Is Rett Syndrome considered a disability?

When a parent first hears the words "Rett Syndrome", the next question is often the most human one — does this mean my daughter has a disability, and what does that really mean for her?

In short

Yes — Rett Syndrome is recognised as a disability, because it affects how a child moves, communicates and manages everyday activities, usually emerging after a period of seemingly typical early development. But "disability" here is a description of the support your child needs to thrive, not a ceiling on who she can become. Girls with Rett Syndrome understand far more than they can show, and with the right communication and movement support they connect, learn and flourish in their own way.

What "disability" really means here

Rett Syndrome is a genetic neurodevelopmental condition, most often linked to changes in the MECP2 gene, and it predominantly affects girls. Internationally it is understood through the WHO's model of functioning — meaning disability is the gap between what a child can do and the support around her, not a fixed label of "less". In practice, families notice:

• A slowing or loss of purposeful hand use, often with repetitive hand movements
• Changes in walking, balance and coordination
• Differences in spoken communication — which is why eye-gaze and assistive communication matter so much
• A clear, watchful, present child behind it all

Because those hands and words become harder to use, the right framing is ability-first: we build the routes — communication devices, physiotherapy, daily-living support — through which her capability already wants to flow.

When to seek support

If you notice a loss of previously acquired skills — hand use, babble, walking or social engagement — at any age, that always warrants a prompt developmental and medical review. Earlier support means earlier ways to connect, and that changes everything for a child's confidence and a family's calm.
