How to Keep Someone With Dementia Safe

Quick answer

How to keep someone with dementia safe: change the environment rather than relying on them to remember, plan for walking about before it happens, take medicines out of their hands gently but properly, and make sure their medical information is carried on them — because in an emergency they may not be able to tell anyone what they take or what they are allergic to.

Dementia Australia estimates around 446,500 Australians are living with dementia. Most of them live in the community, and most of the safety work is done quietly by family.

The goal is not to remove risk entirely — that usually means removing independence too. It is to change the things that can be changed, so the person keeps as much ordinary life as possible.

What actually changes, and why it matters for safety

Dementia affects more than memory, and the other changes are the ones that catch families out.

Judgement and sequencing — a task with several steps, like cooking, becomes hard to complete safely even when each step is familiar.
Perception — depth, contrast and patterns can be misread. A dark mat may look like a hole; a shiny floor may look wet.
Communication — the ability to describe pain or symptoms can go before the ability to hold a conversation.
Time and place — a familiar route can stop being familiar without warning.

The practical implication is consistent: reminders and instructions stop working long before the environment stops mattering. Change the setting rather than expecting recall.

Making the home safer

Falls, which are the commonest harm

Remove loose rugs and trailing cords rather than tidying around them.
Improve lighting, especially between bed and bathroom, with sensor night lights.
Use contrasting colours — a toilet seat or plate that stands out from its background is easier to see.
Grab rails in the bathroom, and a non-slip mat in the shower.
Keep everyday items in reach so there is no climbing.

Kitchen

Consider an isolation switch or removable knobs for the stove.
Set the hot water thermostat to reduce scald risk.
Check the fridge regularly — use-by dates stop being noticed.
Keep an eye on the kettle and toaster; automatic cut-off appliances help.

Everything hazardous

Medicines, cleaning products, alcohol and tools stored out of sight rather than merely out of reach.
Working smoke alarms, tested; consider a model designed for people who are hard of hearing.
If there are firearms in the house, they must be secured to the standard the law requires and the situation warrants.

Walking about, and going missing

Leaving the house and becoming lost — often called walking about — is one of the most frightening scenarios for families, and it is best planned for before it happens rather than after.

Prepare in advance

Keep a current photograph and a written description of what they usually wear.
Make sure they carry identification with a contact number that stays on them — something worn works better than something in a pocket.
Note the places they might head for: a former home, a workplace, a church, a shop.
Tell trusted neighbours and nearby shops, so someone recognises them.
Consider a location-tracking device if it is acceptable to the person and discussed openly.

If they are missing

Call the police straight away. Do not wait 24 hours — that rule does not apply, and it particularly does not apply to a person living with dementia, who is a vulnerable missing person. Search the immediate area while someone else makes the call, and have the photograph ready.

Medicines

Managing medicines is one of the first things to become unsafe, and one of the hardest to take over without a fight, because it feels like a loss of independence.

Ask the pharmacy about a packed blister or sachet arrangement, which removes the sorting step.
Store the supply elsewhere and hand over each dose, rather than leaving boxes accessible.
Watch for double-dosing — a common and easily missed risk.
Book a medicines review with the GP; the list is often longer than it needs to be. See how to manage your medication.

Driving

Driving is often the hardest conversation. A dementia diagnosis does not automatically end it, but it does create an obligation: in every Australian state and territory, drivers must report medical conditions that may affect driving to the licensing authority, and fitness to drive is assessed medically. Requirements differ by jurisdiction, so check with your state or territory authority and the GP.

Where it is possible, framing it around a medical assessment rather than a family decision usually causes less conflict — and arranging alternative transport in advance makes the change practical rather than punitive.

Preparing for a medical emergency

This is the part that gets least attention and matters most. Someone with dementia may not be able to say what they take, what they are allergic to, or what happened — and those are precisely the things a responder cannot work out by looking. We covered that in what emergency responders look for.

Make sure it exists	Why
A written, current medication list	They cannot recite it, and family may not be present
Allergies with the reaction	Changes what is safe to give
The dementia diagnosis itself	Confusion is then understood as baseline, not a new event
Contacts, in call order	Someone who knows the history can be reached fast
Something worn that carries it	Bags, wallets and phones get separated from people

Recording the diagnosis matters more than families expect. A person who is disoriented in an emergency department may otherwise be investigated for a sudden change in mental state that is, for them, entirely normal.

They may not be able to explain. The band can.

A MedibandPlus profile keeps their diagnosis, medications, allergies and your contact details readable from a membership number worn on the wrist — no app, no login.

Technology that genuinely helps

Automatic pill dispensers with a lockable timer.
Sensor lights on the route to the bathroom.
Simplified phones with photo buttons for key contacts.
Personal alarms for falls, if the person will wear one.
Location tracking, discussed openly rather than installed secretly — the relationship matters more than the device.

Introduce anything new early, while learning a new habit is still possible. A device introduced late is often rejected.

Looking after yourself

Carer exhaustion is a safety issue, not a side note — tired people miss things. Carer Gateway is the national starting point for practical help, counselling and respite, and Dementia Australia runs the National Dementia Helpline on 1800 100 500.

FAQs

How do you keep someone with dementia safe at home?

Change the environment rather than relying on the person to remember. Remove trip hazards, improve lighting between bed and bathroom, use contrasting colours so fixtures are easier to see, fit grab rails, make the stove safe with an isolation switch or removable knobs, and store medicines and chemicals out of sight rather than merely out of reach.

What should I do if a person with dementia goes missing?

Call the police straight away. There is no 24-hour waiting rule, and it particularly does not apply to someone living with dementia, who is treated as a vulnerable missing person. Search the immediate area while someone else calls, and have a current photograph and a description of their clothing ready.

How can I prepare for walking about before it happens?

Keep a current photo and a note of what they usually wear, make sure they carry identification with a contact number that stays on them, list the places they might head for such as a former home or workplace, tell trusted neighbours and nearby shops, and consider a location device discussed openly with the person.

Can someone with dementia keep driving?

A diagnosis does not automatically end driving, but in every Australian state and territory drivers must report medical conditions that may affect driving to the licensing authority, and fitness to drive is medically assessed. Requirements differ by jurisdiction, so check with your state or territory authority and the GP. Framing it as a medical assessment usually causes less conflict.

How do I manage their medicines safely?

Ask the pharmacy about a packed blister or sachet arrangement so there is no sorting step, keep the supply stored elsewhere and hand over each dose rather than leaving boxes accessible, watch for accidental double-dosing, and book a medicines review with the GP, since the list is often longer than it needs to be.

Why record a dementia diagnosis for emergencies?

Because confusion is then understood as their baseline rather than a sudden change. A disoriented person in an emergency department may otherwise be investigated for an acute change in mental state that is, for them, entirely normal. It also means responders know the person cannot reliably give their own history.

Where can carers get support in Australia?

Carer Gateway is the national starting point for practical help, counselling and respite. Dementia Australia runs the National Dementia Helpline on 1800 100 500 for information and support. Carer exhaustion is a safety issue rather than a side note, because tired people miss things, so arranging help early is part of keeping the person safe.
