What is the most serious type of Fetal Alcohol Spectrum Disorders (FASD)?

Fetal Alcohol Syndrome (FAS) is the most serious and comprehensive type of Fetal Alcohol Spectrum Disorders (FASDs). This syndrome is part of a group of conditions that can occur in a child who was exposed to alcohol before birth [1]. Fetal alcohol spectrum disorders can range from mild to severe, and they affect each person in different ways [1].

What is Fetal Alcohol Syndrome (FAS)?

Fetal Alcohol Syndrome (FAS) represents the most complex end of the fetal alcohol spectrum disorders [1]. People with FAS experience central nervous system problems, distinctive facial features, and growth issues [1]. These problems include difficulties with learning, memory, attention span, communication, vision, or hearing [1]. They often face difficulty in school and interacting with others [1].

Other Types of Fetal Alcohol Spectrum Disorders

In addition to Fetal Alcohol Syndrome (FAS), FASDs include several other conditions, including [1]:

• Partial Fetal Alcohol Syndrome (pFAS): This occurs when a person does not meet all the diagnostic criteria for full Fetal Alcohol Syndrome, but has a history of prenatal alcohol exposure and some facial features, as well as a growth problem or central nervous system abnormalities [1].
• Alcohol-Related Neurodevelopmental Disorder (ARND): People with this disorder may suffer from intellectual disabilities and problems with behavior and learning [1]. They may perform poorly in school and have difficulties with mathematics, memory, attention, judgment, and poor impulse control [1].
• Alcohol-Related Birth Defects (ARBD): People with these defects may have problems with the heart, kidneys, bones, or hearing [1].
• Neurobehavioral Disorder Associated with Prenatal Alcohol Exposure (ND-PAE): A child or youth with this disorder experiences problems in three areas: thinking and memory, behavioral problems, and difficulty with daily living skills [1].

Prevention of Fetal Alcohol Spectrum Disorders

Fetal alcohol spectrum disorders are entirely preventable if the developing fetus is not exposed to alcohol [1]. There is no known safe amount of alcohol that can be consumed during pregnancy or when trying to conceive [1]. Alcohol can cause problems for the developing fetus throughout the entire pregnancy, including before a woman knows she is pregnant [1]. All types of alcohol are equally harmful, including all types of wine and beer [1].

To prevent these disorders, a woman should avoid alcohol if she is pregnant or might be pregnant [1]. This is because a woman may be pregnant and not know it for up to 4 to 6 weeks [1]. It is never too late to stop drinking alcohol during pregnancy; because brain development occurs throughout pregnancy, stopping alcohol consumption will improve the child's health and well-being [1].

Important Next Steps

If you are pregnant or trying to conceive and cannot stop drinking, it is important to get help [3]. A healthcare provider can recommend counseling and treatment programs [3].
