What is Dementia?
- Dementia is not a specific disease but is rather a general term for the impaired ability to remember, think, or make decisions that interferes with doing everyday activities.
- Alzheimer’s disease is the most common type of dementia. However, there are several other types of dementia, each with its own underlying causes. Some of the common types of dementia include: Vascular Dementia, Lewy Body Dementia, Frontotemporal Dementia, and Mixed Dementia.
- Though dementia mostly affects older adults, it is not a part of normal aging.
Q1) What is Vascular Dementia?
Vascular dementia is the second most common form of dementia after Alzheimer's disease. It's caused when decreased blood flow damages brain tissue. Blood flow to brain tissue may be reduced by a partial blockage or completely blocked by a blood clot. Without proper blood flow, needed oxygen and nutrients aren’t delivered and brain tissue is damaged.
