Lewy bodies often affect parts of the brain related to memory, such as the hippocampus. As a result, Lewy Body Dementia is commonly misdiagnosed as Alzheimer’s disease. Nevertheless, some symptoms are distinct. For example, symptoms like memory loss may appear shortly after an Alzheimer’s diagnosis. In contrast, those with LBD may not have memory issues until later. Some people can have both LBD and Alzheimer’s.
