Any loss of skills warrants prompt paediatric and neurology review, not watchful waiting.","answer_md":"*When a little girl who was meeting her milestones begins to change — quieter hands, fewer words — it is frightening. Knowing the early pattern of Rett Syndrome turns that worry into the right next step.*\n\n## In short\nRett Syndrome is a rare neurodevelopmental condition, almost always in girls, with a characteristic pattern: a period of seemingly normal early development followed by a slowing or **loss of skills**, especially purposeful hand use and spoken words. The signature sign is **repetitive hand movements** — wringing, washing, mouthing or clapping motions that replace purposeful grasping. If your 3-year-old has lost skills she once had, this deserves a prompt developmental and paediatric-neurology review — not a wait-and-watch.\n\n## Early signs to notice around age 3\n**Loss of skills (regression)**\n- Losing purposeful hand use — no longer reaching, holding a spoon or picking up toys she once managed\n- Losing words or babble she previously had\n- Reduced social engagement or eye contact during a regression phase (often partly recovers later)\n\n**The hallmark hand movements**\n- Repetitive, almost continuous hand wringing, hand-washing motions, clapping, tapping or bringing hands to the mouth\n- These typically appear as purposeful hand use fades\n\n**Movement and growth**\n- Unsteady, wide or stiff walking, or loss of walking ability\n- Slowing of head growth compared with earlier (deceleration)\n- Breathing irregularities while awake — breath-holding or rapid breathing\n- Teeth-grinding, episodes of staring; sleep disturbance\n\n## When to seek help — promptly\nAny **loss of previously acquired skills**, at any age, is a signal to act rather than wait. Because Rett Syndrome can involve seizures and is confirmed through clinical evaluation and genetic testing (commonly the MECP2 gene), the right first stop is your paediatrician and a referral to paediatric neurology. Developmental therapy then supports communication, movement and daily participation alongside medical care.\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 the care of qualified clinicians — never from an online list.
