A worker sees someone repeat the same mistake for the fifth time this week, after being told clearly, more than once, exactly what to do differently. It's easy to read that as defiance or a lack of effort. For someone with FASD, it's often neither. It's a genuine, brain-based difficulty translating an instruction into consistent action, and reading it as a choice rather than a disability is one of the most common and damaging mistakes support work makes around this condition.
What is FASD?
Fetal Alcohol Spectrum Disorder is a brain-based, lifelong neurodevelopmental condition caused by alcohol exposure before birth. It's a permanent disability, not something a person grows out of or a temporary developmental delay, and it needs ongoing, informed support across a person's whole life. Research has linked FASD with more significant executive function difficulties than even ADHD, affecting the mental processes that let someone plan, organise, stay focused and connect ideas together.
Why is FASD so often missed or misread?
Unlike some conditions, FASD doesn't always come with visible physical features, so there's often nothing obvious flagging that a person's brain works differently in this specific way. What shows up instead is behaviour: difficulty following multi-step instructions, impulsivity, trouble learning from consequences the way expected, and a pattern of social vulnerability, being easily led, struggling to read risky situations. Without the FASD lens, all of that reads as a discipline problem, an attitude problem, or gets folded into a different diagnosis like ADHD, rather than understood as a distinct brain-based condition needing its own approach.
What is the can't/won't trap, and why does it matter so much?
It's the assumption that someone is choosing not to comply, when the more accurate read is often that they genuinely can't, not in a general sense, but in this specific moment, with this specific instruction, given how their executive function works. Reading a can't as a won't leads directly to responses, punishment, escalating consequences, frustration, that treat a disability as a behavioural choice. That mismatch is a large part of why people with FASD have historically been so poorly served by systems built around traditional behaviour management.
What actually helps?
- Concrete, specific, one-step-at-a-time instructions rather than multi-step verbal directions
- Consistent routines and environments, since predictability reduces the executive function load required in the moment
- Reducing reliance on the person's ability to reason through consequences in real time, and building in external structure instead
- Recognising social vulnerability, someone easily led into risky situations by peers, as a genuine support need rather than a character flaw
The reframe that changes everything
Before responding to a repeated mistake, ask whether this looks more like won't or can't. If there's real doubt, treat it as can't. The cost of extra structure and patience is far lower than the cost of punishing a disability as if it were defiance.
How CORA's course fits into this
CORA's course Foetal Alcohol Spectrum Disorder (FASD): Understanding & Support, part of the Disability Understanding & Daily Life stream in the course library, covers FASD as a brain-based disability often missed in diagnosis and misread on shift, recognising the executive function and social-vulnerability pattern, supporting with structure and concreteness, and avoiding the can't/won't trap that has historically shaped how people with FASD are treated. It builds a worker's understanding and judgement, and does not replace an individual's specific support plan or clinical guidance.

What is FASD?
Fetal Alcohol Spectrum Disorder, FASD, is a brain-based, lifelong neurodevelopmental condition caused by alcohol exposure before birth. It's a permanent disability, not something a person grows out of, and it affects executive function, memory, attention and behaviour to varying degrees.
Why is FASD often missed or misdiagnosed?
FASD doesn't always have visible physical features, and its effects on behaviour, impulsivity, difficulty following instructions, social vulnerability, are easily mistaken for a discipline issue, ADHD, or a conduct problem rather than a brain-based disability requiring a different kind of support.
What is the can't/won't trap?
It's the assumption that a person with FASD is choosing not to comply, when they are often genuinely unable to, due to executive function differences affecting planning, impulse control and understanding consequences. Reading a can't as a won't leads to responses that punish a disability rather than support it.
What support strategies actually help someone with FASD?
Structure, concrete and specific instructions, consistent routines, and reduced reliance on verbal reasoning alone tend to help. Traditional behaviour management approaches that assume the person can reflect and self-correct in the moment often don't work as intended for FASD.
