Alzheimer's disease brain, coloured computed tomography (CT) scan. This is the brain of an 81 year old woman. The front of the brain is at top. Alzheimer's disease is a common cause of dementia in the elderly. It causes loss of brain mass, which causes the fluid-filled ventricles (orange, at centre) to grow larger as the brain shrinks. Orange gaps in brain tissue are also seen. This brain shrinkage leads to memory loss, disorientation, confusion and ultimately death. There is no cure for the condition. CT scanning uses multiple X- ray beams passed through the body at different angles to build up slice images through the area being studied.
