What is Alzheimer's disease?

Alzheimer’s disease is the most common cause of dementia and also the best understood. It is thought to be caused by the formation of abnormal deposits of protein in the brain. These are called plaques and tangles, and they are made up of two key proteins: amyloid and tau.

Amyloid and tau are present in healthy brains, but in Alzheimer’s disease they function abnormally. Amyloid forms plaques outside cells and tau forms tangles inside them. These plaques and tangles damage the nerve cells, causing them to die. When lots of cells die, this causes the brain to shrink. Courtesy of Alzheimer's Society

What is vascular dementia?

Vascular dementia is the second most common type of dementia. It is caused by problems with the blood supply to the brain. Nerve cells require oxygen and nutrients to survive. Without them, they will become damaged or die. Courtesy of Alzheimer's Society
