Fetal Alcohol Syndrome
Fetal alcohol syndrome is the severe phenotypic end of prenatal alcohol exposure, recognized by characteristic facial dysmorphology, growth impairment, and central nervous system dysfunction. Identification should trigger multidisciplinary neurodevelopmental assessment and needs-based intervention rather than reliance on facial findings alone.
Clinical recognition
When to suspect fetal alcohol syndrome
Use phenotype and functional impairment to trigger evaluation; do not wait for a complete exposure history.
Fetal alcohol syndrome is the severe form of fetal alcohol spectrum disorder associated with prenatal alcohol exposure. The defining clinical pattern includes growth retardation, characteristic facial abnormalities, and neurobehavioral abnormalities; diagnostic frameworks also incorporate structural or functional CNS impairment. cell+4cellDoes moderate drinking harm the fetal brain?

At the initial developmental or behavioral visit, obtain a nonjudgmental prenatal exposure history and document current functional concerns across school, home, peer, and self-care settings. Prenatal alcohol exposure is associated with broad neurodevelopmental and behavioral needs, and unrecognized needs can delay interventions that may improve outcomes.

Refer a child or adolescent with probable prenatal alcohol exposure and significant physical, developmental, or behavioral difficulties for a FASD-focused assessment. Referral should be sensitive and stigma-aware, and pathways should connect primary care, developmental services, community pediatrics, and child mental-health services. nice org uknice org ukQuality statement 3: Referral for assessment | Fetal alcohol spectrum disorder | Quality standards | NICE

Diagnostic pathway
Structure the assessment around phenotype and function
A diagnosis should support a management plan, not merely assign a label.
Document growth trajectory, head growth when available, dysmorphic examination findings, neurologic history, and functional impairment. Published diagnostic approaches use growth, facial phenotype, CNS anomalies or neurodevelopmental dysfunction, and prenatal alcohol exposure as core diagnostic pillars, although terminology and operational criteria differ across systems.

The three midline facial characteristics described as discriminant for fetal alcohol syndrome include short palpebral fissures, a smooth philtrum, and a thin upper vermilion border. Facial assessment should be performed using a standardized method when possible because computer-based facial analysis and structured diagnostic coding have been evaluated to recognize FAS facial characteristics. publications aap+1publications aapFacial Dysmorphism Across the Fetal Alcohol Spectrumpublications aapFetal Alcohol Spectrum Disorder
Assess neurodevelopmental function beyond global cognition. The documented burden of FASD includes intellectual disability, ADHD, developmental coordination disorder, language disorder, anxiety, mood disorder, autism spectrum disorder, trauma-related disorders, disruptive behavior disorders, substance use disorder, and suicidality; screening should be driven by the patient's presentation and immediate safety needs. BMJBMJCharacterising fetal alcohol spectrum disorder in Canada
Obtain developmental and educational records, including individualized education program evaluations, psychoeducational testing, language testing, disciplinary history, and adaptive-function concerns; school and independent-living difficulties are common areas of impairment.

Diagnostic framework and differential diagnosis
Use the local diagnostic framework consistently and state the framework in the consultation note. Commonly used systems include the Collaboration on FASD Prevalence clinical diagnostic guidelines, the University of Washington 4-Digit Diagnostic Code, and Canadian guidelines; German criteria likewise organize diagnosis around growth, facial findings, CNS abnormalities, and prenatal alcohol exposure.

Do not attribute all developmental or behavioral impairment to prenatal alcohol exposure. A dysmorphology, genetics, neurology, developmental-behavioral pediatrics, or psychology consultation is appropriate when the phenotype is atypical, congenital anomalies suggest an alternative syndrome, developmental regression is present, focal neurologic findings occur, or formal neuropsychological characterization is needed to direct services. Multidisciplinary assessment is a central feature of FASD diagnostic practice.

Needs-based care
Treat functional impairment and reduce environmental mismatch
There is no single corrective treatment; management is individualized by the assessed impairment profile.
Translate the assessment into a written, prioritized care plan that names the responsible service, target impairment, and reassessment interval. Reported intervention recommendations for FASD include FASD-specific education or intervention, counseling, allied-health services, behavioral therapy, medication or medical referral, environmental adaptation, anticipatory guidance, and reassessment. BMJBMJCharacterising fetal alcohol spectrum disorder in Canada
For school-age patients, provide diagnostic documentation that describes functional effects rather than relying on the diagnosis alone. Recommended accommodations may include predictable routines, adjusted expectations, teacher assistance, and adaptations to the environment and supports; school difficulty, suspension or expulsion, and need for teacher assistance are reported functional concerns. BMJBMJCharacterising fetal alcohol spectrum disorder in Canada
Address caregiver capacity as a clinical variable. Families may need counseling, support groups, respite or daycare, help obtaining basic needs, safety planning, legal services, and future substitute-decision-making or guardianship planning. These supports should be coordinated alongside developmental therapies rather than deferred until a crisis. BMJBMJCharacterising fetal alcohol spectrum disorder in Canada

Medication decisions
No medication regimen should be selected solely for fetal alcohol syndrome. When ADHD, anxiety, mood disorder, psychosis, insomnia, aggression, substance use disorder, or another comorbid condition is diagnosed, prescribe and monitor treatment according to that condition's standard assessment and safety framework, while pairing medication with environmental and behavioral supports. Medication or psychopharmacology is one component of the broader intervention profile reported in FASD care. BMJBMJCharacterising fetal alcohol spectrum disorder in Canada
Before escalating psychotropic therapy for aggression, impulsivity, or inattention, reassess language demands, sleep, trauma exposure, school mismatch, caregiver stress, and unrecognized learning disability. Behavioral problems in FASD commonly coexist with language, developmental coordination, mood, anxiety, trauma-related, and disruptive behavior disorders, which can alter the intervention target. BMJBMJCharacterising fetal alcohol spectrum disorder in Canada
Longitudinal care
Follow function over time and address prevention
Reassess at developmental transitions because needs change even when the diagnosis does not.
Schedule reassessment when a child enters school, changes educational placement, develops new behavioral symptoms, approaches adolescence, or transitions to adult services. FASD-associated difficulties include school failure, employment problems, impaired independent living, housing instability, legal needs, and need for guardianship or substitute decision-making; anticipatory planning should begin before these transitions become urgent. BMJBMJCharacterising fetal alcohol spectrum disorder in Canada
At follow-up, review whether recommended services are actually available and being used. Database-based FASD care models specifically track intervention recommendations and local service availability, reflecting the practical gap between identifying a need and obtaining treatment.

For patients who may become pregnant, provide clear prevention counseling that alcohol exposure during pregnancy is the causal exposure underlying fetal alcohol spectrum disorders. Couple this with screening and treatment referral for alcohol-related problems when indicated, using a nonstigmatizing approach that preserves engagement in prenatal and primary care.
