Fetal Alcohol Syndrome (FAS) is a condition that develops in a fetus when a pregnant woman consumes alcohol during her pregnancy. It is the most severe condition on the Fetal Alcohol Spectrum Disorders (FASD) spectrum, which includes Partial Fetal Alcohol Syndrome (pFAS), Alcohol-Related Neurodevelopmental Disorder (ARND), and Neurobehavioral Disorder associated with Prenatal Alcohol Exposure (ND-PAE). FAS is characterised by growth deficiencies, distinct facial features, and other physical factors, in addition to Central Nervous System (CNS) involvement. While FAS is caused specifically by prenatal alcohol exposure, other disorders such as Attention-Deficit/Hyperactivity Disorder (ADHD) and Williams Syndrome share similar behavioural symptoms, which can lead to misdiagnosis.

Fetal Alcohol Syndrome (FAS) shares symptoms with ADHD
Fetal Alcohol Syndrome (FAS) is a condition that develops in a fetus when a pregnant woman consumes alcohol during pregnancy. It is the most severe condition on the fetal alcohol spectrum disorder (FASD) scale. FAS is a lifelong condition with no cure, and even small amounts of alcohol consumed during pregnancy can damage the fetus.
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition with unclear causes, but it stems from changes in brain structure and function during early childhood. While FAS and ADHD are distinct conditions, they share some symptoms and often occur together. Environmental factors, such as prenatal alcohol exposure and adverse childhood experiences, are common to both.
Prenatal alcohol exposure is always the underlying cause of FAS and a possible contributing factor to ADHD. Alcohol consumed during pregnancy passes through the bloodstream to the fetus via the umbilical cord. The fetus's immature metabolism cannot break down alcohol as effectively as an adult, leading to prolonged exposure and interference with normal development, particularly in the brain and central nervous system. This interference can cause changes in the infant's developing brain, resulting in similar symptoms in both FAS and ADHD.
Both conditions can affect areas of the brain essential for executive function, leading to symptoms of varying severity, such as hyperactivity, impulsivity, and inattention. However, intellectual disability is more prevalent in FAS than in ADHD. Additionally, FAS is associated with specific physical growth and trait patterns, whereas ADHD is not linked to any specific physical traits.
The coexistence of FAS and ADHD symptoms may result from multiple factors. For instance, adults with ADHD are more likely to drink alcohol, and pregnant women with ADHD drinking during pregnancy may genetically transmit ADHD to their offspring. While FAS and ADHD share certain symptoms, they are distinct conditions, and no direct cause-and-effect relationship has been established between them.

Partial Fetal Alcohol Syndrome (pFAS) shares symptoms with Williams syndrome
Fetal Alcohol Syndrome (FAS) is a condition that develops in a fetus when a pregnant woman consumes alcohol during pregnancy. Alcohol use during pregnancy can interfere with the baby’s development, causing physical and mental defects. FAS is a life-long condition with no cure, and even small amounts of alcohol consumed during pregnancy can damage the fetus.
Partial Fetal Alcohol Syndrome (pFAS) is a condition where individuals have a known or highly suspected history of prenatal alcohol exposure but do not meet the full diagnostic criteria for FAS. People with pFAS have some of the characteristics of FAS, such as changes to their facial features and growth problems, but do not experience all the symptoms of FAS. pFAS is considered a less severe condition than FAS, falling under the umbrella of Fetal Alcohol Spectrum Disorders (FASDs).
Williams syndrome is mentioned as a disorder that shares some symptoms with FAS and pFAS. However, there is limited information on the specific symptoms of Williams syndrome that overlap with pFAS. It is important to note that diagnosing FASDs can be challenging due to the variety of symptoms and the spectrum of severity.
While FAS and pFAS are caused by prenatal alcohol exposure, Williams syndrome is a genetic disorder caused by a deletion of genetic material from a specific region of chromosome 7. Individuals with Williams syndrome often have distinctive facial features, including a small nose, wide mouth, full cheeks, and a wide smile. They may also experience growth delays, cardiovascular issues, and intellectual disabilities.
In summary, while Partial Fetal Alcohol Syndrome (pFAS) shares some symptoms with Williams syndrome, such as facial features and growth problems, they are distinct conditions with different underlying causes. pFAS is caused by prenatal alcohol exposure and falls under the umbrella of Fetal Alcohol Spectrum Disorders, while Williams syndrome is a genetic disorder resulting from a chromosomal deletion.

Alcohol-related neurodevelopmental disorder (ARND) shares symptoms with intellectual disabilities
Fetal Alcohol Spectrum Disorders (FASDs) refer to a collection of disorders in which a person has been exposed to alcohol before birth. FASDs can have lifelong effects, including problems with behaviour and learning, as well as physical problems. Fetal Alcohol Syndrome (FAS) is the most severe condition on the FASD spectrum.
Alcohol-Related Neurodevelopmental Disorder (ARND) is a type of FASD. It is a neurodevelopmental condition that causes cognitive impairments and problems with learning and behaviour that occur due to prenatal exposure to alcohol. ARND shares symptoms with intellectual disabilities. People with ARND may experience intellectual disabilities and problems with behaviour and learning. They may struggle in school and have difficulties with math, memory, attention, judgment, and impulse control. ARND can also cause emotional dysregulation and social difficulties.
ARND is distinct from other FASDs in that it does not include changes in facial features. However, like other FASDs, it can cause central nervous system problems, such as smaller than normal head size, poor coordination, or problems with attention. ARND can be prevented if a pregnant woman abstains from alcohol consumption.
Diagnosing FASDs can be challenging due to the variety of symptoms and the spectrum of severity. There is no direct medical test, such as a blood test, for FASDs. However, early diagnosis and intervention are crucial for managing ARND symptoms and preventing secondary conditions, such as mental health issues. Educational and behavioural therapies, as well as social services, can provide valuable support to individuals with ARND and their families.
It is important to note that FASDs are preventable if a developing fetus is not exposed to alcohol. Complete abstinence from alcohol during pregnancy is essential to mitigate the risks associated with FASDs, including ARND.

