Rett Syndrome is a rare genetic neurodevelopmental condition, almost always in girls, with a distinct pattern of early typical development followed by loss of purposeful hand use, slowing head growth and repetitive hand movements. EBD is about coping and behaviour; Rett is a specific medical diagnosis defined by regression. The key signal for Rett is losing skills a child once had, which warrants prompt medical review.","answer_md":"*Two very different journeys are sometimes confused — one is about how big feelings show up in behaviour, the other is a rare genetic condition with a recognisable pattern.*\n\n## In short\n**Emotional & Behavioural Difficulties (EBD)** describe a child who struggles to manage feelings and behaviour — big tantrums, anxiety, withdrawal or defiance that go beyond the usual ups and downs of childhood. **Rett Syndrome** is a rare genetic neurodevelopmental condition (almost always in girls, caused by a change in the *MECP2* gene) marked by a distinct pattern: a period of typical early development followed by a loss of purposeful hand use, slowing head growth and emergence of repetitive hand movements. EBD is about *how a child copes and behaves*; Rett is a specific medical diagnosis with a predictable regression pattern. The two rarely overlap — but because both can show changes in mood and behaviour, parents sometimes wonder which they are seeing.\n\n## How they differ\nThe clearest difference is in the **story over time**. With EBD, a child's core abilities — walking, using their hands, understanding — keep developing; what struggles is the *regulation* of emotion and behaviour, often in response to stress, environment, communication frustration or temperament. With support and consistency these patterns can settle markedly.\n\nRett Syndrome follows a very different and recognisable arc. After roughly 6–18 months of apparently typical growth, a child shows a **regression** — losing skills they once had, especially purposeful hand use, which is gradually replaced by repetitive hand-wringing, washing or mouthing movements. Head growth often slows, and there may be changes in walking, breathing rhythm and communication. This is a neurological pattern, not a behavioural one, and it warrants prompt medical and genetic review.\n\nA simple way to hold it: in EBD, the question is *\"why is my child finding feelings and behaviour so hard?\"* In Rett, the question is *\"why is my child losing skills they used to have?\"* That word — **losing** — is the signal to seek medical advice quickly.\n\n## When to seek review\nSeek a prompt review if you notice **loss of skills a child once had** — hands that no longer reach, grasp or point as before, repetitive hand movements, slowing head growth, or changes in walking. This is a medical priority. For ongoing struggles with big feelings, anxiety, meltdowns or defiance that disrupt daily life — without loss of skills — a developmental and emotional review helps understand what your child needs.\n\n## The Pinnacle way\nThis 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 can gently map your child's emotional and developmental profile through [behavioural therapy](/behavioural-therapy) and family support, and guide medical referral where a condition like Rett is suspected. You can explore more about [emotional & behavioural difficulties](/emotional-behavioural-difficulties) and how we support each child as a whole.\n\n## Trusted sources\nWHO ICD-11 framing of neurodevelopmental and emotional-behavioural conditions; the American Academy of Pediatrics and HealthyChildren on developmental regression and emotional development; CDC milestone guidance on when loss of skills warrants prompt review.\n\n**Next step —** If your child is losing skills they once had, seek a medical review without delay; if big feelings and behaviour are the worry, book a developmental review to understand and support them early.","canonical":"https://pinnacleblooms.org/ask/what-is-the-difference-between-emotional-and-behavioural-difficulties-and-rett-syndrome-in-young-children","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU Consortium · Pinnacle Blooms Network"},"alternates":[{"href":"https://pinnacleblooms.org/ask/what-is-the-difference-between-emotional-and-behavioural-difficulties-and-rett-syndrome-in-young-children","lang":"en","indexable":true}],"dimensions":[],"meta_title":"EBD vs Rett Syndrome in Children: The Difference","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Keep a simple dated note of skills your child has gained — first claps, points, finger-feeding.
