Scam Safety for People With Dementia
Supportive guidance for families and carers helping protect someone with dementia from scams — while preserving dignity and independence.
Last reviewed: 1 June 2026
People living with dementia can be particularly vulnerable to scams because of changes in memory, judgement, and the ability to spot deception. At the same time, they deserve to be treated with full dignity, and their autonomy should be respected as far as possible. The goal is to put gentle, practical protections in place alongside the person — not to take over — working with their strengths and involving their care network where appropriate.
Why dementia increases scam risk
Dementia can affect short-term memory, making it hard to recall a recent conversation with a scammer or notice that the same story has been told before. It can also reduce the ability to read social cues and detect deception, and make it harder to recognise a familiar voice or face convincingly imitated over the phone. None of this reflects poor judgement or a personal failing — it's a medical reality of how the condition affects the brain, and scammers deliberately target people with cognitive decline precisely because these vulnerabilities make manipulation easier and repeat targeting more likely. Understanding this helps families respond with practical protection and patience rather than frustration when the same scam attempt happens more than once.
- Memory gaps can mean a scammer sounds plausible across multiple calls
- Reduced judgement can make urgency and authority harder to evaluate
- Loneliness or isolation can make social contact from any source feel welcome
Practical protections to put in place
The most effective approach focuses on reducing how often a scam contact reaches the person at all, and limiting the damage if one does get through. Registering their number with a call-blocking or nuisance-call screening service cuts down significantly on cold calls, which are the entry point for most scams. Setting a low daily spending limit on their bank card, or moving to an account with transaction alerts sent to a trusted family member, adds a financial safety net that doesn't require removing their independence. Removing their details from data broker and marketing lists reduces how easily their name and situation can be found by scammers. Introduce each change gently, one at a time, and explain simply why it helps rather than presenting it as a restriction.
- Register with the Telephone Preference Service and use a call-blocking device
- Set up a trusted-contact alert with their bank
- Arrange for a carer or family member to review post and calls periodically
- Keep a written 'pause and check' reminder near the phone
- Consider a Lasting Power of Attorney (LPA) or equivalent if not already in place
Supporting without removing independence
It's natural to want to take over everything once you're worried about a parent's safety, but the aim here is to add protective layers, not to strip away their sense of control over their own life. Wherever their capacity allows, involve them directly in decisions: sit down together and say, 'I'd like us to set up alerts on your account so we both know if something unusual happens — does that sound okay?' rather than making the change unilaterally. Explain simply why each measure helps, using a real example of a scam it would have stopped. If a change does need to happen without full agreement due to advancing dementia, keep it as light-touch as possible and revisit it regularly rather than treating it as permanent and unquestionable.
- Frame protections as 'scams are everywhere — we all use these'
- Involve them in setting up protections where they're able
- Check in regularly with warmth, not interrogation
- Coordinate with their formal care team if one is in place
Frequently asked questions
Should I set up Power of Attorney?
A Lasting Power of Attorney (LPA) — or its equivalent in your country — allows a trusted person to help manage finances if capacity is lost. It can only be set up while the person still has mental capacity, so acting early is important. A solicitor or the Office of the Public Guardian can advise.
How do I tell the bank about the situation?
Most banks have a dedicated vulnerability or third-party access process. You can usually request a trusted-contact arrangement, lower daily transaction limits, or a joint account flag. The bank won't share information about the account but can apply safeguards and act on concerns you raise.
What if they become angry when I try to help?
Resistance is common and understandable — no one wants to feel their independence is being removed. Take a step back, give it time, and try again more gently. Focus on one small measure at a time and involve their GP or care team for advice on the best approach.
