Fetal Alcohol Syndrome (FAS) is a condition that occurs when a baby is born with a wide range of physical, behavioural, and learning problems as a result of alcohol exposure before birth. Alcohol easily passes through the placenta, the organ that nourishes a baby during pregnancy, and can interfere with the development of the baby's brain and other critical organs. This can lead to lifelong cognitive and behavioural deficits, growth deficiencies, distinct facial features, and other physical factors. FAS is preventable by abstaining from alcohol during pregnancy, and there is currently no cure. However, early intervention services, support from schools, and providing a stable home environment can help reduce the effects of FAS.

Fetal Alcohol Syndrome (FAS) is caused when a woman consumes alcohol during pregnancy
Fetal Alcohol Syndrome (FAS) is a life-long condition that occurs when a woman consumes alcohol during pregnancy. It is the most severe condition on the fetal alcohol spectrum disorder (FASD) scale, which includes partial fetal alcohol syndrome (pFAS), alcohol-related neurodevelopmental disorder (ARND), and neurobehavioral disorder associated with prenatal alcohol exposure (ND-PAE). FASDs are preventable if a developing baby is not exposed to alcohol.
When a pregnant woman consumes alcohol, it passes through her bloodstream to the fetus via the umbilical cord and placenta. The fetus cannot metabolize alcohol in the same way as an adult, so it stays in the body for a longer period. This can interfere with the normal development of the fetus, particularly the brain and central nervous system. Alcohol can kill cells in different parts of the fetus, causing abnormal physical development, and it can also disrupt the formation of nerve cells and their journey to form different parts of the brain.
The effects of alcohol on the fetus can vary depending on the amount consumed, the frequency, and the duration of alcohol consumption during pregnancy. However, there is no known safe amount or time to drink during pregnancy. Even small amounts of alcohol during pregnancy can cause FAS, and damage to the developing fetus can occur at any point, even before a woman knows she is pregnant. Therefore, it is recommended that women who are pregnant, trying to become pregnant, or thinking about getting pregnant should avoid alcohol entirely.
The key signs of FAS include growth deficiency, nervous system damage, and distinct facial features. Growth deficiencies can include low birth weight, small head circumference (microcephaly), and short palpebral fissure lengths. Nervous system damage can manifest as cognitive and behavioral deficits, motor and coordination problems, and learning difficulties. Distinct facial features associated with FAS include a smooth philtrum (ridge between the nose and upper lip), a thin upper lip, and small eyes.
Diagnosing FAS can be challenging, as there is no direct test for the condition. Pediatric providers may base a diagnosis on the child's size, specific physical signs, and symptoms that develop through childhood. Early treatment and support for FAS can help limit the impact on a child's life, but the damage to the brain and body is permanent and cannot be reversed.

Alcohol passes through the placenta, affecting the development of the baby's brain and other organs
Fetal Alcohol Syndrome (FAS) is a lifelong condition that occurs when a person drinks alcohol during pregnancy. It is the most severe condition on the fetal alcohol spectrum disorder (FASD) scale.
When alcohol is consumed during pregnancy, it passes through the placenta via the bloodstream and the umbilical cord to the fetus. The fetus cannot metabolize alcohol in the same way as an adult, so it stays in the body for longer. This can interfere with the normal development of the baby's brain and other organs, causing FAS.
Alcohol can kill cells in different parts of the fetus, disrupting physical development. It also interferes with the development of nerve cells and how they travel to form different parts of the brain. This can lead to nervous system damage, with potential structural and functional impairments. For example, individuals with FAS may have a smaller brain size or alterations in specific brain regions, leading to cognitive and behavioral deficits, motor and coordination problems, and difficulties with learning and memory.
The effects of alcohol on the fetus can vary depending on the stage of pregnancy. During the fourth week of gestation, when the limbs, eyes, and ears are forming, alcohol can affect the development of these structures. By the sixth week, when the teeth and palate are forming, alcohol consumption can impact their development, leading to the facial characteristics of FAS. By the twelfth week, frequent alcohol exposure can negatively impact brain development, affecting cognitive, learning, and behavioral skills. Even beyond the twelfth week, the fetus remains susceptible to the damaging effects of alcohol, which can affect the functioning of the endocrine system in both the fetus and mother.
The risk of FASD increases with the amount of alcohol consumed, the frequency of consumption, and the duration of alcohol consumption during pregnancy. There is no known safe amount of alcohol or safe time to drink during pregnancy.

