Dyslexia vs Fetal Alcohol Spectrum Disorder in Young Children

Two children may both struggle with reading — but the story behind those struggles, and the support they need, can be very different.

In short

Dyslexia is a specific learning difference that mainly affects reading, spelling and the sound–letter side of language, in a child whose overall thinking and early development are otherwise on track. Fetal Alcohol Spectrum Disorder (FASD) is a wider, lifelong condition caused by alcohol exposure before birth — it can affect growth, facial features, attention, memory, learning, movement and behaviour across many areas, not just reading. In short: dyslexia is a focused reading-and-language difference; FASD is a broad, whole-child developmental condition with a known prenatal cause.

How they differ in young children

With dyslexia, you typically see a bright, curious child who follows conversations and ideas well, yet finds learning letters, rhyming, sounding out words and spelling unexpectedly hard — often harder than their other skills would suggest. It tends to become clearer around the early school years (roughly age 6–8), when formal reading begins. There is usually no other unexplained delay across development.

With FASD, the picture is broader and often visible earlier. Because alcohol can affect the developing brain and body before birth, children may show slower growth, certain facial features, difficulties with attention, memory and impulse control, challenges with movement and coordination, and learning differences across several areas. Reading may be one of many things that is harder. FASD has a clear cause — prenatal alcohol exposure — while dyslexia does not.

In practice, the two can look similar on the surface (a child who finds reading tough), so what matters is looking at the whole child: is the difficulty mainly in reading and language, or spread across growth, attention, memory, movement and behaviour together?

When to seek a review

Seek a developmental review if reading and spelling are persistently harder than expected for your child's age and overall ability, or if you notice difficulties across several areas at once — attention, memory, coordination, growth or behaviour. An early, thoughtful assessment helps tell apart a focused reading difference from a broader developmental picture, so support is matched to your child — never guessed.
