Understanding hallucinations, fluctuations, and everyday challenges — and what caregivers can actually do
Lewy body dementia (DLB)
Lewy body dementia (DLB) affects attention, perception, and daily functioning in ways that can feel unpredictable. This guide explains the most common symptoms and offers practical strategies for managing everyday situations.

If you are caring for someone with Lewy Body Dementia, you may have experienced this:
One moment, the person seems present and aware.
The next, everything changes.
They may:
- See things that are not there
- Become suddenly confused
- Struggle with attention and alertness
- Have restless nights or vivid dreams
- Move slower or seem physically stiff
This can feel unpredictable and difficult to understand.
But it is not random.
It is the nature of Lewy Body Dementia (LBD).
Why Lewy Body Dementia Feels So Unpredictable
Lewy Body Dementia affects more than memory.
It impacts:
- Attention and alertness (fluctuations)
- Visual processing (hallucinations)
- Movement and coordination
- Sleep regulation
- Processing speed and understanding
This creates a pattern many caregivers recognise:
“I never know who I will meet today.”
That uncertainty is often one of the most challenging parts of daily care.
What Makes Lewy Body Dementia Different
In many types of dementia, changes are gradual.
In Lewy Body Dementia, changes are often:
- Sudden
- Fluctuating
- Unpredictable
The person may function well in one situation — and struggle shortly after.
This is not simply “good days and bad days.”
It can change hour by hour.
Why Common Approaches Often Don’t Work
When situations become difficult, caregivers often try to:
- Explain more clearly
- Correct misunderstandings
- Repeat instructions
- Increase structure
Sometimes this helps.
But often, it increases stress.
Because the brain is struggling to:
- Interpret reality consistently
- Process information at a stable pace
- Regulate attention and perception
This means:
- The reaction happens before reasoning
- Logic does not always calm the situation
A Different Approach: Functional Supportive Communication
Instead of correcting or pushing, the focus shifts.
From:
- Fixing behaviour
- Arguing about what is real
- Expecting consistency
To:
- Supporting the person in the moment
- Adjusting to their current level of function
- Creating safety through calm, rhythm, and presence
This approach is inspired by practical dementia care and Marte Meo principles.