FAS causes a range of physical, behavioural, and learning problems, as well as distinct facial features
Fetal Alcohol Syndrome (FAS) is the most severe condition on the Fetal Alcohol Spectrum Disorder (FASD) spectrum. FASDs are a group of preventable conditions that can occur when a baby is exposed to alcohol in the womb. Alcohol passes from the mother's blood to the baby through the umbilical cord and placenta.
The physical problems caused by FAS include growth deficiencies, such as low birth weight or height, small head circumference (microcephaly), and small eye openings (blepharophimosis). The eyes and ears are formed during the fourth week of gestation, making them more susceptible to the effects of alcohol. The characteristic facial features of FAS include a smooth connection between the nose and upper lip (called the philtrum), a thin upper lip, and small eyes.
Behavioural problems associated with FAS include challenging behaviours, disruptive behaviour, and impulsivity. Individuals with FAS often have trouble getting along with others and may find it difficult to get a job and live independently as adults.
Learning problems are also common in FAS. People with FAS may experience difficulties with memory, attention span, communication, vision, or hearing. These problems can make it hard for them to succeed in school.

There is no cure for FAS, but early intervention and support can help children reach their full potential
Fetal Alcohol Syndrome (FAS) is a life-long condition that affects people who were exposed to alcohol in the womb. It is the most severe condition on the Fetal Alcohol Spectrum Disorder (FASD) spectrum, which includes partial fetal alcohol syndrome (pFAS), alcohol-related neurodevelopmental disorder (ARND), and neurobehavioral disorder associated with prenatal alcohol exposure (ND-PAE). FASDs are preventable if a developing fetus is not exposed to alcohol.
FAS occurs when a person consumes alcohol during pregnancy, causing the alcohol to pass through the umbilical cord to the fetus. The fetus cannot metabolize alcohol in the same way as an adult, so it stays in the body for longer and can interfere with the normal development of the fetus, particularly the brain and central nervous system. This can result in physical abnormalities, growth deficiencies, distinct facial features, and other problems such as learning, memory, attention span, communication, vision, or hearing difficulties.
There is no cure for FAS, but early intervention and support are crucial for helping children with FAS reach their full potential. While the damage to a child's brain and body from prenatal alcohol exposure cannot be reversed, early diagnosis and support can make a significant difference. Healthcare professionals can assess the child's needs and offer appropriate educational and behavioural strategies to help them develop and thrive.
Pediatric providers often diagnose FAS based on the child's size, specific physical signs, and symptoms that develop through childhood. These may include growth deficiency, abnormal facial features such as a smooth connection between the nose and upper lip, nervous system damage, and behavioural problems. Diagnosing FAS can be challenging, as there is no direct test, and pregnant women may not disclose their complete alcohol intake history.
To support children with FAS, it is recommended to seek help from healthcare professionals, such as doctors or health visitors, who can refer the child to a specialist team for assessment and provide necessary interventions. Support groups for FASD, such as Alcoholics Anonymous (AA) or the National Organisation for FASD, can also provide valuable advice and connect individuals with others in similar situations.

Two drugs, thyroxine and metformin, have shown potential in treating learning and memory deficits caused by fetal alcohol exposure
Fetal Alcohol Syndrome (FAS) is caused when a woman consumes alcohol during her pregnancy, resulting in a wide range of physical, behavioural, and learning problems in the child. Alcohol passes easily through the placenta, the organ that nourishes a baby during pregnancy. Hence, there is no safe amount of alcohol to be consumed during pregnancy. Fetal alcohol exposure can have permanent effects on the brain structure, leading to functional deficits in several aspects of behaviour, including learning and memory.
FAS and other FASDs (Fetal Alcohol Spectrum Disorders) can be prevented by not drinking any alcohol during pregnancy. A woman should refrain from drinking if she is trying to get pregnant or thinks she may be pregnant. If a pregnant woman does drink, it is better for the baby's health if she stops drinking as soon as possible. While there is no cure for FAS or other FASDs, early intervention can help children reach their full potential. Doctors may prescribe medicines to help with related problems, such as attention deficit hyperactivity disorder (ADHD), depression, aggressive behaviour, sleep problems, and anxiety.
Another study on neonatal rat hippocampi found that apelin-13, a peptide, attenuated spatial memory impairment caused by ethanol neurotoxicity through anti-oxidative, anti-apoptosis, and anti-inflammatory mechanisms. While this study did not specifically mention metformin, it provides further evidence that targeting neuroinflammation and apoptosis may be a promising strategy for treating learning and memory deficits associated with fetal alcohol exposure.
