Lewy body dementia or DLB is dementia with a hangover of characteristics similar to those of Parkinson's and Alzheimer's diseases. Older people and senior citizens usually suffer from dementia of this type and DLB comprises 10 to 15% of the total dementia cases reported.

Previously this disease was referred to by several different names but now it is unanimously known as Lewy body dementia.

Lewy bodies are the brain cells in actuality. Alois Alzheimer's colleague Frederich Lewy was the first person to identify and point out the changes that take place inside brain cells and the characteristic feature that separates DLB from Parkinson's disease is that the brain cells or Lewy bodies are spread out and scattered across a large area throughout the brain.

Medical experts and physicians are still in the dark about the specific causes of this kind of dementia. Nor have risk factors been identified as yet. In rarest of the rare cases, DLB can be hereditary.
