drinking problem who wants to get pregnant, seek help from a doctor. If you’re a light or social drinker, don’t drink if you think you might become pregnant anytime soon. Remember, the effects of alcohol can make a mark during the first few weeks of a pregnancy.
