Responding to Psychosis (Delusions and Hallucinations) in Alzheimer's

When your loved one with Alzheimer's sees, hears, or believes something that isn't real, it can be frightening and confusing for both of you. These experiences—called hallucinations and delusions—are caused by physical changes in the brain, not by stubbornness or confusion you can reason away. The good news is there are concrete, compassionate steps you can take to reduce distress, keep everyone safe, and even restore a sense of calm. This guide gives you exact words to say, actions to take, and what to avoid, so you can respond with confidence and care.

Key points

  • Hallucinations and delusions are real to the person—never argue, correct, or dismiss them.
  • Always start with non-drug approaches: validate, reassure, and redirect to a calming activity.
  • Check for physical and environmental triggers: poor lighting, uncorrected vision/hearing, shadows, noise.
  • If the person is not distressed by the hallucination or delusion, it is often best to leave them alone.
  • Document episodes to share with the doctor—patterns can guide treatment.
  • Take care of yourself: responding to psychosis is emotionally exhausting. Seek support from groups, friends, or a counselor.

What Are Hallucinations and Delusions?

Hallucinations are false sensory experiences—seeing, hearing, smelling, tasting, or feeling something that isn't there. In Alzheimer's, people most often see small children, animals, or insects, or hear voices or sounds. Delusions, on the other hand, are firmly held false beliefs. Common examples include believing someone is stealing from them, that their spouse is being unfaithful, that people are entering the house at night, or that a deceased relative has come to visit. Both are very real to the person experiencing them, and they cannot simply be talked out of them.

Why Do They Happen in Alzheimer's?

Psychosis in Alzheimer's arises from the physical damage the disease causes to the brain. As brain cells die and connections break down, the brain struggles to correctly interpret sensory information and memories. This leads to misperceptions and false beliefs. Stress, fatigue, changes in routine, poor lighting, or even uncorrected vision or hearing problems can make these episodes worse. In middle and late stages, the brain's ability to distinguish reality from imagination is significantly impaired, making delusions and hallucinations more common. It is important to remember that the person is not trying to be difficult—their brain is genuinely tricking them.

How Common Is This?

Not everyone with Alzheimer's will experience psychosis. Research suggests that about 13% of people with Alzheimer's will have hallucinations, while delusions are more common, affecting up to 30-40% in the middle and late stages. The type of delusion often changes with disease progression: earlier on, persecutory delusions (e.g., 'someone stole my wallet') are more common; later, misidentification delusions (e.g., 'that person on TV is living in my house') appear. Knowing this can help you anticipate and prepare.

Step-by-step

  1. Pause and assess your own reaction. Take a slow breath. Your loved one will pick up on your anxiety, so staying calm is your first tool. Remind yourself: this is the disease, not a personal attack or a choice.

  2. Ask yourself: 'Is my loved one bothered by this?' If they are calmly talking to someone you can't see or seem unbothered by a false belief, you may not need to intervene at all. Interrupting a peaceful hallucination can actually cause agitation.

  3. If they are distressed, use simple, validating phrases. Say things like: 'I hear you. I'll take care of this.' 'You are safe here. I'll make sure of it.' 'I'll fix this right away.' Do not argue, correct, or try to prove them wrong. Your goal is to join their reality briefly to reduce fear.

  4. Gently redirect their attention to a different activity or topic. After validating, offer a concrete, simple task: 'Can you help me fold these towels?' 'Let's go see what's for lunch.' 'Would you like to sit by the window and look at the birds?' The shift in focus can often end the episode.

  5. Check for physical triggers. Poor lighting can create shadows that look like people or insects. Make sure the room is well-lit, especially in the evening. Also check that their glasses are clean and on, and that hearing aids are working and inserted. Uncorrected vision or hearing loss can fuel hallucinations.

  6. Modify the environment to reduce triggers. If they see people in mirrors, cover or remove mirrors. If they hear voices from a fan or TV, turn it off or change the sound. If they believe someone is in the closet, open the door and show them it's empty, then close it and offer a distraction.

  7. If the hallucination or delusion involves a specific object or person, try to 'join' the delusion in a helpful way. For example, if they say there's a stranger in the house, say: 'I'll check the doors and make sure everything is locked. You're safe now.' Then walk around and 'check'—this can be very reassuring.

  8. For nighttime episodes, use a nightlight to reduce shadows. Keep a consistent bedtime routine. If they wake up frightened, approach calmly, use a soft voice, and offer comfort without questioning what they saw. Say: 'I'm here. You're safe. Let's get you back to bed.'

