Although the intensity, duration, and timing of prenatal ethanol exposure can have dramatic effects on the manifestation of these abnormalities, the general trend is that as exposure to ethanol increases, the expression of abnormal facial traits increases. Diagnostic characteristics typical of children with FAS include smaller eye openings (palpebral fissures, the region between the upper and lower eyelid), at times accompanied by folds of skin (epicanthal folds) at the corners of the eyes that stretch the upper lids taut and create a more oval shape. A general shortening of the nose occurs, often accompanied by a lowered nasal bridge.

What is fetal alcohol syndrome (FAS)?

• Using alcohol during pregnancy is the leading cause of preventable birth defects, developmental disabilities and learning disabilities.
• Thus, elucidating not just the cell-specific effects of alcohol, but also the cell-cell interactions that occur is necessary to fully understand and effectively treat abnormal brain development.
• In 1973, responding to Jones and Smith’s publication on the original syndrome FAS, NIAAA initiated several epidemiological and animal studies on prenatal alcohol exposure.

Dependence and addiction to alcohol in the mother also cause the fetus to become addicted. But since the alcohol is no longer available, the baby’s central nervous system becomes over stimulated, causing symptoms of withdrawal. Alcohol withdrawal may begin within a few hours after birth, and symptoms may last up to 18 months. Alcohol in the mother’s blood passes to the baby through the umbilical cord.

Can you prevent FASDs?

The Navigator helps adults find alcohol treatment for themselves or an adult loved one. In the womb, a baby doesn’t have a fully developed liver drunken baby syndrome that can process or break down alcohol, so it can easily get to and damage the baby’s organs. If you suspect your child may already have an FASD, a doctor can also help you find the support you need for your child’s development and your own well-being. It may be difficult to diagnose FASDs because there’s no single test to make a diagnosis. Instead, you or a doctor may observe a cluster of symptoms in your child that suggests they have an FASD.

FASD-related Brochures and Fact Sheets

Additionally, the range and aetiology of adult outcomes require clarification to inform assessment and prognosis in FASD291. A research initiative for elderly people with FASD is urgently needed as there is virtually no information about the diagnostic criteria or neuropsychological outcomes of FASD in this age group. Fetal alcohol spectrum disorders (FASDs) are a group of conditions that can occur in a person who was exposed to alcohol before birth. A linear relationship exists between ethanol exposure and the severity of expression of ethanol-induced defects.

Abstaining From Alcohol to Prevent Fetal Alcohol Syndrome

Significant volume reductions are observed in the caudate of subjects with FASD (Archibald et al., 2001). Recent studies also suggest asymmetric formation of the caudate among subjects with either one trimester or all three trimesters of alcohol exposure in utero (Willford et al., 2010). Because many people do not know they are pregnant during those first few weeks, the risk of FAS increases if you drink alcohol and have unprotected sex. However, most studies have not researched FAS symptoms in people over the age of 30. The best prevention method is to avoid alcohol use when you’re trying to become pregnant, when you suspect you may be pregnant, or when you know you’re pregnant. The outlook will be individual for each child, what type of FASD they have, and what treatments/therapies they have access to.

In humans, most myelination takes place during the first 20 years of postnatal life (Lebel et al., 2008). While the bulk of myelination occurs in relatively early postnatal life, it is now clear that myelination continues throughout life (Bartzokis et al., 2012; Young et al., 2013). Coinciding with their later development, oligodendrocytes are the final cells of the CNS to mature.

• Pharmacological interventions for FASD are widely used and include medications, such as cognitive enhancers, to treat core impairments and medications to treat comorbidities, including ADHD, anxiety, and arousal or sleep disorders253.
• Prenatal exposure to ethanol affects a developing embryo as early as the third week after fertilization, with midline facial abnormalities the first developmental defect observed.
• Public-health authorities agree that the alcohol industry should have no involvement in the development of public-health policies owing to their inherent conflict of interest218,219.
• However, the only way to prevent FAS is to avoid drinking beverages containing alcohol during pregnancy.
• Alcohol stimulates the production of reactive oxygen species in microglia and astrocytes, leading to neuronal apoptosis84.

How are fetal alcohol spectrum disorders diagnosed?

A single episode of binge drinking, especially during the first few weeks of pregnancy, can lead to FAS. Having four or more drinks within two hours is considered a single binge-drinking episode for females. That said, any amount of alcohol may increase the risk of a baby developing an FASD.
