Fetal Alcohol Spectrum Disorder (FASD) is a lifelong condition caused by alcohol exposure during pregnancy, affecting growth, facial features, the brain, learning, attention and behaviour. Sensory Processing Differences describe how a child's brain takes in and responds to everyday sensations like sound, touch and movement, making them seem over- or under-sensitive. FASD has a known cause and affects many areas; sensory differences describe one pattern of experiencing the world and can occur alone or alongside many conditions, including FASD.

*Both can make a young child seem overwhelmed, fidgety or hard to settle — but one begins before birth, and the other is about how the brain handles everyday sensations.*

## In short
**Fetal Alcohol Spectrum Disorder (FASD)** is a lifelong condition caused by a baby being exposed to alcohol during pregnancy — it can affect growth, facial features, the brain, learning, attention and behaviour. **Sensory Processing Differences** describe how a child's brain takes in and responds to everyday sensations — sounds, textures, movement, light, touch — which can make them seem over- or under-sensitive. The big difference: FASD has a known cause (prenatal alcohol) and affects many areas of development, while sensory processing differences describe *one pattern of how a child experiences the world* — and can occur on their own or alongside many other conditions, including FASD.

## How they differ in everyday life
With **FASD**, the picture is usually broad. A child may have differences in growth, distinctive facial features, and challenges across learning, memory, attention, impulse control, language and daily skills. Because alcohol can affect the developing brain in many ways, no two children look exactly alike, and the diagnosis considers the whole story — including the pregnancy history — alongside careful developmental assessment.

With **sensory processing differences**, the focus is narrower and very specific: how your child reacts to *sensation*. One child may cover their ears at loud sounds, hate certain clothing textures or food, or melt down in busy places (over-responsive). Another may crave spinning, crashing and deep pressure, or barely notice pain (under-responsive). These patterns affect daily routines — dressing, eating, play, sleep — but are about sensory experience rather than a single underlying cause.

Importantly, a child with FASD often *also* has sensory processing differences. So this is not always 'either/or' — sometimes understanding the sensory piece is part of supporting a child who has FASD.

## When to seek a developmental check
If your child finds everyday sensations overwhelming, struggles to settle, or you have any concern about how they are learning, moving or behaving — and especially if there was alcohol exposure during pregnancy — it is worth a gentle, professional look. Early support helps either way, and a clinician can tell apart what is happening and why.

## The Pinnacle way
This is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our team looks at your child's whole picture — development, behaviour and how they process sensation — and shapes support around their strengths, drawing on [occupational therapy](/occupational-therapy) for sensory needs.

## Trusted sources
The CDC on Fetal Alcohol Spectrum Disorders and the effects of alcohol during pregnancy; the American Academy of Pediatrics and HealthyChildren on sensory and developmental concerns; the American Occupational Therapy guidance via ASHA-aligned resources on how children process sensation.
