Dementia is not a single illness but a group of symptoms caused by damage to the structure of the brain. Symptoms include memory loss, and problems with communication and reasoning. Dementia is associated with an ongoing decline of the brain and its abilities. The damage to the brain can be due to poor blood flow or strokes (vascular dementia) or because of damage to the internal structure of the nerve cells (Alzheimer’s disease).
Types of dementia
The most common types of dementia are Alzheimer’s disease, vascular dementia, frontotemporal dementia and dementia with Lewy bodies.
