Causes of dementia

There are many causes of dementia, including cerebrovascular disease, Lewy Body Disease, injuries, or a blow to the head. Alzheimer's disease is considered as a form of dementia, and Alzheimer's is approximately 60-80 percent of dementia cases.

Dementia is not just one disease. It is an umbrella term that refers to different conditions like vascular dementia, frontotemporal dementia, and other memory-related disorders.
