Fetal Alcohol Syndrome (FAS) is a condition that occurs when a person is exposed to alcohol during gestation, causing a range of physical and neurodevelopmental deficits. While it is possible that people in the past had FAS, the term and diagnostic criteria for this condition were first established in 1973 by Jones and Smith, who described the consistent pattern of malformations among children born to mothers with significant prenatal alcohol intake. This publication was met with skepticism due to the prevalent view that alcohol was safe during pregnancy. As a result, it is likely that many cases of FAS in the past were undiagnosed or misdiagnosed, contributing to a perceived absence of the condition.

The term fetal alcohol syndrome (FAS) was only first published in 1973
The term Fetal Alcohol Syndrome (FAS) was first published in 1973 in an article in the British medical journal The Lancet. The article was written by a group of pediatricians and psychiatrists at the University of Washington Medical School, who defined the morphological defects and developmental delays that could affect children born to alcoholic mothers. They also provided diagnostic criteria for the disorder and described in detail the consistent pattern of malformations among children whose mothers consumed significant amounts of alcohol during pregnancy.
Prior to this publication, the existing prevalent view was that alcohol consumption was safe during pregnancy. As a result, there was much skepticism surrounding the proposed teratogenicity of alcohol and whether it was indeed the agent underlying this newly named syndrome. However, the 1973 publication was followed by additional research that provided further clarity and supported the link between prenatal alcohol exposure and FAS.
FAS is a condition that occurs when a person drinks any alcohol during pregnancy, including wine, beer, hard cider, and liquor. It can lead to a range of symptoms, such as abnormal facial features (e.g., a smooth ridge between the nose and upper lip, a thin upper lip, and small eyes), low body weight, short height, sleep and sucking difficulties, small head size, and vision or hearing problems. These symptoms will be with the person throughout their entire life, and secondary effects can occur over time, particularly if the condition is not treated during childhood.
It is important to note that there are different forms of FAS, including partial fetal alcohol syndrome (pFAS), which refers to individuals with a history of prenatal alcohol exposure who exhibit some characteristics of FAS but do not meet the full criteria for a diagnosis. FASD, or fetal alcohol spectrum disorder, is an umbrella term for a group of conditions that can occur due to alcohol exposure during gestation, with FAS being the most severe and visually apparent subtype.

FAS is caused by alcohol consumption during pregnancy, which was less common in the past
Fetal Alcohol Syndrome (FAS) is a condition that occurs when a person consumes alcohol during pregnancy. It can cause a range of physical and neurodevelopmental issues in the child, including abnormal facial features, low body weight, vision and hearing problems, and cognitive and emotional deficiencies. The condition was first identified and named in 1973, when a group of medical professionals at the University of Washington Medical School published an article in the British medical journal The Lancet, detailing the effects of prenatal alcohol exposure.
Prior to this discovery, alcohol consumption during pregnancy was not recognised as a teratogenic agent, and it was widely believed that alcohol was safe for pregnant women to consume. This misconception likely contributed to underreporting and misdiagnosis of FAS in the past. However, it is important to note that alcohol consumption during pregnancy has always carried the risk of FAS, even before it was formally recognised and named.
The prevalence of alcohol consumption during pregnancy in the past is difficult to ascertain. However, it is reasonable to assume that as awareness of the dangers of alcohol during pregnancy has increased, more women have chosen to abstain from alcohol while pregnant. This could be a contributing factor to the perceived absence of FAS in historical records.
Social and cultural norms around alcohol consumption may also have influenced drinking habits during pregnancy in the past. In some societies, alcohol was predominantly consumed on social occasions or in ceremonial contexts, rather than regularly or privately. This could have resulted in lower overall consumption, including during pregnancy.
Additionally, diagnostic capabilities and medical understanding have improved over time. The criteria for diagnosing FAS have become more refined, and the distinction between full FAS and partial FAS (pFAS) has been established. This has likely led to more accurate identification and diagnosis of FAS and its associated disorders in recent times.
In conclusion, while FAS is caused by alcohol consumption during pregnancy, which may have been less common or recognised in the past, the absence of historical records does not necessarily indicate a lack of FAS. Improved medical understanding, diagnostic criteria, and changing social norms around alcohol consumption may all contribute to the perceived absence of FAS in the past.

