Dementia, Alzheimer's, and Falls: The Hidden Home Danger

In the earlier stages of dementia, many people still live independently — and face a raised risk of falling. A safety net that notices and reaches out fits a condition where remembering to call for help can't be assumed.

Adults with Alzheimer's disease have a 43.55% annual fall prevalence, averaging 1.30 falls per person per year (Simpkins, Mahmoudzadeh Khalili & Yang, Advances in Geriatric Medicine and Research, 2024) — well above the roughly one-in-four rate in the general older population.

The Challenge

Dementia affects judgment, spatial awareness and gait, roughly doubling the number of falls per person

After a fall, a person with cognitive impairment may not remember how — or think — to call for help

Wandering and disorientation can lead to falls in unfamiliar or hazardous spots

Families worry constantly but can't watch over a loved one around the clock without ending their independence

How I'm Alive Helps

A free daily check-in creates a simple daily signal; a missed check-in alerts family without the person needing to make a call

Check-first phone fall detection (coming to the app) notices a hard fall and alerts trusted contacts with a location if there's no response

No wearable to remember or resist — detection runs on the phone already carried, and family are the ones alerted

Alerts go to chosen family, not 911, so responses are handled by people who know the person and their needs

Why dementia raises fall risk

Dementia affects more than memory. It can impair judgment, spatial awareness, attention and gait, and it often coexists with the physical changes of ageing — all of which raise the risk of falling. Adults with Alzheimer's disease have a 43.55% annual fall prevalence and average 1.30 falls per person per year (Simpkins et al., 2024), well above the roughly one-in-four annual rate in the general older population. Crucially, cognitive impairment also changes what happens after a fall. A person may not remember how to call for help, may not recognise that they need it, or may become disoriented — so the response gap that affects everyone living alone is wider still.

The response gap is wider with cognitive impairment

For anyone living alone, the danger of a fall is often the time spent on the floor before help arrives. Most falls happen with no one present — 82% of falls in adults 90+ occurred when the person was alone, and 30% of fallers lay on the floor for an hour or more (Fleming & Brayne, BMJ 2008). About half of older home-fallers who had a long lie died within six months (Wild et al., BMJ 1981), and mortality among people found helpless at home rose from 12% within an hour to 67% after more than 72 hours (Gurley et al., NEJM 1996). When a fall is layered on top of dementia, the assumption that the person will call for help can't be made — which is why a safety net that works without requiring a call is a better fit for the condition.

Where check-first fall detection and daily check-in fit

For someone in the earlier stages of dementia living alone, the free daily check-in is often the most valuable layer, because it turns a missed daily tap into an alert to family — no phone call, no button-pressing, no memory required. Alongside it, check-first phone fall detection is coming to the I'm Alive app in our next update (v2.3.0): it detects a hard fall, checks on the person first, and — if there's no response — alerts the trusted contacts you set up, with a location. It runs on the phone (no pendant or smartwatch), it is opt-in and off by default, and it never calls 911. It is best-effort, not a medical device, and does not diagnose or treat dementia. It is included from the Protect Me plan ($29.99/year). Alerts go to family who know the person — not to a call center or emergency services — so the response can be shaped around their needs. This is a support for families managing early-stage dementia at home, not a replacement for a care plan or clinical supervision, and it is not designed for someone who can no longer safely live independently.

Frequently Asked Questions

Do people with dementia fall more often?

Yes. Adults with Alzheimer's disease have a 43.55% annual fall prevalence and average 1.30 falls per person per year (Simpkins et al., 2024) — well above the roughly one-in-four rate in the general older population.

Why is a fall more dangerous for someone with dementia living alone?

Because cognitive impairment can mean the person doesn't remember how, or think, to call for help — widening the response gap. Most falls happen when the person is alone (82% in adults 90+; Fleming & Brayne, BMJ 2008), and mortality rises steeply with time to discovery (Gurley et al., NEJM 1996).

How does a daily check-in help with early dementia?

It turns a missed daily tap into an alert to family — no phone call, no button-pressing and no memory required. It's often the most valuable layer for someone in the earlier stages of dementia living alone.

Does the app call 911 for a person with dementia?

No. It alerts the family contacts you set up, who know the person and their needs, so the response can be shaped for them. In a life-threatening emergency, a contact or caregiver should call 911 directly.

Is this a substitute for dementia care?

No. It is a support for families managing early-stage dementia at home, not a replacement for a care plan or clinical supervision, and it is not designed for someone who can no longer safely live independently. Fall detection is best-effort and coming to the app in v2.3.0.
