What Is Lewy Body?
6. Differences from Parkinson’s Disease
Doctors disagree on the relationship between LBD and Parkinson’s disease. Some consider them to be separate conditions, while others suggest they are two points on a spectrum of Lewy body disorders. The same buildup of proteins in the brain causes both, and both eventually result in the same symptoms.
The main difference between Parkinson’s disease and LBD is the speed at which dementia develops. In both disorders, physical symptoms such as muscle tremors and difficulty walking appear first. For those with LBD, cognitive symptoms develop within one year. People with Parkinson’s, in contrast, can experience physical symptoms for years without dementia.
