Symptoms of Lewy Body Dementia

In contrast to other forms of dementia that initially affect specific parts of the brain, Lewy bodies may develop in several different areas of the brain, which can cause a wider range of physical and behavioral symptoms. The range of possible symptoms includes many of the same ones seen in persons with Alzheimer’s disease and Parkinson’s disease.
