Lewy body dementia (LBD) is a complex and often misunderstood neurodegenerative condition that affects cognition, movement, and behavior. It is one of the most common forms of dementia after Alzheimer’s disease, yet it is frequently misdiagnosed or confused with other neurological conditions, particularly Parkinson’s disease.
Recent clinical research published in The Lancet Neurology highlights the growing understanding of Lewy body dementia as part of a broader spectrum of neurodegenerative disease driven by abnormal alpha-synuclein protein accumulation. You can view the original research article here:

What Is Lewy Body Dementia?
Lewy body dementia refers to disorders characterized by abnormal protein deposits called Lewy bodies in the brain. These deposits are made primarily of alpha-synuclein, a protein that disrupts normal communication between brain cells.
There are two closely related clinical presentations:
- Dementia with Lewy bodies (DLB): Cognitive symptoms appear before or at the same time as movement symptoms.
- Parkinson’s disease dementia (PDD): Movement symptoms associated with Parkinson’s disease appear at least one year before cognitive decline.
Although the timing of symptoms differs, both conditions share similar underlying pathology. Because of this overlap, they are often considered part of the same disease spectrum.
To better understand how these conditions connect, we explore this relationship in detail here:

Common Symptoms of Lewy Body Dementia
Lewy body dementia can affect multiple areas of brain function. Symptoms often include:
- Fluctuating attention and alertness
- Visual hallucinations
- Movement changes such as stiffness, slowed movement, or tremor
- Sleep disturbances, including REM sleep behavior disorder
- Autonomic dysfunction (blood pressure instability, digestive issues)
- Mood and behavioral changes
Because symptoms overlap with both Alzheimer’s disease and Parkinson’s disease, accurate diagnosis can be challenging.
Why Early Recognition Matters
Early identification of Lewy body dementia is essential for several reasons:
Medication Sensitivity
Individuals with LBD can be highly sensitive to certain antipsychotic medications, making proper diagnosis critical for safe treatment planning.
Care Planning
Understanding symptom patterns helps families create supportive environments that reduce confusion, stress, and overstimulation.
Quality of Life
While there is currently no cure, symptom-focused treatments and structured daily routines can significantly improve comfort and engagement.
Compassionate Support for Complex Conditions
At Dolan Memory Care, we recognize that Lewy body dementia presents unique challenges. The combination of cognitive changes, motor symptoms, and behavioral fluctuations requires a thoughtful, person-centered approach.
Our care model focuses on:
- Structured, calm environments
- Routine and familiarity
- Support for mobility and safety
- Emotional reassurance and dignity
By combining clinical understanding with compassionate support, families can navigate Lewy body dementia with greater confidence and clarity.
