Altered neuronal and glial cell proliferation and migration 29,30,32, including disrupted oligodendrocyte maturation, are thought to contribute to dysfunctional brain architecture and connectivity in PAE-affected organisms. In addition, PAE is known to impact placental health 33, to affect iron regulation in the developing fetal brain 34, and to disrupt maternal–fetal iron homeostasis 35, which may, in turn, contribute to neurodevelopmental abnormalities in areas such as the hippocampus. Notably, iron deficiency affects gray matter development, including hippocampal integrity and dendrite complexity 36,37, as well as white matter development, such as myelination 38. Even in patients who clearly have met diagnostic criteria, referral allows complete assessment for an individualized management plan (Table 34). PAE after 8 weeks of gestation affects neurogenesis, differentiation of neural precursor cells, neuronal migration, pathfinding, synaptogenesis and axon myelination72,85,86 but does not cause sentinel craniofacial dysmorphology or major organ defects. Thus, PAE after major organogenesis may result in a FASD phenotype with neurodevelopmental disorder but without physical alterations, making diagnosis difficult80.
- A doctor or health visitor will need to know if your child was exposed to alcohol during pregnancy to help make a diagnosis of FASD.
- It’s possible that even small amounts of alcohol consumed during pregnancy can damage your developing fetus.
- Furthermore, mothers of children with FASD have a 44.8-fold increased mortality risk compared with mothers of children without FASD274.
- When researchers look at the whole spectrum of disorders (FASD), the frequency may be as high as 1 to 5 out of every 100 kids in the U.S. and Western Europe.

The full picture of FAS drunken baby syndrome usually occurs in babies born to alcoholic mothers, or those who drink more than four to five drinks each day. Children with FASD are nutritionally and socially vulnerable and may benefit from nutritional education and support. To diagnose someone with FAS, the doctor must determine that they have abnormal facial features, slower than normal growth, and central nervous system problems.
Fetal Alcohol Syndrome FAQs
If you’re a light or social drinker, don’t drink if you think you might become pregnant anytime soon. Remember, the effects of alcohol can make a mark during the first few weeks of a pregnancy. Visit these blogs for more tips and information about fetal alcohol syndrome. Prenatal exposure to alcohol can lead to serious conditions such as fetal alcohol syndrome disorders (FASDs). The most severe type of FASD — fetal alcohol syndrome — may cause distinctive facial features. Sometimes this can result in mental and physical problems in the baby, called fetal alcohol spectrum disorder (FASD).
Fetal Alcohol Spectrum Disorder Overview
Exposure of astrocytes to alcohol and metabolism of alcohol by cytochrome P450 2E1 result in the production of damaging reactive oxygen species84,126. Alcohol is metabolized to acetaldehyde, a toxin that causes DNA damage, epigenetic gene regulation, mitochondrial and proteosome dysfunction, and altered cellular metabolism127,128,129. Metabolism of acetaldehyde to acetate and then to acetyl-CoA modifies gene expression in the brain via increased histone acetylation121 (Fig. 5). This Primer presents the epidemiology of FASD and the latest understanding of its pathophysiology as well as approaches to diagnosis, screening and prevention. The Primer also describes outcomes across the lifespan, management and quality of life (QOL) of people living with FASD, and highlights important areas for future research and clinical practice. Alcohol was not viewed as dangerous for pregnant people until 1973 when the diagnosis of FAS was first implemented.
Fetal Alcohol Syndrome Prevention
- The findings are of public health significance, since it’s estimated that more than 1 million babies born annually in the United States have been exposed to at least one of these things in utero.
- They might present as hyperactivity, lack of coordination or focus, or learning disabilities.
- Although FAS is an incurable lifelong condition that is underdiagnosed, treatment can improve its symptoms.
- Mitigating stigma is vital while addressing the structural and systemic factors that promote prenatal alcohol consumption35.
However, it’s important to note that there is no treatment for life-long birth defects and retardation. Children with FASD are at increased risk of physical and sexual violence, with 61% experiencing physical or sexual abuse or witnessing domestic violence by 12 years of age.29,39 Sexual abuse should be considered in children who present with inappropriate sexual behaviors. You can avoid fetal alcohol syndrome by not drinking alcohol during pregnancy. If you’re a woman with a drinking problem who wants to get pregnant, seek help from a doctor.
