Summary
- Fetal Alcohol Spectrum Disorder (FASD) is a lifelong neurodevelopmental condition caused by prenatal alcohol exposure (PAE).
- FASD affects brain development, learning, behaviour, and overall health, with symptoms ranging from memory and attention difficulties to social and emotional challenges.
- It is often called a “hidden disability” because most individuals do not have distinct facial features, making diagnosis difficult.
- FASD is frequently misdiagnosed or overlooked, with symptoms sometimes attributed to ADHD, autism, or behavioural issues.
- Early diagnosis and FASD-informed support can improve outcomes and help individuals reach their full potential.
Fetal Alcohol Spectrum Disorder (FASD) is a lifelong neurodevelopmental condition caused by prenatal alcohol exposure (PAE). Previously known as Fetal Alcohol Syndrome (FAS), FASD affects brain development, behaviour, learning, and overall health. There is no safe amount, type, or timing of alcohol during pregnancy—exposure at any stage can cause harm, even before a pregnancy is confirmed.
Internationally Standardised Definition of FASD
Fetal Alcohol Spectrum Disorder (FASD) is a diagnostic term used to describe impacts on the brain and body of individuals prenatally exposed to alcohol. FASD is a lifelong disability. Individuals with FASD will experience some degree of challenges in their daily living, and need support with motor skills, physical health, learning, memory, attention, communication, emotional regulation, and social skills to reach their full potential. Each individual with FASD is unique and has areas of both strengths and challenges.
The standardised definition of FASD was developed by CanFASD in an international consultative process. Read the Policy Action Paper outlining the development process.
What Determines the Severity of FASD Symptoms?
The level of harm is dependent on a wide range of factors, making it impossible to predict the outcome of alcohol exposure to any individual pregnancy.
Factors influencing the severity of FASD symptoms include:
- The amount and frequency of alcohol use during pregnancy
- Maternal health, including nutrition, tobacco use, and mental health
- Environmental influences such as stress and support systems
The Effects of FASD
The effects of FASD can vary significantly, often leading to its description as a “hidden disability”. Many individuals remain undiagnosed, with symptoms misattributed to other conditions like ADHD, autism, or behavioural disorders. Some children are mistakenly labelled as having “poor” behaviour or parenting issues when, in fact, their challenges stem from prenatal alcohol exposure (PAE).
FASD Characteristics
Distinctive characteristics—whether physical, developmental, or neurobehavioral—within the FASD spectrum are rarely noticeable at birth. Most individuals with Fetal Alcohol Spectrum Disorder (FASD) do not display distinct facial features, making early diagnosis challenging. FASD is often not recognised until school age, when difficulties with learning, attention, memory, and social interactions become more noticeable.
Children and adults with FASD commonly experience cognitive, behavioural, health, and learning challenges, including:
- Memory and attention difficulties
- Impaired cause-and-effect reasoning
- Impulsivity and difficulty with emotional regulation
- Challenges with receptive language and adaptive functioning
These difficulties are lifelong and have a significant impact on behaviour and relationships. Positive outcomes can be achieved when parents, caregivers, educators, and service providers are appropriately supported to understand that challenging behaviours in FASD are symptoms of brain-based disabilities, not deliberate defiance.

Why Language Matters
The language we use when talking about FASD is important. The Australian FASD Language Guide provides recommendations for using respectful language in discussions, reports, and presentations about FASD. The way we talk about FASD influences public perception, reduces stigma, and fosters a more supportive environment for individuals with fetal alcohol spectrum disorder and their families.
Why Service Providers Must Be FASD-Informed
It is critical for service providers—including healthcare professionals, educators, and social workers—to be FASD-informed. Simply knowing about Fetal Alcohol Spectrum Disorder (FASD) is not enough; effective support requires an individualised, evidence-based approach. Without FASD training, misinterpretation of behaviours can lead to misdiagnosis and inappropriate interventions. Learn more about FASD-informed practice and professional training here
