# Developmental Coordination Disorder vs Rett Syndrome Canonical: https://pinnacleblooms.org/ask/what-is-the-difference-between-developmental-coordination-disorder-and-rett-syndrome-in-young-children Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited Developmental Coordination Disorder (DCD) is a stable difference in motor planning and coordination — a child is clumsier than expected at tasks like handwriting, buttons or sport despite normal intelligence, and improves steadily with occupational and physiotherapy. Rett syndrome is a rare genetic neurodevelopmental condition, almost always in girls, where a child develops typically for the first 6–18 months and then loses skills she had gained — especially purposeful hand use and sometimes speech — alongside repetitive hand movements and slowing head growth. The defining difference is regression: DCD never involves losing mastered skills, while Rett does, and any loss of skills needs prompt paediatric and genetic assessment rather than therapy alone. *Both can affect how a child moves — but one is a coordination difference a child grows up learning to manage, and the other is a rare genetic condition with a very different course.* ## In short **Developmental Coordination Disorder (DCD)** — sometimes called dyspraxia — is a difference in how a child plans and coordinates movement: they may be clumsier than expected, struggle with buttons, cutlery, running or handwriting, despite normal intelligence and no underlying disease. **Rett syndrome** is a rare genetic neurodevelopmental condition (almost always in girls) caused by a change usually in the *MECP2* gene, where a child develops typically for the first 6–18 months and then *loses* skills she had gained — especially purposeful hand use and sometimes speech. The key difference: DCD is a stable coordination difficulty a child gradually improves with support; Rett involves a regression — a loss of skills already mastered — and needs prompt paediatric and genetic assessment. ## How they differ in everyday life In **DCD**, a child has always found certain motor tasks hard — they don't lose skills, they're just slower to master them. You might notice tripping, dropping things, messy handwriting, difficulty with bikes or buttons, or trouble keeping up in sport. Language and thinking are usually unaffected, and with occupational and physiotherapy these children make steady, encouraging progress. In **Rett syndrome**, the pattern is one of *change over time*. After an early period of seemingly typical development, a young girl may slow down or go backwards — losing purposeful hand movements and replacing them with repetitive hand-wringing or hand-to-mouth movements, losing words she once used, showing slowing head growth, and sometimes developing walking difficulties or seizures. This regression pattern is the signal that distinguishes it from a simple coordination difference. ## When to seek help If your child has *always* been a little clumsy but is otherwise learning, growing and chatting well, a developmental and occupational-therapy review is the right route — there's no urgency, only support. But if your child has **lost** skills she previously had — stopped using words, stopped using her hands purposefully, or her head has stopped growing as expected — please see a paediatrician promptly, as this needs medical and genetic evaluation, not therapy alone. ## 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 clinicians observe how your child moves, plays and communicates, and chart whether skills are emerging steadily or changing over time, then guide you to the right support — from [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) for coordination to coordinated medical referral when a pattern of regression is seen.
