# Prematurity-Related Developmental Risk vs Rett Syndrome in Young Children Canonical: https://pinnacleblooms.org/ask/what-is-the-difference-between-prematurity-related-developmental-risk-and-rett-syndrome-in-young-children Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited Prematurity-Related Developmental Risk means a baby born early may need extra time and monitoring to reach milestones, measured by corrected age, and many catch up well — it is a risk to watch, not a diagnosis. Rett syndrome is a rare genetic condition, almost always in girls, where a child develops typically at first then loses skills already gained, such as purposeful hand use, often with repetitive hand movements. The core difference: prematurity is about needing more time after an early start, while Rett involves losing previously present skills, which always needs prompt review. *Two very different journeys can both worry a parent — one begins with an early arrival, the other with a quiet change in a thriving little girl — and knowing them apart brings calm and clarity.* ## In short **Prematurity-Related Developmental Risk** means a baby born early (before 37 weeks) may need a little extra time and watchful support to reach milestones, because their brain and body had less time to grow in the womb — it is a *risk to monitor*, not a fixed diagnosis, and many premature children catch up beautifully. **Rett syndrome** is a rare genetic condition, almost always in girls, caused by a change in the *MECP2* gene; here a child usually develops typically for the first 6–18 months, then shows a slowing or loss of skills already gained, such as purposeful hand use and babble. The simplest difference: prematurity is about *needing more time after an early start*, while Rett involves a *distinctive pattern of losing skills* that were already present. ## How they differ **Prematurity-Related Developmental Risk** is best understood through *corrected age* — we count milestones from your baby's due date, not their birth date. A baby born two months early may sit, babble or walk a couple of months "late" by calendar age, yet be right on track for their corrected age. Risk rises with how early or how small a baby was, but the path is usually one of steady catching-up, especially with early nurturing support and follow-up. **Rett syndrome** follows a recognisable course. After an apparently typical start, a child enters a phase of *regression* — losing purposeful hand skills and often gaining repetitive hand movements (such as wringing or mouthing), slowing head growth, and changes in walking, communication and breathing patterns. It is a genetic, lifelong condition, and it is not caused by being born early. The key contrast for a parent: a premature child is generally *moving forward, just on their own timeline*; in Rett syndrome there is a *clear loss of skills the child once had*. Any loss or regression of previously gained skills — at any age, premature or not — always deserves a prompt developmental and medical review. ## When to seek a review For a premature baby, attend all scheduled follow-up checks and raise concerns if milestones (adjusted for corrected age) seem persistently delayed. For *any* child, seek review promptly if you notice loss of skills already gained — hand use, babble, eye contact, walking — or unusual repetitive hand movements or slowing head growth. Regression is the signal that matters most. ## The Pinnacle way This is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our team supports premature children with developmental follow-up and gentle, milestone-led [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate), and works alongside families navigating rarer genetic conditions.
