If your loved one is seeing people who aren’t there…
or insisting someone has stolen their wallet…
or whispering that strangers are in the house…
You are not losing your mind.
And neither are they.
Hallucinations and delusions are extremely common in Lewy Body Dementia (LBD) — and often appear earlier and more vividly than in other types of dementia.
Let’s talk about what’s actually happening.
First: What’s the Difference?
Hallucinations
Seeing, hearing, or sensing something that isn’t physically present.
Common in LBD:
-
People standing in the room
-
Children or animals
-
“Shadow figures”
-
Hearing voices or music
-
Feeling someone touch them
Visual hallucinations are especially common in Lewy.
Delusions
Fixed false beliefs that feel completely real.
Examples:
-
“Someone stole my money.”
-
“You’re not my spouse.” (Capgras)
-
“There are intruders in the house.”
-
“You’re having an affair.”
-
“This isn’t my home.”
These are not misunderstandings.
They are firmly believed realities.
Why Hallucinations Happen in Lewy Body Dementia
Lewy Body Dementia affects the brain systems responsible for:
-
Visual processing
-
Attention
-
Perception
-
Sleep regulation
-
Dopamine balance
That combination creates the perfect storm for:
-
Misinterpreting shadows
-
Filling in missing visual information
-
Blurring dream and wake states
-
Heightened suspicion
-
Misidentifying familiar people
In other words:
The brain is trying to make sense of incomplete data — and it fills in the blanks.
What It Feels Like From Their Side
Imagine your brain confidently showing you something.
You see it clearly.
You feel it.
You react to it.
Now imagine someone calmly telling you:
“That’s not real.”
You would likely defend your reality too.
That’s why arguing rarely works.
How to Respond (Without Making It Worse)
This is the part caregivers desperately need.
1️⃣ Do Not Argue About Reality
Instead of:
“That’s not there.”
“You’re imagining things.”
Try:
“I don’t see it, but I can tell it feels real to you.”
“That sounds unsettling.”
“You’re safe. I’m right here.”
You don’t have to agree with the hallucination.
You respond to the emotion.
2️⃣ Assess: Is It Distressing?
Not all hallucinations are frightening.
Sometimes people with LBD see:
-
Children playing
-
Animals in the yard
-
A quiet figure in a chair
If it’s not distressing or dangerous, you may not need to “fix” it.
Sometimes gentle neutrality is enough.
3️⃣ Improve the Environment
Visual hallucinations often worsen with:
-
Dim lighting
-
Shadows
-
Clutter
-
Mirrors
-
Patterned wallpaper or flooring
Try:
-
Soft warm lighting
-
Closing curtains at dusk
-
Removing mirrors at night
-
Simplifying busy spaces
Small environmental changes can reduce triggers dramatically.
4️⃣ Use Calm Reassurance Over Logic
Fear doesn’t respond to correction.
It responds to safety.
Your tone, posture, and pacing matter more than your words.
Slow your voice.
Move gently.
Lower stimulation.
Your nervous system is the stabilizer.
5️⃣ Watch for Medical Triggers
Sudden increase in hallucinations may be caused by:
-
Infection (especially UTIs)
-
Dehydration
-
Medication changes
-
Sleep deprivation
-
Hospital stays
If symptoms spike suddenly, consult your medical provider.
6️⃣ When Delusions Target You
This one hurts.
Accusations. Suspicion. Jealousy.
“You’re not my wife.”
“You’re stealing from me.”
These are brain-based misidentifications — not character judgments.
It doesn’t make it less painful.
But it may help you hold it differently.
If safety allows, respond with calm presence rather than defense.
A Special Note About Capgras Syndrome
Capgras — the belief that a loved one has been replaced by an impostor — is particularly associated with Lewy Body Dementia.
It often worsens in:
-
Low lighting
-
High stress
-
Fatigue
-
Hospital environments
If Capgras is happening:
-
Avoid confrontation
-
Step out briefly and re-enter
-
Adjust lighting
-
Change clothing (sometimes visual reset helps)
And most importantly:
Protect your own emotional health.
This one is heavy.
When Hallucinations Become Dangerous
Seek medical guidance if:
-
Fear escalates into aggression
-
There’s risk of harm
-
Sleep disappears completely
-
Paranoia becomes extreme
-
Behavior changes abruptly
There are medication options that may help — though LBD is uniquely sensitive to certain antipsychotics, so medical expertise matters greatly.
A Gentle Truth
Hallucinations and delusions in Lewy Body Dementia are not stubbornness.
They are neurological misfires.
You are not failing because you can’t reason someone out of them.
You are responding to a brain condition, not a debate.
That is an entirely different skill set.
And you are learning it.
