Screening and diagnostic pathway for FASD under 7
FASD in children under 7 follows a staged pathway: non-judgemental prenatal alcohol risk screening, then multidisciplinary diagnostic assessment of the three sentinel facial features, pre/postnatal growth, CNS involvement across functional domains, and documented or probable exposure. There is no single test — diagnosis is a clinical synthesis, and developmental surveillance continues regardless of facial findings.
The child in front of you may carry a prenatal exposure no one has named yet — a structured pathway is what brings it to light.
In short
For children under 7, FASD (ICD-11 LD2F.00) is identified through a staged pathway: risk screening (prenatal alcohol history, growth, antenatal records), followed by multidisciplinary diagnostic assessment examining the three sentinel facial features, growth, structural/functional CNS involvement and documented or probable prenatal alcohol exposure. There is no single test — diagnosis is a clinical synthesis against recognised criteria, and developmental surveillance should continue regardless of facial findings.
The pathway, briefly
1. Screen. Take a non-judgemental maternal alcohol history; flag growth restriction, microcephaly, and any developmental concern. A positive screen routes to formal assessment — do not wait for facial dysmorphology, which is absent in most of the spectrum.
2. Confirm exposure and dysmorphology. Assess the three sentinel features (short palpebral fissures, smooth philtrum, thin upper lip) using a validated lip–philtrum guide, plus pre/postnatal growth and head circumference.
3. Evaluate CNS across domains. A multidisciplinary team profiles cognition, language, motor, attention/executive function, memory, adaptive behaviour and sensory regulation. Under 7, several domains are still emerging — document baseline now and re-evaluate, as some functional deficits clarify with age.
4. Differential and comorbidity. Exclude or note co-occurring genetic, sensory and attachment factors. Refer promptly to genetics or paediatric neurology where indicated.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online form. Our clinician-administered structured assessment maps the functional domains above so co-management is precise. Explore Fetal Alcohol Spectrum Disorder, our developmental assessment pathway and how the AbilityScore® is calculated.
Trusted sources

Next step — Refer a child with suspected prenatal alcohol exposure for a structured multidisciplinary assessment at a Pinnacle Blooms Network centre.
This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
What to notice
Pre/postnatal growth restriction, microcephaly, the three sentinel facial features, and emerging deficits in language, attention, executive function and adaptive behaviour — alongside a documented or probable prenatal alcohol history.
In everyday life
Take the maternal alcohol history without judgement and early — most children on the spectrum have no facial dysmorphology, so exposure history is often the decisive clue.
Questions families ask
Can FASD be diagnosed without the facial features?
Yes. The three sentinel facial features are present in only a minority of the spectrum. Diagnosis can rest on documented or probable prenatal alcohol exposure together with significant CNS involvement across functional domains, assessed by a multidisciplinary team.
Is there a single test for FASD?
No. FASD is a clinical synthesis against recognised criteria — combining alcohol-exposure history, growth, dysmorphology and a multidisciplinary functional profile. No blood test or scan confirms it alone.
Why re-evaluate young children over time?
Under 7, cognition, language and executive function are still emerging. Some functional deficits clarify only with age, so a baseline now plus structured re-evaluation gives the most accurate picture.
