He demands a drive to find his late father because memory loss and time confusion make the past feel present. A delusion is a fixed false belief that feels completely real to him. The Alzheimer's Association and Alzheimer's Society UK describe this time confusion as a common way dementia changes perception.
The U.S. National Institute on Aging advises against arguing the belief away. You can reduce fear and keep him safe.

Why does he believe his father is alive?
His brain is not lying. It has lost markers for date and order. A strong old memory can return with full emotion.
He then acts as if no time has passed. A Johns Hopkins review of 1990-2001 studies found delusions in 16%-70% of Alzheimer's patients, median 36.5%, and hallucinations in 4%-76%, median 23%, as detailed in its review of delusions and hallucinations in Alzheimer's disease. The review found they often persist and recur. Many families face the same pattern.
What should you say instead of correcting?
The U.S. National Institute on Aging advises caregivers not to argue about what the person sees, hears, or believes. Correction increases fear and resistance. If he is afraid, offer comfort first.
Keep your voice calm and your phrases short. Validation works better than proof. The U.S. National Institute on Aging recommends this sequence in its coping guidance for hallucinations and delusions. You protect dignity while you change direction.
- Validate the feeling: You miss him. You want to make sure he is okay.
- Invite a memory: Tell me about him. What did you do together?
- Redirect the body and focus: move to another room, take a short walk, or start a drink, snack, music, or simple chore.
Should you agree to drive him there?
Do not let him drive to search. According to the Alzheimer's Association's driving safety guidance, people with middle-stage Alzheimer's must stop driving.
His urgency does not mean he can drive safely. The Alzheimer's Association lists clear warning signs. Families should remove key access and provide rides instead.
- new dents or scrapes
- near misses
- getting lost in familiar places
- lane or signal errors
When should you get medical help fast?
Tell his doctor promptly about any new delusion or hallucination. The National Institute on Aging advises a review of illnesses and medicines. Infections or drugs can cause these symptoms. Bring a list of prescriptions, over-the-counter drugs, and recent fevers, falls, or poor sleep. Medication options are limited. The U.S.
Food and Drug Administration states in its Risperdal label that antipsychotics carry a boxed warning. The warning cites increased death risk in elderly patients with dementia-related psychosis, a use for which they are not approved. Do not start or adjust a sedating drug on your own. A sudden change over hours or days may be delirium, not routine dementia. Alzheimer's Society UK calls delirium a medical emergency. Seek urgent GP assessment or call NHS 111.
