What is Fetal Alcohol Syndrome (FAS)? by Rehab Recovery Centers
Fetal alcohol syndrome (FAS) is a condition that occurs when a pregnant person drinks during their pregnancy, negatively affecting the fetus. This condition is a syndrome, which means that a group of symptoms happen together due to a disease or abnormal condition. When someone has fetal alcohol syndrome, they have the most severe form of fetal alcohol spectrum disorder (FASD).
When a developing baby is exposed to alcohol before birth they can be affected in many ways. Depending on how much alcohol they were exposed to, they can experience mild to severe symptoms. Fetal alcohol spectrum disorders are a scale of conditions that range from mild to severe effects, with fetal alcohol syndrome being the most severe.
Other conditions that fall under the FASDs scale include:
- Partial fetal alcohol syndrome (pFAS)
- Alcohol-related neurodevelopmental disorder (ARND)
- Alcohol-related birth defects (ARBD)
- A neurobehavioral disorder associated with prenatal alcohol exposure (ND-PAE)
Fetal alcohol syndrome is a lifelong disorder that is not curable. This means that the physical defects and mental deficiencies usually persist for a person’s lifetime.
While this condition can be prevented by avoiding alcohol during pregnancy, the CDC reports that 0.2 to 1.5 infants for every 1,000 live births have FAS. Approximately 1 in 10 pregnant women report drinking during their pregnancy.
What Causes Fetal Alcohol Syndrome (FAS)?
Fetal alcohol syndrome is caused by a pregnant woman drinking any type of alcohol during their pregnancy. This includes hard liquor, beer, wine, and hard ciders. FAS cannot develop unless a woman drinks alcohol while they are pregnant.
The main reason that alcohol abuse is dangerous during pregnancy is because of how the alcohol passes through the system. When a pregnant person drinks alcohol, the substance is passed through their bloodstream and into the umbilical cord. Fetuses cannot metabolize alcohol like an adult, causing it to stay in their body for a long amount of time.
Alcohol interferes with the normal development of the fetus in many ways, including harming the central nervous system and the brain as a whole. For instance:
- Alcohol kills cells in various parts of the fetus, leading to damaged physical development
- Alcohol inhibits the way that nerve cells develop
- The alcohol constricts blood vessels which causes decreased blood flow to the placenta, causing a shortage of oxygen and nutrients
- Alcohol produces toxic byproducts, damaging the fetus’s brain cells
It is important to note that any amount of alcohol can result in the development of FAS. According to research, “Even 1 or 2 drinks of alcohol can cause damage to the fetal brain. No amount of alcohol has been proven safe to drink during pregnancy.”
What are the Symptoms of FAS?
Fetal alcohol syndrome causes symptoms like mental and physical defects. This can include facial deformities, limb defects, delays in bodily development, and mental or emotional challenges that can significantly impact the person’s ability to function in their daily lives throughout childhood and adulthood.
The physical defects caused by FAS may include:
- Small head and brain size
- Vision issues
- Hearing problems
- Deformities in the joints, limbs, and fingers
- Facial features like small eyes, thin upper lip, or a ridge between the nose and upper lip
FAS may cause neurological issues such as:
- Issues with learning
- Coordination and balance problems
- Issues with reasoning
- Mood swings
FAS can also cause behavioral symptoms like:
- Poor social skills
- Difficulty in school (getting in trouble, failing classes, etc)
While fetal alcohol syndrome affects infants and fetuses, it continues to affect a person throughout their life. Some of the symptoms may develop later on, while others begin at birth.
Diagnosing Fetal Alcohol Syndrome
There is no specific lab test that can confirm whether a child has fetal alcohol syndrome. Additionally, diagnosing this condition may be difficult as the mother may not disclose their drinking habits during the pregnancy. The symptoms of this condition can mimic other disorders so people may be wrongly diagnosed with autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), or Williams syndrome.
To diagnose this condition doctors look for the following traits:
- Unusual facial features
- Lower than average height
- Lower than average weight
- Small head size
- Symptoms of ADHD
- Poor coordination
Doctors will ask the mother about her drinking history during the pregnancy. While only one drink can lead to FAS, the more a mother drinks, the more likely their child will develop this syndrome. However, as mentioned, mothers may be reluctant to disclose their previous drinking habits – complicating the diagnosis process.
How is FAS Treated?
Fetal alcohol syndrome is not curable but many of the symptoms are manageable. Certain features can improve a child’s development and outlook regarding FAS, including:
- Being diagnosed before the age of 6
- Being in a loving and nurturing home during their school years
- Not being exposed to violence
- Getting special education and social services
Early treatment of this condition can significantly improve some symptoms and lessen the developmental issues that the child experiences.
Treatment options for FAS include:
- Using medications for attention and behavioral issues
- Behavior and education therapy for emotional and learning issues
- Training the parent to better help the child manage their symptoms
According to research, between 50 to 90% of people with FASDs meet the criteria for ADHD. This means that undergoing treatment for ADHD may significantly improve a person’s ability to function in their daily life.
