This causes brain cells to die over time and the brain to shrink.
Overview Lewy body dementia, also known as LBD, is the second most common type of dementia after Alzheimer's disease. Protein deposits called Lewy bodies develop in nerve cells in the brain. The protein deposits affect brain regions involved in thinking, memory and movement. There are two forms of LBD that cause cognitive symptoms — dementia with Lewy bodies and Parkinson's disease dementia.
