“Lewy body dementia (LBD) is a type of dementia in which Lewy bodies are present in your brain. Lewy bodies are clumps of proteins that build up inside certain neurons (brain cells). They cause damage to neurons in the areas of your brain that affect mental capabilities, behavior, movement and sleep.  Lewy body dementia is a progressive disease, meaning symptoms start slowly and get worse over time.

In people over the age of 65, LBD is one of the most common causes of dementia. The symptoms of LBD may closely resemble those of other neurological conditions, including Alzheimer’s disease and Parkinson’s disease.”.
