Medical Alert Systems for Dementia

That is the whole argument of this page, and most buying guides skip it. They rank medical alert systems for a parent with dementia using the same criteria they use for a parent with arthritis, as though the help button works the same way in both cases. It does not. Below is what the button assumes, what dementia can remove, which features survive that, and what the Alzheimer's Association says to do when someone goes missing.

A monitored medical alert system is a chain, and every link in it is an assumption about the wearer. The wearer notices the emergency. The wearer remembers the pendant. The wearer is still wearing the pendant. The wearer presses it and can talk to the operator. Dementia can break any of those links, and often breaks several at once.

None of that makes a monitored system worthless. In early dementia, with a familiar routine and a device the person is used to wearing, the button can still bring help. It does mean the button should not be the reason you choose one system over another. The feature to compare is the one that works while your parent does nothing at all.

The Alzheimer's Association states that six in ten people with Alzheimer's disease will wander. Getting lost can happen at any stage, and wandering behavior often occurs during the middle stage. The reassuring part of the same guidance is that most wanderers are found within a half mile of their home or starting location.

Read those two facts together and you get the practical case for location tracking. The person is usually close by. The problem is knowing which direction, and how long ago. That is a question a caregiver app can answer in seconds and a search on foot can take an hour to answer.

Reorder the usual checklist. For dementia, the features that work without any action from the wearer come first, and the features that depend on the wearer come last.

• Caregiver location tracking. A current location and a location history, visible from a phone. This is the one feature that does its job whether or not your parent understands the device.
• Automatic notification when the person leaves a familiar place. The Alzheimer's Association lists smartphone apps that can notify a caregiver when the person leaves a familiar area. An alert is what shortens the gap between someone leaving and someone noticing.
• Wearability, and how hard it is to take off. The Alzheimer's Association also lists wearable GPS trackers including watches and shoe inserts. A tracker in a shoe insert is a tracker that stays on the person, which is why it appears on that list at all.
• Battery life and charging. A device that needs a daily charge needs a caregiver to charge it daily. Build that into the plan rather than hoping.
• The help button. Worth having and worth practising. Do not let it decide the purchase.

If fall risk is also a concern, our guide to how fall detection works explains what that feature does and where it falls short. Treat it as a separate question from wandering.

We checked Bay Alarm Medical's own pricing page on 17 September 2026 because it is one of the providers that puts caregiver tracking in front of the buyer rather than burying it. Two of its mobile devices carry the feature: the SOS Micro at $34.95 a month and the SOS Smartwatch at $39.95 a month. Both list GPS Caregiver Tracking, which Bay Alarm describes as: “Check in on mom's current location in real-time and access her location history with our Caregiver Tracking app.”

That sentence is doing the work on this page. Checking a current location and scrolling back through a location history are caregiver actions. They do not require your parent to press, remember, or explain anything. The watch also, in Bay Alarm's words, “utilizes a physical help button + GPS to dispatch local EMS to your location,” and when the button is pressed the wearer reaches a US-based emergency center through a two-way speaker, where the operator contacts 911 or a family member.

We have not tested either device. This is what the provider publishes about its own product, which is the standard we hold ourselves to. See our Bay Alarm Medical review for the wider plan picture, our medical alert watch comparison for wrist-worn options, and the cost comparison for how those monthly figures sit against the rest of the market.

Not among the products we checked. None of the providers describes its system as designed for dementia, so we are treating these as general GPS medical alert systems that happen to include a caregiver-tracking feature worth having. If a salesperson tells you a device is built for dementia, ask them to show you where the manufacturer says so in writing. Marketing that leans on a diagnosis is a reason to read more slowly.

The Alzheimer's Association frames location tracking as one of many ways to help someone with dementia stay safe, sitting inside a broader safety plan. That framing is worth taking literally. A tracker tells you where someone went. It does not notice they left, unless something alerts you, and it does not bring them home.

• Know who is with your parent, and when nobody is. Most wandering happens in the gaps.
• Write down the neighbours, nearby businesses and former addresses a person might walk toward, and keep the list with the photo.
• Make the exits harder to use without thinking, and keep car keys somewhere that requires a decision.
• Agree in advance who calls 911 and who searches, so the 15-minute rule is not a debate held in a driveway.
• Revisit the plan as the condition changes, because the middle stage brings risks the early stage did not.
• Talk to the person's clinician about the medical picture. This page is general information from published sources and is not medical advice.
