When a parent is diagnosed with Lewy body dementia (LBD), it can feel like the ground has shifted beneath your feet. Unlike some other forms of dementia, LBD can cause symptoms that fluctuate dramatically from one day to the next — clear and talkative in the morning, deeply confused by afternoon. Add to that the possibility of vivid hallucinations, movement difficulties, and sleep disturbances, and it becomes clear why families often describe caring for a parent with LBD as one of the most challenging experiences of their lives.
If you are in this situation, you are not alone, and you do not have to figure it all out at once. Understanding what Lewy body dementia actually looks like day to day is the first step toward building care that genuinely helps your parent feel safe, comfortable, and connected to the people they love.
What Makes Lewy Body Dementia Different
Lewy body dementia is caused by abnormal protein deposits — called Lewy bodies — that disrupt the brain's normal functioning. It shares features with both Alzheimer's disease and Parkinson's disease, which can make it harder to diagnose and sometimes harder to explain to friends and extended family.
A few characteristics that set LBD apart include:
- Fluctuating cognition. Your parent may seem almost like themselves on some days, then struggle to hold a conversation or recognize familiar faces on others. These swings are not a sign that things are getting worse overnight — they are part of the condition.
- Visual hallucinations. Many people with LBD see things that are not there — often people, animals, or objects. These experiences can feel very real to your parent and may or may not cause distress. Arguing about whether the hallucination is real rarely helps and can increase agitation.
- Parkinsonism symptoms. Stiffness, a shuffling gait, and tremors are common, which raises the risk of falls and makes mobility support an important part of daily care.
- REM sleep behaviour disorder. Your parent may act out vivid dreams — sometimes loudly or physically — while asleep. This is a recognized feature of LBD and worth discussing with their physician.
- Sensitivity to certain medications. This is critically important: some antipsychotic medications that are used for other conditions can cause severe reactions in people with LBD. Always inform any new healthcare provider of the diagnosis before any medication is started.
Building a Reassuring Daily Routine
Consistency is genuinely protective for someone living with Lewy body dementia. When the environment and the schedule are predictable, it reduces the mental effort your parent has to spend orienting themselves — and that can mean calmer, clearer moments throughout the day.
Practical things that tend to help include:
- Keeping wake-up times, mealtimes, and bedtime as consistent as possible, even on weekends.
- Reducing clutter and loud background noise, which can worsen confusion and agitation.
- Using soft, even lighting — harsh shadows can sometimes make hallucinations worse.
- Keeping familiar objects and photographs visible, as they can provide gentle grounding cues.
- Avoiding rushing. People with LBD often need extra time to process what is being said or asked of them. A slow, calm pace makes transitions much easier.
Responding to Hallucinations with Compassion
If your parent tells you there is a child sitting in the corner, or that someone is standing in the garden, the natural instinct is to correct them. In most cases, though, gentle redirection works better than confrontation. Ask how your parent feels about what they are seeing. If they are not frightened, you may not need to intervene at all. If they are distressed, calmly acknowledging their feelings — without confirming or denying the hallucination — and then gently steering their attention elsewhere can help settle the moment.
It is worth speaking with their care team about strategies tailored to your parent's specific experiences, as hallucinations in LBD can vary widely.
Safety at Home: A Few Key Areas to Address
Because LBD affects both cognition and movement, the home environment deserves a careful look. Some of the most common areas families address include:
- Fall prevention. Remove throw rugs, ensure good lighting in hallways and bathrooms, and consider grab bars near the toilet and in the shower. A physiotherapist or occupational therapist can offer a formal home assessment.
- Kitchen safety. Stove use can become risky during periods of confusion. Automatic stove shut-off devices are worth considering, as is having support on hand during meal preparation.
- Wandering and night-time safety. Sleep disruptions are common with LBD. Door alarms or simple sensor mats near the bed can alert a family caregiver if your parent gets up during the night.
How Regular Companion Care Can Help
One of the most meaningful things you can offer a parent with Lewy body dementia is a steady, familiar presence. Unfamiliar faces and changing routines tend to increase anxiety and confusion, which is why having the same caregiver visit consistently each week can make a real difference.
A trusted companion caregiver can help with light meal preparation, gentle conversation, accompaniment on a short walk, medication reminders, and simply being a calm, reassuring presence during the hours when family members cannot be there. They can also keep you updated on how your parent is doing day to day — noticing small changes that might not be obvious during a Sunday visit.
If you are exploring what this kind of support might look like for your family, Hearthlane is a GTA and York Region companion-care service launching in 2026. You are welcome to join the waitlist now so we can be in touch as we get closer to opening — there is no obligation, and it is a good way to stay informed as you plan ahead.
Taking Care of Yourself Along the Way
Caring for a parent with Lewy body dementia is a long road, and the emotional weight of it — the grief, the unpredictability, the sheer logistics — can be exhausting. Connecting with a support group specifically for LBD caregivers (the Lewy Body Dementia Association has resources, and your parent's neurologist or geriatrician may know of local options in Ontario) can help you feel less alone in what you are navigating.
You do not have to provide every hour of care yourself. Asking for help — from family, from community supports, or from a companion-care service — is not giving up. It is often what makes it possible to keep going, and to keep showing up for your parent with the patience and love they need from you.
