Definition
Dementia is the progressive loss of memory and various other mental functions, including the ability to:

Lewy body disease is caused by the build up of Lewy bodies. These are abnormal protein deposits inside brain cells that control certain aspects of memory and motor control. It is the second most common type of progressive dementia.
