Dementia with Lewy bodies (DLB) is a form of progressive dementia. It's caused by the decay or deterioration of the tissues in the brain.

Frontotemporal dementia (FTD), a common cause of dementia, is a group of disorders that occur when nerve cells in the frontal and temporal lobes of the brain are lost. This causes the lobes to shrink. FTD can affect behavior, personality, language, and movement.

Vascular dementia is caused by decreased blood flow to brain tissue causing signs of dementia. Read on for details about this condition.