The effects of FAS can vary, and mild cases may go undiagnosed
Fetal Alcohol Syndrome (FAS) is a condition that occurs when a person drinks alcohol during pregnancy. The term was first published in 1973 in the British medical journal The Lancet, and it has since been recognised as a leading cause of preventable mental disability in Canada and the United States. The symptoms of FAS can vary, and mild cases may go undiagnosed.
The effects of FAS can be both physical and neurodevelopmental. Physical symptoms may include abnormal facial features, such as a smooth ridge between the nose and upper lip, a thin upper lip, small eyes, and a small head size. Individuals with FAS may also experience low body weight, short height, sleep and sucking difficulties, and vision or hearing problems. These physical abnormalities are caused by alcohol consumption during the sixth week of gestation, when the teeth and palate are forming.
The neurodevelopmental effects of FAS can include cognitive and emotional deficiencies, such as problems with memory, learning, attention, and social communication. These impairments may develop over time, and secondary effects can occur later in life, particularly if the condition is not treated during childhood.
Partial fetal alcohol syndrome (pFAS) refers to individuals who have some characteristics of FAS but do not meet the full diagnostic criteria. People with pFAS may have alcohol-related physical and neurodevelopmental deficits, and changes to their facial features. The diagnosis of FAS requires a positive finding on all four diagnostic features, which include the physical and neurodevelopmental symptoms mentioned above.
The frequency of FAS may be higher than reported due to under-diagnosis and misdiagnosis. The Centers for Disease Control (CDC) estimates less than 2 cases of FAS in every 1,000 live births in the United States when looking specifically at FAS. However, when considering the broader spectrum of fetal alcohol spectrum disorders (FASD), the frequency may be as high as 1 to 5 out of every 100 children in the U.S. and Western Europe. FASD affects 1 in 20 Americans, and the symptoms can vary widely in severity.

Partial fetal alcohol syndrome (pFAS) refers to those with some FAS characteristics but not all symptoms
Fetal Alcohol Syndrome (FAS) is a permanent condition that occurs when a pregnant woman consumes alcohol. Alcohol use during pregnancy can interfere with the baby's development, causing physical and mental defects. FAS is the most severe condition within a group of conditions called fetal alcohol spectrum disorders (FASDs). FASDs are a group of preventable conditions that can occur in a person exposed to alcohol before birth. FASDs affect 1 in 20 Americans but are highly misdiagnosed and underdiagnosed.
Partial fetal alcohol syndrome (pFAS) refers to individuals with a known or highly suspected history of prenatal alcohol exposure who have alcohol-related physical and neurodevelopmental deficits that do not meet the full criteria for FAS. People with pFAS have some of the characteristics of FAS (such as changes to their facial features) but do not experience all the symptoms. pFAS was previously known as atypical FAS in the 1997 edition of the "4-Digit Diagnostic Code". Those with pFAS may lack growth deficiency or the complete facial stigmata, but central nervous system damage is present at the same level as FAS.
The signs and symptoms of FAS can vary. One person might have only a few, while another person could experience all of them. FAS includes mental and physical challenges. An individual with FAS may have noticeable changes to their face and limbs, as well as delays in the way their body develops over time. There can also be mental and emotional challenges throughout the person's life that can impact their social life, education, and work.
FASDs can have lifelong effects, including problems with behavior and learning, as well as physical problems. Individuals with FASDs can experience secondary effects over time, particularly if they are not treated for the condition in childhood. FASDs are preventable if a developing baby is not exposed to alcohol.

FAS was previously attributed to other factors due to skepticism about alcohol's effects
Fetal Alcohol Syndrome (FAS) is a condition that arises when a person consumes alcohol during pregnancy. The syndrome results in fetal growth deficiencies, brain development issues, and central nervous system problems, which manifest as cognitive and emotional deficiencies, including problems with memory, learning, attention, and social communication. FAS can also cause malformations of the face, such as a smooth ridge between the nose and upper lip, a thin upper lip, and small eyes.
The term Fetal Alcohol Syndrome (FAS) was first published in 1973 in the British medical journal The Lancet. In this article, a group of pediatricians and psychiatrists at the University of Washington Medical School helped define the morphological defects and developmental delays observed in children born to alcoholic mothers. However, despite this publication, there was initial skepticism about the teratogenic effects of prenatal alcohol exposure. The prevailing view at the time was that alcohol consumption during pregnancy was safe, which led to doubt regarding the proposed teratogenicity of alcohol and whether it was the underlying cause of the newly identified syndrome.
Subsequently, in 1974, Jones et al. published a study that adjusted for confounding factors, clarifying that the patterns observed in the 1973 study were indeed due to prenatal alcohol exposure and not solely attributable to socioeconomic factors. This research provided further evidence to support the link between prenatal alcohol exposure and the consistent pattern of malformations and developmental issues observed in children with FAS.
Despite the growing body of research linking prenatal alcohol exposure to FAS, the syndrome may have been historically attributed to other factors due to skepticism about alcohol's effects. This skepticism could have influenced the perception of FAS and led to alternative explanations for the symptoms observed in affected individuals. Additionally, the diagnosis of FAS requires the presence of specific criteria, and partial fetal alcohol syndrome (pFAS) may have been diagnosed in cases where all the criteria for FAS were not met. pFAS individuals have some characteristics of FAS, such as facial changes, but do not exhibit the full range of symptoms.
Furthermore, FASD, which includes FAS and pFAS, is highly misdiagnosed and underdiagnosed, with an estimated prevalence of 1 in 20 Americans affected. The symptoms of FAS can vary in severity and may be attributed to other factors or disorders with overlapping features. Additionally, the social and economic consequences of acknowledging FAS may have played a role in its attribution to other factors. Acknowledging the syndrome's presence would have significant implications for the alcohol industry, public health policies, and social perceptions of alcohol consumption during pregnancy.
