Lewy Body Dementia

Lewy body dementia and AD are two degenerative diseases that seriously affect mental intelligence, but the symptoms are similar between the two. It is the second most common type of progressive dementia after Alzheimer’s disease. Protein deposits, called Lewy bodies, develop in nerve cells in the brain regions involved in thinking, memory and movement. Lewy body dementia causes a progressive decline in mental abilities always along with the visual hallucinations and changes in alertness and attention.