  9. If the behavior becomes dangerous—your loved one is trying to fight an imagined intruder, or they are at risk of falling while reacting to a hallucination—prioritize safety. Move slowly, speak gently, and if needed, step back and call for help. Do not try to restrain them physically.

  10. Document what happened: time of day, what they saw or believed, what you did, and how they responded. This pattern can help you and their doctor identify triggers and decide if medication is needed. Share this log with their clinician.

What not to do

  • Do NOT argue or try to prove them wrong. Saying 'There's no one there' or 'That's not real' will only increase their distress and make them feel more confused and defensive. Instead, validate their feeling and redirect.

  • Do NOT laugh, mock, or dismiss their experience. Even if it seems silly to you, it is terrifyingly real to them. Dismissal damages trust and can lead to agitation or aggression.

  • Do NOT ask 'Why do you think that?' or demand an explanation. Their brain cannot give a logical answer, and this question only frustrates them. Stick to simple reassurance.

  • Do NOT leave them alone if they are frightened or agitated. Your presence is a powerful calming tool. Stay nearby, speak softly, and offer a gentle touch on the arm if they accept it.

  • Do NOT immediately assume medication is needed. Non-drug approaches should always be tried first. Only if symptoms are severe, causing danger, or extremely distressing to the person should you consult a doctor about medication options.

  • Do NOT forget to take care of yourself. Responding to psychosis is emotionally draining. After the episode, take a few minutes to breathe, step outside, or call a support group. Caregiver burnout is real and can make you less able to respond calmly next time.

Practical tools

  • The 'Join and Redirect' Script

    A simple two-step verbal tool. Step 1: Join the delusion with a validating statement. Examples: 'I'll take care of this.' 'You are safe here.' 'I hear what you're saying and I'll fix it right away.' Step 2: Immediately offer a distraction or activity: 'Can you help me set the table?' 'Let's go look at the garden.' 'Would you like a cup of tea?' Keep the redirect simple and concrete.

  • The 'Safety Check' Routine

    When your loved one believes someone is in the house or that something is wrong, physically walk through the house with them. Say: 'Let's check together.' Open closets, look behind curtains, check locks. This non-confrontational action often satisfies their need for reassurance without arguing. After the check, offer a calming activity.

  • Environmental Adjustment Checklist

    Keep a printed checklist near the door: (1) Are all rooms well-lit, especially hallways and bathrooms? (2) Are mirrors covered or removed if they cause confusion? (3) Is the TV or radio on a calm channel? (4) Are glasses clean and on? (5) Are hearing aids in and working? (6) Are there any shadows from furniture or plants that could look like people? Adjust as needed.

  • The 'Comfort Kit'

    Prepare a small basket or bag with items that soothe your loved one: a soft blanket, a familiar photo album, a favorite music playlist, a scented sachet (like lavender), and a simple fidget toy. When a hallucination or delusion causes distress, offer the kit and say: 'Here, this might help you feel better.' The sensory items can ground them.

  • The 'Nighttime Safety Plan'

    For nighttime episodes: Use a dim nightlight in the bedroom and hallway. Keep a glass of water and a familiar object (like a stuffed animal or photo) on the nightstand. If they wake up frightened, approach slowly, speak in a low, calm voice, and say: 'I'm here. You're safe. Let's sit for a moment.' Offer a warm drink (non-caffeinated) and a quiet activity until they are calm enough to sleep.

  • The 'Caregiver Log' Template

    Create a simple log with columns: Date, Time, What they saw/believed, How they reacted (calm, scared, angry), What I did, What helped. Bring this log to doctor appointments. Patterns can reveal triggers (e.g., always after 5 PM, or after a bath) and help the clinician decide if medication or other interventions are needed.

Discuss with your clinician

If your loved one's delusions or hallucinations involve threats of self-harm or harm to others, seek immediate medical evaluation. This is an emergency.

If non-drug approaches have been tried consistently for several weeks and the symptoms remain severe and distressing, ask the doctor about medication options. Discuss the risks and benefits of antipsychotic medications, especially for someone with Alzheimer's.

If your loved one has a sudden onset of hallucinations or delusions, especially if accompanied by fever, confusion, or a change in consciousness, seek urgent medical care—this could be a sign of delirium caused by infection, dehydration, or medication side effects.

Ask the doctor to check for underlying medical causes: urinary tract infection, dehydration, pain, constipation, or vision/hearing problems. Treating these can sometimes resolve the psychotic symptoms without any psychiatric medication.

If your loved one is already on medication for psychosis, ask the doctor how often it should be reviewed. Many medications should be tried at the lowest effective dose and re-evaluated periodically to see if they are still needed.
