Dementia

Dementia is a general term for loss of memory and other mental abilities severe enough to interfere with daily life. It is caused by changes in the brain.

Alzheimer’s disease is the most common form of dementia, accounting for 50 to 70 percent of cases. Other types of dementia include vascular dementia, mixed dementia, dementia with Lewy bodies and frontotemporal dementia.
