Few moments in dementia caregiving sting like this one. You drive over to help, and your mother tells you that you took her purse. Or your father insists there are strangers in the backyard. Or a parent you have cared for every day for a year suddenly does not trust you.
These experiences are common in Alzheimer’s disease and other dementias. They come from changes in the brain, not from anything you did. Understanding what is happening, and what to check first, can make them less frightening for both of you.
Hallucinations, delusions and paranoia: what’s the difference?
| Term | What it means | What it might sound like |
|---|---|---|
| Hallucination | Seeing, hearing, smelling, tasting or feeling something that is not there | “There’s a man standing in the corner.” “Do you hear the children outside?” |
| Delusion | A firm belief in something that is not true | “This isn’t my house.” “My husband is having an affair.” |
| Paranoia | A type of delusion built on suspicion that others mean harm | “You’re stealing my money.” “The neighbors are watching me.” |
The Alzheimer’s Association explains that suspicions and false accusations often grow out of memory loss itself. When your parent cannot remember putting their purse in the closet, the brain looks for an explanation, and “someone took it” can feel like the only one that makes sense.
First, rule out other causes
Before assuming a new hallucination or delusion is “just the dementia,” talk with your parent’s doctor. The Alzheimer’s Association recommends a medical evaluation when hallucinations begin, to rule out other causes and decide whether treatment is needed. Possible contributors include:
- Infections, including urinary tract, bladder and kidney infections
- Dehydration
- Pain that your parent may not be able to describe
- Vision or hearing problems. A dirty pair of glasses or a failing hearing aid can turn shadows and background noise into something frightening
- Medication side effects or interactions. A full medication review is worth asking for
A sudden change over hours or days is different from a slow change over months. If your parent becomes much more confused, agitated or suspicious very quickly, call their doctor promptly.
If anyone is in immediate danger, including your parent, call 911.
How to respond in the moment
Guidance from the National Institute on Aging and the Alzheimer’s Association points in the same direction: respond to the feeling, not the facts.
What tends to help
- Stay calm and reassuring. Your tone often matters more than your words.
- Acknowledge the feeling. “That sounds frightening” or “I can see you’re worried about your purse” does not agree with the belief. It shows you are on their side.
- Be honest without arguing. The Alzheimer’s Association suggests something like: “I know you see something, but I don’t see it.”
- Keep answers short. Long explanations are hard to follow and can add to the frustration.
- Redirect gently. Offer to help look, then move toward a walk, a snack, music or another room.
What tends to make it worse
- Arguing, or trying to prove with logic that the belief is wrong
- Taking the accusation personally, however personal it sounds
- Dismissing the experience (“There’s nothing there, stop it”)
Practical changes that prevent repeat episodes
Small adjustments at home often reduce how often these moments happen:
- Keep duplicates. If the same item keeps “going missing,” such as a purse, wallet, glasses or keys, keep a spare so it can be “found” quickly.
- Learn the hiding places. Many people with dementia tuck valuables away for safekeeping and then forget. Check drawers, pockets and under cushions first.
- Look at the lighting. Shadows, glare and dim corners can be misread. Brighter, even lighting in the late afternoon may also help with sundowning.
- Check mirrors and screens. A reflection or a television show can seem like a stranger in the room. Covering a mirror or changing what is on TV sometimes solves the problem.
- Keep a simple log. Note the time, what happened just before, and what helped. Patterns often appear, and the log is useful to bring to the doctor.
A word about medication
Non-drug approaches are the recommended first step. When symptoms are severe, distressing or dangerous, a doctor may consider medication. The Alzheimer’s Association notes that antipsychotic medications are associated with an increased risk of stroke and death in older adults with dementia, so the decision should weigh risks and benefits carefully with your parent’s doctor. Never start, stop or change a medication without medical guidance.
Taking care of yourself
Being accused by someone you love, especially when you are the one holding everything together, is exhausting. It helps to remember that the accusation usually lands on the person who is closest, precisely because you are the one who is always there. Support groups, the Alzheimer’s Association 24/7 Helpline at 1-800-272-3900, and our article on preventing caregiver burnout are good places to start. When these behaviors come with anger during personal care, our guide to aggression and resistance to care may also help.
When home is no longer enough
Paranoia and hallucinations alone do not mean your parent needs to move. They become a reason to consider more support when they are frequent, when they put your parent or others at risk, when they happen at night and no one is sleeping, or when the family caregiver can no longer keep up. Our guide to the stages of dementia explains how needs tend to change over time.
In a small memory care home, a consistent team that knows your parent’s routines and triggers can often spot the pattern early and respond calmly. Shepherd Premier provides memory care in residential homes in Dixon and Sterling. You can read more about our approach to memory care.
Frequently asked questions
Why does my mother accuse me of stealing?
Most often because she cannot remember where she put something, and her brain fills the gap with an explanation. The accusation tends to land on whoever is closest. It is a symptom of the disease, not a judgment of you.
Should I correct my parent when they see something that isn’t there?
Arguing rarely helps. If the hallucination is not upsetting, you may not need to do anything. If it is upsetting, acknowledge the feeling, reassure your parent and redirect their attention.
Are hallucinations a sign dementia is getting worse?
They can be part of the disease’s progression, but they can also be caused by infections, medications, pain or vision and hearing problems. That is why a doctor’s evaluation comes first, especially when symptoms are new or appear suddenly.
When is it an emergency?
If your parent or anyone else is at risk of being hurt, call 911. For a sudden change in confusion or behavior that is not immediately dangerous, call your parent’s doctor the same day.
You don’t have to handle this alone. If you want to talk through what you are seeing at home, call or text (847) 961-2551, schedule a private tour or care conversation, or start with our short care assessment.
