“My purse is gone. Someone has taken it.” For families, these words can sting. Suspicion and accusations are a common symptom of dementia, and both the Alzheimer’s Association and the Alzheimer’s Society recognise them as part of the condition. They usually begin when memory loss stops an elder from retracing where an item was left, so the mind fills the gap with an explanation that feels true: someone must have taken it. In some elders, these ideas become fixed false beliefs, known as delusions, which cannot be reasoned away. What matters most is that the accusation comes from the condition and is not a judgement on the person accused. This guide explains why it happens, what triggers it, what it may be telling you, how to calm your elderly loved one, and how dementia specialists can help.
Why does dementia cause suspicion and false accusations?
Dementia changes memory and the way the brain makes sense of events, so an elder who cannot find something may decide someone took it - this can be called dementia paranoia, and it is a symptom of the condition, not a flaw in your loved one’s character. The Alzheimer’s Association and the Alzheimer’s Society state that in dementia, false accusations and suspicion are common experiences for families.
- Memory loss: areas of the brain that help form and store new memories, such as the hippocampus, are often affected early in Alzheimer’s disease. Your loved one may put a wallet away safely, yet the memory of doing so is never stored, so they cannot retrace their steps. When the brain cannot find the missing information, it may fill the gap with an explanation that feels true, and “someone took it” can seem the most logical one.
- Reduced reasoning: the frontal areas of the brain help us plan, weigh up alternatives and check our own thinking. When they are affected, it becomes harder to consider other explanations, such as having simply misplaced the item, and harder to question a belief once it forms.
- Misreading situations: dementia can change how the brain interprets what the eyes and ears take in. A visitor moving near a cupboard, or a sound in another room, can be read as a threat. In some types of dementia, such as dementia with Lewy bodies, changes in visual perception are more common and can make this misreading more likely.
- Fear of losing control: the brain areas that help regulate emotion and anxiety can also be affected, so worries feel stronger and are harder to settle. Many elders also lose awareness of their own memory changes, so a missing item must be someone else’s doing. Money often stands for independence, so losing it can feel like losing a part of themselves.
To your elderly loved one, the belief is completely real. They are not trying to hurt you. They are trying to make sense of a world that no longer adds up.
What triggers suspicious behaviour, and what other reactions might you see?
Dementia suspicious behaviour is most often triggered by misplaced belongings, changes in routine or an unmet need, and it usually comes with strong emotions. Understanding the pattern helps you step in early.
- Misplaced items: keys, glasses, purses and documents are common starting points. Your elderly loved one may put something away carefully, forget where it went and be unable to retrace their steps. Because the memory has gone, the belief that someone took it feels like the only explanation.
- New people or changes: a new carer, a visitor or a rearranged room can unsettle an elder who relies on familiarity. When faces and surroundings no longer match what they expect, they may feel on guard, and suspicion can become a way of coping with that uncertainty.
- Tiredness and evening confusion: suspicion often grows as the light fades. Fading daylight and a long day can leave an elder more tired, more confused and less able to reason, so worries that seemed small in the morning can feel much bigger by the evening.
- Discomfort: pain, hunger, poor sleep or an infection can quietly increase agitation. Your elderly loved one may not be able to say what feels wrong, so the discomfort can come out as mistrust or irritability. If suspicion appears suddenly, it is worth checking comfort first.
You may also see hiding of valuables, repeated checking of drawers, anger, tearfulness or withdrawal. In some cases the beliefs grow firmer, such as thinking a stranger is in the house or that a spouse is being unfaithful. These are examples of delusions in dementia among elders, meaning fixed false beliefs that cannot be talked away with logic. Because a sudden change can have a medical cause, please mention it to your loved one’s doctor.
What might the accusation be telling you?
The accusation usually points to a feeling, such as fear, insecurity or loss of control, rather than a real judgement about the person accused. Listening for the feeling beneath the words can change how you respond.
- Fear and insecurity: feeling unsafe can show up as blaming someone nearby. When memory and understanding fade, the world can feel unpredictable, and an elder may look for a reason or a person to explain that uneasy feeling. The person accused is often the one closest, or the one most trusted.
- Loss of independence: managing money was once part of who they were, so its loss can be deeply unsettling. Paying bills, keeping a purse and making decisions were signs of capability, so a missing wallet can feel like losing a piece of their identity and not just an object.
- Unmet physical needs: pain, thirst or tiredness may be expressed as irritability and suspicion. An elder may not be able to say “my back hurts” or “I am hungry”, so discomfort comes out as mistrust or anger instead. Checking comfort first can sometimes ease the accusation itself.
