Recognizing the First Signs of Lewy Body Dementia
Watching someone you care about change in ways that are hard to explain can be unsettling. Maybe they’re seeing things that aren’t there, or their thinking seems sharp one hour and foggy the next. These kinds of shifts can leave families searching for answers.
Lewy body dementia is a progressive condition that affects thinking, movement, and behavior, and it often shows early warning signs that are related to changes in those areas. At The Enclave of Franklin, we know that knowing what to look for can help you take action sooner rather than later, and exploring memory care support options early can make a real difference for your family.
Early Warning Signs of Lewy Body Dementia
One of the most telling early signs of Lewy body dementia is fluctuating cognition. A person might seem completely alert and clear-headed in the morning, then confused and disoriented by the afternoon. This kind of inconsistency is different from the more gradual memory decline often associated with other forms of dementia.
Visual hallucinations are another hallmark sign, and they tend to appear earlier in Lewy body dementia than in other types. A person might describe seeing people, animals, or objects that aren’t actually there. These experiences often feel very real to them, which can be distressing for both the individual and their family.
Sleep disturbances are also common and worth paying attention to. A condition called REM sleep behavior disorder can cause people to physically act out their dreams, sometimes moving, talking, or even shouting during sleep. This symptom can actually appear years before other signs of Lewy body dementia become noticeable.
Physical Symptoms That Often Appear First
Movement and Balance Changes
Lewy body dementia can affect the body as much as the mind. You might notice that a loved one has developed a shuffling walk, stiffness in their arms or legs, or a slight tremor. These movement changes can closely resemble what you’d see in Parkinson’s disease, which is part of what makes Lewy body dementia tricky to identify.
Slowed movement and balance problems also raise the risk of falls, which is a real concern for older adults. If someone seems less steady on their feet or takes longer to get up from a chair than they used to, that change deserves attention.
Autonomic Nervous System Changes
The autonomic nervous system controls functions your body handles automatically, like blood pressure and digestion. In Lewy body dementia, this system can be disrupted in ways that cause dizziness when standing up, fainting spells, or sudden drops in blood pressure.
Digestive issues and changes in bladder control are also possible early signs. These symptoms are sometimes chalked up to aging or other health conditions, so connecting them to a broader pattern of changes is important when speaking with a physician.
How Lewy Body Dementia Differs from Other Forms
Lewy body dementia shares some overlap with both Alzheimer’s and Parkinson’s disease, but it has its own distinct profile. The fluctuating cognition, where a person has noticeably good and bad periods, sets it apart from the more consistent memory loss seen in Alzheimer’s disease. The visual hallucinations also tend to show up earlier than they do in other types of dementia.
The movement symptoms, like stiffness and tremors, mirror what happens in Parkinson’s disease. In fact, some people receive a Parkinson’s diagnosis before Lewy body dementia is identified. Understanding these distinctions, as outlined in key facts about Lewy body dementia, can help guide a more accurate diagnosis.
What to Do After You Notice These Signs

Steps Toward a Diagnosis
If you’ve noticed a combination of these signs in someone you love, the most helpful thing you can do is start documenting them. Write down specific behaviors, when they happen, and how long they last. Patterns over time give physicians much more to work with than a general description.
From there, scheduling an appointment with a physician is the right next move. Bring your notes and be prepared to describe what you’ve observed in detail. A thorough evaluation can help rule out other conditions and point toward the right support.
Support Options Worth Considering
Memory care communities offer a structured environment designed to meet the daily needs of those living with dementia-related conditions. For families who need some temporary relief while figuring out next steps, respite care can provide short-term support in a safe, caring setting.
