What is FASD?

Common description:

“FASD results when prenatal alcohol exposure affects the developing brain and body. FASD is a spectrum. Each person with FASD is affected differently. While more than 400 conditions can co-occur, FASD is at its core a lifelong neurodevelopmental condition. All people with FASD have many strengths. Early diagnosis and appropriate support are essential, especially for executive functioning.”

Foetal Alcohol Spectrum Disorder is a neurodevelopmental condition with lifelong cognitive, emotional and behavioural challenges. In addition to effects on the brain, FASD is a full-body diagnosis that can include more than 400 known conditions.

It’s more common than you think!


As many as 4%

of the UK population




The UK’s first small-scale active-case ascertainment study showed that 2-4% of people have FASD. That matches international studies and shows that FASD affects more people than autism. However FASD is sadly most often undiagnosed or misdiagnosed. FASD is often called a ‘hidden disability.’

This study is pending peer review. This figure is considered a conservative estimate due to limitations of the study.