Neurobehavioral disorder associated with prenatal alcohol exposure (ND-PAE) shares symptoms with intellectual disabilities
Fetal Alcohol Spectrum Disorders (FASDs) are a group of preventable conditions that occur in individuals exposed to alcohol in utero. FASDs can have lifelong effects, including problems with behaviour, learning, and physical development. Fetal Alcohol Syndrome (FAS) is the most severe condition on the FASD spectrum.
Neurobehavioral Disorder Associated with Prenatal Alcohol Exposure (ND-PAE) is a type of FASD. ND-PAE was introduced into the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) in 2013 as a "Condition for Further Study" and a specifier for intellectual disability. ND-PAE can cause psychological, cognitive, behavioural, and physical symptoms, although the symptoms vary depending on factors such as the amount of alcohol exposure.
A child with ND-PAE will have problems in three areas: thinking and memory, behaviour, and day-to-day living. Specifically, a child with ND-PAE may have trouble planning or may forget material they have already learned. They may also experience severe tantrums, mood issues, and difficulty shifting attention from one task to another. Finally, they may have trouble with day-to-day tasks such as bathing and dressing for the weather.
ND-PAE shares symptoms with intellectual disabilities. For example, people with ND-PAE may experience problems with learning, memory, attention, and communication. They may also have a hard time in school and have trouble getting along with others. These symptoms overlap with those of intellectual disabilities.
Diagnosing ND-PAE can be challenging because there is no medical test, such as a blood test, for this condition. Additionally, the disorder does not always present the same way in all children due to differences in timing and amount of prenatal alcohol exposure, genetic predispositions, and postnatal environment.

Alcohol-related birth defects (ARBD) shares symptoms with physical birth defects
Alcohol-related birth defects (ARBD) are physical birth defects that occur when a developing foetus is exposed to alcohol during pregnancy. ARBDs are a type of fetal alcohol spectrum disorder (FASD) and are considered the most severe condition within this group.
ARBDs are characterised by abnormal changes to parts of the body, including the heart, eyes, skeletal system, ears, and kidneys. These changes can affect how a child's body develops and functions, leading to physical symptoms such as muscle aches and movement difficulties. Unlike other forms of FASDs, ARBDs do not cause neurological symptoms. However, they can still impact a child's physical growth and development, resulting in differences in physical appearance and function.
The symptoms of ARBDs can vary in severity and may be present from birth or become apparent later in a child's life. Early diagnosis and intervention are crucial for improving outcomes for children with ARBDs. Treatment options may include physical therapy, assistive devices, and occupational therapy to help individuals adapt to their daily routines and improve their quality of life.
It is important to note that ARBDs share symptoms with other physical birth defects. For example, conditions such as partial fetal alcohol syndrome (pFAS) also exhibit changes to facial features and growth problems. Additionally, neurobehavioral disorder associated with prenatal alcohol exposure (ND-PAE) can result in behavioural issues, difficulty with daily tasks, and problems with thinking and memory, which may overlap with the physical symptoms of ARBDs.
The diagnosis of ARBDs can be challenging, and there is no single medical test, such as a blood test, to confirm the condition. Healthcare providers rely on physical examinations, growth abnormalities, and evidence of alcohol consumption during pregnancy to make a diagnosis. The treatment and management of ARBDs are tailored to each individual, addressing their specific needs and symptoms as they grow and develop.

Frequently asked questions
Yes, fetal alcohol syndrome (FAS) shares symptoms with other diseases. FAS is a condition that develops in a fetus when a pregnant 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). FAS is characterized by growth deficiencies, distinct facial features, central nervous system (CNS) problems, and other physical and neurodevelopmental issues. Other disorders that share some of these symptoms include attention-deficit/hyperactivity disorder (ADHD), Williams syndrome, and depression.
The symptoms of fetal alcohol syndrome can vary among individuals, ranging from mild to severe. Common symptoms include abnormal facial features, such as small eyes, a thin upper lip, and a smooth philtrum (groove between the nose and upper lip). Other symptoms may include growth deficiencies, low birth weight, small head circumference, heart defects, bone and kidney problems, vision and hearing issues, seizures, learning disabilities, poor balance and coordination, delayed development, and behavioral problems.
The Centers for Disease Control (CDC) estimates that there are less than 2 cases of FAS out of every 1,000 live births in the United States. However, when considering the broader spectrum of FASDs, the frequency may be higher, ranging from 1 to 5 out of every 100 children in the U.S. and Western Europe. According to a National Institute on Alcohol Abuse and Alcoholism (NIAAA)-supported study, approximately 1% to 5% of first graders in the U.S. have FASD.
