Fetal Alcohol Syndrome (FAS) is a disorder caused by prenatal alcohol exposure in which individuals are born with physical and mental abnormalities. It is the most severe form of Fetal Alcohol Spectrum Disorders (FASDs), a range of physical, cognitive, and behavioral effects caused by prenatal alcohol exposure. While FAS and other FASDs are entirely preventable, they are among the leading causes of intellectual disability and birth defects in the United States (Centers for Disease Control and Prevention [CDC], 2020).
FAS is characterized by a distinctive set of facial features, growth deficiencies, and central nervous system (CNS) problems that can lead to difficulties with learning, memory, and problem-solving (Kable & Coles, 2011). The facial features associated with FAS include small head circumference, thin upper lip, short nose, low nasal bridge, and small eyes (CDC, 2020). Additionally, individuals with FAS may have difficulty with language, memory, abstract thinking, and attention, as well as physical problems such as heart defects, hearing problems, and vision problems (Kable & Coles, 2011).
The diagnosis of FAS requires that there be an evidence of prenatal alcohol exposure, physical signs of FAS, and central nervous system problems (CDC, 2020). The diagnosis is made by a multidisciplinary team of health professionals, such as a pediatrician, developmental pediatrician, child psychologist, child psychiatrist, or other specialist (Kable & Coles, 2011). It is important to note that there is no cure for FAS, but there are interventions and treatments that can help individuals manage the symptoms and improve their quality of life (CDC, 2020).
The first step in preventing FAS is abstaining from alcohol during pregnancy (CDC, 2020). This is especially important during the first trimester of pregnancy when the organs and body systems of the developing fetus are most vulnerable to the negative effects of alcohol (Kable & Coles, 2011). Additionally, women of childbearing age should be aware of the risks associated with drinking alcohol during pregnancy and should be educated about the signs and symptoms of FAS (CDC, 2020).
In conclusion, Fetal Alcohol Syndrome (FAS) is a disorder caused by prenatal alcohol exposure that can cause physical and cognitive problems in the child. FAS is entirely preventable, making it imperative that women of childbearing age are educated about the risks and abstain from drinking alcohol during pregnancy.
