Diagnosis, where needed, requires an appropriately qualified healthcare professional.","answer_md":"*A diagnosis like Rett syndrome can make the future feel uncertain — but with the right care, many children grow into adulthood, and every day of support builds quality of life.*\n\n## In short\nMost children with Rett syndrome **live well into adulthood** — many into their 40s, 50s and beyond — with research suggesting the majority survive past mid-life. Rett syndrome is a lifelong neurodevelopmental condition, not a rapidly shortening one, and life expectancy varies widely from child to child depending on their overall health, heart rhythm, breathing, nutrition and the day-to-day care they receive. With attentive medical and therapy support, the focus rightly shifts from *how long* to *how well* — comfort, communication, mobility and joy.\n\n## What shapes the picture\nRett syndrome affects girls far more often than boys, and each child's journey is unique. A few health areas, when watched and managed well, make a real difference to both wellbeing and longevity:\n\n- **Heart rhythm** — some children have changes in heart rhythm (a prolonged QT interval), so regular cardiac monitoring is important.\n- **Breathing patterns** — irregular breathing and breath-holding are common and benefit from review by the medical team.\n- **Nutrition and swallowing** — safe, well-supported feeding protects growth, energy and chest health.\n- **Bones and movement** — physiotherapy and managing scoliosis and seizures (where present) support comfort and mobility.\n- **Everyday care and connection** — responsive communication, gentle therapy and a loving routine protect a child's quality of life every single day.\n\nThe encouraging truth is that proactive, coordinated care — paediatrician, cardiologist, therapists and family together — directly supports both how comfortably and how long a child lives.\n\n## When to seek support\nStay in close contact with your child's medical team for regular heart and breathing checks, seizure review, feeding and growth monitoring, and bone and posture care. Seek prompt medical attention for any new breathing difficulty, fainting, suspected seizures, choking during feeds, or sudden changes in alertness. Therapy works alongside — never instead of — this medical care.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or online form. From there, your child receives a tailored developmental and functional profile and a plan that grows with them, drawing on our [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) and [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) support to nurture movement, communication and daily comfort. Learn how your child's strengths are mapped through the [clinician-administered AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated), and explore more developmental guidance on our [home page](/).\n\n## Trusted sources\nWHO ICD-11 listing for Rett syndrome; guidance from the American Academy of Pediatrics (HealthyChildren.org) on caring for children with complex neurodevelopmental conditions; ASHA resources on communication support. Figures on survival reflect published clinical understanding that most individuals live into adulthood, with wide individual variation.\n\n**Next step —** Want a clear, caring plan built around your child's strengths and comfort? [Book an assessment with a Pinnacle clinician](/ask/what-is-the-abilityscore-and-how-is-it-calculated).\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare
