Loss of brain function due to a series of small strokes (vascular dementia)
The two conditions often occur together.
Dementia with Lewy bodies (DLB) is a leading cause of dementia in elderly adults. People with this condition have abnormal protein structures in certain areas of the brain.
The structures and symptoms of DLB are similar to those of Alzheimer's disease, but it is not clear whether DLB is a form of Alzheimer's or a separate disease. There is no cure for DLB or Alzheimer's.
Conditions that damage blood vessels or nerve structures of the brain can also lead to dementia.
Dementia usually occurs in older age. It is rare in people under age 60. The risk for dementia increases as a person gets older.
Symptoms
Problems may involve language, memory, perception, emotional behavior or personality, and cognitive skills (such as calculation, abstract thinking, or judgment). Dementia usually first appears as forgetfulness.