- Prenatal alcohol exposure and central nervous system (CNS) involvement are factors common to the disorders encompassing FASD.
- However, the Food and Drug Administration (FDA) did not make a public awareness announcement about the side effects of alcohol use during pregnancy until 1977.
- This means that some people with mild symptoms of FASD might never be diagnosed.
- You can also find your nearest alcohol support services or read advice on cutting down your drinking and alcohol in pregnancy.
- Preclinical trials suggest that choline supplements improve cognitive deficits following PAE but clinical data are limited257.
Research shows that binge drinking and heavy drinking during pregnancy put a developing baby at the greatest risk for severe problems.4 However, even lesser amounts can cause harm.5,6 In fact, there is no known safe amount of alcohol consumption during pregnancy. If you think there could be a problem, ask your healthcare provider for a referral to a specialist (someone who knows about FASDs). Specialists could be a developmental pediatrician, child psychologist, or clinical geneticist. In some cities, there are clinics whose staff members have special training in diagnosing and treating children with FASDs. To find healthcare providers and clinics in your area, contact FASD United’s (formerly NOFAS) Family Navigator program which provides individuals living with FASDs and their family members and caregivers with expert, confidential support and referrals. A more recent article on fetal alcohol syndrome and fetal alcohol spectrum disorders is available.
Early diagnosis and intervention are important and helpful for children with fetal alcohol syndrome to prevent possible behavioral disorders and help with learning. Fetal alcohol syndrome (FAS) is the most severe form of fetal alcohol spectrum disorder, a range of conditions caused by exposure to alcohol in the womb. FAS symptoms include distinctive facial features, lower-than-average height and weight, and problems with brain and nervous system development. There is no single test for fetal alcohol syndrome (a lifelong condition), but early detection and treatment can greatly improve the lives of children with FAS. Research conducted to date highlights important avenues for future investigation to further elucidate mechanisms by which choline supplementation in the prenatal and postnatal periods may improve long-term neurodevelopmental outcomes for individuals affected by PAE. Future studies might evaluate the effects of different doses/duration of choline supplementation on specific biological outcomes, such as DNA methylation.
Alcohol’s Effects on the Developing Brain and Cognition
Because no amount of alcohol is proven safe, women should stop drinking immediately if pregnancy is suspected. To diagnose fetal alcohol syndrome, doctors look for unusual facial features, lower-than-average height and weight, small head size, problems with attention and hyperactivity, and poor coordination. They also try to find out whether the mother drank while they were pregnant and if so, how much. The Outpatient Psychiatry Service at Boston Children’s Hospital works with children and adolescents to determine if psychoactive medication would be an effective tool in their psychiatric treatment.
- Visit the NIAAA Alcohol Treatment Navigator® to learn more about evidence-based treatments for alcohol-related problems.
- In response, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) has convened an international consensus committee to analyse data derived from existing diagnostic systems and develop a consensus research classification for FASD290.
- Brain growth in the fetus takes place throughout pregnancy, so stopping alcohol consumption as soon as possible is always best.
- Nevertheless, they suggest the potential to modify developmental trajectories by addressing postnatal environmental exposures and opportunities.
- Ongoing care in a supportive pediatric home is an important component to achieving health and wellbeing for any child with an FASD and their family.
- Evidence of CNS involvement can be structural (e.g., small brain size, alterations in specific brain regions) or functional (e.g., cognitive and behavioral deficits, motor and coordination problems).
- In the absence of characteristic facial findings, the diagnosis of FASD still should be considered in children with growth problems, CNS abnormalities, and a history of prenatal alcohol exposure.
Most children with FASD have significant problems with executive function and self-regulation189. The ALERT programme, a 12-week manualized approach using sensory integration and cognitive behavioural strategies, aims to help children regulate their behaviour and address sensory challenges246 in a home environment247,248 but is less effective when delivered in schools249. ALERT programme training is available online but requires adaptation to the family and community context249.
