What Is Lewy Body?
7. Differences from Alzheimer’s Disease
Alzheimer’s disease is another form of dementia associated with unwanted proteins in the brain. However, the beta-amyloid and tau proteins in Alzheimer’s patients are different from Lewy bodies, and the cause and effect relationship of their presence is not entirely clear. Some experts suspect the body may create the protein deposits to protect the brain from the real culprit, inflammation.
Patients with Alzheimer’s disease experience a steady decline in memory and cognitive function, as compared to the day-to-day fluctuations in the mental ability of those with LBD. Alzheimer’s patients also do not experience tremors and trouble walking. However, the 40% of Alzheimer’s patients who also have Lewy bodies, do experience these symptoms.
