Caption

Alzheimer's disease. Coloured gamma scans of a brain in axial section showing Alzheimer's disease. Normal active brain tissue is pink, and the arrows indicate areas of abnormally low activity. Alzheimer's disease is a degenerative brain disease which is common in elderly people. It leads to memory loss, confusion and personality changes. Death is inevitable after several years of decline. Gamma scanning, or radionuclide scanning, involves the injection of a radioactive substance into the body. This accumulates in active tissues and is detected by the radiation it emits.
