{"h1":"Hearing Impairment vs Rett Syndrome in Young Children","faq":[{"a":"No. Hearing impairment slows the development of skills that depend on hearing, like speech, but it does not take away abilities a child already had. If your child is losing skills she once had — such as hand use or words — that is a different concern and needs prompt medical review.","q":"Can hearing impairment cause a child to lose skills she already had?"},{"a":"Rett syndrome is almost always seen in girls, as it is linked to a gene on the X chromosome. It is very rare in boys. A geneticist and paediatric neurologist confirm it through clinical evaluation and genetic testing.","q":"Does Rett syndrome only affect girls?"},{"a":"Hearing impairment shows as not responding to sound while the child otherwise plays, points and uses her hands well. Rett syndrome shows a pattern of regression — losing words and purposeful hand use, often with hand-wringing movements. A clinician can distinguish these; don't try to decide alone.","q":"How can I tell which one my child might have?"},{"a":"Book a developmental check with your paediatrician. They can arrange a hearing assessment and, if a pattern of regression is present, refer to paediatric neurology. Early evaluation gives your child the best support.","q":"What is the first step if I'm worried?"}],"lang":"en","slug":"what-is-the-difference-between-hearing-impairment-and-rett-syndrome-in-young-children","title":"Hearing Impairment vs Rett Syndrome in Young Children","entity":{"key":"hearing","kind":"condition_vs_condition","name":"Hearing Impairment vs Rett Syndrome","slug":"hearing-impairment"},"lenses":[{"kind":"stakeholder","label":"Parent","value":"parent"},{"kind":"domain","label":"Sensory","value":"sensory"},{"kind":"intent","label":"Definition","value":"definition"},{"kind":"lifecycle","label":"Screen","value":"screen"},{"kind":"route","label":"Book-Assessment","value":"book-assessment"},{"kind":"empowerment","label":"Early Clarity","value":"early_clarity"}],"parent":null,"related":[{"lang":"en","slug":"what-is-the-difference-between-dyslexia-reading-impairment-and-rett-syndrome-in-young-children","title":"Dyslexia vs Rett Syndrome in Young Children"},{"lang":"en","slug":"what-is-the-difference-between-developmental-regression-and-rett-syndrome-in-young-children","title":"Developmental Regression vs Rett Syndrome in young children"},{"lang":"en","slug":"what-is-the-difference-between-rett-syndrome-and-social-communication-difficulties-in-young-children","title":"Rett Syndrome vs Social Communication Difficulties in Young Children"},{"lang":"en","slug":"what-is-the-difference-between-rett-syndrome-and-speech-and-language-delay-in-young-children","title":"Rett Syndrome vs Speech and Language Delay"},{"lang":"en","slug":"what-is-the-difference-between-developmental-regression-and-hearing-impairment-in-young-children","title":"Developmental Regression vs Hearing Impairment"},{"lang":"en","slug":"what-is-the-difference-between-non-verbal-minimally-verbal-presentation-and-rett-syndrome-in-young-children","title":"Minimally Verbal vs Rett Syndrome in Young Children"}],"summary":"Hearing impairment is a sensory barrier — the ears or hearing pathways don't pick up sound fully, so speech and language are delayed while the rest of development is typical, and it never removes skills a child already had. Rett syndrome is a rare genetic neurodevelopmental condition, almost always in girls, marked by a clear pattern of regression after 6–18 months of typical development: loss of purposeful hand use and words, plus distinctive hand-wringing movements. One slows skills that depend on hearing; the other takes away skills already gained and needs prompt medical and genetic evaluation.","answer_md":"*Two very different things can both look like a child who isn't responding to their name — one is about how sound reaches the brain, the other about how the whole nervous system develops.*\n\n## In short\n**Hearing impairment** means a child's ears or hearing pathways don't pick up sound fully — so speech and language are delayed because the child simply isn't hearing words clearly. **Rett syndrome** is a rare genetic neurodevelopmental condition (almost always in girls) where a child develops typically for the first 6–18 months, then *loses* skills she once had — especially purposeful hand use and spoken words — and develops distinctive hand-wringing movements. In short: hearing impairment is a *sensory* barrier to sound; Rett syndrome is a *whole-development* condition with a tell-tale pattern of regression.\n\n## How they differ in everyday life\nWith **hearing impairment**, a baby may not startle at loud sounds, may not turn towards your voice, and speech may be slow to arrive — but the child is otherwise alert, uses her hands well, points, plays and engages with her eyes and gestures. Crucially, hearing loss does *not* take away skills a child already had; it slows the skills that depend on hearing. Many forms are picked up at newborn hearing screening and managed effectively with hearing aids, cochlear implants and speech support.\n\nWith **Rett syndrome**, the hallmark is *regression* — a little girl who was babbling, reaching and using her hands begins to lose those abilities, often between 1 and 4 years. Purposeful hand use fades and is replaced by repetitive hand-wringing, washing or mouthing movements. Head growth may slow, walking can become unsteady, and breathing patterns may be irregular when awake. This is a medical-genetic condition that needs prompt paediatric and neurology referral, not therapy alone.\n\n## When to seek help\nSee your paediatrician promptly if your child does not respond to sounds or voices, or failed the newborn hearing screen — a hearing assessment is the clear next step. Seek urgent medical review if your child *loses* skills she once had (hand use, words, walking) or develops repetitive hand movements — this pattern always warrants specialist evaluation. Either way, an early developmental check protects your child's progress.\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.
