Fetal Alcohol Syndrome (FAS) is a clinical diagnosis based on a documented history of prenatal alcohol exposure combined with specific physical features, growth deficits, and neurodevelopmental impairments. Because there is no single medical test to confirm Fetal Alcohol Syndrome, diagnosis requires a multidisciplinary evaluation by specialists who can distinguish these patterns from other genetic or developmental conditions. What are the primary clinical features of Fetal Alcohol Syndrome? Clinicians look for a specific triad of findings when evaluating an individual for Fetal Alcohol Syndrome.

Clinicians look for a specific triad of findings when evaluating an individual for Fetal Alcohol Syndrome. These include: 1) characteristic facial features (such as a smooth philtrum, thin upper lip, and short palpebral fissures), 2) growth retardation (height or weight below the 10th percentile), and 3) central nervous system abnormalities that affect cognition, behavior, and executive function.
Self-assessing for Fetal Alcohol Syndrome is complex, as symptoms often overlap with ADHD, autism, or learning disabilities. Look for persistent patterns, rather than isolated events, such as:
If you suspect you have Fetal Alcohol Syndrome, consult a clinical geneticist or a developmental pediatrician who specializes in neurodevelopmental disorders. When you speak to your doctor, be direct: "I am concerned about symptoms that align with Fetal Alcohol Syndrome and would like a formal neurodevelopmental evaluation to better understand my cognitive and physical profile." If your concerns are dismissed, request a referral to a specialist center or a university-affiliated genetics clinic that has experience with prenatal exposure disorders.
