# When to refer suspected Rett syndrome for developmental therapy

Refer for developmental therapy at the point of clinical suspicion — in parallel with genetic and neurological workup, not after it. The regression phase (6–18 months) is when speech/AAC, OT and physiotherapy best preserve function. Co-refer seizures and airway concerns to paediatric neurology urgently.

*When you suspect Rett syndrome, the instinct to wait for genetic confirmation is understandable — but functional support should not wait for it.*

## In short
Refer for developmental therapy **at the point of clinical suspicion**, in parallel with — not after — genetic and neurological workup. The hallmark of [Rett syndrome](/rett) is a regression phase (typically 6–18 months) with loss of purposeful hand use, emerging hand stereotypies, slowing head growth and communication loss; this window is precisely when therapeutic input preserves function. Do not gate referral on confirmed *MECP2* status. Concurrently route any seizure activity, breathing dysregulation or feeding/airway concern to paediatric neurology and medical management.

## The clinical picture, and why timing matters
Rett syndrome (**ICD-11 LD90.4**) is an X-linked neurodevelopmental disorder, most commonly *MECP2*-related, following a recognised four-stage course: early stagnation, rapid regression, a plateau (pseudo-stationary) phase, and late motor deterioration. The functional priorities differ by stage, which is why early multidisciplinary referral is decisive:

- **Regression/plateau phase** — speech and language therapy for [communication](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate), including AAC and eye-gaze access, since receptive ability often outstrips expressive output; occupational therapy for hand function and stereotypy management; physiotherapy to preserve ambulation and protect against contracture.
- **Across all stages** — scoliosis surveillance, gait and tone management, feeding and oromotor support, and dysautonomia-aware planning.

The evidence base favours sustained, individualised therapy that maintains mobility and maximises a non-verbal child's agency over her environment. Delaying therapy until genetic confirmation forfeits irreplaceable neuroplastic opportunity during regression.

## When to refer — the decision
Refer **now** if you observe: deceleration of head growth, loss of acquired hand skills with emerging midline hand wringing or mouthing, regression of babble or social engagement, or gait apraxia. Co-refer to paediatric neurology for genetic testing and seizure assessment; epilepsy here is a medical-urgency pathway, not therapy-first. Developmental therapy proceeds alongside that workup.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — never from an online form or this page. Our clinicians administer a structured, [clinician-led assessment](/ask/what-is-the-abilityscore-and-how-is-it-calculated) that profiles each child against her own baseline across communication, motor and functional domains, then builds a stage-appropriate plan spanning [speech and AAC](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) and hand-function work. With 700+ therapists across 70+ centres in 4 states, co-management with your referring neurology team is straightforward.

## Trusted sources
WHO ICD-11 (LD90.4, Rett syndrome); American Academy of Pediatrics developmental surveillance guidance; ASHA on AAC for complex communication needs. Paraphrased for clinical use.

**Next step —** Refer at suspicion, in parallel with genetic workup. [Book a developmental assessment](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) so therapy can begin during the window that matters most.

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