Rett Syndrome

Early signs of Rett Syndrome on a home visit

Watch for regression in a baby girl who was developing normally — loss of purposeful hand use and babble after 6–18 months, repetitive hand-wringing or washing movements, slowing head growth, and breathing irregularities. Any loss of acquired skills needs prompt medical referral; only a clinician can confirm.

Early signs of Rett Syndrome on a home visit
Spotting Rett Syndrome early at home — Ask Pinnacle, the Child Development Kośa

During a home visit, the first person to notice that a baby's hands have changed how they work is often the frontline health worker — and that early eye matters enormously.

In short

Rett Syndrome (ICD-11 LD90.0) typically follows a striking pattern: a baby girl who seemed to be developing normally for the first 6–18 months, then slows down or loses skills she once had. The strongest early clue is regression — losing purposeful hand use and emerging words — together with repetitive hand movements like wringing, washing or mouthing. Any loss of previously gained skills warrants prompt medical referral, never "wait and watch".

Signs to look for during a home visit

Early concerns (6–18 months)
  • Head growth slowing — the head may seem to stop catching up with the body
  • Reduced eye contact, less social smiling, becoming more withdrawn
  • Floppy or low muscle tone; delayed sitting or crawling

The hallmark — regression

  • Loss of skills the child once had: babble or words fading, purposeful hand use disappearing
  • Hands no longer reach for or hold toys as before

Repetitive hand movements (very characteristic)

  • Hand-wringing, hand-washing motions, clapping, tapping or putting hands to mouth, often continuous when awake

Other signs

  • Breathing irregularities when awake (breath-holding, fast breathing)
  • Walking that is unsteady, on toes, or not emerging
  • Predominantly affects girls

When to refer

Any loss of acquired skills at any age is a medical red flag — refer the same week to a paediatrician for assessment. Note what the parent first noticed and roughly when. While referral is arranged, parallel occupational therapy and developmental support help protect skills and confidence.

What to watch

Escalate to same-week paediatric referral on any loss of previously gained skills — fading words, hands no longer reaching for toys — especially with repetitive hand-wringing or washing movements and slowing head growth in a girl who was developing normally.

Try this at home

On a home visit, ask the parent one direct question: 'Could she do anything before that she can't do now?' Loss of any skill is the single highest-yield clue for Rett Syndrome.

Frequently asked

At what age do Rett Syndrome signs usually appear?

Most babies with Rett Syndrome develop typically for the first 6–18 months, then show regression — losing hand use and emerging words. The repetitive hand movements often become noticeable during this period.

Does Rett Syndrome affect boys?

It predominantly affects girls. It is far rarer and usually more severe in boys. On a home visit the pattern of regression plus repetitive hand movements is the key clue regardless of sex.

What should I do if I notice these signs?

Do not wait and watch. Note what the parent first observed and when, then refer the same week to a paediatrician. Any loss of acquired skills is a medical red flag.
