Early Decline Detection
"What changes should I pay attention to — before a health crisis occurs?"
Health rarely changes overnight. It drifts — a missed dose, a skipped walk, a quieter weekend — until small shifts add up to a fall, a hospitalization, or a diagnosis that feels sudden but wasn't. Horizon Signals gives the people closest to an aging loved one a structured way to notice that drift early enough to act on it.
Horizon Signals isn't written for clinicians reading a chart. It's written for the people who see a person, not a patient — often weeks or months before any of this reaches a doctor's office.
You see your parent every few weeks and sense something's different — even if you can't quite name it yet.
You're in the home regularly and notice the small stuff that never makes it into a 15-minute appointment.
You see many residents every week and need a fast, shared language for "something has changed."
You're often the first to notice a change between a family's visits — and the first they'll ask.
Three short steps. No login, no diagnosis, no data leaving this page.
Think back over the past few weeks — not just today — across six everyday areas where decline tends to show up first.
Work through the Signal Check below. Check anything that's true now, or that's become true recently.
Bring your Signal Reading to a healthcare conversation — not as a diagnosis, but as a place to start one.
Six areas, four questions each. Check anything that applies — your Signal Horizon below updates as you go.

All quiet, for now.

Horizon Signals is an awareness tool, not a diagnostic instrument. It does not replace a comprehensive geriatric assessment, clinical judgment, or a conversation with a licensed healthcare professional. If you're concerned about an immediate safety risk, don't wait for a routine visit — contact a healthcare provider or local emergency services now.
Horizon Signals isn't a single stop along the care journey — it's the layer underneath all of them. It's built to catch the moment someone starts moving from one stage to the next, long before that shift becomes a crisis.
Preventive health conversations
Care transition & navigation
Values-based advance care planning
Hospice readiness & eligibility
Each of the six areas in the Signal Check is informed by an established line of geriatric and caregiving research, translated into plain, everyday language: fall-risk frameworks in the tradition of the CDC's STEADI initiative; frailty phenotypes such as PRISMA-7 and the Fried frailty model, which treat slowness and reduced strength as early physical markers; the clinical convention that a 5% weight loss in one month, or 10% over six months, is significant regardless of cause; geriatric polypharmacy research describing five or more regular medications as a recognized risk threshold; informant-based cognitive screening, in the spirit of tools like the AD8, which rely on someone close to the person noticing change; and population research from the National Institute on Aging and the National Academies of Sciences linking social isolation and loneliness to measurable physical health decline.
Horizon Signals is not a substitute for any of these validated clinical instruments, and a flagged signal is not a diagnosis. It is designed to prompt a conversation, not to replace one.
