Foetal Alcohol Spectrum Disorder (FASD) is a neurodevelopmental condition resulting from prenatal alcohol exposure. Even though it is one of the most common neurodevelopmental disorders internationally, FASD is significantly under reported across the UK. This under reporting means that there are implications for service planning, diagnosis and long-term outcomes for affected individuals and their families.
To understand the reason why FASD is under-reported it is necessary to look beyond prevalence estimates and consider how data is collected, how diagnoses are conducted and how stigma impacts practice.
What Does the Data Tell Us?
Data collected form hospitals in England suggests that there are very low rates of FASD diagnosis. However, these statistics contrast both international prevenance estimates and UK patterns of prenatal alcohol exposure (PAE). Since PAE is estimated to be common in the UK, this should be reflected in health records more than it is currently.
Research analysing Hospital Episode Statistics discovered no clear relationship between regions with higher levels of alcohol related admissions in women and reported FASD diagnoses in children. This suggests that there is an issue with under-reporting rather than an absence of FASD. It is important to note that hospital data only captures individuals who are admitted and correctly diagnosed, meaning many people with FASD are never counted.
Why is FASD So Often Missed?
A contributing factor is that FASD is a spectrum condition. Many individuals do not present with characteristic physical features, and difficulties may not become evident until later on in childhood, adolescence, or adulthood. Therefore, FASD is often a “hidden disability”.
FASD also frequently co-exists amongst other neurodevelopmental disorders such as autism, ADHD or difficulties associated with attachment and trauma. Without the appropriate training, professionals may focus on these other presentations, leaving the FASD unrecognised. This may result in fragmentation of support that does not meet the individual’s needs.
The stigma surrounding alcohol consumption during pregnancy complicates identification. Conversations regarding prenatal alcohol exposure are sensitive, and a fear of blame may limit accurate documentation.
Data Systems and Gaps in Diagnosis
Passive surveillance systems (i.e., counting the number of diagnosed cases) are highly dependent on clinicians recognising and recording FASD accurately. However, outpatient datasets rarely include reliable diagnostic coding, and there is no routine screening pathway for FASD in the UK. Due to the fact that diagnosis typically occurs years after birth, crucial information about PAE may be unavailable by the time concerns have arisen.
Limited diagnostic capacity also plays an important role. Specialist FASD services remain insufficient in England, meaning that even when FASD is suspected to be present, families may struggle to receive the support they need.
Why Under‑Reporting Matters
Without accurate prevalence data, services do not have the power to receive appropriate commission, professionals lack training, and individuals with FASD are at a higher risk of unmet needs and poor mental health.
Improving recognition requires increased professional training, improved recording of prenatal risk factors, consistent diagnostic frameworks, and the use of respectful and non-stigmatising language. FASD is not rare, however, until systems improve, it will continue to remain hidden and under-reported.
Improving the visibility of FASD is necessary to ensure that individuals and families receive timely, informed, and effective support.
