Symptoms That Distinguish Lewy Body Dementia From Alzheimer's Disease

At Circle of Life Care, nestled in the heart of Arizona, we deeply understand the unique challenges presented by dementia. While Alzheimer's is widely known, another critical condition we encounter is Lewy Body Dementia (LBD). Although both Alzheimer's and LBD are forms of dementia, they have distinct symptoms that set them apart. In this blog, we'll explore these differences to enhance awareness and support for those living with these conditions.


Visual Hallucinations: A Hallmark of Lewy Body Dementia

One of the most significant symptoms distinguishing Lewy Body Dementia from Alzheimer's is the presence of visual hallucinations. These can be vivid, detailed, and sometimes distressing for individuals. Unlike Alzheimer's, where hallucinations are less common and occur in later stages, LBD patients often experience them early in the disease progression, making it a crucial diagnostic indicator.


Motor Skills and Physical Movement

Lewy Body Dementia is closely related to Parkinson's disease and shares many motor symptoms. Individuals with LBD may exhibit Parkinsonian features like muscle rigidity, tremors, and a shuffling gait. In contrast, Alzheimer's typically doesn't affect motor skills until the later stages. This early onset of physical symptoms in LBD is a vital distinction for caregivers and medical professionals.


Cognitive Fluctuations

Another defining characteristic of Lewy Body Dementia is the fluctuation in cognitive abilities. Those with LBD may experience significant variations in attention and alertness from hour to hour or day to day. Alzheimer's, however, generally shows a more gradual and steady decline in cognitive functions without these dramatic fluctuations.


REM Sleep Behavior Disorder

REM Sleep Behavior Disorder is often linked with Lewy Body Dementia. This condition involves acting out dreams, which can include talking, yelling, or even physically moving while asleep. This symptom is rare in Alzheimer's, making it a critical point of differentiation for Lewy Body Dementia.


Quick Reference: Key Differences Between Lewy Body Dementia and Alzheimer's

  • Visual Hallucinations:

    • LBD: Early and frequent.

    • Alzheimer's: Less common, typically in later stages.

  • Motor Skills and Movement:

    • LBD: Parkinsonian symptoms like tremors, and muscle rigidity, early in the disease.

    • Alzheimer's: Motor skills are generally affected in later stages.

  • Cognitive Fluctuations:

    • LBD: Significant, rapid changes in attention and alertness.

    • Alzheimer's: More gradual, steady cognitive decline.

  • Sleep Disturbances:

    • LBD: REM Sleep Behavior Disorder is common.

    • Alzheimer's: Less likely to experience REM sleep disturbances.

  • Rate of Progression:

    • LBD: Can vary widely, often more rapid than Alzheimer's.

    • Alzheimer's: Typically more gradual progression.
