Alzheimer's disease is the most common cause of late-life dementia. The disorder is thought to be caused by a protein known as the amyloid-beta protein, or Abeta, which clumps together in the brain, forming plaques that are thought to destroy neurons. This destruction starts early, too, and can presage clinical signs of the disease by up to 20 years.
