Often, having a stable and supportive home can help children with FAS avoid developing mental and emotional difficulties as they get older. There isn’t a direct test for FAS and pregnant people may not give a complete history of all alcohol intake during pregnancy. The more you drink while pregnant, the greater the risk to your unborn baby. Your baby’s brain, heart and blood vessels begin to develop in the early weeks of pregnancy, before you may know you’re pregnant. Deficiencies in the basal ganglia have also been noted in subjects with FASD (Riley and McGee, 2005). Significant volume reductions are observed in the caudate of subjects with FASD (Archibald et al., 2001).
- This exposure typically occurs when a pregnant person drinks alcohol, and it enters the fetus’s bloodstream through the umbilical cord.
- Partial fetal alcohol syndrome (pFAS) may be diagnosed if a child has at least two of the typical facial features and a mix, but not all, of the required criteria for FAS.
- There’s no cure for FASDs, but early treatment can help your child thrive.
Why is fetal alcohol syndrome a concern?
Other animal models have also been developed in Drosphila, zebrafish, guinea pigs and avian embryos (Fabregues et al., 1985; Cudd, 2005; Smith, 2008; McClure et al., 2011; Cole et al., 2012). Animal models of FASD target and expose animals to blood alcohol concentrations observed in humans during specific developmental hallmarks and then examine subsequent behavioral and structural changes induced by alcohol exposure (Table 1). These studies recapitulate several of the behavioral deficits observed in subjects with FASD in these animal models, with impairments observed in attention, inhibition, motor tasks, learning and social interactions. A full review of the behavioral consequences of alcohol in animal models of FASD was recently published (Patten et al., 2014). 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.

You can share your concerns and ask for a referral to a doctor who specializes in FASDs for further support. The CDC explains that it’s difficult to know the true prevalence of FASDs. They estimate that around 1 baby in every 1,000 born in the United States may be affected. Other groups, like the National Institutes of Health, have higher estimates — 1 to 5 children per every 100.
- Once the condition has been diagnosed, a team of healthcare professionals can assess your child’s needs and offer appropriate educational and behavioural strategies.
- Alcohol withdrawal may begin within a few hours after birth, and symptoms may last up to 18 months.
- The protective effect of early FASD diagnosis can reduce the risk of additional disabilities and mitigate lifelong consequences.
- Early identification can improve the outcome for children with FAS and raise their quality of life.
For people trying to get pregnant
The AUDIT screening questionnaire can be incorporated into the general patient information and history questionnaire used for patient intake and updates. Individuals tend to respond more openly to alcohol and drug use questions when embedded into an intake form rather than within a face to face interview. Screening need only be done for first time obstetric patients and women presenting for their annual gynecologic office visit.
The Centers for Disease Control and Prevention (CDC) reports that every American state or territory has early intervention programs available to support babies and young children with developmental delays and learning disabilities. It can cause problems with learning, behavior, and mental and physical health. Less than 4% of the U.S. population are alcohol dependent or alcoholic to the extent of requiring medical treatment and intensive behavioral counseling.
What causes fetal alcohol syndrome and other fetal alcohol spectrum disorders?
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. In some cases, your healthcare provider might be able to diagnose a child with fetal alcohol syndrome at birth based on small size and specific physical appearance. However, diagnosis of fetal alcohol spectrum disorders can be difficult. FASD may present in childhood or early adulthood with mild social or intellectual concerns, or it can present with birth defects and growth problems during pregnancy. Fetal alcohol spectrum disorders (FASDs) are a group of conditions that can occur in a person exposed to alcohol before drunken baby syndrome birth. These conditions can affect each person in different ways and can range from mild to severe.
Fetal Alcohol Spectrum Disorders FAQs
As seen with other aspects of FASD, individuals afflicted with neurobehavioral deficits do not necessarily possess the characteristic facial features. However, those with prototypical FAS features generally exhibit more severe neurobehavioral deficits (Mattson and Riley, 1998). Approximately 25% of individuals with FAS fit the criteria for intellectual disability (an IQ lower than 70; Streissguth et al., 1997), making FAS the most common preventable cause of intellectual disability in the general population (Abel and Sokol, 1987). Given the range of cognitive impairments described above, it is not surprising that prenatal alcohol exposure is coincident with reduced academic performance and an increased frequency of learning disabilities (Howell et al., 2006). Indeed, attention deficit hyperactivity disorder (ADHD) is often diagnosed in FASD individuals with concordance rates ranging from 65–95% (Coles et al., 2002; Fryer et al., 2007; Rasmussen et al., 2010).
Preventing fetal alcohol syndrome
Astrocyte-specific expression of serum response factor in a ferret model of early alcohol exposure reverses alcohol-induced reductions in ocular dominance plasticity (Paul and Medina, 2012). The formation of the corpus callosum is strongly affected by prenatal alcohol exposure (Riley and McGee, 2005; Norman et al., 2009; Lebel et al., 2011). Attempts to identify the degree of damage in living subjects with FASD have been carried out with magnetic resonance imaging (MRI). These reports indicate that individuals with FASD exhibit a reduction in the cranial vault as well as a corresponding decrease in the overall size of the brain (Mattson et al., 1992; Archibald et al., 2001). More recent reports indicate reduced gyrification of the cortex (Infante et al., 2015) and a reduction in the surface area of the anterior cingulate cortex (Migliorini et al., 2015) among adolescents with heavy prenatal alcohol exposure. Reduced activation of some cerebellar areas during rhythmic vs. non-rhythmic finger tapping (du Plessis et al., 2014) and global reductions in gray matter (Soh et al., 2015) are observed in subjects with FAS and FASD.
