Human heart, 3D coloured computed tomography (CT) scan. This is an oblique side view. The heart is a hollow muscular organ that receives and pumps blood from and around the body through the veins and arteries that branch out from its four internal chambers. The external surface of the heart includes the coronary arteries and veins that supply blood to the heart muscle. This scan includes parts of the heart's major veins and arteries, with the aorta running down right.

Why Alzheimer’s is not a single disease – and why that matters

Features

Alzheimer's disease. Series of coloured computed tomography (CT) scans of an axial section through the head of a 74-year-old patient with Alzheimer's disease. The front of the brain (brown) is at the top. Alzheimer's is a neurodegenerative disease and a common cause of dementia in the elderly. It causes brain atrophy (decrease in size), shown here by the enlarged ventricle cavities (white, at centre of brain) and the widened pale blue regions. The brain shrinkage caused by Alzheimer's disease leads to memory loss, confusion, personality changes and ultimately death. The cause of Alzheimer's disease is not known and there is no cure.
