An AbilityScore® of 400–500 is a baseline, not a verdict — a Pinnacle clinician turns it into a focused, re-measured plan. Only a centre forms a clinical score or diagnosis.","answer_md":"*When your child's skills have slipped and you're holding a number between 400 and 500, you need a clear next step — not more worry. Here it is.*\n\n## In short\nA [Developmental Regression](/) — losing skills your child once had, whether words, play, social warmth or movement — always deserves prompt medical attention first, before therapy planning. An AbilityScore® in the **400–500 band** is one structured snapshot of where your child is right now; it is a baseline to build from, not a verdict. Your next step is a doctor-led review to rule out treatable causes, followed by a Pinnacle clinician turning that baseline into a focused plan.\n\n## What to do next, in order\n1. **See your paediatrician promptly.** Any genuine *loss* of skills — especially sudden loss, or loss with seizures, unsteadiness or unusual movements — needs a medical review to check for treatable and time-sensitive causes. This comes first.\n2. **Bring your evidence.** Note *what* was lost, *when* it started, and *how quickly*. Old videos of your child babbling, playing or walking are genuinely valuable to the clinician.\n3. **Turn the baseline into a plan.** The 400–500 AbilityScore® gives your Pinnacle clinician a precise starting point across communication, play, motor and daily-living skills — so therapy targets exactly what slipped, and progress is re-measured against *your child's own* baseline, not another child's.\n4. **Start early, review often.** Development moves in spurts and plateaus; structured re-measurement shows whether a pause is normal or needs a change of approach.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online number alone. With 2.5 billion+ data points and 25 million+ therapy sessions behind it, the AbilityScore® is a clinician-administered structured assessment that maps your child's strengths and next steps. Explore [how the AbilityScore® is calculated](/ask/what-is-the-abilityscore-and-how-is-it-calculated), our [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) and [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) pathways, and start at [Developmental Regression](/).\n\n## Trusted sources\nWHO and ICD-11 guidance on developmental disorders; American Academy of Pediatrics developmental surveillance advice; ASHA on communication regression; Pinnacle Blooms Network clinical studies.\n\n**Next step —** Regression is a reason to act calmly and quickly. See your paediatrician first, then [book an assessment](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) so your 400–500 baseline becomes a clear, hopeful plan.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/my-child-with-developmental-regression-has-an-abilityscore-of-400-500-what-should-we-do-next","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/my-child-with-developmental-regression-has-an-abilityscore-of-400-500-what-should-we-do-next","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/my-child-with-developmental-regression-has-an-abilityscore-of-400-500-what-should-we-do-next-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Regression & AbilityScore 400–500: Next Steps","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Keep a short dated log and short videos of your child's play, sounds and movement.
