FASD is an umbrella term, not a single condition. It includes recognised patterns: Fetal Alcohol Syndrome (FAS), partial FAS (pFAS), Alcohol-Related Neurodevelopmental Disorder (ARND), and Alcohol-Related Birth Defects (ARBD). These describe different combinations of effects on growth, facial features, brain and learning — not a simple mild-to-severe scale. A clinical assessment and diagnosis happen only at a Pinnacle centre.

*When you hear "spectrum," it can sound vast and frightening — but FASD simply means alcohol can affect a developing baby in different ways, and each pattern has a name so the right support can follow.*

## In short
Fetal Alcohol Spectrum Disorder (FASD) is an umbrella term, not a single condition. It describes a range of effects that can occur when a baby is exposed to alcohol before birth. Within it sit a few recognised patterns — most commonly **Fetal Alcohol Syndrome (FAS)**, **partial FAS (pFAS)**, **Alcohol-Related Neurodevelopmental Disorder (ARND)**, and **Alcohol-Related Birth Defects (ARBD)**. These are not "mild to severe" levels in a tidy line; they are different combinations of how a child's growth, facial features, brain and learning may be affected.

## The recognised patterns
- **Fetal Alcohol Syndrome (FAS)** — the most fully recognised pattern, involving distinctive facial features, slower growth, and differences in how the brain develops and a child learns.
- **Partial FAS (pFAS)** — some, but not all, of the FAS features are present, usually with the brain and learning differences.
- **Alcohol-Related Neurodevelopmental Disorder (ARND)** — differences in attention, memory, learning, behaviour and self-control, without the full set of physical features.
- **Alcohol-Related Birth Defects (ARBD)** — effects on body systems such as the heart, kidneys, hearing or skeleton.

Every child is wonderfully individual: two children under the same term may have very different strengths and support needs. What matters most is not which label fits, but understanding your child's profile so support is precise and kind.

## When to seek a developmental check
If there was alcohol exposure in pregnancy, or you notice differences in your child's growth, learning, attention or behaviour, a developmental check is a calm, sensible next step. Early support genuinely shapes outcomes — communication, learning and everyday independence all respond well when help starts early.

## The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an online description or app. Begin by [understanding FASD](/fasd) and [how your child's starting point is measured](/ask/what-is-the-abilityscore-and-how-is-it-calculated), then explore [occupational therapy](/occupational-therapy) and [speech therapy](/speech-therapy) where they help most.

## Trusted sources
CDC guidance on Fetal Alcohol Spectrum Disorders; WHO ICD-11 framework for alcohol-related developmental conditions; American Academy of Pediatrics developmental guidance.

**Next step —** If alcohol exposure in pregnancy is a concern, [book a developmental check with a Pinnacle clinician](/fasd) for clear, reassuring answers.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
