If your parent has started seeing things that aren't there, acting out dreams, or shifting between sharp and confused within the same afternoon, you may already be hearing this term from a doctor.
These fluctuations are a real feature of the disease, not a sign your parent is getting worse in some unpredictable, random way.
Angel's Haven Care supports residents living with Lewy body dementia across our Southern California homes, built around the idea that a resident should be known, not just cared for, even as symptoms change from one day to the next. You can see all of our locations on our home page.
Think of this as lewy body dementia care explained in plain terms: the key symptoms, how this condition relates to Parkinson's disease, and what actually changes about day-to-day care.
Key Symptoms of Lewy Body Dementia
Lewy body dementia symptoms tend to cluster around a few key patterns. Cognition and alertness fluctuate, sometimes within the same day, so your parent might seem sharp in the morning and noticeably confused by afternoon. Visual hallucinations are common and often detailed, like seeing people, animals, or objects that aren't there.
Movement symptoms similar to Parkinson's disease, including tremor, stiffness, and a slower, shuffling walk, are also common. Many people with Lewy body dementia also experience REM sleep behavior disorder, where they physically act out vivid dreams, sometimes years before other symptoms appear. Fainting or lightheadedness from sudden drops in blood pressure, along with an increased risk of falls, round out the pattern many families eventually recognize.
We've broken these patterns out for quick reference further down this page.
Overlap With Parkinson's Disease
Lewy body dementia is actually an umbrella term covering two related diagnoses: dementia with Lewy bodies and Parkinson's disease dementia. Both involve the same underlying protein buildup in the brain, called Lewy bodies, and doctors often distinguish between them based on which symptoms appeared first.
Generally, if movement symptoms show up more than about a year before cognitive changes, doctors tend to diagnose Parkinson's disease dementia. If cognitive changes and movement symptoms appear closer together, dementia with Lewy bodies is the more likely diagnosis. These lewy body dementia care tips, in other words, often depend on which pattern applies to your loved one.
What Changes Over Time
Early on, the distinction between these two diagnoses can matter for how symptoms are managed. As the disease progresses, though, the care needs of both conditions tend to converge. Fluctuating cognition, movement difficulty, and sleep disturbances usually all become part of the picture over time, regardless of which came first.
How Our Caregivers Are Prepared
This lewy body dementia care caregiver guide wouldn't be complete without covering how our team actually prepares. Lewy body dementia is one of the specific conditions named in our memory care program, alongside Alzheimer's, vascular dementia, and frontotemporal dementia, so our caregivers are trained to recognize its particular patterns, not just general memory loss. That includes watching for fluctuations in alertness, noting new or worsening hallucinations, and flagging movement changes or falls to a resident's physician promptly. You can read more about what daily support looks like on our What to Expect page.
The same two to three caregivers work with a resident day to day, rather than a rotating staff. For a condition where alertness shifts within hours, that consistency means caregivers can actually tell what's a normal fluctuation and what's worth calling the physician about.
One thing we take especially seriously: many people with Lewy body dementia have a serious sensitivity to standard antipsychotic medications sometimes used for hallucinations or agitation. We make sure this is clearly communicated to any physician involved in a resident's care, since it's one of the most important things a prescriber needs to know.
Why This Gets Overlooked
Early signs, like vivid or acted-out dreams, occasional visual hallucinations, or an afternoon of confusion that clears up by evening, are easy to dismiss as normal aging or a bad night's sleep. In our experience, families often look back after a diagnosis and realize these signs had been there for a while.
Working With Neurologists
Diagnosing Lewy body dementia usually involves a neurologist, sometimes alongside a geriatric psychiatrist, since the fluctuating symptoms and hallucinations can look like several other conditions early on. Testing may include a cognitive evaluation, a review of sleep patterns, and sometimes imaging, though the exact process depends on the physician and what other conditions need to be ruled out first.
Once a resident moves in with us, we coordinate ongoing care between our caregivers, the resident's primary physician, and any specialists already involved. Dr. Jeremy V. Gomer, MD, serves as Medical Director across all six of our homes, providing an additional layer of oversight so a licensed physician is actively engaged in a resident's care, not just a signature on paperwork.
We don't diagnose or treat Lewy body dementia ourselves. Angel's Haven Care is a residential care provider, not a medical facility, so our role is to support daily life and communicate clearly with the medical team making treatment decisions.
Common Questions Families Ask
How common is what's described in Understanding Lewy Body Dementia?
Lewy body dementia is generally considered the second most common form of dementia after Alzheimer's disease. Many families are surprised by that, since it gets far less public attention than Alzheimer's, even though a meaningful number of the residents we support are living with it.
In Practice
Lewy body dementia is common enough that most experienced dementia caregivers recognize its patterns, even when the diagnosis itself is still unfamiliar to many families.
Does a physician help oversee this type of care?
Yes. A neurologist or physician typically oversees diagnosis and treatment decisions, including medication choices, which need particular care given the sensitivity many people with Lewy body dementia have to certain drugs. Our caregivers support day-to-day needs and stay in close contact with that physician, but medical decisions stay with the medical team.
How do I know if my loved one needs this level of support?
The clearest way to know is to bring specific observations to your loved one's physician or neurologist: fluctuating confusion, visual hallucinations, movement changes, falls, or acting out dreams during sleep. These patterns, especially together, are worth raising directly rather than waiting to see if they resolve on their own.
