Early signs of Rett Syndrome on a home visit

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• Reduced eye contact, less social smiling, becoming more withdrawn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.
