Fetal Alcohol Spectrum Disorders (FASDs) are a group of preventable conditions that can occur when a fetus is exposed to alcohol before birth. The effects of FASDs can vary widely and can range from mild to severe. Fetal Alcohol Syndrome (FAS) is the most severe condition within the spectrum of FASDs. It is characterised by central nervous system (CNS) problems, growth deficiencies, distinct facial features, and other physical factors. FASDs can be difficult to diagnose as there is no direct test for them, and symptoms can resemble those of other disorders.

What You'll Learn
Facial features
Fetal Alcohol Spectrum Disorders (FASD) is an umbrella term for the range of defects resulting from prenatal alcohol exposure (PAE). Fetal Alcohol Syndrome (FAS) is a diagnosis within the FASD umbrella, and confirmation of prenatal alcohol exposure is not required for an FAS diagnosis. FAS is characterised by growth deficiencies, distinct facial features, and other physical factors in addition to central nervous system (CNS) involvement.
Three key facial features are considered in the diagnosis of FAS: short palpebral fissures (small eye-openings), a smooth philtrum, and a thin vermilion of the upper lip. However, several other facial features are commonly seen in individuals with FAS. These include:
- Microcephaly, reflecting structural damage to the brain
- Decreased brain volume and poor gyration
- Abnormal or absent corpus callosum
- Small cerebellum
The presence of these facial features is not solely indicative of FAS, as they may also be seen in individuals with other neurodevelopmental disorders. However, the severity of alcohol-related dysmorphology is predictive of the severity of alcohol-related neurobehavioural impairment.

Growth problems
Fetal Alcohol Syndrome (FAS) is a disability that causes a wide range of symptoms, including growth deficiencies. FAS is caused when a fetus is exposed to alcohol in the womb, which can occur at any stage of pregnancy, even before a woman knows she is pregnant. The alcohol enters the fetus's bloodstream through the placenta.
The syndrome can cause problems with growth, including height and
In addition to growth problems, FAS can also cause central nervous system (CNS) problems, distinct facial features, and other physical malformations. CNS involvement can be structural, for example, small brain size or alterations in specific brain regions, or functional, such as cognitive and behavioural deficits, motor and coordination problems.
FAS is a permanent and irreversible condition, but it can be treated. Early identification is critical for the well-being of individuals affected by FAS and their families, as it can help maximize treatment and build supportive networks.
To prevent FAS, it is recommended that women who are pregnant, might be pregnant, or are trying to become pregnant, should refrain from consuming alcohol.

Central nervous system issues
Fetal Alcohol Spectrum Disorders (FASD) are a group of preventable conditions that can occur when a fetus is exposed to alcohol. This exposure can interfere with the development of the baby's brain and other critical organs and physiological functions, leading to lifelong physical and mental defects.
Central nervous system (CNS) issues are a common factor in FASD. Evidence of CNS involvement can be structural, such as small brain size or alterations in specific brain regions, or functional, such as cognitive and behavioral deficits, motor and coordination problems, and hyperactivity. People with CNS problems related to FASD may also experience issues with learning, memory, attention span, communication, vision, or hearing. These problems can make it difficult for them to do well in school and get along with others.
CNS problems can also be seen in partial fetal alcohol syndrome (pFAS). Individuals with pFAS have some characteristics of fetal alcohol syndrome (FAS), such as changes to their facial features, but do not meet the full diagnostic criteria. They may exhibit a mix of CNS abnormalities along with growth problems and the aforementioned facial features.
Alcohol-related neurodevelopmental disorder (ARND) is another condition under the FASD umbrella, where individuals may experience intellectual disabilities, behavioral issues, and learning difficulties. They may struggle with math, memory, attention, judgment, and impulse control, which can negatively impact their school performance.
Neurobehavioral disorder associated with prenatal alcohol exposure (ND-PAE) is diagnosed when a child has been exposed to more than minimal levels of alcohol before birth (more than 13 drinks per month or more than 2 drinks in one sitting). These individuals may have significant behavioral issues, such as severe tantrums, and difficulty with daily tasks like bathing.

Learning and behavioural problems
Fetal Alcohol Spectrum Disorders (FASDs) are a group of preventable conditions that can occur when a baby is exposed to alcohol in the womb. FASDs can have lifelong effects, including physical, behavioural, and cognitive impairments.
Fetal Alcohol Syndrome (FAS) is the most severe form of FASD. People with FAS often experience learning and behavioural problems, which can vary in severity. These problems can include issues with memory, attention span, communication, and impulse control. They may also have a hard time in school, both academically and socially.
Learning disabilities are a common symptom of FAS. Individuals with FAS may struggle with schoolwork and have difficulties with math, memory, attention, and judgment. They may also have poor impulse control and exhibit hyperactivity. Early treatment of these symptoms can help lessen their severity and improve the child's overall development. Behavioural therapies can help address emotional and learning concerns, while parental training can provide families with strategies to help their child adapt to different situations.
Behavioural problems are also frequently observed in individuals with FAS. They may struggle with impulse control and exhibit inappropriate behaviours, such as acting out in sexually explicit ways. Additionally, they may have trouble getting along with others and experience difficulty in social situations.
The effects of FASDs, including FAS, can vary widely, and not all individuals will experience the same symptoms. However, it is important to note that FASDs are preventable if a developing baby is not exposed to alcohol. Early diagnosis and intervention are critical for the well-being of individuals with FASDs and their families.

Vision and hearing problems
Fetal Alcohol Syndrome (FAS) is caused by alcohol consumption during pregnancy, leading to lifelong physical and mental defects. FAS is the most severe form of Fetal Alcohol Spectrum Disorders (FASDs), a group of conditions resulting from prenatal alcohol exposure. FASDs can affect individuals differently, ranging from mild to severe symptoms.
Infants with FAS may exhibit specific physical characteristics, including abnormal facial features such as a thin upper lip, a smooth ridge between the nose and upper lip, wide-set eyes, and small eyes. They may also be born with a small head size and low body weight. These physical signs, along with growth problems, are crucial for diagnosing FAS.
As children with FAS grow older, they may experience a range of problems, including learning difficulties, attention deficits, behavioral issues, and poor school performance. The behavioral issues can include hyperactivity, impulsivity, and severe tantrums.
The effects of FAS are lifelong and can significantly impact the individual's ability to function in various aspects of life. Early identification of FAS is crucial for the well-being of affected individuals and their families, as it allows for the building of supportive networks and the management of symptoms.

Frequently asked questions
Fetal Alcohol Syndrome (FAS) is a condition that develops in a fetus when a pregnant woman drinks alcohol during pregnancy. It is the most severe end of what are known as fetal alcohol spectrum disorders (FASD). FAS is characterised by growth deficiencies, distinct facial features, and other physical factors, in addition to central nervous system (CNS) involvement.
The symptoms of fetal alcohol syndrome can vary. They may include abnormal facial features, such as a smooth ridge between the nose and upper lip, a thin upper lip, and small eyes, as well as growth deficiencies, such as low body weight and short height. Other symptoms may include sleep and sucking difficulties, vision or hearing problems, and delayed speech and language development.
The exact prevalence of fetal alcohol syndrome is difficult to determine due to the wide variety of symptoms and spectrum of severity. Studies have shown that fetal alcohol syndrome ranges from 0.5 to 9 cases per 1,000 live births, with higher rates in certain high-risk populations, such as those with low socioeconomic status and racial and ethnic minority populations.
Yes, fetal alcohol syndrome is preventable by abstaining from alcohol during pregnancy. The U.S. Surgeon General recommends that women who are pregnant, might be pregnant, or are thinking about getting pregnant should not drink alcohol at all.