- Confusion from change: a new routine or place can make everything feel unfamiliar and unsafe. A new carer, a moved piece of furniture or a visitor they do not recognise can all feel like a threat, and suspicion becomes a way of making sense of what has changed.
- A need for reassurance: sometimes the real message is simply, “I need to feel safe.” Beneath the words, your elderly loved one may be asking to be reassured that they are protected, that their belongings are secure and that someone is on their side.
When an elder with dementia who thinks someone stole money says so, they are often asking for comfort more than justice. Hearing this makes it easier not to take the words to heart.
How does it lead to misunderstanding, and how can you calm an elder?
Accusations can strain relationships, so the best response is to calm the feeling and not argue about the facts. Misunderstanding grows when families defend themselves, carers feel blamed or relatives drift away because the words hurt.
- Stay calm and speak softly: your tone matters more than your words. Your elderly loved one may not follow every sentence, but they read your voice, face and posture instantly. A slow, gentle tone tells them they are safe, which can lower their fear before it grows.
- Acknowledge the feeling: try “That sounds really worrying. Let’s look for it together.” Naming the emotion shows your elderly loved one that they have been heard, and feeling heard often eases the urgency more than any explanation.
- Avoid arguing or correcting: proving them wrong usually raises distress. Because the belief feels completely real to them, being told they are mistaken can feel like being dismissed, and it may deepen suspicion. Letting go of the need to be right protects your elderly loved one’s dignity and spares your family the exhaustion of repeated disagreements.
- Search together: joining the hunt shows you are on their side, and the item is often found. It turns you from the person under suspicion into a helper, which rebuilds trust. It also gives your elderly loved one a shared, purposeful task, and a found item brings quiet relief for everyone.
- Keep spare copies of everyday items: a spare purse or a small amount of money in a known place can end a search quickly. For your elderly loved one, having something to hold or check brings immediate reassurance, and the worry fades faster.
- Redirect gently: a cup of tea, a favourite song or a simple task can shift attention. Once the feeling has been acknowledged, a soothing activity gives your elderly loved one’s mind somewhere calmer to rest. It works best when it follows your reassurance, so the redirection feels like care and not a way of changing the subject.
If your loved one is very upset, or you feel overwhelmed, step away for a moment and ask another adult to help. Look after yourself too, because carers who feel supported respond with more patience. If accusations involve safety, such as a belief that someone is in the house, share this with the doctor.
How can professional care and dementia specialists help?
Dementia specialists look beyond the accusation to the whole person, from medical contributors to routines and surroundings. Their guidance can bring relief to your loved one and to you.
- Reviewing medical contributors: pain, infection, poor sleep or discomfort can quietly increase suspicion and agitation. A doctor or specialist can look for these causes, so your elderly loved one is not left suffering in silence, and your family gains a clearer picture of what is behind the behaviour and not just the words.
- Creating a personalised care plan: a plan built around your loved one’s habits, history and preferences gives each day a gentle structure. For your elderly loved one, familiar and enjoyable activities at the right times of day reduce anxiety and the idle moments when worries grow. For your family, a clear plan removes guesswork and gives everyone the same calm approach.
- Training families and carers: specialists can show you how to listen for the feeling behind an accusation, how to search together and how to redirect without arguing. Your elderly loved one meets patience instead of defensiveness, and you feel more confident, and less guilty or hurt, when hard moments come.
- Shaping a calm environment: clear layouts, good lighting, familiar objects and consistent surroundings make a space easier to understand. For your elderly loved one, fewer surprises mean fewer misreadings and less fear. For your family, a settled home usually means fewer episodes to manage.
- Offering trained, compassionate support: caregivers who understand that accusations are symptoms do not take them personally. Your elderly loved one is spared blame and keeps their dignity, while your family gets reliable support, a chance to rest and a team to turn to when the day feels heavy.
- Keeping relationships intact: with the right guidance, accusations are less likely to damage family bonds. Your loved one stays connected to the people they trust, and relatives can keep visiting with understanding and without dread.
How can families respond with empathy?
When someone you love says “someone took my money”, it is natural to feel hurt, tired or defensive. Please be gentle with yourself. Paranoia is a symptom of the condition, and the words come from fear and confusion, not from the person you have always known. Behind every accusation is an elder who is trying to feel safe.
Respond with patience, listen for the feeling and let go of the need to be right. A soft voice, a shared search and a reassuring touch will mean more to your loved one than any explanation. They may not remember the details of the day, but they will remember feeling safe and loved. You do not have to walk this path alone. With understanding and the right support, even the hardest moments can be met with kindness. Every elder is different, so please personalise these suggestions with a doctor.
