Facial abnormalities, including wide-set and narrow eyes, and a smooth ridge between the nose and upper lip
Fetal Alcohol Syndrome (FAS) is a preventable condition that occurs when a woman consumes any amount of alcohol during pregnancy. It is the most severe condition within a group of conditions known as Fetal Alcohol Spectrum Disorders (FASDs). FAS is a permanent and lifelong condition that can cause physical and mental defects in the developing fetus.
One of the hallmark symptoms of FAS is abnormal facial features, which can include a smooth ridge or connection between the nose and upper lip, known as the philtrum. This feature is indicative of underdevelopment of the medial nasal processes, which also leads to a short nose and thin upper lip. The philtrum in individuals with FAS may be longer and smoother than average. Small eye openings and narrow eyes are also common facial abnormalities associated with FAS.
These distinctive facial characteristics can serve as a physical indicator of FAS, even in the absence of confirmation of prenatal alcohol exposure. The pattern of physical features in FAS is considered specific, often including a combination of a smooth philtrum, short nose, thin upper lip, and small eye openings.
While FAS cannot be cured, it can be prevented by abstaining from alcohol consumption during pregnancy. It is important to note that even small amounts of alcohol consumed during pregnancy can potentially harm the developing fetus.

Central nervous system (CNS) problems, including issues with learning, memory, attention, communication, vision, and hearing
Fetal Alcohol Syndrome (FAS) is a preventable, permanent condition that occurs when a woman consumes any amount of alcohol during pregnancy. FAS is the most severe condition within a group of conditions known as Fetal Alcohol Spectrum Disorders (FASDs). FASDs are a group of conditions that can occur in a person exposed to alcohol before birth and can have lifelong effects, including central nervous system (CNS) problems.
CNS problems are a common feature of FASDs, and they can manifest in various ways. These problems can include issues with learning, memory, attention, communication, vision, and hearing. People with FASDs may experience a range of cognitive disabilities, including difficulties with learning and memory. They may also struggle with attention and hyperactivity, as well as poor impulse control.
The brain is particularly vulnerable to the harmful effects of alcohol during early pregnancy, as this is when rapid development is taking place. Alcohol consumption during pregnancy can interfere with the baby's brain growth and development, leading to CNS abnormalities. These abnormalities can result in a range of issues, including problems with communication and vision.
Vision problems in individuals with FASDs may include difficulties with visual processing, such as problems with visual attention, visual-spatial abilities, and visual memory. Hearing issues may also be present, with some people experiencing problems with auditory processing or even hearing loss.
The effects of FASDs on the CNS can vary from person to person, and the severity of the symptoms can depend on various factors, including the amount and frequency of alcohol consumption during pregnancy. However, it is important to note that there is no safe level of alcohol consumption during pregnancy, and the only way to prevent FASDs is to avoid drinking alcohol entirely while pregnant.

Growth problems
Fetal Alcohol Syndrome (FAS) is a preventable condition that occurs when a fetus is exposed to alcohol in the womb. FAS is the most severe condition within a group of conditions known as fetal alcohol spectrum disorders (FASDs). FASDs can cause central nervous system problems, physical malformations, and multiple issues with learning and behaviour.
People with FAS may have restricted growth, including height and head size. FAS can also affect other bodily systems and organs, such as the kidneys and liver. In adulthood, common symptoms and signs of FAS include alcohol-related birth defects (ARBDs), which can cause problems with the heart, skeleton, ears, and eyes.
The symptoms of FAS vary in intensity, and early identification can improve health outcomes. While there is no cure for FAS, the disorder can be treated, and receiving treatment as soon as possible in childhood can help decrease the likelihood of developing secondary effects in life.

Alcohol-related neurodevelopmental disorder (ARND), which can cause intellectual disabilities, behavioural problems, and poor performance in school
Fetal Alcohol Syndrome (FAS) is a preventable condition that occurs when a woman consumes any amount of alcohol during pregnancy. It is the most severe condition within a group of conditions called fetal alcohol spectrum disorders (FASDs). FASDs refer to a collection of disorders in which a person has been exposed to alcohol before birth. FASDs can cause lifelong behavioural, learning, and physical symptoms.
Alcohol-related neurodevelopmental disorder (ARND) is a type of FASD. ARND is a neurodevelopmental condition that causes cognitive impairments and problems with learning and behaviour that occur due to prenatal exposure to alcohol. Those with ARND may experience intellectual disabilities, behavioural problems, and poor performance in school. ARND can cause difficulties in areas such as regulating emotions and reactions, and problems with impulse control.
Diagnosis of ARND is difficult because individuals do not demonstrate the characteristic facial features associated with FAS. However, individuals with ARND may present with a smaller than normal head size, poor coordination, and problems with attention. While attentional problems in ARND are similar to those found in attention-deficit/hyperactivity disorder (ADHD), the underlying impairment in attention pathways may be different.
There is no cure for ARND, but early intervention and support can help and may improve development during childhood. Special education and social services support can help children with ARND better reach their potential.

Alcohol-related birth defects, including defects in the heart, kidneys, bones, or hearing
Alcohol-related birth defects (ARBDs) are physical differences in a child's growth due to alcohol exposure during pregnancy. ARBDs are a type of fetal alcohol spectrum disorder (FASD) that does not cause neurological symptoms. Instead, they affect how parts of the body develop, such as the bones, heart, kidneys, or hearing.
ARBDs can cause physical changes in how the body's organs develop, including the heart and kidneys. These defects can be present from birth or become apparent as the child grows. For example, ARBDs can lead to ureteral duplications, where two tubes transport urine from the same kidney to the bladder.
ARBDs can also affect bone development, leading to skeletal differences such as scoliosis, which can cause serious complications like spinal cord compression. These defects can vary widely, and some people may have minor symptoms or none at all, while others may experience significant symptoms requiring ongoing treatment.
Hearing problems are also possible in individuals with fetal alcohol syndrome, although it is not specified whether this is due to ARBDs or other FASDs. However, FASDs can cause a wide range of physical, behavioural, and cognitive impairments, including CNS problems and specific facial anomalies.
Fetal alcohol syndrome (FAS) is caused by alcohol consumption during pregnancy and can result in lifelong physical and mental defects. It is a permanent condition that can interfere with the baby's development, causing issues such as abnormal facial features, growth deficits, and specific physical signs and symptoms that develop through childhood. FAS is preventable, but the only way to prevent it is to avoid drinking alcohol during pregnancy.

Frequently asked questions
Fetal Alcohol Spectrum Disorder (FASD) is a group of preventable conditions that can occur when a person is exposed to alcohol before birth.
Symptoms of fetal alcohol syndrome can be physical, behavioural, or cognitive. Physical symptoms include abnormal facial features, such as wide-set and narrow eyes, and a smooth ridge between the nose and upper lip. Behavioural symptoms can include poor performance in school and impulse control issues. Cognitive symptoms can include problems with learning, memory, attention span, communication, vision, or hearing.
Diagnosing fetal alcohol syndrome can be difficult because there is no medical test, like a blood test, for these conditions. A healthcare provider will make a diagnosis by looking at the child's signs and symptoms and asking whether the mother drank alcohol during pregnancy.
Fetal alcohol syndrome is completely preventable if a developing baby is not exposed to alcohol. If you are pregnant and struggling with an alcohol problem, talk to a midwife or doctor.
