Any loss of skills warrants prompt developmental and genetic evaluation — only a clinician can confirm.","answer_md":"*When a little girl who was growing beautifully begins to change in ways that worry you, naming what you're seeing is the first step towards getting her the right support.*\n\n## In short\nRett Syndrome is a rare genetic neurodevelopmental condition (ICD-11 LD90.0) seen almost entirely in girls. By age 4, many families have already noticed a distinctive pattern: a slowing or loss of skills after an early period of typical development, loss of purposeful hand use replaced by repetitive hand movements, and changes in walking and communication. If you recognise these, a developmental check and genetic evaluation are the right next steps — only a clinician can confirm.\n\n## Signs to watch in a 4-year-old\n**Hand use and movements (often the most telling sign)**\n- Loss of purposeful hand skills she once had — holding toys, pointing, feeding herself\n- Repetitive hand movements: wringing, washing-like motions, mouthing, clapping or tapping, often almost continuous when awake\n\n**Communication and social engagement**\n- Loss or slowing of spoken words and babble after an earlier period of cooing or first words\n- Reduced eye contact for a time, sometimes followed by intense, expressive \"eye gaze\" communication\n- Withdrawal from social back-and-forth she previously enjoyed\n\n**Movement and growth**\n- Changes in walking — unsteady, wide-based or stiff gait, or trouble starting to walk\n- Slowing of head growth compared with her early months\n- Stiffness, toe-walking, or difficulty with coordinated whole-body movement\n\n**Other patterns families notice**\n- Irregular breathing while awake — breath-holding, fast breathing or air-swallowing\n- Disturbed sleep, episodes of distress or laughter, teeth grinding\n\n## When to act\nRett Syndrome typically follows a recognised pattern: a period of apparently typical early development, then a phase of regression — most often between 1 and 4 years — where skills plateau or are lost. Any loss of previously acquired skills, at any age, deserves prompt clinical attention rather than waiting. Because Rett is most often caused by a change in the *MECP2* gene, confirmation involves genetic testing alongside developmental assessment. Ask your paediatrician for a referral; early support for communication, hand function, movement and feeding makes a real difference to her quality of life.\n\n## The Pinnacle way\nA 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 — this page helps you recognise a pattern, not label your daughter. Our teams support girls with Rett-related needs through [speech and communication therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) (including eye-gaze and alternative communication), [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) for hand use and daily skills, and movement support — built on 25 million+ therapy sessions and 700+ therapists across 70+ centres. You can begin with a [developmental screening](/) at any centre.\n\n## Trusted sources\nAligned with the WHO ICD-11 framework (LD90.0), and developmental guidance from the American Academy of Pediatrics and CDC \"Learn the Signs. Act Early.\", with genetic and clinical evaluation through paediatric neurology services such as those at NIMHANS.\n\n**Next step —** if you've noticed loss of hand skills or words in your daughter, book a developmental screening or speak with the Pinnacle clinical team on WhatsApp: +91 91001 81181.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an
