These describe what you are noticing, not a diagnosis. Any true loss of a skill a child once had deserves a prompt developmental check, and sudden loss needs same-day medical review.","answer_md":"*When a child quietly loses a skill they once had, every parent wants to understand what kind of change they are seeing — and what it might mean.*\n\n## In short\nDevelopmental regression isn't one single thing — it is described by **which area of development is affected** and **how it unfolds**. Most often it is grouped by domain (such as language, social, motor or self-care) and by pattern (a slow fading versus a sudden, clear loss). These are ways of describing what you are noticing — not diagnoses in themselves. Any genuine loss of a skill your child once had is always worth a prompt developmental check.\n\n## The common ways regression is described\n**By the area (domain) affected**\n- **Language regression** — losing words, babble or the back-and-forth of early talking.\n- **Social regression** — pulling back from eye contact, smiles, pointing or playing with others.\n- **Motor regression** — losing movement skills such as sitting, walking, or hand use.\n- **Self-care / adaptive regression** — losing skills like feeding, dressing or toileting that a child had managed.\n- **Cognitive regression** — slipping in attention, play or problem-solving that was previously age-typical.\n- **Global regression** — when several areas are affected together.\n\n**By the pattern over time**\n- **Gradual** — skills fade slowly over weeks or months.\n- **Sudden or acute** — a clear, noticeable loss over days, which warrants quicker medical review.\n- **Plateau-then-loss** — progress stalls first, then a skill is lost.\n\nIt also helps to separate true regression (a real, sustained loss) from a temporary dip around illness, a new sibling, a house move or disrupted sleep — these often recover on their own. A clinician's job is to tell these apart.\n\n## When to seek a check\nReach out promptly for **any** loss of speech, social connection or movement at any age — and especially if the change is sudden, comes with seizures, unusual movements, or a clear loss of alertness, which need same-day medical attention. You never need to be certain before asking; describing what you have noticed is enough.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment.
